PepSense Terms of Service

These Terms of Service (the "Terms") are a binding agreement between you and PepSense, Inc. ("PepSense", "we", "us", or "our"). They govern your use of pepsense.ai, the PepSense mobile applications, and any related features, content, and services (together, the "Service").

Read Section 5 carefully. PepSense is a research and education platform. It does not provide medical advice, medical care, or any healthcare service, it does not recommend doses or create dosing protocols, and it does not sell or supply any compound. The app includes a reconstitution calculator, which is an arithmetic unit-conversion utility that operates only on numbers you enter. It is described in Section 7. It is not dosing guidance and it is not medical advice. If you are looking for medical guidance, talk to a licensed healthcare provider.

If you use the PepSense iOS app, additional terms apply, including the End User License Agreement at pepsense.ai/eula and the Apple terms described in Section 22. Section 19 of these Terms governs dispute resolution for all users, including iOS users, and controls over any inconsistent provision in any other PepSense document.

If you do not agree to these Terms, do not use the Service.

1. Agreement to These Terms

By creating an account, downloading or using the PepSense app, subscribing to a paid plan, or otherwise accessing the Service, you agree to these Terms. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization, and "you" includes both you and that organization.

These Terms work alongside a few other documents. To avoid any doubt about which document wins, the order of precedence below applies, and it is stated the same way in every PepSense document.

• Privacy Policy, at pepsense.ai/privacy: how we collect, use, share, retain, and delete your information.
• Consumer Health Data Privacy Policy, at pepsense.ai/consumer-health-data-privacy: a standalone notice covering consumer health data, published separately and linked separately from our homepage as Washington and Nevada law require.
• End User License Agreement (EULA), at pepsense.ai/eula: the license terms for the PepSense iOS app, including the terms Apple requires.
• If we offer text messaging and you opt in, the messaging terms presented to you at the time you opt in apply to those messages. We do not send marketing text messages unless you have separately agreed to receive them.

2. What PepSense Is, and What It Is Not

PepSense has three core functions. First, it answers questions about peptides and related compounds by summarizing published scientific literature and providing citations. Second, it lets you keep a private log of a protocol you have decided to follow, including compounds, dose events you record, weight entries, side effects, goal metrics, and progress photos. Third, it provides a reconstitution calculator, which is an arithmetic unit-conversion utility that converts numbers you enter into a corresponding volume or syringe-unit equivalent, and does nothing else. Section 7 describes the calculator and its limits in detail.

That is the whole product. Being clear about what it is not is just as important.

• PepSense is not a healthcare provider, medical practice, clinic, or telehealth service.
• PepSense is not a pharmacy, compounding pharmacy, manufacturer, compounder, distributor, reseller, prescriber, or vendor of any compound. We do not supply any compound, diluent, vial, syringe, or other material.
• PepSense does not diagnose, treat, cure, prevent, or monitor any disease or condition.
• PepSense does not prescribe anything and does not employ clinicians to review your data, your questions, or anything you enter into the calculator.
• PepSense does not recommend doses. It does not suggest, select, validate, verify, or approve any dose, amount, titration schedule, route, or protocol, it does not create dosing protocols or frequency guidance, and it does not tell you what to take or when to take it.
• The reconstitution calculator performs arithmetic on numbers you supply and nothing more. It does not know or evaluate whether any amount is appropriate for you or for anyone, and its output is not a recommendation, an approval, or medical advice. See Section 7.
• PepSense is not a medical device, and is not intended to function as one.
• PepSense is not a medical record system. Nothing in your log is a medical record, and no provider is monitoring it.

3. Eligibility

You must be at least 18 years old to create an account or use the Service. There is no version of PepSense for minors, and we do not knowingly allow anyone under 18 to register. If we learn that an account belongs to someone under 18, we will close it and delete the associated data.

By using the Service you represent and warrant that all of the following are true.

• You are 18 years of age or older and can form a binding contract.
• You are not barred from using the Service under the laws of your jurisdiction.
• You are not located in a region that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" region, and you are not listed on any U.S. Government list of prohibited or restricted parties.
• You will comply with all laws that apply to you, including laws governing the possession, purchase, import, and use of any compound you may research or log.

4. Your Account

You need an account to use most features. You can register with an email address and password, or with Sign in with Apple or Google. You are responsible for the accuracy of the information you provide and for keeping your credentials secure.

You are responsible for everything that happens under your account. Tell us promptly at support@pepsense.ai if you believe your account has been accessed without your permission. We are not liable for losses caused by unauthorized use of your account that results from your failure to safeguard your credentials.

Your account is for you personally. Do not share it, sell it, or let anyone else use it, and do not create an account on behalf of another person.

5. Not Medical Advice: Research and Education Only

This is the most important section in these Terms. Read it before you use the Service.

PepSense provides research and educational information, and an arithmetic calculator that operates on numbers you enter. It does not provide medical advice, and nothing in the Service is a substitute for the judgment of a licensed healthcare professional who knows your history, your medications, your conditions, and your circumstances.

Check with a doctor in addition to using the app and before making any medical decision. That means before starting, stopping, changing, combining, or timing any compound, medication, dose, schedule, or protocol, and before acting on anything you read, ask, log, calculate, or see charted in PepSense. Never disregard professional medical advice, and never delay seeking it, because of something you read or computed in PepSense.

The Service is designed to be used alongside a clinician, never instead of one. If you do not have a provider you can ask, that is a reason to find one, not a reason to rely on the Service.

• No doctor-patient relationship is created by using the Service, by asking a question, by logging a protocol, by using the calculator, or by contacting us. We do not treat you, we do not monitor you, and we do not have a duty of care over your health decisions.
• The Service does not diagnose any condition, does not tell you whether a compound is appropriate for you, and does not recommend a dose, an amount, a schedule, a stack, a titration plan, a route of administration, or a course of treatment.
• The Service will not tell you how much to take, how often to take it, or whether to take anything at all. The reconstitution calculator converts figures you supply into a corresponding volume or syringe-unit equivalent. That conversion is arithmetic, not advice. It is not a statement that the amount you entered is safe, correct, lawful, or appropriate for you, and it is not a substitute for a licensed clinician or a pharmacist. See Section 7.
• Information about a compound is not a recommendation to use it, an endorsement of it, or a statement that it is safe, effective, legal, or appropriate for you or for anyone.
• We make no claim about the safety, efficacy, purity, legality, or suitability of any compound, product, protocol, or vendor.
• The Service is not for use in an emergency, for urgent symptoms, or for any situation where delay could cause harm.

We do not sell or supply anything

PepSense does not sell, supply, source, distribute, compound, manufacture, ship, or dispense any peptide, drug, supplement, diluent, vial, syringe, or other substance or material. We do not operate a marketplace, we do not list or rank vendors, we do not publish vendor reviews, coupons, or affiliate links, and we do not connect you with anyone who sells these compounds.

Nothing in the Service is an offer, solicitation, encouragement, or instruction to obtain, possess, or use any compound. What you choose to obtain, prepare, or use is your decision alone, made outside the Service.

Regulatory status of the compounds discussed

Many of the compounds referenced in the scientific literature that PepSense summarizes are not approved by the U.S. Food and Drug Administration for any use, or are not approved for the use being discussed. Some are sold only as research chemicals labeled "for research use only, not for human consumption." Some appear on FDA lists restricting their use in compounded drug products. Some are lawful to possess in one jurisdiction and not in another.

PepSense reports what published research says. It does not tell you that any compound is legal for you to obtain, or appropriate for you to take. Determining the legal status of anything you obtain, and the medical appropriateness of anything you take, is your responsibility and your provider's.

Human use of unapproved compounds carries real risk

Much of the published research on these compounds is preclinical, conducted in cell models or in animals, or based on small human studies. Preclinical results frequently do not translate to humans. Long-term safety data is often absent entirely. Products sold outside a regulated pharmacy supply chain may be mislabeled, contaminated, underdosed, or overdosed, and PepSense has no ability to verify what you have obtained, what is in it, or whether the figures printed on its label are accurate.

You use this information at your own risk, and you assume that risk knowingly. See Section 14.

6. AI-Generated Answers, Accuracy, and Citations

Answers in PepSense are generated by artificial intelligence. When you ask a question, we retrieve passages from a corpus of published scientific literature and use large language models operated by third-party providers to produce a summary with citations. You are interacting with an AI system, not with a person, and no clinician, pharmacist, scientist, or other human reviews an answer before you see it.

AI systems make mistakes. They can misread a study, overstate a finding, omit an important caveat, apply an animal result to humans, miss contraindications and interactions, or produce a confident answer that is simply wrong. Citations can also be wrong: a citation may be inaccurate, may not support the sentence it is attached to, or may point to a study that has since been retracted, superseded, or contradicted.

The scientific literature itself changes. An accurate summary of the evidence today can be wrong next year. We do not guarantee that any answer reflects the current state of the evidence.

• We do not warrant that any output is accurate, complete, current, reliable, or fit for any purpose.
• Citations are provided so you can read the underlying source. Read the source. A citation is not a verification, an endorsement, or a statement that the finding applies to you.
• Outputs may vary between users and between sessions for the same question. Outputs are not personalized medical guidance and are not tailored to your health status.
• If you ask the AI what to take, how much to take, or when to dose, it will not give you a personal recommendation, and any output that reads like one is not one. Do not treat it as one.
• The reconstitution calculator is a separate feature from AI answers. It is deterministic arithmetic performed on numbers you type in, not an AI output, and it is likewise not a recommendation. Section 7 governs it.
• Do not rely on any output as the basis for a health decision. Verify anything that matters with a licensed provider and with the primary literature.

7. Tracking Tools, Estimated Levels, and the Reconstitution Calculator

The tracking features in the PepSense app are a private notebook. Everything in them is self-reported by you and is not verified, validated, or reviewed by anyone. We do not know whether what you entered is accurate, whether you took what you logged, or whether the product you used contained what its label claimed.

Your log is not a medical record. It is not shared with any provider, it is not monitored, and no alert reaches a human at PepSense based on what you enter, including entries describing side effects.

The tracking features record what you tell them. They do not recommend, suggest, select, validate, verify, or approve any dose, amount, concentration, schedule, route, or protocol, and they will never tell you what to take.

The app also presents two computed displays: estimated level charts, and the reconstitution calculator. Both are described below. Neither is a measurement of anything in your body, neither is a recommendation, and neither is medical advice. Both operate entirely on numbers you supplied.

Estimated level charts are research estimates, not measurements

The app can display an estimated level curve for a compound. That curve is produced by applying a simple exponential decay model to the dose events you chose to log, using a published population half-life value stored for that compound. A population half-life is an average drawn from a study group. It is a research estimate about a population, not a fact about you.

The curve is not a plasma level. It is not a blood test, a serum concentration, a lab result, a measurement, or a reading of any kind. Nothing in the app measures anything in your body. The chart shows only what a textbook decay equation would produce from the numbers you typed in, and it would draw the same curve whether or not you actually took anything.

The estimate ignores essentially everything that determines real drug exposure in a person: your absorption, distribution, metabolism, and elimination; your body composition, age, sex, kidney and liver function; interactions with other substances, medications, and supplements; injection site, depth, and technique; the real concentration, potency, and purity of the product you used; storage, handling, and degradation; and the wide variation in the published half-life values themselves, which frequently differ several-fold between studies. Actual exposure in a given person can differ from the estimate by a very large margin in either direction. For some compounds no reliable half-life exists, and the app will say so rather than draw a curve.

Because the chart is an illustration of a formula and not a fact about your body, it must never be used as an input to a decision about what you put in your body.

• Never use an estimated level to decide whether to take a dose, how much to take, or when to take it.
• Never use it to time, stack, layer, split, skip, delay, or advance anything.
• Never use it to conclude that a compound has "cleared," "washed out," or dropped to a safe level, or that it is safe to add something else.
• Never use it to interpret a symptom, a side effect, or the absence of an effect.
• Never present it to anyone, including a clinician, as a measurement of your levels.
• If you want to know what is actually in your body, that is a question for a clinician and a laboratory, not for this app.

The reconstitution calculator: what it is

The PepSense app includes a reconstitution calculator. It is an arithmetic unit-conversion utility. You enter values that you already have in front of you: the amount of compound stated for the vial, the volume of diluent you are adding to that vial, and the amount you want to measure out. The calculator performs the arithmetic on those numbers and returns the corresponding volume, or the equivalent of that volume expressed in syringe units. That is its entire function.

The calculator is a convenience for arithmetic you could do yourself with a pencil, a piece of paper, and the same three numbers. Performing that arithmetic on a phone does not make it advice, guidance, a prescription, a clinical judgment, or a professional service, and you should not treat it as any of those things.

The reconstitution calculator: what it does not do

The calculator operates only on the numbers you supply. It does not recommend, suggest, select, validate, verify, or approve any amount. It does not generate protocols, titration schedules, dosing regimens, frequency guidance, or timing guidance. It does not tell you what to take, how much to take, how often to take it, or whether to take anything at all.

The calculator does not know and does not evaluate whether any amount is appropriate for any person. It has no knowledge of your health, your history, your medications, your conditions, your weight, your kidney or liver function, your tolerance, or your goals, and it does not consider any of them. It does not know what compound is actually in your vial, what its true concentration, potency, or purity is, whether the vial label is accurate, what diluent you actually used, what syringe you are actually holding, or how that syringe is graduated.

A number displayed by the calculator is a conversion of the numbers you typed in. It is not a recommendation that you use that number, not confirmation that the number is safe or correct, and not permission or approval to proceed.

• The calculator converts numbers you enter. It does not choose them for you.
• It does not tell you how much to take, how often to take it, or whether to take anything at all.
• It does not verify your vial, your compound, your diluent, your syringe, or your labeling.
• It does not check whether an amount is safe, appropriate, effective, or lawful for you.
• It does not create, review, adjust, or approve any protocol or schedule.
• It does not know anything about you and does not account for anything about you.

Wrong inputs produce wrong outputs, and no accuracy is warranted

The output is only as reliable as the input. If you mistype a value, misread a vial label, confuse units, misidentify a syringe or its graduations, or enter a number in the wrong field, the result will be wrong, and it will be displayed with exactly the same confidence as a correct result. The calculator has no way to detect an implausible, mistaken, or dangerous input, and it will not warn you about one.

Labels on products obtained outside a regulated pharmacy supply chain are frequently inaccurate. Such products may be mislabeled, underfilled, overfilled, degraded, or contaminated. If the amount stated on your vial is not the amount actually in your vial, every figure derived from it will be wrong, and PepSense has no ability to know or detect that.

We do not warrant that the calculator or any figure it produces is accurate, complete, reliable, error-free, or fit for any purpose. Sections 15 and 16 apply in full to the calculator and to its output.

Your responsibility, verification, and assumption of risk

You are solely responsible for every value you enter into the calculator, for checking the result, and for anything you do with it. Preparing, measuring, and administering anything is your act alone, performed outside the Service and without our involvement, knowledge, supervision, or control.

You must independently verify every figure with a qualified professional, such as your prescribing clinician or a pharmacist, before relying on it for any purpose. Do not use the calculator as the sole basis for preparing, measuring, or administering anything. Check the arithmetic yourself, check it against your vial and your syringe, and check it with a professional.

By using the calculator you knowingly and voluntarily assume all risk arising from its use, including the risk of a calculation, measuring, preparation, or administration error and any injury, illness, disability, adverse reaction, drug interaction, financial loss, or legal consequence that follows from one. You agree that relying on calculator output without independent verification by a qualified professional is unreasonable and is at your sole risk. Section 14 (Assumption of Risk and No Reliance) and Section 16 (Limitation of Liability) apply to the calculator and to your reliance on anything it displays.

PepSense is not a pharmacy, a compounding pharmacy, a manufacturer, a compounder, a distributor, or a prescriber. We do not supply any compound, diluent, vial, syringe, or other material, we do not inspect or verify anything you have obtained, and we have no role in what you prepare or administer.

• Verify every figure with a qualified professional before relying on it.
• Never treat a calculator result as a recommendation, a prescription, a validation, or approval to proceed.
• Never present a calculator result to anyone as clinician-reviewed, verified, or professionally prepared.
• Never use the calculator to prepare, measure, or produce instructions for another person.
• If you are unsure about any value, stop and ask a licensed clinician or a pharmacist rather than proceeding.

Reminders

If you enable them, the app can schedule local reminders on your device. Reminders are a convenience feature. They can fail to fire, fire late, fire twice, or be suppressed by your device settings, operating system, focus modes, battery mode, storage state, or a device restart. A reminder is not a clinical alert and is not evidence that anything should be taken. Do not rely on reminders for anything that matters. We are not responsible for a missed, duplicated, or mistimed reminder or for anything that follows from one.

8. Plans, Subscriptions, and Billing

PepSense offers a Free tier and a paid tier called Pro. Current pricing is shown on the purchase screen in the app before you buy, and on pepsense.ai. Pro may be offered on a monthly or an annual basis, and the plans, the features included in them, and their prices may change with notice as described below. We do not state prices in these Terms, because they vary by plan and region and can change; the purchase screen is the authoritative source at the moment you buy.

Some releases of the app may be distributed during a launch period with no paid tier and no purchase screen. If your build does not offer a paid plan, the billing terms in this section do not apply to you unless and until you subscribe.

What you get for the price

Before you subscribe, the purchase screen tells you what Pro includes for the period you are buying, the length of that period, the price, and any introductory or trial offer. The plan comparison above describes the tiers in general terms; the purchase screen governs the specific offer presented to you.

The Free tier is limited by a daily question cap, which is shown in the app. Pro raises that cap and unlocks the additional features listed on the purchase screen. We may change what each tier includes. If a change materially reduces what you are already paying for, we will tell you before it takes effect, and you may cancel.

Subscriptions purchased in the iOS app (Apple auto-renewable subscription)

If you subscribe inside the PepSense iOS app, the purchase is an auto-renewable subscription processed by Apple. Apple, not PepSense, bills you and holds the payment relationship. The following terms apply.

• Payment is charged to your Apple Account at confirmation of purchase.
• The subscription automatically renews for the same period unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your Apple Account is charged for renewal within 24 hours prior to the end of the current period, at the then-current price for your plan.
• You can manage your subscription and turn off auto-renew at any time after purchase in your Apple ID Account Settings. PepSense cannot cancel, pause, downgrade, or modify an Apple subscription for you.
• Turning off auto-renew stops future renewals. It does not end the current period, and your access continues until that period ends.
• Refunds for purchases made through Apple are requested from and decided by Apple, under Apple's policies and the Apple Media Services Terms and Conditions. PepSense cannot issue, promise, or override a refund for an Apple purchase.
• If a free trial or introductory offer is made available, the purchase screen states its length and the price charged when it ends. The trial converts to a paid subscription unless auto-renew is turned off at least 24 hours before the trial ends. Any unused portion of a free trial period is forfeited when you purchase a subscription to that content, where applicable.
• Deleting your PepSense account does not cancel an Apple subscription. Turn off auto-renew in your Apple ID Account Settings, or Apple will continue to bill you.
• Pro purchased on iOS is available on the Apple devices signed in to the same Apple Account. Use "Restore Purchases" in the app if an existing subscription is not recognized.

Price changes, taxes, and failed payments

We may change subscription prices. For an existing subscription, a price change applies only to periods beginning after notice is given. Where Apple's rules require it, Apple will notify you and ask for your consent before a price increase takes effect, and the subscription will not renew at the higher price without that consent. If you do not want a new price, turn off auto-renew before the change takes effect.

Prices shown at purchase may be exclusive of taxes. You are responsible for any sales, use, VAT, GST, or similar taxes, which may be added at checkout or collected by Apple.

If a payment fails, Apple may retry it under its own rules, and we may suspend or downgrade Pro access until payment succeeds. If your subscription lapses, your logged data is not deleted, but features that require Pro stop working.

9. Acceptable Use

Use PepSense for your own research and your own private tracking. The following are prohibited, and doing any of them is a material breach of these Terms.

• Using the Service to diagnose, treat, monitor, or manage the health of any other person, or to provide medical, clinical, nursing, pharmacy, coaching, or similar services to anyone.
• Using the reconstitution calculator to prepare, measure, or administer anything for another person, or to produce preparation, measuring, or administration instructions for another person.

• Impersonating anyone, or misrepresenting your affiliation with PepSense.
• Using the Service in violation of any applicable law, including export control and sanctions laws.

10. Your Content

"Your Content" means everything you put into the Service: the questions you ask, the notes and symptoms you type, the compounds, doses, weights, side effects, and goal metrics you log, the values you enter into the reconstitution calculator, the progress photos you upload, and anything else you submit.

You own Your Content. We do not claim ownership of it, and using PepSense does not transfer any rights in it to us.

You grant us a limited, worldwide, non-exclusive, royalty-free license to host, store, back up, transmit, process, reproduce, and display Your Content, and to use our service providers to do the same, solely for the purposes of operating, securing, and providing the Service to you, and for other purposes you separately consent to. This license exists so we can run the product. It ends when you delete the content or your account, except for copies that remain in routine backups until those backups cycle out on their normal schedule as described in the Privacy Policy, and except where we must retain something to comply with law.

• We do not sell Your Content, and we do not use your health data for advertising or marketing.
• We do not use Your Content to train large language models. Questions you ask are transmitted to our AI providers under contract for the purpose of generating an answer for you. The Privacy Policy names those providers and describes what they receive.
• You are responsible for Your Content, including that you have the right to submit it and that it does not contain another person's personal or health information without their permission.
• We do not review, verify, or monitor Your Content, and we have no obligation to do so. We may remove content that violates these Terms or the law.
• Your Content is private to your account. It is not published, shared with other users, or made public by the Service.

11. Our Intellectual Property, and Your Feedback

The Service, including its software, design, interfaces, text, research summaries, compiled corpus, databases, and the PepSense name and logo, is owned by PepSense, Inc. or its licensors and is protected by intellectual property laws. Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to access and use the Service for your own research and personal tracking. All rights we do not expressly grant are reserved.

You may keep copies of individual answers for your own reference and share an occasional answer for personal, non-commercial purposes with attribution to PepSense. You may not use our marks without our written permission, and you may not remove or obscure any notice or disclaimer attached to output, including any disclaimer attached to calculator output.

The underlying scientific literature belongs to its authors and publishers. Citations link to sources we do not own or control, and access to a source is governed by that publisher's terms.

If you send us feedback, suggestions, feature requests, or ideas, you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use them for any purpose without restriction, attribution, or compensation. Do not send us feedback you consider confidential or that you are not free to share.

12. Third-Party Services, Links, and Vendor Information

The Service depends on third-party providers, including our hosting, database, authentication, AI, and app store providers. Those providers are described in the Privacy Policy. Their availability, performance, and policies are outside our control.

The Service may contain links to third-party websites, including publishers, journals, and clinical trial registries. We do not control those sites, we do not endorse them, and we are not responsible for their content, accuracy, availability, or privacy practices. Your use of a third-party site is governed by that site's terms.

PepSense does not list, rank, review, recommend, or link to vendors of peptides or related compounds. If a vendor name, product, price, or claim ever appears anywhere in the Service, including inside a research citation or in text you yourself entered, it is not an endorsement, not a verification, and not a representation by us that the vendor or product is legitimate, legal, safe, pure, accurately labeled, or suitable for any use. We have no relationship with any such vendor and receive no compensation from any of them.

You must also comply with the terms of any third party whose services you use to access PepSense, including your mobile carrier's data plan terms and Apple's terms for the App Store.

13. Privacy and Your Data

How we handle your information is described in the Privacy Policy at pepsense.ai/privacy and, for consumer health data, in the separate Consumer Health Data Privacy Policy at pepsense.ai/consumer-health-data-privacy. Both are part of your agreement with us and you should read them.

Two points belong here. First, PepSense is not a covered entity or a business associate under HIPAA, so HIPAA does not apply to the information you enter. That does not mean your information is unprotected: state consumer health data laws apply to us directly, and we treat your protocol data as sensitive. Second, consent to collect and use your health data is obtained separately from these Terms, through in-app consent screens, and you can withdraw it as described in the Privacy Policy.

We describe our security practices in the Privacy Policy. We commit to using reasonable administrative, technical, and physical safeguards appropriate to the sensitivity of the data. No service can promise perfect security, and we do not. Where data is removed at your request, live copies are removed promptly and copies held in routine backups are removed as those backups cycle out on their normal schedule; we do not promise instantaneous erasure from every system.

14. Assumption of Risk and No Reliance

You acknowledge and agree that decisions about whether to obtain, possess, prepare, measure, or use any compound are yours alone, made independently of PepSense, and that you assume all risk arising from those decisions, including the risk of injury, illness, disability, adverse reaction, drug interaction, financial loss, and legal consequence.

You agree that you will not rely on the Service, on any AI-generated answer, on any citation, on any estimated level chart, on any output of the reconstitution calculator, on any logged entry, on any reminder, or on any other feature as the basis for a medical, health, legal, or purchasing decision, and that any such reliance is unreasonable and is at your sole risk.

You specifically acknowledge that the reconstitution calculator performs arithmetic only on values you supply, that it does not recommend, validate, verify, or approve any amount, that it does not evaluate whether any amount is appropriate for any person, and that its output will be wrong if your inputs are wrong. You are solely responsible for the values you enter and for everything you do with the result. You agree that it is your responsibility to verify every figure independently with a qualified professional before relying on it, and you knowingly assume all risk of calculation, measuring, preparation, and administration error, including error arising from your reliance on calculator output, whether or not you verified it.

To the fullest extent permitted by law, you release PepSense, Inc. and its officers, directors, employees, contractors, and agents from claims, demands, and damages arising out of or connected to your acquisition, preparation, or use of any compound, your use of or reliance on the reconstitution calculator or its output, or any outcome you attribute to information obtained through the Service.

This section applies to all users of the Service, including users of the iOS app, and is in addition to the disclaimers in the EULA.

15. Disclaimer of Warranties

The Service is provided "as is" and "as available," with all faults and without warranty of any kind. To the fullest extent permitted by law, PepSense and its suppliers disclaim all warranties, express, implied, statutory, and otherwise, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, and any warranties arising from course of dealing or usage of trade.

Without limiting the above, we do not warrant that the Service or its content will be accurate, complete, reliable, current, safe, or error-free, that it will meet your requirements, that it will be uninterrupted or secure, that defects will be corrected, or that any result obtained from it is correct or suitable for any purpose. This applies to every figure produced by the reconstitution calculator and to every estimated level chart. We make no warranty of accuracy and no warranty of fitness for any purpose as to calculator output, which is arithmetic performed on values you chose and can be no more reliable than those values. No advice or information, whether oral or written, obtained from PepSense or through the Service creates any warranty not expressly stated here.

Some jurisdictions do not allow the exclusion of certain warranties. In those jurisdictions, the exclusions above apply only to the extent permitted, and you may have additional rights.

16. Limitation of Liability

To the fullest extent permitted by law, PepSense, Inc. and its officers, directors, employees, contractors, agents, suppliers, and licensors will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, loss of goodwill, business interruption, or the cost of substitute services, arising out of or relating to these Terms or the Service, whether based in contract, tort, negligence, strict liability, statute, or any other theory, and whether or not we were advised of the possibility of those damages.

For the avoidance of doubt, the exclusions and limits in this section apply to any claim arising out of or relating to your use of, or your reliance on, the reconstitution calculator or any figure it produces, including any calculation, measuring, preparation, or administration error and any injury or loss attributed to one, as well as to estimated level charts, reminders, AI-generated answers, citations, logged entries, and every other feature of the Service.

To the fullest extent permitted by law, our total aggregate liability for all claims arising out of or relating to these Terms or the Service is limited to the greater of (a) the amount you paid us for the Service in the twelve months immediately before the event giving rise to the claim, or (b) one hundred U.S. dollars ($100).

These limits are an essential part of the bargain between us and apply even if a limited remedy fails of its essential purpose.

• Nothing in these Terms excludes or limits liability for fraud or fraudulent misrepresentation, for gross negligence or willful misconduct, for death or personal injury caused by our negligence, or for any other liability that cannot lawfully be excluded or limited.
• Nothing in these Terms limits our liability to you beyond what applicable law permits. Any provision that would do so is limited to the maximum extent the law allows rather than applied as written.
• Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages. In those jurisdictions, the limitations above apply only to the extent permitted.

17. Indemnification

You agree to indemnify, defend, and hold harmless PepSense, Inc. and its officers, directors, employees, contractors, agents, suppliers, and licensors from and against any claims, demands, actions, liabilities, damages, losses, judgments, settlements, costs, and expenses, including reasonable attorneys' fees, arising out of or relating to your use or misuse of the Service, Your Content, your breach of these Terms or of any law, your acquisition, possession, preparation, or use of any compound, your use of or reliance on the reconstitution calculator or its output, any decision you make based on information obtained through the Service, or your infringement of any third party's rights.

We may assume the exclusive defense and control of any matter subject to indemnification by you, at your expense, and you agree to cooperate with that defense. You will not settle any matter that imposes any obligation or admission on us without our prior written consent. This obligation survives termination of your account and of these Terms.

This section does not apply to the extent a claim arises from our own fraud, gross negligence, or willful misconduct, and it does not apply where applicable consumer law prohibits it.

18. Suspension, Termination, and Account Deletion

You can stop using the Service at any time. You can delete your account yourself from Settings in the PepSense app. Deleting your account removes the account record and the personal data associated with it, including your compounds, dose events, weight entries, side effects, goal metrics, progress photos, and chat history, as described in the Privacy Policy, subject to the narrow retention exceptions stated there. Live copies are removed promptly, and copies held in routine backups are removed as those backups cycle out on their normal schedule.

We may suspend or terminate your access, in whole or in part, with or without notice, if you breach these Terms, if we reasonably believe your use creates legal risk or a risk of harm to you or others, if required by law, or if we discontinue the Service. Where practical and lawful, we will give you notice and an opportunity to export your data.

Terminating your account does not by itself refund a subscription. Subscriptions purchased through Apple are billed and refunded by Apple, and any refund request for such a purchase is made to and decided by Apple under Apple's policies. PepSense cannot issue a refund for an Apple purchase and does not promise one.

On termination, your license to use the Service ends immediately. Provisions that by their nature should survive do survive, including Sections 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 19, 20, 22, and 23.

19. Dispute Resolution, Arbitration, and Class Action Waiver

This section affects your legal rights, including your right to sue in court and to participate in a class action. Please read it. It is written to be even-handed: it applies equally to you and to us, it lets you opt out at no cost, it preserves small claims court, and it preserves your right to go to a government agency.

This Section 19 is the single authoritative dispute resolution provision for PepSense. It governs disputes for every user of the Service, including users of the iOS app, and it controls over any different or inconsistent dispute resolution, venue, or jurisdiction provision in the EULA or in any other PepSense document. Any other PepSense document that addresses dispute resolution does so only by cross-reference to this section.

"Dispute" means any claim or controversy between you and PepSense arising out of or relating to these Terms, the EULA, the Service, or the app, whether based in contract, tort, statute, fraud, or any other theory.

Step 1: Talk to us first

Before starting an arbitration or a lawsuit, you agree to try to resolve the Dispute informally. Send a written notice to support@pepsense.ai describing the Dispute, what you want, and how to reach you. We will do the same for a Dispute we have with you, using the email address on your account. Both sides agree to negotiate in good faith for 60 days after the notice is received, and either side may request a short telephone or video call during that period.

This step applies equally to both of us and is a condition to starting arbitration. Any applicable statute of limitations is tolled for those 60 days. Many disputes are resolved here. If yours is not, either side may proceed.

Step 2: Binding individual arbitration

If the Dispute is not resolved informally, it will be settled by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, as modified by these Terms. The AAA rules are available at adr.org. The Federal Arbitration Act governs the interpretation and enforcement of this section. The arbitrator, not a court, decides issues about the interpretation, scope, applicability, and enforceability of this arbitration agreement, except that a court decides the enforceability of the class action waiver below.

Arbitration is less formal than court. There is no judge or jury, review of the award is limited, and discovery is more limited than in court, but an arbitrator can award the same individual relief a court could, including damages, statutory damages, injunctive relief for you individually, and attorneys' fees where a statute or the AAA rules provide for them. The arbitrator must apply the same law a court would and must issue a written decision explaining the essential findings.

The arbitration will be conducted by a single arbitrator. Unless you and we agree otherwise, it will proceed on documents only or by telephone or video, or, if an in-person hearing is required, in the county where you live or another location we both agree to. You will never be required to travel outside your home county for a hearing.

We will pay the AAA filing, administration, and arbitrator fees for any claim seeking $10,000 or less, unless the arbitrator finds the claim frivolous or brought for an improper purpose. Otherwise, fees are allocated under the AAA Consumer Arbitration Rules, which cap consumer filing fees. If the AAA fee schedule would make arbitration prohibitively expensive for you compared with going to court, we will pay the amount the arbitrator determines is necessary to prevent that.

Class action and jury trial waiver

You and PepSense each agree that Disputes will be brought only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, coordinated, or representative proceeding. The arbitrator may not consolidate the claims of more than one person and may not preside over any form of class or representative proceeding. This waiver applies to both of us equally.

YOU AND PEPSENSE EACH KNOWINGLY AND VOLUNTARILY WAIVE THE RIGHT TO A TRIAL BY JURY for any Dispute subject to this section. In arbitration there is no jury. If for any reason a Dispute proceeds in court rather than arbitration, both of us still waive any right to a jury trial, to the fullest extent permitted by law.

If a court decides that the class action waiver is unenforceable as to a particular claim or request for relief, then that claim or request for relief, and only that one, will be severed from arbitration and brought in the courts identified in Section 20. Everything else stays in arbitration. If any other part of this Section 19 is found unenforceable, the rest remains in effect.

Exceptions and things this section does not take away

Either of us may bring an individual claim in small claims court, in a court with jurisdiction, if the claim qualifies under that court's rules. Filing in small claims court is not a breach of this section, and either of us may do so instead of arbitrating.

Either of us may also seek injunctive or other equitable relief in court to protect intellectual property rights or to stop unauthorized access to or misuse of the Service.

Nothing in this section prevents you from reporting a concern to, filing a complaint with, or participating in an action by any federal, state, or local government agency, including a consumer protection agency or attorney general, and nothing here waives any right you have to relief obtained through such an agency.

Nothing in this section shortens any statutory limitations period. Claims must be brought within the period allowed by applicable law, including any longer period provided by consumer protection, consumer health data, privacy, or personal injury statutes.

Nothing in this section waives any right that cannot lawfully be waived, and nothing in it deprives you of the protection of mandatory consumer protection laws of the place where you live.

20. Governing Law and Venue

These Terms and any Dispute are governed by the laws of the State of Delaware, without regard to its conflict of laws rules, and by applicable U.S. federal law, including the Federal Arbitration Act.

For any Dispute not subject to arbitration, including because you opted out under Section 19 or because a claim was severed, you and PepSense consent to the jurisdiction of the state and federal courts located in Delaware.

Nothing in this section deprives you of the protection of mandatory consumer protection laws of the state or country where you live that cannot be waived by agreement, or of the right to bring a claim in a forum that those laws require or permit. If the law of your state of residence gives you the right to bring a claim in the courts of that state, you may do so, and we will not contest venue on that basis. If you are a consumer in the European Union or the United Kingdom and the Service is available to you, you may also bring proceedings in the courts of your country of residence.

This section applies to all users of the Service, including users of the iOS app, and controls over any different governing law or venue provision in the EULA, subject always to Section 19.

21. Changes to These Terms and to the Service

We may update these Terms. When we do, we will change the effective date at the top and post the updated version at pepsense.ai. If a change is material, we will give you reasonable advance notice by email or in the app before it takes effect. A material change to Section 19 will not apply retroactively to a Dispute for which notice under Section 19, Step 1 has already been given.

Continuing to use the Service after an update takes effect means you accept the updated Terms. If you do not accept them, stop using the Service and delete your account. A change to these Terms is not a substitute for the separate consent we obtain for health data processing, and we will ask for fresh consent where the law requires it.

We may also change, improve, limit, or discontinue features of the Service. We will not remove a material feature you are actively paying for without notice. If we discontinue a paid feature during a period you have already paid for through Apple, you may request a refund from Apple, which decides refund requests under its own policies. We are not liable to you for modifying or discontinuing any part of the Service, subject to Section 16.

22. Additional Terms for the iOS App (Apple)

This section applies if you obtained the PepSense app from the Apple App Store. It supplements the End User License Agreement (EULA) at pepsense.ai/eula, which governs your license to the app and contains the full set of terms Apple requires. Read the EULA together with these Terms; both apply to you, and the EULA does not replace or supersede these Terms.

Where the EULA and these Terms address the same subject, the order of precedence in Section 1 applies. In particular, Section 19 (Dispute Resolution) and Section 20 (Governing Law and Venue) of these Terms govern for all users, including iOS users, and control over any inconsistent provision in the EULA. Section 7 (Tracking Tools, Estimated Levels, and the Reconstitution Calculator) and Section 14 (Assumption of Risk and No Reliance) also apply to iOS users in addition to the EULA's disclaimers.

You and we acknowledge and agree to the following.

• These Terms and the EULA are concluded between you and PepSense, Inc. only, and not with Apple. PepSense, not Apple, is solely responsible for the PepSense app and its content, including the reconstitution calculator. These Terms are not inconsistent with the Apple Media Services Terms and Conditions.
• Your license to the app is a non-transferable license to use it on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the app may be accessed and used by other accounts associated with you through Family Sharing, volume purchasing, or Legacy Contacts.
• PepSense is solely responsible for providing maintenance and support for the app. Apple has no obligation whatsoever to furnish any maintenance or support services for it.
• PepSense is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the app to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty are PepSense's sole responsibility.
• PepSense, not Apple, is responsible for addressing any claim by you or any third party relating to the app or your possession or use of it, including product liability claims, any claim that the app fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
• If a third party claims that the app or your possession and use of it infringes that third party's intellectual property rights, PepSense, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of that claim.
• You represent and warrant that you are not located in a region that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" region, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• You must comply with applicable third-party terms of agreement when using the app, including your wireless carrier's data service terms.
• Subscriptions purchased in the app are auto-renewable subscriptions billed by Apple, on the terms set out in Section 8. Apple decides refund requests for those purchases under Apple's policies.
• Apple and Apple's subsidiaries are third party beneficiaries of these Terms and of the EULA, and upon your acceptance, Apple has the right, and is deemed to have accepted the right, to enforce them against you as a third party beneficiary.
• Questions, complaints, and claims about the app should be directed to PepSense using the contact information at the end of this document, not to Apple.

23. General Terms

These Terms, together with the Privacy Policy, the Consumer Health Data Privacy Policy, the EULA, any messaging terms you separately accept, and any plan-specific terms presented at purchase, are the entire agreement between you and PepSense about the Service, and replace any prior agreement or understanding on that subject. The EULA applies in addition to these Terms and does not supersede them; where they overlap, the order of precedence in Section 1 applies.

If a provision of these Terms is found unenforceable, it will be limited or removed to the minimum extent necessary and the rest remains in full force. Our failure to enforce a provision is not a waiver of it, and no waiver is effective unless in writing.

You may not assign or transfer these Terms or your account without our written consent. We may assign these Terms to an affiliate or in connection with a merger, acquisition, reorganization, or sale of assets, on notice to you. These Terms bind and benefit the parties and their permitted successors and assigns.

We will send legal notices to the email address on your account, and they are effective when sent. Send legal notices to us at support@pepsense.ai and, where a physical address is required, to the address in the contact block below.

Neither party is liable for a delay or failure to perform caused by events beyond its reasonable control, including natural disasters, acts of government, labor disputes, network or provider outages, and failures of third-party services on which the Service depends. This does not excuse payment obligations.

You may not use or export the Service except as authorized by U.S. law and the laws of the jurisdiction where the Service was obtained. Nothing in these Terms creates a partnership, joint venture, employment, agency, or fiduciary relationship. Headings are for convenience only. These Terms are drafted in English, and the English version controls in the event of a conflict with any translation.
