Terms of Service

1. Not medical advice (please read first)

SelfAssay is a personal-research and decision-support tool. It is not a medical device, and it does not diagnose, treat, cure, or prevent any disease. Content, grades, summaries, interaction checks, lab interpretations, experiment verdicts, and assistant answers are for informational purposes only and are not medical, pharmacological, or professional advice.

Using the Service does not create a doctor-patient, pharmacist-patient, or other professional relationship. Always seek the advice of a licensed clinician or pharmacist before starting, stopping, or changing any supplement, peptide, medication, or routine, especially if you are pregnant or breastfeeding, have a medical condition, or take prescription drugs. Never disregard professional medical advice or delay seeking it because of something you read on the Service. If you think you may have a medical emergency, call your doctor or emergency services immediately. You are solely responsible for your own decisions and outcomes.

We are not a healthcare provider, and SelfAssay is not a covered entity or business associate under HIPAA.

2. Eligibility

You must be at least 18 years old and able to form a binding contract to use the Service. By using it, you represent that you meet these requirements and that your use complies with all laws that apply to you.

3. What the Service does

The Service helps you research supplements, peptides, and other compounds; view community Benefit, linked research context, and selected observed adverse-event signals; check interactions; compose and track protocols; decode lab reports against your stack; and run your own n-of-1 experiments. Factual claims from our assistant are grounded in source provenance, and the assistant is designed to decline rather than guess when evidence is thin. We give you the evidence honestly; the decisions are yours.

4. AI-generated content

Parts of the Service use automated and AI systems. Their output may be incomplete, out of date, or incorrect, and may not fit your individual situation. Grades and summaries are derived from third-party research and real-world reports and are not guarantees of efficacy or safety. Always verify important information independently and with a qualified professional. You must not rely on the Service as the sole basis for any health, medical, or purchasing decision.

5. Your account

You are responsible for keeping your credentials secure and for all activity under your account. Notify us promptly at hi@selfassay.com if you suspect unauthorized access. Keep your account information accurate. We may refuse, suspend, or terminate accounts that violate these Terms or abuse the Service.

You may issue credentials that let another application — for example an AI assistant — act for you through our connector. Anything done with a credential you issued counts as activity under your account, and you are responsible for it — except for use you did not authorise, where you tell us as soon as you know or suspect it, and except where the unauthorised use was caused by our own failure. Grant only the permissions you intend, revoke a credential promptly if you lose access to the application or no longer want it connected, and tell us if you think one has been misused. We may revoke a credential, or suspend a connecting application, immediately and without notice, where we believe it is being abused, is insecure, or is being used in breach of these Terms, and we will tell you when we reasonably can.

A credential you issue is scoped and revocable, and we never accept your ordinary sign-in session as one. Do not hand your SelfAssay password or a sign-in link to a third party; issue a credential instead, and remove it from Settings → Connected assistants when you are done.

6. Your content (the Vault)

You own the content you add to your Vault. You grant us a limited, worldwide, non-exclusive license to host, store, encrypt, process, and display that content solely to operate and provide the Service to you. We do not claim ownership of your content, and we do not sell it. If you separately and explicitly opt in, de-identified, aggregated data may be contributed to our community and measured-outcomes datasets as described in the Privacy Policy. You are responsible for the content you provide and confirm you have the right to provide it.

7. Acceptable use

You agree not to:

• use the Service to harm yourself or others, or for any unlawful purpose;
• provide professional, medical, or pharmacological advice to third parties using the Service in violation of applicable law or your own licensure;
• scrape, crawl, bulk-export, reverse engineer, or attempt to extract our underlying data, models, or knowledge graph, or circumvent the provenance gate, rate limits, paywalls, or security controls — using an official SelfAssay API, MCP endpoint, or connector credential within its published limits and in accordance with Section 12 is not a breach of this bullet, but bulk extraction, mirroring, or rebuilding our corpus is a breach however it is done;
• resell, sublicense, or commercially exploit the Service except as expressly permitted (see Practitioner accounts);
• upload malware, interfere with the Service, or infringe others’ rights;
• misrepresent your identity or use automated means to create accounts — an application you have expressly authorised to act for you through our connector is not a misrepresentation.

We may rate-limit, suspend, or block activity that appears automated, abusive, or non-compliant.

8. Practitioner accounts

If you use the Service in a professional capacity (e.g. a coach or clinician preparing protocols or exports for clients), you are solely responsible for: your own professional, licensing, and legal obligations; obtaining any consents required to enter client information; the advice you give your clients; and ensuring your use complies with all laws that apply to your practice. SelfAssay is a tool you use; we are not a party to, and are not responsible for, your relationship with your clients. Client records are excluded from every permission a connected AI assistant can be granted: connecting an assistant does not give it access to information you hold about your clients. That exclusion follows where the information is stored, so keep client information in your client records — anything you put in your own stack, intake log, or medications is treated as your own for this purpose, even if it relates to a client. If that ever changes, we will ask you separately first.

9. Plans, billing, and cancellation

The Service offers a free tier with limited usage of certain features (some features are available only on a paid plan) and paid subscriptions. Paid plans are billed in advance on a recurring basis (monthly or annual) through our payment processor, Dodo Payments, under their terms. Subscriptions renew automatically for the same term until cancelled. You can cancel any time from your account; cancellation stops future renewals and takes effect at the end of the current billing period, and you retain access until then.

Prices are shown at checkout and may change on a prospective basis with notice. You are responsible for applicable taxes.

Refunds

Except where required by law, payments are non-refundable: cancelling stops future renewals and you keep access until the end of the paid period. If you are a consumer in the EU or UK, you have a statutory 14-day right of withdrawal from your first purchase; by starting to use the paid Service immediately you request immediate performance, and if you withdraw within that window we may deduct a proportionate amount for the service already provided. Renewal payments are not refundable except where the law requires. We may issue refunds at our sole discretion; a refunded subscription ends immediately. Accounts that abuse refunds (for example, repeated subscribe-use-refund cycles) may be refused service or terminated under Section 16.

10. Intellectual property

The Service, including its software, design, grades, knowledge graph, and other materials (excluding your Vault content and third-party materials), is owned by us or our licensors and protected by intellectual-property laws. We grant you a limited, revocable, non-transferable license to use the Service for your personal use (or, for Practitioner accounts, your permitted professional use) in accordance with these Terms. If you send us feedback or suggestions, you grant us a perpetual, royalty-free license to use them without obligation to you.

11. Third-party content and services

The Service surfaces information derived from third-party research, literature, real-world reports, and data sources, and relies on third-party providers (e.g. hosting, AI, payments). We do not endorse, and are not responsible for, third-party content, products, or services, and your use of them may be subject to their own terms.

12. API, MCP and connector access

We make available a public, read-only interface — an API and an MCP endpoint — that returns summary-level information about compounds, the same material we publish on selfassay.com. It requires no account and gives access to no account: used on its own it cannot read a Vault or any other member content. It is part of the Service: by calling it, registering an application with us, or accepting a credential issued through it, you agree to these Terms, whether or not you have a SelfAssay account.

Separately, a member may connect an application to their own account by issuing a scoped credential, which lets that application read the permitted parts of their account. A connection is read-only: it cannot create, change, or delete anything the member has recorded — not their stack, their dose log, or their notes. Opening a full dossier through a connection does count against a free plan’s dossier allowance, exactly as opening one on the website does. What may be read is described in our Privacy Policy. Connecting an application to your account opens to all members thirty days after we notify members by email and in the app; until then it is limited to accounts we enable ourselves, for our own testing and for review by the platforms that list us. A connected application acts as the member who connected it (Section 5), and paid features reached through a connection are personal to that member: an entitlement, allowance, or quota is not transferable, poolable, or resellable, and a credential must not be shared with anyone else or used to serve other people.

Access is provided as is, without any commitment to availability, and we may rate-limit, change, suspend, or withdraw it, in whole or for any caller, at any time and without notice. Published limits are a ceiling, not an entitlement.

If you use it, you agree to:

• use it to answer genuine requests, and not to enumerate, mirror, or reconstruct our corpus, knowledge graph, or grades, whether in one run or gradually;
• stay within the published rate limits, honour a rate-limit response, and not evade limits by rotating addresses, keys, credentials, or identities;
• attribute results to SelfAssay, and keep the disclaimer and the linked source with any result you display, quote, or pass on;
• cache a result from the public interface only briefly — to serve the request you obtained it for, and to avoid repeating an identical call — and refresh or delete it within 30 days; do not keep a standing local copy of our content; this 30-day window does not apply to anything you receive through a member’s connection, which is governed by the retention obligation below;
• not resell, sublicense, or meter access to our data as a product in itself, and not charge anyone for access to the interface; building a commercial product that calls it is allowed if you comply with this section;
• not use our name, logo, or brand except to attribute a result, not name your application after ours, and not state or imply that SelfAssay endorses, certifies, partners with, or has reviewed your application — registering an application with us is not a review of it;
• not present our summaries as your own clinical or professional assessment, and not use them to give medical advice, dosing, or treatment instructions to anyone;
• not use it to train, fine-tune, distil, or evaluate a model on our data, or to build a competing dataset or product;
• where you operate an application a member has connected to their account: act only for the member who connected you and only to answer what they asked, and use what you receive for nothing else — no advertising, no profiling, no building a picture of them across services, no sale or disclosure to anyone but a provider acting for you under equivalent obligations, and no training, fine-tuning, distilling, or evaluating any model on it unless that member has given you their own consent to that;
• protect what you receive with security appropriate to health information, keep it only as long as you need it to answer the member, and delete it when the member revokes the connection or asks you to, unless the law requires you to keep it;
• never attempt to work out, infer, or reconstruct which medications a member takes: an interaction check tells you only that a flag involves a medication on file, and probing, enumerating, or differencing results to discover which one is a breach of these Terms;
• honour a revocation immediately — stop using the credential, and do not continue to rely on, or re-present, what you received as though the connection were still live;
• never present a member’s own recorded entries back to them as a finding or recommendation of ours.

These are conditions of access to the Service. A member who connects an application decides to do so, and the operator of that application decides for itself what it then does with what it receives: it does not act on our behalf, it is not our agent or our processor, we are not joint controllers with it, and we are not responsible for its compliance with these conditions or with the law that applies to it.

Results are summary-level, derived from third-party research and real-world reports, and are subject to Sections 1 and 4: they are decision support, not medical advice, and not a determination of efficacy or safety. If you make our results available to other people, through an assistant or otherwise, you are responsible for how you present them, including for not describing the absence of a reported signal as a finding of safety.

No credential we issue today confers the ability to create, change, or delete a member’s own records, and no such permission can be granted. If we later add a permission that writes to a member’s record, it will be offered as a separate permission a member grants on its own, and these Terms and our Privacy Policy will say so before it is available.

13. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR THAT ANY CONTENT, GRADE, OR INSIGHT WILL BE ACCURATE OR SUITABLE FOR YOUR SITUATION. Some jurisdictions do not allow certain warranty exclusions, so parts of this section may not apply to you.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SELFASSAY AND ITS OPERATORS, OFFICERS, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST DATA, OR PERSONAL INJURY OR HEALTH OUTCOMES, ARISING FROM OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICE. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD $100. Nothing in these Terms limits liability that cannot be limited by law (e.g. for death or personal injury caused by negligence, fraud, or your non-waivable statutory rights).

15. Indemnification

To the extent permitted by law, you agree to indemnify and hold harmless SelfAssay and its operators from claims, damages, and expenses (including reasonable legal fees) arising from your content, your use of the Service, your violation of these Terms or applicable law, or, for Practitioner accounts, your interactions with your clients, or, if you use our API, MCP endpoint, or a connection to a member’s account, claims brought by a person you served using it.

16. Suspension and termination

You may stop using the Service and delete your account at any time from Settings. We may suspend or terminate your access if you violate these Terms, if required by law, or if necessary to protect the Service or other users. On termination, your right to use the Service ends; deletion of your data is handled as described in the Privacy Policy. Sections that by their nature should survive (including content license for already- contributed de-identified data, IP, the obligations in Section 12 that apply to information you received through a connection, disclaimers, limitation of liability, indemnification, and dispute resolution) survive termination.

17. Governing law and disputes

These Terms are governed by the laws of England and Wales, without regard to conflict-of-law rules. Subject to any non-waivable rights you have under local consumer-protection law, the courts of England and Wales will have jurisdiction over disputes. Where the law gives you the right to bring proceedings in your home country, this section does not remove that right.

18. Changes to these Terms

We may update these Terms from time to time. We will post the updated version here and revise the “last updated” date. For a material change we will give you at least 30 days’ notice before it takes effect, both in the app and by email to the address on your account. A change may take effect sooner only where it is required by law or a regulator, is needed to address a security risk, or introduces a feature or a new part of the Service that is optional, takes nothing away from you, and that you do not have to use; in those cases we will still tell you as soon as we reasonably can. That last exception never covers a change that would send your information to a new kind of recipient: a change like that always gets the full 30 days, as this one did. Your continued use after the changes take effect means you accept them; if you do not accept them, you may stop using the Service and delete your account at any time before then.

19. General

These Terms and the Privacy Policy are the entire agreement between you and us about the Service. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Neither party is liable for delays or failures caused by events beyond its reasonable control. Notices to you may be given in-app or by email; notices to us must be sent to hi@selfassay.com.
