Terms of Service

Last updated August 26, 2026

1. Who you are dealing with

The YHAP app and the website yhap.ai (the “Services”) are provided by YHAP Inc., 251 Little Falls Drive, Wilmington, Delaware 19808, United States (“YHAP”, “we”). Contact: hi@yhap.ai.

By creating an account or using the Services you agree to these Terms. If you do not agree, do not use the Services. Our Privacy Policy explains how we handle your data and is part of the deal.

2. Who can use YHAP

3. What YHAP is — and is not

YHAP turns data from Apple Health, your own entries, blood tests and conversations with an AI coach into scores such as Bio Age and Vibe, insights, daily targets (“arcs”) and social features (“crews”).

YHAP is not medical advice. Everything in the app — scores, insights, coach replies, nutrition estimates, blood-value readings — is general wellness information. It is not diagnosis, treatment or a substitute for a doctor, and it is not an emergency service. Do not change medication, training or diet on the basis of YHAP without talking to a qualified professional. If you have symptoms or an emergency, contact a healthcare provider or emergency services.

4. AI features

Parts of the Services are generated by artificial-intelligence models (currently provided by OpenAI). AI output can be incomplete, wrong or not applicable to you — for example a calorie estimate from a photo or a value read from a lab report. Check anything that matters. We do not guarantee the accuracy of AI output or any health outcome, performance improvement or change in a score.

The Services process health data — sensitive personal data. We ask for your explicit consent in the app before we connect to Apple Health and before AI features process your data, and you can withdraw it at any time (see the Privacy Policy). Without that consent, core features will not work.

Only upload data about yourself, or about someone else if you have their permission. Only upload documents you are allowed to share.

6. Your content

“Your Content” is what you provide: entries, photos, uploads, messages, notes. You own it. You grant YHAP a worldwide, non-exclusive, royalty-free licence to store, process, reproduce and display Your Content only to provide, secure and improve the Services for you — including generating your outputs, running crews you joined, and providing support. The licence ends when you delete the content or your account, except where we must keep records by law.

7. Crews, clubs and community rules

Crews, wellness clubs and Explore let you share parts of your activity with other users; the Privacy Policy lists exactly what. Joining is your choice and you confirm what is shared when you join.

When you interact with others you agree not to: harass, threaten or discriminate against anyone; impersonate people; post content that is illegal, sexual, violent or misleading; share other people’s personal or health data without permission; or misuse invite codes. You can block and report users. We may remove content, remove you from a crew, or suspend accounts that break these rules.

8. Acceptable use

You agree not to: break the law or others’ rights with the Services; reverse-engineer, scrape, probe or overload the Services; use bots, scripts or automated access without our written consent; try to extract our models, prompts or other users’ data; or resell access. We may suspend or terminate accounts that create legal, security or abuse risk.

9. YHAP Pro subscription

10. Advertising

We may show advertising and sponsored content in the app. Ads are never selected using your health data, and advertisers never receive it (Privacy Policy §8). Personalised ads are shown only if you allow tracking; otherwise you see non-personalised ads. YHAP Pro removes ads [confirm]. Advertisers are responsible for their own products and claims; an ad in YHAP is not a health recommendation from us.

11. Third-party services

The Services rely on third parties (Apple, Clerk, OpenAI, Cloudflare, Railway, PostHog, OneSignal, RevenueCat, Open Food Facts) and may link to external sites. Their terms and policies govern their services. We are not responsible for third-party content, but we remain responsible for our processing of your data as described in the Privacy Policy.

12. Intellectual property

The Services — software, design, models, scores, texts, trademarks and the names “YHAP”, “Bio Age”, “Vibe”, “Aura” and the arc names — belong to YHAP or its licensors. You get a personal, non-transferable, revocable licence to use the app on your devices. No other rights are granted. Feedback you give us may be used without obligation to you.

13. Availability and changes to the Services

We work to keep the Services available but do not guarantee uninterrupted operation. We may change, add or remove features, including scoring methods (which can change your Bio Age or Vibe), and may discontinue the Services with reasonable notice — in which case you can export your data before the end (Privacy Policy §12).

14. Termination

You can stop using the Services at any time and delete your account in the app. We may suspend or terminate your access if you breach these Terms, create risk for us or other users, or if the law requires. After termination we delete your data as described in the Privacy Policy.

15. Acceptance and changes to these Terms

You accept these Terms when you create an account; we record the version you accepted and the time. We may update these Terms. Material changes will be announced in the app or by email at least 14 days before they apply; if you do not agree, you can delete your account before then. Continued use after the effective date means you accept the new Terms.

16. Warranty and liability

Consumers in the EEA, UK and Switzerland: your statutory rights apply and nothing here limits them. We are liable without limit for damage caused intentionally or by gross negligence, for injury to life, body or health, and under mandatory product-liability law. For slight negligence we are liable only for breach of essential contractual duties, limited to the damage typical and foreseeable for this kind of service.

Everyone else, to the extent the law allows: the Services are provided “as is” and “as available” without warranties of any kind. We are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, data or goodwill, and our total liability is limited to the greater of the amounts you paid us in the 12 months before the claim or USD 100.

In all cases: YHAP is not liable for decisions you make about your health, training, diet or medication based on the Services.

17. Indemnity

If you are a business user, or where the law allows it for consumers, you will indemnify YHAP against third-party claims arising from Your Content or your breach of these Terms or the law.

18. Governing law and disputes

Consumers in the EEA, UK and Switzerland. These Terms are governed by the laws of the State of Delaware, USA, but this choice does not deprive you of the protection of the mandatory consumer law of your country of residence, and you may bring proceedings there. The informal-resolution, arbitration and class-waiver rules below do not apply to you. The European Commission’s online dispute-resolution platform is at https://ec.europa.eu/consumers/odr; we are not obliged and not willing to take part in proceedings before a consumer arbitration board.

Everyone else, including users in the United States. These Terms, and any dispute arising out of them or the Services, are governed by the laws of the State of Delaware, USA, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

19. Miscellaneous

If a provision is invalid, the rest stays in force. We may assign these Terms as part of a transfer of the business; you may not assign your account. These Terms are the whole agreement between you and YHAP about the Services. The English version is authoritative; translations are for convenience.
