Terms of Service

1. Purpose

Jyva is an AI-assisted training and nutrition application: program generation, meal scanning by photo, progress tracking, and an entirely optional community dimension. These Terms apply to the iOS application and the upcoming Android version.

2. Your account

• Jyva is reserved for individuals at least 16 years old.
• An account is strictly personal to you — you are responsible for its confidentiality.
• You can create an account via Sign in with Apple, Google, email, or guest mode.
• The information you provide (profile, goals, measurements) must be accurate — Jyva relies on it to generate your program and estimate your nutritional needs.

3. Subscription

• Jyva works on a subscription basis, without any limited free version or in-app purchases once subscribed — a 14-day free trial precedes the first charge.
• The subscription is managed directly by Apple's App Store (auto-renewal, price and duration displayed in the app before confirmation).
• You can cancel at any time from your Apple ID settings — access remains active until the end of the already paid period.
• Refunds are processed by Apple, not directly by Jyva — see the Refund Policy.
• AI meal scanning is subject to a daily usage limit, applied to all subscribed accounts — an anti-abuse safeguard for a real cost (calling an AI model), not a hidden paid tier.

4. Artificial intelligence and health

• The training program is generated by a deterministic algorithm based on your profile (goal, level, equipment, frequency).
• If you enable menstrual cycle tracking (optional), the adjustment of the suggested intensity during certain periods is a simple heuristic by date window, calculated on your device — not a hormonal model or medical advice. See the Privacy Policy for details.
• Meal scanning and the virtual coach use AI (GPT-4o) to estimate calories, macros and suggest advice — these are estimations, correctable at any time in the app, not certified measurements.
• Jyva does not provide professional medical, dietetic or paramedical advice. The app does not replace a consultation with a doctor, dietitian or healthcare professional — especially if you have a medical condition, are pregnant, or before starting an intense training program.
• You use Jyva's programs and recommendations at your own risk; it is up to you to assess your physical limits.

5. Community and content

The community dimension (feed, friends, challenges, duels, public programs) is entirely optional.

What you can publish

You remain the owner of the content you publish (shared workouts, public programs, comments). By publishing it, you grant Jyva the right to display it in the community feed or catalog to other users, to make this content accessible.

What is prohibited

• Illegal, insulting, harassing, discriminatory content or impersonating others
• Spam, unsolicited advertising, scam attempts
• Circumvention of the app's security or anti-abuse mechanisms

Reporting

You can report content or a profile that violates these rules via support — we will examine it and remove the content or suspend the account concerned if necessary.

6. Intellectual property

The Jyva brand, logo, Wiggl character, design and code of the application belong to the publisher — see the legal notice. No provision of these Terms transfers any rights to you beyond normal use of the app.

7. Liability

Jyva makes every effort to provide a reliable service, without guaranteeing absolute availability or accuracy (particularly for AI-generated estimations, see §4). Under French consumer law, our liability cannot be limited for gross negligence, willful misconduct, or any breach of an essential obligation of the service — in other cases, it is limited to direct and foreseeable damages related to the use of the app.

8. Termination

You can delete your account at any time — see the dedicated page. Jyva may suspend or terminate an account in the event of a manifest violation of these Terms (prohibited content, abuse of anti-fraud mechanisms, attempt to circumvent the subscription), after notification by email when possible.

9. Governing law and disputes

These Terms are subject to French law. In the event of a dispute, and after an attempt at amicable resolution with support, you can resort for free to a competent consumer mediator for the amicable settlement of the dispute. In the absence of an amicable resolution, the competent courts are those of your place of residence, in accordance with the mandatory rules of consumer protection.

10. Modification of the Terms

These Terms may evolve with the service. Any significant modification will be notified to you in the app before it takes effect; continuing to use Jyva after this notification constitutes acceptance of the new conditions.
