Terms of use

1. The service

Willn provides adults with an AI coach for fitness, general nutrition, recovery and habits, in Messages and in the Willn app for iPhone. The coach’s name can be personalized, but it is always an AI, not a person.

2. Access requirements

You must be 18 or older, provide accurate information and separately consent to the processing of any health data you choose to send. In the app, the account is created with Apple or an e-mail address. A phone number is only requested for iMessage, and it must be your own. Test access may be changed or interrupted.

3. Not a medical service

Willn does not replace a doctor, dietitian or healthcare professional. Replies and estimates may be inaccurate. Never use Willn for an emergency, diagnosis, prescription, eating disorder, high-risk pregnancy, serious injury or medical decision. In an emergency, call 15 or 112 (112 works across Europe). If you have suicidal thoughts, call 3114 in France (free, 24/7).

4. Permitted use

You may use Willn for training, general nutrition, recipes and groceries, hydration, sleep, recovery, habits and progress tracking. Bypassing limits, automating abusive volumes, attacking the service, impersonating someone else, sending illegal content or using Willn as a general-purpose assistant unrelated to coaching is prohibited.

5. Messages, availability and accuracy

Follow-up times depend on the information you provide, and delivery times are not guaranteed. Transport relies on iMessage and local automation that Apple does not offer as an official business API: Apple may change, limit or suspend this functionality. Calories and macros derived from a photo are estimates. You remain responsible for checking that exercises, foods and guidance are suitable for your situation.

6. Suspension and stopping

Willn may temporarily suspend an account if security is compromised, behavior is abusive or the monthly AI cost cap is reached. You can reply STOP, withdraw consent or delete your account through the privacy portal. In the app, you can sign out from your Profile; account deletion from the app is being prepared.

7. Data and intellectual property

The privacy policy describes how your data is used. You retain your rights to the content you send and grant only the permissions needed to provide the service. Willn’s trademarks, software and proprietary content remain protected.

8. Free access during the test phase

Access is free during the test phase, with no three-day trial, no card and no charge. The beta may change or end; it never automatically becomes a paid subscription. Any future paid offer will be explained separately and require your explicit agreement before payment.

9. Paid subscriptions (not on sale yet)

Subscriptions are not on sale yet: today, Willn is a free beta. This section announces the conditions planned for their launch. Before any purchase, the App Store will show the price, duration, free trial and first payment date, and you will have to confirm the purchase.

• Sale: subscriptions will be purchased in the app, through the App Store. Apple Distribution International, which operates the App Store in France, sells them and collects payment on Willn’s behalf. The service is provided by Willn, whose publisher is identified in the legal notice.
• Planned plans, prices including VAT: App at €7.99 per month or €59.99 per year; App + iMessage at €15.99 per month. The App plan does not include the conversation in Messages. No commitment beyond the current period.
• 7-day free trial for a first subscription. The first payment is taken at the end of the trial. To pay nothing, cancel at least 24 hours before the trial ends. A cancelled trial cannot be resumed.
• Payment: through the App Store, with the payment method of your Apple Account. Willn never receives your bank details.
• Automatic renewal: the subscription renews for the same duration and at the same price unless cancelled at least 24 hours before the end of the current period. The renewal is charged within the 24 hours before the end of the period. If the price increases, Apple notifies you by e-mail at least 30 days before the renewal, and you can cancel at no cost before it applies.
• Cancellation: at any time, in the iPhone Settings app: tap your name, then Subscriptions. Access remains open until the end of the period already paid. Deleting the app or your Willn account does not cancel the subscription: you must also cancel it with Apple.
• Refunds: they are handled by Apple, under its terms, at reportaproblem.apple.com. Willn cannot itself refund a purchase made in the App Store.
• Right of withdrawal: you can withdraw within 14 days, without giving any reason. The period runs from the purchase of the initial subscription, including the free trial. Coaching starts right away, at your request: this immediate start does not remove that right. During the trial, simply cancel: nothing is charged. After the first payment, withdrawal is requested from Apple, which sells the subscription: in the purchase history of your Apple Account, at reportaproblem.apple.com, or with the model withdrawal form sent to rightofwithdrawal@apple.com. Apple refunds within 14 days. You can also write to Willn’s customer support (address to be completed): we will help you with the process.
• Beta testers: the 20 testers will have the App + iMessage plan free for 14 days, with no card. This access will never turn into a paid subscription on its own: to continue afterwards, you will subscribe yourself in the App Store, at the displayed price.
• App licence: in addition to these terms, the app is provided under Apple’s standard licence for App Store apps.

10. Complaints, mediation and applicable law

Mandatory consumer rights remain unchanged. For any complaint, first write to Willn’s customer support: e-mail address to be completed. If the disagreement persists, you can refer the matter free of charge to Willn’s consumer mediator, no later than one year after your written complaint: name, address and website to be completed.

These terms are governed by French law. If you live in another European Union country, you keep the mandatory protections of your country. In the event of a dispute, you can bring the matter before the court of the place where you lived when you subscribed or when the event giving rise to the dispute occurred, or any other competent court.
