Tonus
Terms of Service
Last updated: September 8, 2026
By using Tonus you agree to the terms below. They describe the service, what you may and may not do, and the limits of liability.
1. Service
Tonus is an iOS recovery and training app for Apple Watch and iPhone. It includes an on-device AI coach and, optionally, social sharing features.
2. Eligibility
You must be at least 13 (16 in the European Union) to use Tonus. Below that age, a parent's permission is required.
3. Licence
We grant you a personal, limited, non-transferable, revocable licence to use the app on Apple devices you own or control.
4. Subscriptions and in-app purchases
Some features require a subscription managed by Apple's App Store. Unless cancelled at least 24 hours before the end of the period, the subscription renews automatically at the price displayed. Refunds follow Apple's policies.
5. User content
If you use the social features to share workouts, you keep the rights. You grant us a non-exclusive, royalty-free licence to host and display that content within the service.
6. Intellectual property
The app, its code, design, logo, and mark belong to their author. You get no rights beyond the licence above.
7. Health disclaimer
Tonus is not a medical device. The scores and recommendations are indicative and do not replace the advice of a healthcare professional. Consult a doctor before any significant change to your training, in case of symptoms, or for any health question.
8. Prohibited use
No reverse engineering, decompilation, automated data scraping, publication of illegal or harmful content, or any use that would disrupt the service.
9. Termination
We may suspend or terminate your access in case of a clear breach of these terms. You may stop using the app at any time by uninstalling it.
10. Limitation of liability
To the fullest extent permitted by applicable law, Tonus is not liable for indirect, incidental, or consequential damages. Total liability is capped at the amount you paid for the app in the last twelve months.
11. Governing law
These terms are governed by French law. Courts of Paris have jurisdiction, subject to mandatory consumer-protection rules.
12. Changes
For any material change, you'll be notified in the app. Continued use of Tonus counts as acceptance of the new version.
