Terms of Use
Last updated: 2026-09-24
These terms govern your use of Tennis Assistant (the “App”) and its Pro subscription. By downloading or using the App you agree to these terms. If you do not agree, please do not use the App. If you obtained the App from the Apple App Store, Apple's standard End User License Agreement (EULA) also applies.
1. License
You are granted a non-exclusive, non-transferable, revocable license to use the App on your own devices for personal, non-commercial purposes. You may not copy, modify, reverse engineer (except where permitted by law), rent, sell or redistribute the App. All rights in the App belong to the developer.
2. Pro subscription
- Scope: Pro unlocks additional features such as AI Coaching and cloud sync (iCloud on iOS, Google Drive on Android). Core features (match, training and equipment tracking) are free.
- Term and price: Offered monthly or yearly. The current price is shown in your local currency on the store screen before purchase and is charged to your store account.
- Auto-renewal: The subscription renews automatically for the same term at the then-current price unless cancelled before the period ends.
- Free trial: When offered, the trial is only for users who have never subscribed before. If you do not cancel before the trial ends, the paid period starts when it ends.
- Cancellation: You can cancel at any time on Android in Google Play > Payments & subscriptions > Subscriptions, and on iOS in Settings > Apple Account > Subscriptions. Cancellation takes effect at the end of the current period; Pro features stay on until then. Deleting the App does not cancel the subscription.
- Refunds: Payments are processed by Google Play or Apple, so refund requests are subject to the respective store's refund policy.
- Restore: You can use your subscription on another device signed in to the same store account via “Restore purchases”.
3. AI Coaching and health information
AI Coaching suggestions are generated automatically by artificial intelligence from your match and training summaries; they are for information only, may be inaccurate or incomplete, and are not a substitute for a professional coach or for health or medical advice. Values such as heart rate, calories and duration are estimates from device sensors and must not be used for medical purposes. You are responsible for considering your health before physical activity.
4. Your content and data
The content you enter belongs to you and is primarily stored on your device. How data is handled is described in the Privacy Policy. We recommend keeping backups against data loss from device loss, deletion, or while sync is off.
5. Third-party services
The App uses third-party services for some features, such as Apple, Google (Google Play, Google Drive, Health Connect, Wear OS) and the AI provider Anthropic. Use of these services is subject to the respective provider's terms, and the developer is not responsible for their outages.
6. Disclaimer of warranties
The App is provided “as is” and “as available”. To the extent permitted by applicable law, no express or implied warranty is given that the App will be uninterrupted, error-free or fit for a particular purpose.
7. Limitation of liability
To the maximum extent permitted by applicable law, the developer is not liable for any indirect, incidental or consequential damages (including data loss) arising from the use of or inability to use the App. In any case, total liability is limited to the amount you paid for the App in the last 12 months. Your statutory consumer rights that cannot be waived by contract are not affected.
8. Termination
Your license ends automatically if you fail to comply with these terms. You can stop using the App at any time by deleting it (an active subscription must also be cancelled in the store).
9. Changes
We may update these terms from time to time. Updates are posted on this page and the “Last updated” date above changes accordingly. Continuing to use the App after a change means you accept the updated terms.
