Terms of use
In short: the player role is free. You buy the Performance Camp once; Pro is a subscription you can cancel at any time in your Apple Account settings. All payments go through Apple.
1. Scope
These terms apply to the app “Playbook Tennis” for iPhone and iPad and to its web version. The provider is Philip Ertl, Bürgermeister-Panzer-Straße 10, 83629 Weyarn, Germany (“provider”, “we”). For apps from the App Store, Apple’s Licensed Application End User License Agreement (“Apple EULA”) applies in addition. Apple is not a party to these terms and is not responsible for the app or its content.
2. What the app offers
The app provides training plans, drill cards, camp and season planning and tools for tennis coaching. Part of it is free, in particular the player role. Further content can be unlocked:
- Performance Camp (one-time purchase): stays unlocked for your Apple Account permanently.
- Pro (subscription, monthly or yearly): includes the Performance Camp plus the season planner and further features for as long as the subscription is active.
The app shows you before purchase which features are free and what a purchase or subscription unlocks. We keep developing the app. We will not remove paid features you bought during the paid term.
3. Purchase and payment
Purchases and subscriptions are made exclusively as in-app purchases with your Apple Account. Apple handles payment, invoicing and sales tax; we do not receive any payment data. The price shown in Apple’s purchase dialog applies; it includes sales tax and may differ by country. “Restore purchases” unlocks your purchases on other devices with the same Apple Account.
4. Subscriptions, free trial and cancellation
- Renewal: A subscription renews automatically for the same period (one month or one year) at the then current price unless you cancel it at least 24 hours before it ends. Apple charges your Apple Account within the last 24 hours before the period ends.
- Free trial: If we offer a trial, the purchase dialog shows its length. You can use it once per Apple Account. Unless you cancel at least 24 hours before it ends, it converts automatically into the paid subscription. If you cancel during the trial, you can keep using the features until it ends.
- How to cancel: On iPhone or iPad: Settings → your name → Subscriptions → Playbook Tennis → Cancel Subscription. Deleting the app does not cancel a subscription.
- Price changes: Apple informs you about price changes in advance. For increases, Apple’s rules apply, which in many cases require your consent.
5. Withdrawal and refunds
App Store purchases are governed by the Apple Media Services Terms and Conditions. In the EU these generally let you cancel an order within 14 days of receiving the invoice without giving a reason – in your Apple Account under “Purchase History” or in the other ways Apple describes. Subscriptions can only be withdrawn after the initial purchase. Refunds are handled exclusively by Apple; we cannot refund payments ourselves. If you have a problem with a purchase, we are glad to help at [email protected].
6. Minors
The app is intended for coaches. Young players may use the player role, which is free. Minors may only make purchases and start subscriptions with their parents’ consent. Parents can use Apple’s Family Sharing (“Ask to Buy”) and Screen Time to require approval for every purchase.
7. Training content and responsibility
The drills and plans are suggestions for qualified coaches and for players. Whoever leads the session is responsible for adapting it to age, health and level, for safety on court and for supervising minors. If you have health problems, please seek medical advice.
8. Data and backups
Your entries are stored on your device only (see privacy policy). You are responsible for backing up your data; the app provides a backup function. Anyone who enters or shares players’ data is responsible for it under data protection law and obtains parental consent for minors.
9. Rights of use
Texts, drill cards, diagrams and plans in the app are protected by copyright. You may use, print and share them for your own coaching and with your players. Publishing them or redistributing them commercially, for example as your own product, is not permitted.
10. Availability
The app works offline. We aim to keep it compatible with new versions of iOS and iPadOS but cannot guarantee that it will run on every device and system version indefinitely.
11. Liability
We are liable without limitation for intent and gross negligence and for injury to life, body or health. For slight negligence we are only liable for breach of essential contractual obligations and limited to the foreseeable, typical damage. Liability under the German Product Liability Act remains unaffected.
12. Changes
We may amend these terms for objective reasons such as new features or changes in the law. The app informs you about material changes in advance. The terms in force at the time of purchase continue to apply to periods you have already paid for.
13. Final provisions
German law applies. Mandatory consumer protection rules of your country of residence remain unaffected. We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board. Contact: [email protected].
