Privacy policy

In short: Tennis Season Coach has no account, no server of its own, no ads and no tracking. Everything you enter stays on your device – and, if you use iCloud sync, in your own iCloud.

What data the app processes

• Information you enter yourself: players’ first names, groups, weapon, notes, skill check ratings, points, camp and season plans, coach name and club, your equipment.
• This data is stored in the app’s local storage on your device. It is not transferred to us. The only exception is iCloud sync (see below), which runs through your own Apple Account.
• If you save a feedback card as an image or copy and send a text, you decide where that data goes.

Purchases and subscriptions

Purchases and subscriptions are handled entirely by Apple, which processes your Apple Account and payment data under Apple’s privacy policy. The app only receives a signed confirmation from Apple stating which product is active for your Apple Account and until when, and stores it on your device to unlock features. We only receive aggregated sales reports from Apple (e.g. country, product, date, revenue) without your name, email address or payment data. Legal basis: Art. 6(1)(b) GDPR (performance of a contract).

Sharing by code

Coaches can send individual players a code. It only contains that player’s information (weapon, focus, homework, skill check) plus the season plan and camp details. The code is sent via the messenger or app of your choice and only decoded on the player’s device – there is no server in between.

iCloud sync (iPhone and iPad)

In the iOS app you can use iCloud sync so that your iPhone and iPad show the same data. It is on unless you switch it off under “Info”, and it only works if you are signed in to iCloud with your Apple Account on the device. The app stores a copy of your entries in the iCloud key-value storage of your Apple Account (1 MB at most). Apple operates this storage for you; only devices with your Apple Account and this app can read it. We have no access to it and do not receive a copy. Apple’s privacy policy applies; Apple may also process data outside the EU. Legal basis: Art. 6(1)(b) GDPR (the feature you requested). If you switch sync off, no new data is transferred; to delete the existing copy, remove Tennis Season Coach data in iOS Settings under Apple Account → iCloud → Manage Storage, or choose “Delete all data” beforehand.

Notifications and Live Activity

When you start a session with the timer, the app schedules notifications on your device for each block change and shows the timer on the Lock Screen and in the Dynamic Island. iOS asks for your permission once. The notifications are created locally on your device; there are no push notifications from a server and we learn nothing about them. You can turn both off at any time in iOS Settings.

Widgets and Siri

For the Home Screen and Lock Screen widgets and for Siri shortcuts, the app stores your next sessions (date, time, focus, number of players) in a shared storage area on your device that only Tennis Season Coach and its widgets can read. If you use Siri, Apple processes your voice request under Apple’s privacy policy; the app itself only receives the recognised command, for example “Start training”.

Calendar

If you choose “Add to calendar”, the app adds your planned sessions to your calendar as events. iOS asks for your permission once. The app only gets write access: it cannot read, change or delete events. Once added, the events belong to your calendar and are stored and synced by Apple or your calendar provider, depending on your settings.

Backups

When you create a backup, the app creates a file with your data. You decide in the iOS share sheet where it goes – Files, iCloud Drive, AirDrop or a message. We do not receive a copy.

Report a problem

The app keeps the latest technical error messages on your device. Only if you choose “Report a problem” and send the prepared email yourself do we receive these messages together with app version, device type and language. Names, notes and ratings are not included. We only use this information to fix the error and delete the email afterwards. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a working app).

Children’s data

If you as a coach enter data about your players, you are responsible for it. Only enter what you need for training – usually a first name is enough – and obtain parental consent for minors before sharing ratings. We do not receive this data.

Apple, App Store and TestFlight

The app uses Apple services for download, updates, purchases and testing. Apple processes its own data, such as your Apple Account, crash reports (only if you allowed sharing with developers in iOS settings) and – in TestFlight – usage and device data. Apple’s privacy policy applies.

Our website

When you visit this privacy policy or other pages on ertl-apps.de, the website privacy policy applies.

Retention and deletion

Data in the app is kept until you delete it – under “Info” with “Delete all data” or by removing the app from your device. If iCloud sync is on, “Delete all data” also deletes the data on your other devices and in iCloud. Purchases remain stored with Apple and can be restored after reinstalling.

Your rights

You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR). As we do not store any data about you, we usually hold no data; you can exercise most rights directly in the app. You can also lodge a complaint with a data protection authority, in Bavaria the Bayerisches Landesamt für Datenschutzaufsicht (BayLDA).

Fonts and content

The app contains all fonts and content itself and does not load anything from the internet.
