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 exclusively in the app’s local storage on your device. It is not transferred to us or to third parties.
• 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.

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. 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.
