Klingelklar collects no data from children and does not connect to the internet. Learning progress, the test date, and the first name for the certificate stay on your device. No advertising, no tracking, no third-party services.

The app does not need an account, and we do not run any servers for it. The app contains no advertising, no tracking, no analytics, and no third-party services, and it does not connect to the internet.

The learning progress (e.g., completed chapters, wrong answers to repeat, test results, collected bells), the settings, the test date, and the child's first name, which parents enter in the parent area for the certificate, stay on your device. They are part of the regular iOS device backup, to which we have no access. Deleting the app deletes this data.

Klingelklar is made for children of primary school age and for the Kids category of the App Store. We do not collect any data from children. The parent area, links, e-mail, and printing or sharing the certificate are behind a parental gate (an arithmetic task) so that children do not leave the app by accident.

The app reads texts aloud with the speech synthesis built into iOS. It runs on your device; no texts are transmitted.

The certificate only leaves your device if you print or share it yourself.

If you write to us from the parent area, your mail app opens with a prepared subject line. No further information is attached. We only use your message and e-mail address to answer your request.

You get the app through the Apple App Store. Apple is responsible for download, payment, and updates; we have no access to that data. Apple's privacy policy applies: https://www.apple.com/legal/privacy/

If you have turned on "Share with App Developers" in the iOS settings, Apple provides us with anonymous crash reports and usage statistics. They do not identify you.

Whatever happens only on your device or in your private iCloud does not reach us; we do not process that data.

If you e-mail us, we process your address and message to answer you (Art. 6(1)(b) GDPR for questions about a purchase, otherwise Art. 6(1)(f) GDPR).

What the app stores on your device stays there until you delete it in the app or remove the app. Data in your iCloud can be deleted in your device's iCloud settings.

We delete e-mails to us once your request has been resolved, unless statutory retention obligations apply.

You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and to object to processing based on legitimate interests (Art. 21). You can withdraw consent at any time with effect for the future (Art. 7(3)).

Since we do not keep accounts and the app does not identify you, we often cannot attribute data to a person (Art. 11 GDPR). Write to us anyway; we are happy to help.

You can lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example the one responsible for us: the data protection authority of Lower Saxony (LfD Niedersachsen), Prinzenstraße 5, 30159 Hannover, Germany, https://www.lfd.niedersachsen.de
