Privacy Policy

2. Server log files

The web server automatically processes technically necessary data such as IP address, date and time, requested file, referrer, browser, operating system and status code. This ensures secure and stable operation. The legal basis is Art. 6(1)(f) GDPR.

3. Classes stored in your browser

Saved classes and name lists are stored exclusively in your browser's localStorage. They are not transmitted to us or stored on our servers. The data remains until you delete the saved class or browser storage.

The legal basis for access to the device is Section 25(2)(2) TDDDG, because storage is necessary for a function explicitly requested by you. Where possible, use neutral identifiers instead of students' names.

4. Analytics

We use our self-hosted Matomo installation to measure page views and improve this website. Matomo is loaded only after you have expressly consented to optional analytics. Without consent, neither the Matomo script nor the tracking endpoint is requested.

The legal basis is Art. 6(1)(a) GDPR and Section 25(1) TDDDG. You can withdraw or change your consent at any time with effect for the future.

5. Your rights
