Privacy Policy

Last updated: July 2026

Deutsch Üben is a free set of German grammar practice tools. This policy explains, in plain language, what happens to your information when you use the site.

No accounts, no personal data

You can use every app on this site without registering. We do not collect, request, or store names, email addresses, passwords, or any other personal information. There is no login, and no user database.

Your progress stays on your device

Each app saves your practice history — words seen, answers marked correct or wrong, and accuracy statistics — using your browser's localStorage. This data:

• is stored only in the browser on the device you are using;
• is never transmitted to us or to any server;
• is not shared between devices, and is not visible to us;
• can be deleted at any time by using the reset button inside each app, or by clearing your browser data.

Analytics

We may use privacy-respecting web analytics to understand how many people visit the site and which apps are used. Any such measurement is aggregate only — it does not identify individuals and is not linked to your practice data.

Advertising

This site displays advertising provided by Google AdSense to keep the apps free. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites.

You can opt out of personalised advertising in Google Ads Settings, or learn more at Google's advertising policies. Ads are handled entirely by Google; we receive no personal data from them.

Cookies

Deutsch Üben itself does not set tracking cookies. Cookies present on the site come from the advertising provider described above.

Children

The site is suitable for all ages and does not knowingly collect information from anyone, including children.

Changes to this policy

If this policy changes, the revised version will be published on this page with an updated date.
