PRIVACY
Grades, notebooks and dates stay on your device (saved with your device backup). Board scans and voice notes run on the device. No AI, no account, no tracking, no ads, no purchases. Only the dictionary looks words up online: OpenThesaurus, and Wiktionary only after a parent turns it on. Only the searched word is sent, without a name and without an account (as with any web request, the server sees the IP address). External websites, except the imprint, privacy policy and terms of use, open only after a parent allows it.

LANGUAGE
German and English, switchable in Settings.
