In short
DeutschCampus is a website and app for learning German. You can use it without an account; then your progress stays only in your own browser (localStorage) and never reaches us. No ads, no tracking, and your data is never sold or shared with anyone.
What we keep if you sign in with Discord
- Account: your Discord ID (a number), username, display name and the address of your avatar. We do not collect an email address or a password.
- Session: only a hash of the session cookie in your browser; we do not hold the cookie itself.
- Learning progress: the lessons you have finished, your word deck (boxes and review dates), quiz results, daily activity (pages, lessons, review counts, XP) and game scores.
- Answers: a learning record of the answers you give (which question, right/wrong, time taken, and the short answer you typed if it was wrong) — your skills and your mistake notebook are calculated from these. The raw answer record is deleted after 400 days; the summaries (skill levels) remain.
- League and duels: your name and avatar are visible to other participants in the weekly league only if you join it. In a duel, your opponent sees your name and score.
- German assistant: the texts you send to the assistant and the feedback you receive are kept for 90 days, then deleted. The model runs on our own server; your texts do not go to any third-party AI company.
- Reading from a photo: the photo you send is written to a temporary file only to read its text and is deleted right away; neither the photo nor the text read from it is kept.
Discord server
If you join the Discord server, the bot also keeps your level role on the server, quiz results, voice channel time and streak; if you have a web account, your Discord quiz answers are written to the same learning record.
App permissions (Android)
Internet (to open the site), microphone (only when you press the speak-to-type button; you are asked the first time you use it; your device’s speech recognition service turns your voice into text, and only the text reaches us) and the file picker (for reading from a photo; only the file you choose). There is no location, contacts or any other permission.
Storage and security
Data is kept on our own server and only travels over an encrypted connection (HTTPS). Daily backups are kept for 14 days and only the server administrator can access them.
Deleting your data
The “Delete all my data” button on the profile page deletes your account and all of the data above immediately. Details: Account deletion. It also drops out of the backups within 14 days at the latest.
Contact
For questions and deletion requests, you can write to the admins on our Discord server.
