Mozhi

Privacy Policy

Effective date: August 14, 2026

Mozhi is a German learning app for Android, developed and maintained by Anto Subash. This policy explains what it does with your information.

It collects nothing. There is no account, no sign-in, no analytics, no advertising, no crash reporting, and no tracking of any kind. Nothing you do in the app is sent anywhere, because there is nowhere to send it: the app has no backend.

1. What stays on your device

Everything:

  • which drill questions you answered, and whether you got them right
  • your vocabulary deck and its review schedule
  • articles you have opened, and which you have read
  • your settings

All of it lives in a database inside the app’s own private storage on your phone. It is never uploaded. Uninstalling the app deletes it, and Settings → Reset all progress deletes it while keeping the app.

2. When the app uses the network

Three times, and never to send anything about you:

  • Translation models — downloaded once from Google ML Kit so translation can run on your device.
  • Reading articles — a request to klexikon.zum.de for a selection of encyclopedia articles.
  • News headlines — a request to rss.orf.at for the public ORF news feed.

Translation itself runs on your device. Once the two ML Kit models are downloaded, no text you tap or select is transmitted anywhere — not the word you looked up, not the passage you translated.

Opening a news story hands the link to the browser you have chosen, and from that point the publisher’s own privacy policy applies.

3. Permissions

The app requests internet access, for the three requests above. Nothing else — no location, no contacts, no camera, no microphone, no files.

Text-to-speech, if you use it, is handled by the speech engine already installed on your phone. Mozhi asks it to speak a German word; what that engine does is governed by its own policy, and on most phones it also runs locally.

4. Children

The app collects nothing from anyone, including children.

5. Content sources

Mozhi’s vocabulary is derived from Wiktionary (CC BY-SA 4.0) and Tatoeba (CC BY 2.0 FR); reading articles come from the Klexikon (CC BY-SA 4.0) and news headlines from the ORF feed. These are credited in the app itself, at the foot of Settings.

6. Changes to this policy

If this ever changes, the effective date at the top of the page changes with it. Since the app collects nothing, any change would be about the sources above rather than about your data.
