100 Kanji is a kanji-learning app that runs entirely on your device. We built it to collect no data at all.
100 Kanji does not collect, store, transmit, or share any personal information. There are no accounts, no sign-in, no analytics, no advertising, and no tracking of any kind.
Your learning progress (mastery levels, review history, streaks, and achievements) is stored only on your device. It never leaves your device and is not accessible to us or anyone else. Deleting the app deletes this data.
The app makes no network connections. All kanji data, dictionaries, and study material are bundled with the app and work fully offline.
Because 100 Kanji collects no data from anyone, it collects no data from children.
If the app's privacy practices ever change, this page will be updated and the change will be noted in the App Store release notes.
