Privacy Policy
The KeyBoard collects nothing.
The short version. The KeyBoard does not collect, store off-device, transmit, sell, or share any personal data. The app declares no network permission (android.permission.INTERNET), so it is technically unable to send anything from your device. There are no analytics, advertising, crash-reporting, or tracking components.
1. About the warning Android shows
When you enable any third-party keyboard, Android displays a notice saying the input method may be able to collect all the text you type, including personal data such as passwords and credit card numbers. This is a standard warning shown for every input method. The KeyBoard processes what you type only to produce input on your device. It does not log your typing, and it cannot transmit it.
2. Data stored on your device
The following is kept in the app's private storage on your device, and nowhere else:
- Settings — input style, layouts, toolbar, display mode and size, trackpad, haptics, modifier-key mapping, physical-keyboard rules, and the list of apps you excluded from shortcuts.
- Japanese conversion history — the Mozc engine remembers words and phrases you choose so it can rank candidates better next time. You can remove an individual entry by long-pressing a candidate and choosing Remove.
All of this is deleted when you uninstall the app or clear its data from Android settings.
3. Permissions and system access
- Vibration (
VIBRATE) — haptic feedback on key presses. - Package visibility — the app queries the list of launchable apps so you can pick apps to exclude from shortcuts, and checks whether Shizuku is installed. The list is shown on screen only; nothing beyond your own selections is stored, and nothing is transmitted.
- Shizuku (optional) — if you grant The KeyBoard access in Shizuku, the app uses it to inject key events for physical-keyboard remapping and to create a virtual mouse device for the trackpad. Shizuku access is used for nothing else. All features other than those two work without Shizuku.
The app requests no access to contacts, location, microphone, camera, storage, or the network.
4. Backups
Android's built-in app backup may include The KeyBoard's settings and conversion history in your device backup, stored in your Google account according to your device's backup settings and Google's privacy policy. You can turn backup off in Android settings. The KeyBoard itself never uploads anything.
5. Third-party components
The app includes the open-source Mozc conversion engine (Google, BSD-3-Clause) with its dictionary, which runs entirely on-device, and the Shizuku API client library, which is used only for local communication with the Shizuku app on the same device. Neither contacts any server.
6. Children
The KeyBoard is not directed at children under 13, and it collects no data from anyone.
7. Changes
If this policy changes, the new version will be posted on this page with an updated effective date.
