Tuhei Privacy Policy
Summary
Tuhei processes your photos entirely on your device. The app does not upload, collect, store on any server, sell or share your photos or any personal data.
No network access
Tuhei does not request the Internet permission. The app cannot send data off your device.
Photos
Photos you select, capture or share into Tuhei are read on your device only for editing. While you edit, a temporary working copy is kept in the app's private cache and is removed when you close the editor or shortly afterwards. Exported photos are saved as new files in the Pictures/Tuhei folder (PDF files in Documents/Tuhei) on your device. Your original photos are never modified or overwritten.
Text recognition
Text detection uses an on-device model that is included in the app. Photos are not sent anywhere for recognition.
Face detection
Face detection uses an on-device model that is included in the app. It only finds where faces are so they can be covered. It does not identify people, and no face data is stored or sent anywhere.
Metadata
By default, exported photos contain no EXIF metadata (location, device, time). You can choose to keep EXIF data when exporting JPG files.
Permissions
Tuhei uses the system photo picker and the system camera app, so it does not need photo, storage or camera permissions on current Android versions. On Android 9 and earlier, the storage permission is requested only to save exported photos.
No accounts, ads or analytics
Tuhei has no accounts, no advertising, no analytics and no crash-reporting services.
Children
Tuhei does not collect personal data from anyone, including children.
Changes
If this policy changes, the updated version will be published at the same address and included in the app.
