Where your data lives
Everything stays in DocuPair's private storage on your phone. There is no account and no server of ours, so there is nothing to breach on our side and nothing we can hand over.
How it is protected
Page images, and the name, notes and recognised text of each document, are encrypted by the app with AES-256-GCM. The key is random, stored only in wrapped form, and protected by a key held in the Android Keystore that never leaves the device's secure hardware or system service. On top of that, Android encrypts the phone's storage. The app is excluded from Google cloud backup and device transfer.
App lock
Optionally, DocuPair asks for your biometrics or device passcode each time it opens or returns from the background, and hides its contents in the app switcher.
While the lock is on, Android also blocks screenshots and screen recording of the app.
What leaves your device
- Nothing you scan. Images, names, notes and recognised text are never uploaded.
- Purchases: the store handles the unlock; we receive only the confirmation that it was bought.
- What you share: files you export go where you send them.
- Trial date: one date is kept in Google Play services' Block Store so that reinstalling does not restart the trial; Google may back it up to your Google account.
- Technical diagnostics: Google's text-recognition component sends Google anonymous diagnostics (device model, app version, performance figures, error codes), never your images or text.
Permissions the app asks for
- Camera (to scan).
- Notifications (optional reminders).
- Biometrics or screen lock (only if you turn on the app lock).
DocuPair does not ask for contacts, location, microphone, calendar or access to all your photos.
Sharing copies safely
Add a watermark that names the recipient and the purpose, protect the PDF with a password and send the password by another route. Delete the copy from the receiving app's downloads when you no longer need it.
If you lose your phone
Your documents are protected by your phone's lock screen, by the encryption of your phone and, if you turned it on, by the app lock. Use your platform's find-and-erase features to wipe the phone if needed.
Reporting a security issue
If you find a security problem, please write to support@unselstudio.app before making it public, and we will respond as quickly as we can. DocuPair has not been through an independent security audit.
