PaperCript

PaperCript stores your passwords on paper, encrypted.

You encrypt a password with your master password, the app turns it into a card with a QR code, and you print an A4 sheet of cut-out cards. To get a password back, you scan its QR and type the master password.

Losing the paper costs you nothing: a card is worthless without the master password. Keep them in a drawer, split them up, or leave a copy at a friend's place.

• scrypt key derivation, AES-256 + HMAC-SHA256 (encrypt-then-MAC)
• No network permission: the app cannot open a socket
• Stores nothing: no passwords, no master password, no history
• No screenshots (FLAG_SECURE), sensitive clipboard cleared automatically
• Built-in password generator
• QR codes read with ZXing, no proprietary libraries

- Store listing now has an icon and screenshots.
- Release APK is built reproducibly, so F-Droid can verify it against the source.
- No changes to the app itself.
