Keybound
Your life, locked down. An offline paperwork vault. Encrypted on your phone. No account. No ads.
Keybound is an offline paperwork vault for Android, made by G&R Mad Lab 42 LLC. Your files stay on your phone, locked with a vault password plus your fingerprint or screen lock. There is no Keybound account and no ads, and Keybound has no internet permission and no camera permission.
What it does
- Keeps passwords, papers, and private stuff in a locked vault on your phone
- No internet permission, no account, and no ads
- Vault password plus fingerprint or screen lock, with a recovery key
- Dead Drops: a note sealed with its own passphrase, as a file or a QR code
- A decoy vault, opened with a second password, so the real vault stays hidden
- YubiKey support for Dead Drops
- Business books, scan and sign, and smart reminders
- Keybound never deletes your vault on its own
Depending on the plan, Keybound also includes binders for everyday papers, a key vault, an inventor and IP notebook, a music locker for music files you already own, and more. The full list will be on the Google Play store listing when Keybound is published.
Your data, your keys
Files are encrypted on the phone twice (AES-256 and XChaCha20), plus a post-quantum ML-KEM layer. There is no email password reset and no back door. We cannot open your vault. If you uninstall the app or reset the phone, the vault on that phone is gone, so keep your encrypted backup file and recovery key.
