MRX Labs is developing an offline Android manager for passwords, keys, notes, recovery codes, and other secrets.

Landing page captured for the 2026-09-12 issue.

Field notes

The proposed vault keeps passwords, payment cards, notes, API and SSH keys, 2FA recovery codes, and .env files together on the device rather than syncing them. The page names XChaCha20-Poly1305 for encryption, Argon2id for key derivation, and SQLCipher for the database, while stating that Android 11+ is supported. It also claims the app will request no internet, storage, or contacts permission; the first Google Play release remains in development.
