Your passwords and private files,
locked in a vault only you can open.

Guarja is a zero-knowledge security vault for iOS and Android — a password manager and an encrypted folder for your sensitive files, photos, and videos. Everything is encrypted on your device with a key only you hold.

Phase 1 (device-only) is in active development. Encrypted cloud sync comes next.
🔒

Zero-knowledge by design

Your master password never leaves your device and is never stored. Not even we can read your vault.

🗝️

Passwords + Secure Folder

Logins, cards, 2FA codes, secure notes — plus a Samsung-Secure-Folder-style vault for files, photos, and videos.

👤

Hardware-backed unlock

Open with Face ID / Touch ID, gated by the device's Secure Enclave. Auto-locks the moment you look away.

📴

Yours, offline

Works fully offline on your device. No account required, no telemetry, nothing leaves your phone.

The zero-knowledge promise

Your data is encrypted with XChaCha20-Poly1305, with keys derived from your master password via Argon2id and protected by your device's secure hardware. A printed Recovery Kit is the only backdoor — and it's yours alone.
