The basics
Multiple vaults
One app, as many vaults as you like — each its own encrypted space, and nothing reveals the others.
A different PIN opens a different vault.
Each vault is a separate encrypted space. Lock, enter another secret, and you’re somewhere else entirely — nothing links the two, and neither points to the other.
What actually keeps it safe
Your recovery phrase guards the vault
PIN · passphrase · pattern
A fast way in on this device.

The true key — with an encrypted backup, it restores the vault on a new phone.
No one can count your vaults
There’s no list anywhere — not even in the app. Until a secret unlocks one, nothing shows a vault exists. Any vault can stay hidden.
Under the hood
Everything is encrypted on your device with AES‑256‑GCM before it’s written to storage. Your secret is stretched with Argon2id and bound to the device’s Secure Enclave — so the vault key can only be derived on this phone, with your secret.
Your vault is waiting.
