How it works

From install to total control, in a few minutes

Set your passphrases, pick a disguise, and start storing what matters. Everything stays on your device — and you stay protected even when someone is watching over your shoulder.

The journey

Five steps, start to finish

No accounts, no servers, no setup wizard that phones home. You hold every key.

1

Install and set your passphrases

On first launch you create a Master passphrase, and optionally a separate Decoy passphrase and a duress PIN. They are generated and stored only on your device — never uploaded, never recoverable by us.

2

Choose a disguise

Optionally mask the app as a working calculator or a plain notes app. To anyone who picks up your phone, it looks like an everyday utility — not a vault.

3

Add your data

Store private notes, photos and videos, documents, and asset records. Each item is encrypted on-device before it ever touches storage.

4

Lock and carry

Close the app and your vault locks automatically. Your data travels with you, fully offline, with nothing left exposed in plain text.

5

Under duress

If you are forced to unlock, open the Decoy vault to reveal believable-but-harmless content — or enter your duress PIN to crypto-erase the keys instantly, rendering protected data unrecoverable.

Three vaults, one app

Different keys open different worlds

Each passphrase unlocks its own isolated vault. Without the right key, there is nothing to see — and nothing to prove exists.

Master vault

Your real data. Unlocked only by your Master passphrase, encrypted on-device, and never visible from any other entry point.

Decoy vault

A believable, separate vault with its own passphrase. Open it safely if someone demands access — they see ordinary content and never reach your real data.

Stealth vault

A hidden third vault, opened by its own key. By design there is no button, badge, or trace to suggest it exists, so no one can prove there is more to find.

Camouflage

Hide in plain sight

When the app is disguised as a calculator, your entry point is the calculator itself. Type your code where a sum would go, press equals, and the vault opens. To everyone else, it just adds numbers.

  • The disguise is a fully usable calculator or notes app
  • Your code unlocks the vault — no obvious login screen
  • Camouflage is optional and you can turn it off any time

A switch you hope never to use

Set a duress PIN and keep it ready. Entering it destroys the encryption keys for your protected vaults immediately. Without those keys, the encrypted data cannot be decrypted — by you or anyone else.

  • Triggered by a PIN you choose, not a hidden menu
  • Keys are erased on-device, with no server to undo it
  • The action is permanent, so keep your own backups
