For Android

Your vault, on the drive you carry with your phone

Plug the drive into your phone and open the same vault you use on your computer, or keep it in the phone’s own storage. Photos and videos that never touch your gallery or the cloud.

Coming soon to Google PlayOne-time purchase, no subscription and no in-app purchases.

On your phone

Built for the phone

  • USB-C or OTG drive

    A USB-C drive directly, or a classic one with an OTG adapter. The vault is the same one you open on Windows.

  • No drive needed, too

    A vault in the phone’s own storage, with everything else the same. If you ever want it on your computer, export it to a USB drive and it opens on Windows.

  • Built-in camera

    Take photos and record videos that are saved straight into the vault, without going through your phone’s gallery or its cloud backup.

  • “Save to Cryptnook Vault”

    From the Share menu, in your gallery or any app. What you share goes into the vault, and the original stays on your phone: deleting it is up to you.

  • Photo enhancement, on the phone

    More sharpness, light, colour or resolution, with a model that runs on the phone and works offline. It saves a new copy and leaves the original alone.

  • Compare and find duplicates

    Compare two photos to keep the good one, or look for repeats across the whole vault.

  • Fingerprint unlock

    Optional. The password is kept under the phone’s key store; if you change it, you turn fingerprint unlock on again.

  • Locks itself

    When the app goes to the background and after the idle time you choose on this phone, independent of the one on your computer.

  • No internet permission

    The app does not declare it, so it cannot connect to anything. You can see it under “App permissions” on its Google Play listing.

Enhancing a photo on the phone: clean up, fix colour, brighten, sharpen or upscale, how strong, and the note that the phone uses a lighter model than the PC.Before and after on the phone: an old sunset photo and its enhanced copy, split by a line you can drag.
Connecting the drive

This is how it opens the first time

  1. Plug in the drive

    Directly if it is USB-C, or with an OTG adapter.

  2. Choose Cryptnook Vault

    Android asks which app should open the drive. The first time, it also asks your permission for the app to use it.

  3. Type your password

    Or use your fingerprint, if you turned it on. Unplugging the drive closes the vault.

Before you buy, check your phone

You need Android 11 or later and, to use a USB drive, a phone that reads them. Almost all recent ones do, but not all: check it in two minutes.
