Features

Everyday privacy needs, inside something that looks perfectly ordinary.

Private vault

Photos, videos, audio and other files move into the app's private directory and are stored encrypted; other apps cannot read them, and you can remove them from the system gallery.

App lock

Put a 4-digit lock in front of the apps you choose. It re-locks when you leave, and home-screen badges can still show unread notifications.

Icon disguise

The name and icon on the home screen can look like a calculator or another everyday tool, so nobody notices what is inside.

Intruder photo

After repeated failed unlocks, the front camera captures an image locally so you can see who has been trying.

Built-in browser & downloader

Browse and save videos without leaving the app. Bookmarks, history and the download list stay on your device and can be cleared in one tap.

Device-to-device transfer

Send files directly between two devices on the same local network — nothing passes through a server.

Privacy by design: we cannot see your content

Reminder: because we cannot access your content, a lost passcode cannot be recovered by us. Please keep it safe and set a hint.

FAQ

Do I need an account or a subscription?

No account is required — install the app, set a 4-digit passcode and you are ready. Some advanced features may be described in-app.

What if I forget my passcode?

Your content is encrypted with your passcode and we cannot access it, so protected files cannot be restored if the passcode is lost. That is also what keeps it safe.

Are my files uploaded to the cloud?

No. Files stay on your device. Outbound connections only happen when you actively share, use the built-in browser, or transfer between devices.

Why does the home-screen icon look like a calculator?

That is the icon disguise feature, and it is intentional: it keeps the private space unobtrusive. You can change it inside the app.
