How it works

Three steps and you're done

No technical know-how needed.

01

Pick a password

This is the only key to your vault. If you forget it, it's gone — there's no reset.

02

Drop in your files

Drag anything in. Each file gets locked the moment it lands.

03

Save a backup

Download your vault as one file and open it on any device with your password.

Features

Everything you need. Nothing you don't.

Only you can open your files

Everything is locked on your device before it gets saved. We can't read them, period.

Locks itself

Leave it alone for five minutes and it closes on its own.

Block files by country

Stop a file from opening in places you don't take it.

Take it anywhere

Your backup opens on any device. All you need is the file and your password.

Stay tidy

Folders and search make a big vault easy to dig through.
