How it works

Three steps. No learning curve.

If you can drag and drop a file, you can encrypt it.

01Create a vault

Pick a size and a password. Your vault appears in Windows as a normal drive letter.

02Drag files in

Copy, paste, edit and save exactly as you always do. Everything inside is encrypted automatically.

03Lock it

One click and the vault vanishes from view. Without the password, the data is unreadable scramble.
