Why KeepCipher
A custom archive format built for controlled access.
The site now presents the real product clearly: the desktop app, current downloads, Pro plans, activation flow, and support in one place.

KeepCipher shows the QR code, accepts authenticator verification, and issues recovery codes so protected archives stay usable even when the primary device is unavailable.

Generate your activation code first, use it during checkout, and then activate Pro directly inside the desktop app.
