Private

All messages are end-to-end encrypted with a military grade standard and have digital signature, so no one could read or change them, even your mobile operator or ISP.

Simple

You don't need a password to access your account. The authentication keys are stored on your device, so only you can access them. Besides that, you don't even need a username!

Fast

Cryptogram uses its own protocol optimized for speed and security. Check the delivery speed of your messages and compare it with other apps.

Auto deletion

The messages history is not stored on Cryptogram servers. All messages are destroyed if not delivered in 24 hours. Local history on the device can be configured for auto-deletion via app settings.

Server doesn't know

The chat encryption key is different for all contacts. It is only known by you and your opponent. So, even if a possible attacker had access to the server - he would be unable to read or change anything.
