Encrypted messenger SafeUM is a truly secure app. We developed several encryption schemes and algorithms that provide high  cryptographic security level. When you first log in the app, you can generate Public and Private encryption keys based on the Passphrase.

A passphrase is a set of words or symbols known only to you. A passphrase is never transmitted to our servers and is not stored on the device. Be sure to remember your Passphrase, otherwise, you will never be able to get access to the history of your encrypted chat. Only the copy of your Public key is stored on our servers.

Users' information security is a primary task of secure instant messenger SafeUM, that's why we implemented a reliable method of generating security keys. When you first log in the app, you can generate encryption keys based on the Passphrase.

Only the copy of your Public key is stored on our servers, as it's needed  for authentication and verification of your interlocutor. Private key is never sent to SafeUM servers, it's located in the  RAM of your device and is erased when you reboot or turn off  your device. If your interlocutor changes his security keys, you'll  get auto notification and will be able to decide whether or not to continue talking.
