Secure messenger SafeUM Features

Encrypted chats and calls

Secure messenger SafeUM encrypts text messages, voice calls, video calls, group chats, and shared files. You can verify a contact’s encryption keys with a QR code. Each message uses a new secret key, and a digital signature helps confirm that messages are intact and sent by the right person.

Account setup and control

After installing the Secure messenger SafeUM APK, you can register with only a login and password, no SIM card required. You may run up to three accounts on one device and set three access levels protected by PIN codes. Account access controls and authorization history make it easier to review who signed in and when.

Privacy options in chats

• Disable chat history on both sides at the same time
• Limit how many recent messages are shown in a chat
• Avoid storing local data on the device for added privacy
• Receive alerts about possible account hacking attempts
• Reduce exposure of personal information on public networks

Calls and number policy

You can place free encrypted audio and video calls within the SafeUM network. A telephone number in the +3712 format may be assigned at registration. If there is no recharge and no call activity for 14 days and the balance is zero, the number can be withdrawn, and recovery is not possible. This does not affect in-network chats and calls. A positive balance keeps the number active.
