Cryptographic messenger SafeUM is the confidentiality of communication.
Encrypted chat eliminates information leaks. Every written or said word is encrypted.
Audio and video calls in SafeUM are done by P2P technology: it is impossible to intercept data (content) - the information is sent directly between interlocutors bypassing servers.
In the messenger, in Premium Package, end-to-end encryption is used:
All the data (including speech) in Premium package is encrypted before sending from the device and decrypted on the recipient's device only.

SafeUM OUT

Use the application to call out to mobiles and landlines around the world at the most affordable rates. Please note that your phone contacts are not automatically transferred to messenger which preserves your anonymity. Only you decide who to add to your SafeUM contact list.

 

P2P calls

Call directly with no “man-in-the-middle”.
The P2P (Person to Person) technology sends your voice and video directly to your conversation partner bypassing our servers(which only connect you to another person's gadget).
Hence, your chat history is not saved anywhere in any way.

Encrypted group chat

Such features as file transfer, history disabling and the number of messages displayed on the chat screen are available in encrypted group chats. The moderator is the one, who creates a group and he is the only one, who can modify Settings and set up the security policy of the group chat. Messages and files are delivered to online and offline contacts. If one of the participants of the encrypted group chat changes the encryption keys, other participants will get the notification about it.

Enhanced encryption

Rest assured in total confidentiality of your messaging and conversations. We use modern cryptographic/data encryption algorithms never implemented in any other public product before. You generate secret encryption keys for confidential communication. They are only stored in the device RAM and are deleted during shutdown/reset. The ElGamal Elliptic Curve Cryptosystem eliminates the possibility of your data to be decrypted.

Keys verification by QR code

Security keys verification by QR code scanning allows you to check the authenticity of the interlocutor and his keys. This additional security measure excludes MITM-attack. Scan QR code to verify the key. The service is available in offline mode.

Disable history

Disable chat history saving feature if you fear that your confidential information can be disclosed to third parties or used against you. Chat history saving is disabled simultaneously on both sides. The chat history saving icon in your dialog box will show ON/OFF.

No SIM required

Sign up without a SIM card using only login and password. Security still remains at high level thanks to additional authorization parameters.

Access PIN codes

Access to application is protected by a reliable and elaborate system of PIN codes which consist of 4 to 10 characters. The first PIN provides full access to the application and all its features. The second PIN hides secret conversations and confidential data. The third PIN deactivates the account without any possible recovery. This feature is designed for emergency situations and allows you to make sure that no third parties get access to your personal information.

Anonymity

Sign up without mobile phone number using only login and password. This will keep your location secret.

HD quality voice

With modern codecs, sound in SafeUM is transmitted in the best quality even at the minimum bandwidth of the communication channel. HD quality calls provide a "presence effect", you will hear your interlocutor as if he/she is close to you.

Video calling

Make video calls between the application users with the help of modern technologies. WebRTC provides fast video streaming whereas VP8 codec allows to achieve perfect image quality. You will definitely appreciate the quality of your communication.

Multiple accounts

Use up to three accounts on one device with calls and messages coming simultaneously to all three of them. Accounts are not interconnected and can be used on different devices without restrictions and limits. Switch by a single click.

No local data

Your conversations, secret keys, call history, messages and transferred files are not saved on your data storage devices. Device loss, theft or seizure will not expose confidential information. The encrypted data is stored on our secure servers.

Security alert

Ad Free

Basic security
