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.
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 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.
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.
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.
