Security is above anything else!

All data are encrypted with the original closed technology.

LockBlock allows to exchange text, voice, video messages, as well as photo, video and audio files in two encrypted modes.
You can select a preferable mode for each speaker:
  • normal mode of communication, including storage of chat history and content in the phone and synchronization between devices.
  • one-time private conversation in p2p format.
Without registration, storage of subscribers content and personal data on the servers. No record will prove your conversation has ever taken place.

Protection technology LockBlock is based on the TLS cryptographic protocol ( )
