What is a Secret Chat?

Secret Chat uses end-to-end encryption which offers greater levels of privacy and bolsters security of user information. All messages are encrypted with a key held only by the participants of the chat so no third parties can access secret chat content without accessing the device itself. Secret Chat is currently available for 1:1 and group chatrooms. 

In a secret chatrooom, features including free calling, polls, events and chatroom album are currently not available.
