For those interested in maximum privacy, Post Office Messenger offers Secret Chats. Secret Chat messages can be programmed to self-destruct automatically from both participating devices. This way you can send all types of disappearing content — messages, photos, videos and even files. Secret Chats use end-to-end encryption to ensure that a message can only be read by its intended recipient.
