Disappearing messages on WhatsApp: After weeks of testing, WhatsApp finally launched on 5th Nov the long-awaited feature of Disappearing messages. Now you can send self-destructive messages and media that disappear after a week.
The new feature is similar to that of secret Facebook Messenger conversations , but a little more restricted. You need to activate it manually. When connected, it applies to all new messages exchanged between you and a contact until the option is turned off.
