Set and manage disappearing messages

Use disappearing messages to keep your message history tidy. The message will disappear from your devices after the timer has elapsed. This is not for situations where your contact is your adversary — after all, if someone who receives a disappearing message really wants a record of it, they can always use another camera to take a photo of the screen before the message disappears.

• Disappearing messages can be managed by anyone in the chat.
• The setting applies to any new messaging after the timer has been set or modified.
• Changes to the timer will sync with your linked devices.

What does a disappearing message look like? 

 Each and every disappearing message will have a timer countdown icon that is visible at the bottom of the message bubble.

When does the timer start?

• For a sent disappearing message, the timer starts after you've sent it. This is not a delivery receipt or read receipt.
• For a received disappearing message, the timer starts after you've read it.

What happens when the disappearing message timer reaches the end?

The message is deleted from disk.
