WhatsApp will now let people hang on to temporary messages - but it will alert the sender and give them the power to make a decision on the fate of the message. The disappearing messages function means messages automatically delete after 24 hours, seven days, or 90 days. "We believe if you've sent the message, it's your choice whether others in the chat can keep it for later," WhatsApp said in a statement.
