WhatsApp is testing self-deleting messages that vanish after 7 days
WhatsApp is testing a self-deleting message feature called “disappearing messages.”
The feature lets users choose for their messages to self-destruct seven days after being sent or received.
A WhatsApp spokesperson told Business Insider the company hopes to roll out disappearing messages worldwide soon.
Users will be able to toggle disappearing messages on or off for each individual conversation.

A WhatsApp spokeswoman confirmed to Business Insider that a small number of users are testing the feature, which the encrypted-messaging service hopes to roll out globally soon.

In some circumstances, specific messages won’t entirely vanish, per WhatsApp’s FAQ. If you reply to a message that’s due to disappear, the quoted version of that message will remain after the seven-day limit. The same applies to forwarded messages.
