WhatsApp has introduced a significant update to disappearing messages that allows users to hang onto these fleeting texts for later — with a caveat.

Meta CEO Mark Zuckerberg announce the new feature, called Keep in Chat(opens in a new tab), on Facebook on Friday.

Essentially, the sender will be notified if someone wants to keep a disappearing message, the feature rolled out by WhatsApp in Nov. 2020. The sender will have final say in whether they can save it or not. If someone decides they don’t want their message saved, their decision is final and the message will disappear once the timer expires.
