Disappearing messages are being rolled out globally across Android and iOS starting today, WhatsApp said. While it’s starting with a 7 day lifespan, it is already looking at playing around with the time limits.
WhatsApp Disappearing Messages Feature Rollout To Be Completed In November
Messages including Photos and Videos can now automatically deleted in 7 days if you enable this option in Whatsapp.
And just to be clear, the 7-day limit will exist regardless of whether the message gets read or not. (The disappearing message clock starts counting when the message is sent, as it does on other apps like Telegram.)
