Apps With Disappearing Messages or Posts - What UK Parents Should Know
Messages, photos or posts delete themselves automatically after they are seen or after a set time.
Why it matters
Disappearing content can make children feel safe sharing things they would not otherwise share, but it can still be screenshotted or recorded, and it leaves less for a parent or the police to see if something goes wrong.
What to check
Talk about screenshots: anything sent can be kept. Check whether disappearing messages are switched on by default.
