Disappearing messages
Set a timer on a thread and messages auto-delete after it. Both sides know it's on; nobody can save them quietly.
What it is
Disappearing messages are DMs that auto-delete after a timer you set — 24 hours, 7 days, or 30 days. Both sides see a small clock icon on the thread so it's never a secret that the timer's on, and screenshots trigger an in-thread notice (we can't prevent them, but we can show they happened).
How to use it
Open a DM thread. Tap the info icon in the top-right, then Disappearing messages.
Pick a duration: 24h, 7d, 30d, or Off. The timer applies to new messages from that point on; older messages stay as-is.
Both people see a small banner saying the timer changed. To turn it off, repeat the steps and choose Off.
Why it matters
Most chat history isn't worth keeping forever — it's just a tax on storage and a leak waiting to happen. Disappearing messages give you a quiet default for low-stakes threads. We surface the timer to both sides on purpose; secret expiry would be a trust nightmare.
