Feature
Keep it. Or let your copy go.
Keep a copy, or let yours expire on this device.

Delivered messages stay on your phone until you delete them. Turn on disappearing for a send if you want your local copy to expire.
The relay already drops ciphertext after delivery or hold expiry. Disappearing is about what remains on the device.
- You set disappearing per send
- Server hold ends after delivery
- Local copies you control
