The FBI has successfully extracted deleted Signal messages from a suspect's iPhone via notification storage, the place where all your notifications are stored for up to one month.
Notification storage stores data from all messaging apps, it's a big flaw in iOS. But there's a way to turn it off...
Go to iOS Settings → Notifications → [App Name] → Show Previews and set it to Never.
You can also do this globally under Settings → Notifications → Show Previews → Never
Also don't forget to turn on Advanced Data Protection in your iCloud settings if you really want to OWN your data.
Just to be sure, also disable the function in Signal. In Signal → Settings → Notifications → set “Notification Content” to No Name or Content.
Signal doesn’t send the message content to Apple servers. Instead, it’s decrypted on your device by Signal and stored in the notifications storage. Disabling one of the two preview settings, either in iOS or in Signal, should stop this from happening.
