RE: @josephcox@infosec.exchange
To stop leaking your Signal messages:
Signal > Settings > Notifications > Notification Content > Show > “Name only” or “No name or content”
iOS and Android notifications all go through Apple and Google’s servers respectively and are not end to end encrypted. The feds have known and used this for years now.
Edit: That last bit doesn’t affect Signal, my bad. The settings change does still protect from the on-device notification DB storing message preview. See this reply for more info
