> Or does everybody already understand that auto-deletion is best-effort and shouldn't be treated as on par with the strength of assurance that Signal provides for privacy? No, but this is what we should teach. Even "best effort" is misleading. Auto-deletion should be considered a UX feature that only affects your own experience, not those you talk to. That said, in a high trust relation you can assume that auto-deletion is best effort, same as with your own devices. It should be seen as "this is a hint that helps your peer to delete messages, so that they don't stick around for everyone's sake".
