@jesterchen Yeah, that’s a great point. However, here’s an article in the news today that folks are talking about. Someone deleted the signal app but the notifications were still retrievable.

No, Signal has not been hacked. However, we do recommend turning off showing Signal content in notifications because the content is stored in memory on device. Apparently, this memory can be retrieved if an attacker has physical access to an unlocked device and has the right tool.
