‘Disappearing’ Signal Messages Are Stored Indefinitely on Mac Hard Drives

One of Signal’s best features is that messages can be set to “self-destruct,” meaning there is no paper trail for conversations in the app. But with Signal’s default settings on a Mac, your friends’ messages appear—and live on—on the operating system’s notifications bar even if the message is set to self-destruct using Signal’s timer. These notifications include the sender’s name and the message’s content.
