Settings > Notifications > Notification Content > Show: "Name Only" or "No Name or Content" I've had this enabled to prevent sensitive messages from appearing in full whilst showing someone something on my phone, but I guess this is an added benefit as well.

I guess enabling Lockdown mode might avoid this particular issue too, together with a bunch of other stuff?

Why would lockdown mode prevent this? I have lockdown mode on but that doesn't automatically make my notifications private.

First, a critical setting for Signal users: "Signal’s settings include an option that prevents the actual message content from being previewed in notifications. However, it appears the defendant did not have that setting enabled, which, in turn, seemingly allowed the system to store the content in the database." Second, how can I see this notification history?

On android there are apps that let you see the history - i use NotiStar occasionally to see if i unwittingly dismissed important notifications. And i believe there are apps/settings that help you clear the history from the device. But this is a reminder that these centralized notification infrastructure (FCM and APNs) store notification content (if the app is told to send content in it - signal with option enabled wo…

On Lineage Android, i see: Settings / Notifications / Notification History.

If you drop a settings widget on your home screen, it will let you choose a specific area, including notifications.

I don't know if the output is the complete database.

> testimony in a recent trial

Court cases are the real way to audit security.

Larping about security and complaining about companies responding to court orders only gets you so far. Its way more useful to look at what actually happens in reality.

That's unfortunately less informative if you aren't already one of their subscribers.

I wonder why Apple doesn't 'just' delete the notification data associated with the app from the internal database when the user deletes the app? It seems like asking for problems to just keep old notification content around forever.

It's one of those problems where as soon as someone notices, it's crazy that no one noticed. I can't imagine this not being overhauled going forward. It's just a bad way to operate and now it's news.
