If you turn off notification history on Android, should be enough to avoid such “attacks”. Hiding sensitive content inside notifications only hides it in the lock screen. If your OS keeps a clear log of them, it’s useless.
Edit: didn’t know Signal actually has settings to hide their own notifications. I was thinking about Android’s “hide sensitive content” setting.

Notifications go through FireBase Cloud Messaging (FCM) on Android. They bounce off a Google server. Even from local, on-device apps.
Same with iOS.
They can read and store every one of them, and you don’t control the encryption keys.
But they only instruct Signal to wake up and download whatever is waiting. They don’t contain the message contents.
