Oh, I was originally confused about this because I had thought the push notifications were end-to-end encrypted, so they couldn't be cached in readable form by the push notification service, and only decrypted by the app on device upon receiving the notification. But it seems like after the notification was decrypted by the app and shown to the user using OS APIs, the notification text was was then stored by the OS in some kind of notification history DB locally on the device?

Much of the metadata is plaintext, in both Apple and Google's Push Notification architecture.

		My understanding is that in Signal's implementation of push notifications the message text is end-to-end encrypted by Signal and decrypted on device by the Signal app. The decryption is not handled by the OS's push notification system.
