Does WhatsApp encrypt the data on the device after it’s received and decrypted at your phone’s end (then stored indefinitely)? I thought the term of art was “encrypted at rest,” but “stored data encryption” makes sense to me too.
I was of the impression that Whatsapp’s messages (and its backups, photos, etc) kind of just hung around in plaintext once they reached the device.
Which would seem to be a problem should the device be stolen, or observed by other applications on the phone or a tethered device, or twiddled with sneaky hardware (e.g. [0]) that might use physical means to access the device’s file system.
Although as I understand it, the privacy claims are kind of window dressing anyway, and Meta has been more than willing to share plenty of WhatsApp’s data with all and sundry… even before AI-in-the-same-search-bar came along [1]

The operating system (Android/iOS) encrypts everything anyway. Why would you double that? More to the point, do any of the other "safe" apps, like iMessage, do that?
