On Android, if you allow it to backup to your Google cloud storage, it will say the backups are encrypted. That was my experience when I set it up a few weeks ago.

Exactly who has the ability to decrypt the backup is not totally clear.

It may be a different situation for non-Android users, Android users who are not signed in with a Google account, Android users who are not using Google Play Services, etc.

    You can explore your Google Cloud's Application Storage part via Rsync, AFAIK. So you can see whether your backups are encrypted or not.

    I remember that you had to extract at least two keys from the android device to be able to read "on-device" chat storage in the days of yore, so the tech is there.

    If you don't have the keys' copies in the Google Drive side, we can say that they are at least "superficially" encrypted.
