- delroth 9y agoDisclaimer: I work at Google, not on cloud. I think this is just coincidence though. Apple most likely performs their own layer of encryption on top of what Google already does.

Apple doesn't want plaintext data to be accessible by anyone at Google (or any other 3rd party provider).
