That is crazy !!! Unsaved documents are automatically saved (encrypted by keys that Apple knows) to iCloud !!! The feature is that one can transparently edit drafts on any Apple device, without worrying about saving it or moving it around. The problem is that this bypasses secure end-to-end encryption, because drafts (not yet encrypted to recepients) are being insecurely saved.
Yes I read about this, this is really bad stuff. I try to stay away from "cloud services" as much as possible.
