No, it is readable when it is on company servers. http://images.apple.com/privacy/docs/legal-process-guidelines-us.pdf http://images.apple.com/privacy/docs/legal-process-guideline... "iCloud is Apple’s cloud service that allows users to access their music, photos, documents, and more from all their devices. iCloud also enables subscribers to back up their iOS devices to iCloud. With the iCloud service, subscribers can set up an iCloud.com email account. iCloud email domains can be @icloud.com, @me.com and @mac.com. iCloud data is encrypted 3wherever an iCloud server is located. When third-party vendors are used to store data, Apple never gives them the keys. Apple retains the encryption keys in its U.S. data centers. The following information may be available from iCloud..." "...i. Subscriber Information ... name, physical address, email address, and telephone number ... iCloud subscriber information and connection logs with IP addresses ... Mail Logs ... Email Content ... Other iCloud Content. Photo Stream, Docs, Contacts, Calendars, Bookmarks, iOS Device Backups ... photos, documents, contacts, calendars, bookmarks ... photos and videos in the users’ camera roll, device settings, app data, iMessage, SMS, and MMS messages and voicemail. iCloud content may be provided in response to a search warrant issued upon a showing of probable cause." It is only data stored directly on devices that Apple claims it can no longer give access for. Note that a lot of data gets synced without user knowledge including working drafts of documents: http://mjtsai.com/blog/2014/10/26/yosemite-uploads-unsaved-documents-and-recent-addresses-to-icloud/ http://mjtsai.com/blog/2014/10/26/yosemite-uploads-unsaved-d...
