[quotemsg=]"developers may share data with third parties so long as they are transparent with the users about how they are using the data" and that it requires privacy policies for these third-party apps to be "easily accessible to users to review before deciding whether to grant access.”[/quotemsg]
Transparent, as in one sentence buried in page 92 of the developers EULA.
[quotemsg=21338933,0,2539507]WTH, anyone knows which email company has best privacy protection?[/quotemsg]
Given their stance on privacy. My guess would be Apple with iCloud. At least as far as multinational conglomerates with free e-mail are concerned.
Otherwise it's going to be a paid e-mail host. As I recall using the online chat when setting up a domain with hostgator. I asked about them scanning through anything. The swore up and down that they don't look at anything in their customers accounts and that they specifically say so in their privacy policy. Although I didn't bother with reading that. My concern had more to do with domain ownership privacy.
I'd assume the same would be true for any Exchange host.
You could always host your own e-mail. Domain registration is cheap. Then some DNS service if you don't have a static IP. Although any e-mail you send to others will be read if it isn't encrypted.
