I need my work emails on my mobile. They only work with Exchange/Activesync. IMAP is not an option. Is there a good, privacy respecting app for Android out there? I would like if I could use the same app for my other E-Mails which all use IMAP. I now use Gmail, but I hate the unnecessary connection with the big G. I’d also prefer not to use Outlook (mobile) because it (might) send your credentials to MS.
I can’t comment on their privacy, but I thought of Nine when I read your post. I used it back before the Outlook app supported folders. I think it was a great alternative and worked better than anything out there… Mind you, it was years ago.
Also, have you thought about using a different user profile for just work? I know you’re asking about apps but you can gain some privacy from segregation too.
