Android nowadays only ships with Gmail app. It can do generic IMAP but it's never been clear to me if the process is entirely on-device. I'd rather not keep Google in the loop. That said there are some generic mail clients for Android. Not many are good, but they're out there. K-9 has recently received some love again.
