Actually, it might be just me, but I find this incredibly annoying. I use swift-text on android and while usually when I start typing my email address I get a suggestion for my long email address, but when type=email I don't get a suggestion, just a little @ key at the bottom. Might not be this way for all keyboards though. Just a thought.
Edit: Oh and great job on the app! I think this is an awesome idea and if some of the privacy and longevity concerns were addressed, I would use it all the time!
