In our Q platform, we specifically upload only the hashes of the address book. There is absolutely no need to have the actual email or phone number of people in order to find "who is on the service". However, when you INVITE people, we specifically download the full email address because we send them an invitation ourselves.
This is just one out of 100 things that our platform does while solving the usual stuff of apps: user signups, importing address books, invites, etc. However, we applied for a patent on some of the stuff we do. Even though I personally don't like patents, it's the thing to do in the current environment. Going to write a blog post about it soon.
