Depending on your Facebook settings we would see your email address and basic information such as name, age & gender. You provide these basic items to us as part of our own sign up process even if you do not use Facebook. If any of your friends are using PnP then we will know this too. We do NOT see any of your other friends and we do not and cannot contact anyone who is not a PnP user. So, in short, signing up with Facebook is completely safe.
