Log-in issues and no support

Ive downloaded the iOS app and logged in using
Facebook. But if I want to log in on the website there is not way to do that with Facebook and for the life of me I cannot find away to see my email address & password for your guidebook account on my app. How can I use & sync my guidebooks across platforms when I cannot log in?
BIG Suggestion:
SUPPORT! They have no email addresses, no FAQ and now support in app or on your website.
