Is this site a part of Google?
No! This website is a fan made website that I decided to make as I wanted a pretty way of linking to my account as vanity URL's are not rolled out to all as of yet.
What data of mine do you collect?
This site uses the Google+ API to login and users always have full control of their accounts. We have even allowed users to delete all user data from the website should they want to!
If I want to contribute or give some feedback?
I'm always greatful for any help or constructive critisism! And help is even better! You can email me directly here: firstname.lastname@example.org
