The privacy policy for this site is very simple, should you register with your social credentials or a separate account:
Your data will never be used for any commercial end. The site will never ask you for anything more than your email (for user login purposes) and what you are ready to disclose out of your own free will.
Google Analytics is being used and your IP-adress is therefor logged, but solely for site analysis purposes, never for commercial gain since this is a privately operated website. Not a company.
However, since this is a WordPress based website which makes use of JetPack, their terms/conditions can be found here.
