We use Google Analytics, so it collects some data about you. We can't really see anything unique though.
We use Add2Any for social sharing, and it might collect some data about you. We don't collect anything though that Google Analytics doesn't already grab.
We host the tech on Amazon Web Services using CloudFront, but don't explicitly log user data for ourselves.
We don't show ads yet, but if we do we'll try to make sure they play nicely with your right to privacy.
