This is a small awareness minisite that we built to educate visitors in the simplest possible way about what behavior usually requires you to maintain a privacy policy on your site (and how we can help fixing that gap).
Why do I need a privacy policy for a personal website using basic Google analytics? (That's what your minisite suggests.) I don't have customers, only visitors, there is no contract.
Secondly GA collects personal data from your users which in most legislations means that you need to inform users about that fact (most notoriously Europe).
