I am going to keep this as simple as possible to understand.
I have no use for your data beyond using it for this website only. You have the ability to login to your account at any time and remove your account and all of its data.
I use Google Analytics to see which pages are getting the most attention so I can better understand what content my viewers are enjoying and want more of.
If anything is not clear, please contact us and express your concerns and I'll do my best to find a proper solution for you.
