While you are on this site: a cookie is added, and various scripts can collect some non personal information about you, such as the part of world you're from, the pages you visit, the browser you're using, and how long you stay on each page. This is done to help understand where the traffic is coming from and what interests people. Beyond that, I know nothing about you, nor any personal info, unless you give it to me.
While you use this site and give me any information (such as you fill out a form with personally identifiable info, etc): I will never disclose it to anyone else unless I am forced to (such as by legal court order), or to process what you've done from a program I made (filled out a contact form so I can reply to you, etc). Almost every site in existence has done this since the internet was invented. If you don't like that, then leave. It's not like I know your name and exact location, unless you tell me.
