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, what interests people and so on. Beyond that I know nothing about you, nor any personal identifiable info, unless you give it to me.
For example: while you use this site or give me any information on it (such as you fill out a form with personally identifiable info, like your name, and email, etc... And technically, you could fill out fake info if you wanted), or if you interact with my website... Then the form info you filled out on my site will go to me, but some other non-identifiable info will go to companies like Google. If / when that happens depending on whether or not you're using an ad blocker (which you should), then I will never disclose any of that info 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 (such as you filled out a contact form so I can reply to you, and it sent some non-identifiable info to google, etc).
Almost every website 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.
