To help the site run and to be maintained, it has Google Adsense. Google controls what information it captures about you, and you control what it can capture about you depending on what you agree to in the pop-up, or you completely avoid it by using an adblocker.
I personally do not capture any data or send it off to third parties. The site does what any site does and captures data which is used for purposes of anti-spam server-side, but it doesn’t send that data to anyone else.
I do not have any data to ‘delete’ about you, I’m also not a business.
Enjoy the blog.
