The only cookie this site uses is from google analytics (alphabet). It is used to track site visits, return visits, how people are finding my site, etc.
If you use the contact form to reach out to me, the information you entered is stored for 20 days, but you send me an email with your email and I will send you a link that you can use to erase your data immediately.
If you sign up for my newsletter, all that is handled through substack. You can read their privacy policy here.
