If this site uses an analytics tool, it will only track basic, anonymous traffic data, pages visited, general location, device type, never anything that identifies you personally. If you sign up for the newsletter, I collect your email address and nothing else, and it's used only to send that newsletter, never sold or shared with third parties.
This site doesn't sell personal data, and doesn't use it for anything beyond what's described here. If you want your email removed from the newsletter list or have any question about what's collected, reach out through the contact info on the site.
