This site sets no cookies, and it runs no code of its own in your browser.
The one script on it is Cloudflare's Web Analytics beacon, which counts visits in aggregate: which pages were viewed, which site sent the visitor, the visitor's country, browser and type of device, and how fast the pages loaded. It uses no cookies and no local storage, and it doesn't follow you from site to site. I use it on purpose, to see whether anyone reads this.
Cloudflare serves the site and keeps the request logs any web server keeps, such as IP addresses, under its own privacy policy.
There's no contact form and no account here, so the site collects nothing else.
