This website does not intend to track its users, although it is difficult to keep usage 100% anonymous:

To resolve the domain name into an IP address, Cloudflare registers the receipt of a request from your IP address. However, they state that they themselves adhere to a strict privacy policy.

When you send a donation, PayPal and your bank will have a record of it.

Also the web server generates log files containing users’ IP addresses. These log files are rotated daily. IP addresses are truncated during log rotation. The log files are deleted after no more than 7 days, unless further retention is required in an individual case to investigate a specific security incident.

If you send an email to the webmaster, he receives your email address—but it will never be passed on.

Please get in touch if you have any concerns.
