The web server hosting this site keeps a record of what accesses it, that is an IP address and a user agent string together with a timestamp.
According to the GDPR this is personal data. It is, however, standard practice to do so on all servers; it helps to identify cracking attempts and other attacks.
Apart from that we do not store any information about our visitors.
We also do not store any sort of internet cookies on our visitor's machines, however broadly you define that term.
