Hosting
This website is served through GitHub Pages, a service of GitHub, Inc., 88 Colin P. Kelly Jr. Street, San Francisco, CA 94107, USA. GitHub acts as our processor (Art. 28 GDPR) under the GitHub Data Protection Agreement.
By its own account, GitHub logs and stores your IP address for security purposes, together with the request data a web server records. The retention period is set by GitHub and is not published.
Content is delivered through the content delivery networks of GitHub's sub-processors Fastly, Inc. and Cloudflare, Inc. (both USA). The transfer to the USA rests on GitHub's certification under the EU-US Data Privacy Framework (adequacy decision under Art. 45 GDPR) and on the standard contractual clauses agreed in the GitHub Data Protection Agreement (Art. 46(2)(c) GDPR).
The legal basis is Art. 6(1)(f) GDPR: our legitimate interest in the secure and reliable operation of this website.
