Hosting
This website is delivered by Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA). When you visit a page, Cloudflare processes technically necessary data such as your IP address, date and time, the requested page, referrer and browser type in order to deliver the page and protect it against attacks. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure and reliable operation). A data processing agreement is in place with Cloudflare, which is certified under the EU-US Data Privacy Framework.
Cookies
This website sets no cookies for visitors and stores no information on your device, so no cookie banner is needed. A strictly necessary session cookie is only set when the site owner signs in to the editing area (§ 25(2) TDDDG).
Analytics
To count page views anonymously, this website uses Umami and Cloudflare Web Analytics. Both work without cookies and without cross-site tracking; no profiles are created and no IP addresses are stored. Recorded data include the page visited, referrer, browser, operating system and country. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in privacy-friendly audience measurement).
Fonts
All fonts are served from this website. No connection is made to third-party servers such as Google Fonts.
Contact by email
If you send me an email, I process your details only to handle your enquiry (Art. 6(1)(f) GDPR) and delete them once they are no longer needed for that purpose.
Your rights
You have the right to access, rectification, erasure and restriction of processing, to data portability, and to object to processing based on Art. 6(1)(f) GDPR. You may also lodge a complaint with a data protection supervisory authority.
