Privacy policy

Last updated: September 2026. The German version is legally binding.

Controller

In short

This website uses no tracking or analytics and loads nothing from third parties. Fonts and images are served from the same domain. The website itself sets no cookies.

Hosting and content delivery

The website is served via Cloudflare Workers, provided by Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. When you open a page, Cloudflare necessarily processes your IP address, date and time, the requested address, the referrer and browser and operating system details in order to deliver the page and protect the service against attacks. To fend off automated attacks, Cloudflare may set strictly necessary cookies. I keep no logs of my own and do not use Cloudflare's web analytics.

The legal basis is Art. 6(1)(f) GDPR; my legitimate interest is the secure, fast and reliable operation of the website. Cloudflare runs a global network, so data may also be processed outside the EU. Cloudflare, Inc. is certified under the EU-US Data Privacy Framework; Cloudflare's data processing terms with standard contractual clauses also apply. More information: Cloudflare privacy policy.

Contact by email

If you email me, I process your details to answer your request (Art. 6(1)(b) or (f) GDPR). The data is deleted once it is no longer needed for that purpose and no statutory retention obligations apply.

External links

Links to LinkedIn and GitHub are plain links. Only when you follow one does the respective provider’s privacy policy apply.

Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on Art. 6(1)(f) GDPR (Art. 21). Just write to the email address above.

You may also lodge a complaint with a data protection authority, for example the Bavarian Data Protection Authority (BayLDA), Promenade 18, 91522 Ansbach, Germany.
