2. In short

This website is purely informational. It sets no cookies, uses no analytics or tracking and has no forms. I don't collect personal data through this site myself. The hosting provider does process technically necessary data when you visit, see section 3.

3. Hosting via GitHub Pages

This site is served by GitHub Pages, operated by GitHub Inc., 88 Colin P. Kelly Jr. Street, San Francisco, CA 94107, USA. When you visit, GitHub processes technically necessary data such as your IP address, date and time of access, the requested page, browser type and operating system, in order to deliver the site and keep the service secure.

Legal basis: Art. 6(1)(f) GDPR, based on my legitimate interest in providing the website securely and reliably. Data may be transferred to the USA. GitHub is certified under the EU-US Data Privacy Framework (adequacy decision, Art. 45 GDPR). More: https://docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement

4. Fonts

All fonts are hosted locally. No connection to Google or other font providers is made.

If you switch between light and dark themes, only that preference is saved locally in your browser (Local Storage, key “portfolio-theme”). It is not sent to me or third parties. You can delete it by clearing this website's data in your browser.

5. Links to other websites

This site links to GitHub and LinkedIn. Only when you click a link do you leave this site, and the provider's privacy policy applies.

6. Contact via email or LinkedIn

If you contact me, I process your details to reply (Art. 6(1)(b) or (f) GDPR) and delete them once they are no longer needed, unless legal retention obligations apply.

7. 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) (Art. 21). Just send me an email. You can also lodge a complaint with a supervisory authority, e.g. the State Commissioner for Data Protection and Freedom of Information of the Free Hanseatic City of Bremen, https://www.datenschutz.bremen.de
