2. Principle of data minimisation

This website is built so that as little personal data as possible is created. It sets no cookies, uses no analytics or tracking services (such as Google Analytics) and loads no external content, fonts or scripts from third parties. Search also runs entirely in the browser.

3. Server log files

When you access the website, processing takes place on my own server in Germany.

  • No access logs are kept. Which pages are visited by which visitors is not logged.
  • Only in the event of a technical fault can an error log be written. It may contain the IP address, the time and the requested URL. This data is used solely to fix the fault, is not analysed and is not combined with any other data.

The legal basis for processing is Art. 6(1)(f) GDPR (legitimate interest in the secure and stable operation of the website).

The site offers a light/dark mode toggle. Your selection is stored exclusively in the local browser storage (localStorage) of your device and never leaves it. This is not a cookie and no data is transmitted to the server.

5. No transfer to third parties

No third-party services are embedded (no CDNs, no fonts, no embedded media). Accordingly, no data is transmitted to third parties when visiting this site, and there is no transfer to third countries.

6. Contact by email

If you email me at the address above, I process your email address, your name (if you provide it) and the content of the message in order to answer your request.

The legal basis is Art. 6(1)(b) GDPR where the request aims at entering into or performing a contract, otherwise Art. 6(1)(f) GDPR (legitimate interest in handling contact requests). The data is deleted once it is no longer needed to handle the request and no statutory retention obligations apply.
