2. Visiting the website (server log files)

When you visit this website, the web server automatically stores information that your browser transmits: IP address, date and time of access, page requested, amount of data transferred, status code, browser and system information, and the previously visited page. This data is required to deliver the website and to keep it stable and secure (Art. 6 (1) (f) GDPR).

Based on the language setting your browser sends, the homepage automatically shows the German or English version. Nothing is stored for this.

The log files are deleted automatically after 14 days. To protect against attacks, IP addresses from which repeated abusive requests originate are temporarily blocked; the related security logs are deleted after one month at the latest.

3. No cookies, no tracking

This website does not set any cookies and does not use any analytics or advertising services. No third-party content is embedded: fonts, images and all other files are loaded exclusively from this server.

4. Contact by email or phone

If you contact me by email or phone, I process your details in order to answer your enquiry (Art. 6 (1) (b) GDPR for enquiries about a possible assignment, otherwise Art. 6 (1) (f) GDPR). The data is deleted as soon as it is no longer needed for this purpose and no statutory retention obligations apply.

5. Links to other websites

The links to LinkedIn, XING and GitHub are simple links. Only when you click such a link are you taken to the website of the respective provider, where its privacy policy applies.

6. Hosting

This website runs on a rented server from IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. IONOS processes the data on my behalf on the basis of a data processing agreement pursuant to Art. 28 GDPR. The data is stored in Germany.

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 (Art. 21 GDPR). You can also lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information Baden-Württemberg.
