Privacy policy

As of September 2026. The German version is legally binding.

1. At a glance

This website is deliberately lean: it sets no cookies, usesno tracking and no analytics tools, and does not load any third-party content (fonts, scripts and images are served from the own server). Personal data is only processed where technically necessary to deliver the website or when you contact me.

2. Controller

3. Hosting and server log files

The website is hosted by STRATO AG, Otto-Ostrowski-Straße 7, 10249 Berlin, Germany. When you visit the website, the web server automatically processes information transmitted by your browser (server log files): IP address, date and time of the request, requested page or file, amount of data transferred, referrer URL, browser type and version, and operating system.

This processing is necessary to deliver the website and to ensure its security and stability. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure and error-free operation). STRATO deletes or anonymises the log files after a short period. A data processing agreement pursuant to Art. 28 GDPR is in place with STRATO.

4. Encryption

The website is served exclusively via HTTPS (TLS), so transmitted data cannot be read by third parties.

5. Local storage of your colour scheme

If you explicitly choose a light or dark colour scheme using the switch in the header, this setting is stored in your browser's local storage so it persists on your next visit. The information never leaves your device and is not transmitted to me. Storing it is strictly necessary for the service you requested (Section 25(2) no. 2 TDDDG). You can delete it at any time by choosing "System" again or clearing the site data in your browser.

6. Contacting me

If you contact me by e-mail or phone, I process the information you provide (e.g. name, e-mail address, phone number, content of your request) to handle your inquiry. The legal basis is Art. 6(1)(b) GDPR where your inquiry relates to a contract or pre-contractual measures, otherwise Art. 6(1)(f) GDPR. The data is deleted once it is no longer required and no statutory retention obligations apply.

7. Links to external services

The website links to external services (e.g. LinkedIn, Xing, Credly and partner websites). No content from these providers is embedded; data is only transferred to them when you click a link. Their own privacy policies apply to any processing there.

8. Your rights

Within the statutory framework, you have the right to

• access your stored data (Art. 15 GDPR),
• rectification of inaccurate data (Art. 16 GDPR),
• erasure (Art. 17 GDPR) and restriction of processing (Art. 18 GDPR),
• data portability (Art. 20 GDPR),
• object to processing based on Art. 6(1)(f) GDPR (Art. 21 GDPR).

You may also lodge a complaint with a data protection supervisory authority, e.g. the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW), Kavalleriestraße 2–4, 40213 Düsseldorf, Germany.
