Liability Disclaimer: While the content of this website has been put together with great care and reflects our current knowledge, it is provided for information purposes without being legally binding, unless the disclosure of this information is required by law (e.g. the legal information, the privacy policy, terms and conditions or mandatory instructions for consumers). We reserve the right to modify or delete the content, whether in full or in part, provided this does not affect our existing contractual obligations. All website content is subject to change and non-binding.
Link Disclaimer: We do not accept any responsibility for or endorse the content of external websites we link to, whether directly or indirectly. The providers of the linked websites are solely responsible for all content presented on their websites and in particular, any damage resulting from the use of the information offered on their websites.
Copyrights and Trademarks: All contents presented on this website, such as texts, photographs, graphics, brands and trademarks are protected by the respective intellectual property rights (copyrights, trademark rights).

Privacy Policy
Controller — Personal data on this website is processed by the provider named above (see “Provider”).
Hosting — This website is hosted on our own server. The underlying infrastructure (data center and physical server) is provided by Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. The server is located in Germany (EU). The web server does not keep access logs: no IP addresses or request data are written to log files. Your IP address is processed transiently by the server and network stack only to deliver the requested pages, based on our legitimate interest in operating the site securely (Art. 6(1)(f) GDPR). An order-processing agreement (AVV, Art. 28 GDPR) is in place with the infrastructure provider.
Contacting us — If you contact us by email, the data you provide is processed solely to handle your enquiry (Art. 6(1)(b)/(f) GDPR) and deleted once it is resolved, subject to statutory retention periods.
External links — This site links to third-party services (Calendly, LinkedIn, Lichess). No data is sent to them when you load this site — only once you click a link and leave. Their own privacy policies then apply; Calendly in particular is US-based.
Your rights — You have the rights to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), data portability (Art. 20), and objection (Art. 21). Where processing relies on consent, you may withdraw it at any time. You may also lodge a complaint with a supervisory authority; the one responsible for our location is the LDI NRW (Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen).
Encryption — All connections to this site use TLS/SSL.
