2. Hosting and server log files

This website is hosted by Mittwald CM Service GmbH & Co. KG in Germany. All data is processed on servers located in Germany.

When you visit this website, the web server automatically collects technical information in so called server log files.

This data is technically necessary to deliver the website to you, to ensure its stability and security, and to detect and prevent misuse.

The legal basis for this processing is Art. 6 (1) (f) GDPR, our legitimate interest in providing and securing this website. Log files are deleted or anonymised after a short period unless they are needed to investigate a specific security incident.

If you contact us by email, we process the data you provide (your email address and the content of your message) solely to handle your request. The legal basis is Art. 6 (1) (f) GDPR, or Art. 6 (1) (b) GDPR if your request relates to a contract. We delete this data once your request has been fully handled, unless statutory retention obligations apply.

You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the EU member state of your habitual residence, your place of work or the place of the alleged infringement. The authority responsible for us is the Hamburg Commissioner for Data Protection and Freedom of Information (Der Hamburgische Beauftragte für Datenschutz und Informationsfreiheit).
