Visiting the website

When your browser requests a page, the server receives technical information such as your IP address, the requested address, and the time of the request. This information is used to deliver and secure the website. Where processing is based on our legitimate interest in operating and protecting the site, Article 6(1)(f) GDPR applies. Hosting and technical service providers may process data as necessary to provide their services.

Contacting us

When you use the contact form, we receive the name, email address, subject and message you enter. We use these details to respond to your enquiry. The legal basis is Article 6(1)(b) GDPR where the enquiry concerns a contract or steps taken at your request before a contract, and otherwise Article 6(1)(f) GDPR for handling correspondence. We keep the information for as long as needed to handle the enquiry and any applicable legal retention obligations.

Cookies and consent

The website uses cookies needed for functions such as the Joomla session. CookieHint remembers your choices about optional services. Storage or access strictly necessary to provide a service you request is covered by section 25(2)(2) of the German TDDDG. For optional services, we ask for consent under section 25(1) TDDDG and, where personal data is processed, Article 6(1)(a) GDPR. You can change or withdraw your choices through the cookie icon in the lower-right corner.

Embedded maps and videos

Some pages embed YouTube videos or a Google Maps map. If you choose to load an embedded item, your browser connects to Google Ireland Limited. This may involve processing your IP address and browser information and storing or accessing information on your device. See Google’s privacy notice for details about its services and transfers outside the EEA.

Audience measurement with Google Analytics

If you enable Statistics in the cookie settings, this website uses Google Analytics 4 provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. We use page views to understand how the website is used. Google receives the page path, technical connection and browser data, and a pseudonymous cookie identifier. The measurement uses neither user IDs nor advertising features. The _ga and _ga_* statistics cookies expire after 60 days. Google Analytics retains user and event data for two months. Google may process data outside the European Economic Area. See Google’s privacy notice for more information.

The legal basis is your consent under Article 6(1)(a) GDPR and section 25(1) of the German TDDDG. You can withdraw consent for future processing at any time by disabling Statistics in Cookie Settings.

Subject to the conditions in the GDPR, you can request access, correction, erasure, restriction of processing and data portability. You may object to processing based on legitimate interests and withdraw consent at any time for future processing. You can also lodge a complaint with a supervisory authority, for example the Brandenburg data protection authority.
