This Cookie Policy informs you about how and for what purposes cookies and comparable technologies are used on our website. It supplements our Privacy Policy, which contains detailed information on the processing of your personal data.
Cookies are small text files that are stored in your browser’s memory or on your device when you visit our website. They make it possible to recognise your browser on a return visit, to save settings and to provide certain functions. In addition to classic cookies, we use comparable technologies, in particular your browser’s Local Storage and Session Storage as well as third-party tracking pixels.
The following legal bases apply to the use of cookies and comparable technologies:
Technically necessary cookies are used on the basis of Section 25 (2) No. 2 of the German TDDDG. The subsequent processing of personal data is based on Art. 6 (1) (f) GDPR (legitimate interest in operating the website).
All other cookies and technologies (statistics, marketing, external content) are set exclusively with your express consent. The legal basis is Section 25 (1) TDDDG in conjunction with Art. 6 (1) (a) GDPR.
Your consent is voluntary. You can withdraw it at any time with effect for the future. The lawfulness of the processing carried out up to the point of withdrawal remains unaffected.
These cookies are required for the operation of the website. They enable basic functions such as page navigation, secure areas, language settings and saving your cookie preferences. The website cannot function properly without these cookies. They are set without consent.
These cookies help us understand how visitors interact with the website by collecting and evaluating information. We use these insights to improve our services. For this purpose we use Google Analytics 4 (see section 5.1 for details). These cookies are only set with your consent.
Marketing cookies are used to recognise visitors across websites and devices. On this basis, we can show you relevant advertising and measure the effectiveness of our advertising campaigns. These cookies are only set with your consent. We do not currently use any marketing cookies.
This category covers third-party content embedded on our website (e.g. interactive maps, videos, chat functions). These providers set their own cookies and comparable technologies. Such content is only loaded after you have given your consent.
The following overview shows the cookies and comparable technologies used on our website, grouped by category, with details of the provider, purpose and storage period. We update this overview whenever our use of cookies changes.
| Cookie | Provider | Purpose | Category | Storage period |
|---|---|---|---|---|
| cmplz_functional, cmplz_statistics, cmplz_marketing, cmplz_preferences, cmplz_policy_id, cmplz_banner-status | Complianz (local, no data transfer) | Stores your cookie consent per category | Essential | 365 days |
| pll_language | Polylang (local) | Stores your language selection | Essential | 1 year |
| wordpress_test_cookie | WordPress (local) | Checks whether your browser accepts cookies | Essential | Session |
| _ga | Google Analytics | Distinguishes website visitors (pseudonymous ID) | Statistics — only after consent | 2 years |
| _ga_* | Google Analytics | Maintains the session state | Statistics — only after consent | 2 years |
Detailed information on the processing of personal data by the individual services can be found in our Privacy Policy.
For audience measurement we use Google Analytics 4 (“GA4”), a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, integrated via Google Tag Manager. The following applies:
Only with consent: GA4 is only activated after you have agreed to the “Statistics” category in the cookie banner. Without consent, no analytics data is transmitted to Google — not even so-called “cookieless pings”. Technically, we ensure this via Google Consent Mode v2.
IP anonymisation: GA4 does not store IP addresses; the IP address is only processed briefly for coarse location determination and is not logged.
Storage period: Analytics data is automatically deleted by Google after 14 months.
No sharing with other Google services: The sharing of measurement data with other Google products and services is deactivated. A data processing agreement is in place with Google.
You can change your cookie settings and withdraw consent you have given at any time with effect for the future — withdrawing consent is as easy as giving it. To do so, click the following link:

When certain cookies and tracking technologies are used, data is transferred to countries outside the European Union and the European Economic Area, in particular to the USA (e.g. to Google LLC in the context of Google Analytics). For providers based in the USA that are certified under the EU-US Data Privacy Framework — this includes Google — an adequacy decision of the EU Commission dated 10 July 2023 justifies the transfer.
For non-certified providers, data is transferred on the basis of EU standard contractual clauses pursuant to Art. 46 (2) (c) GDPR and your express consent pursuant to Art. 49 (1) (a) GDPR. A level of protection equivalent to that of the EU cannot be guaranteed in these cases. Detailed information on the respective providers and third-country transfers can be found in our Privacy Policy.
To manage cookies and your consents, we use the WordPress plugin Complianz, provided by Complianz B.V., Kalmarweg 14-5, 9723 JG Groningen, Netherlands. Complianz stores your consent settings in technically necessary cookies (cmplz_*) directly in your browser; your consent data is not transmitted to the provider.
These cookies are set without consent on the basis of Section 25 (2) No. 2 TDDDG. The legal basis for the subsequent processing of personal data is Art. 6 (1) (c) GDPR (legal obligation to document consent) and Art. 6 (1) (f) GDPR (legitimate interest in legally compliant consent management).
