5. Audience measurement with Dendree Analytics and Google Analytics
If you allow the category "Statistics" in the cookie banner, this website measures its audience with Dendree Analytics, software we run ourselves (stats.dendree.de). This data is not passed on to third parties.
It records the page visited, the page title, the referring website, UTM parameters, language and screen size, as well as browser, operating system and device type; country, region and city are derived from the IP address. Neither the IP address nor the full user agent is stored. To count visits, a one-way hash is formed from the website, IP address, user agent and a salt that changes daily; on the next day you count as a new visitor.
Dendree Analytics sets no cookies and stores nothing on your device.
With the same consent, this website also uses Google Analytics 4, a web analytics service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Analytics sets the cookies _ga and _ga_* (kept for up to 2 years) to recognize returning visits and sends information about pages viewed, clicks and downloads, device, browser and approximate location to Google. Google Analytics 4 does not store IP addresses. Data may also be transferred to Google LLC in the USA, which is certified under the EU-US Data Privacy Framework. More information: policies.google.com/privacy
The legal basis for both services is your consent (Art. 6 (1)(a) GDPR, Section 25 (1) TDDDG). You can withdraw it at any time via "Change cookie settings" in the cookie policy; the Google Analytics cookies are then deleted.
6. YouTube Videos
This website embeds content from YouTube. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.
When you visit a page with an embedded video, a connection to YouTube's servers is established. This transmits which pages you visit. If you are logged into your YouTube account, YouTube can associate your browsing behavior directly with you. Legal basis: Art. 6 (1)(a) GDPR
