Controller: see Impressum.
Hosting
This website is hosted by Cloudflare, Inc. When you visit, Cloudflare processes technical data (IP address, browser, time of access) to deliver the page and protect it from attacks (Art. 6(1)(f) GDPR, legitimate interest in a secure and working website). Cloudflare may process data in the USA; Cloudflare is certified under the EU-U.S. Data Privacy Framework.
Analytics
We use Cloudflare Web Analytics, which does not set cookies or store data on your device and does not track you across sites. It reports aggregate figures such as page views and referrers (Art. 6(1)(f) GDPR).
External links
Links to providers pass through a short exit page on this site (/out/…) so that Cloudflare Web Analytics can count, without cookies, how many readers continue to a provider. Nothing else is stored. Once you reach the other website, its privacy policy applies.
What this site does not do
No contact forms, comments, accounts or newsletter; no embedded videos, maps, social buttons or external fonts (text uses your device's own fonts); no advertising and no affiliate tracking.
Cookies
This site currently sets no cookies. If advertising is added later, we will ask for your consent first.
If you email us, we use your message only to answer it and delete it when it is no longer needed.
Your rights
Data processed by Cloudflare for delivery and security is deleted according to Cloudflare's retention periods; analytics data is aggregated and contains no profile of you.
You have the right to access, rectification, erasure, restriction, data portability and objection (Art. 15–21 GDPR), and the right to complain to a data protection supervisory authority, for example the one in your federal state.
