Privacy Policy

The points mentioned on this page extend the general privacy policy available at Thomas Bella > Datenschutzerklärung.

The uDomainFlag browser extension does not collect any statistical data within the extension. Sentry is used to record programming errors, with generated reports being transmitted to a server operated by
If the user of the browser extension calls up a website for the first time in the browser session, uDomainFlag calls the upstream server for general domain information. This information is stored in the cache of the browser until it expires after a few minutes.

In order to prevent attacks and server overloads, IP addresses are briefly logged and evaluated, but deleted and anonymized within 24 hours. Transmitted domain names are not connected to the requesting client and no analysis takes place here either. The data records are separated from one another and cannot be linked to one another at a later time.

Cloudflare Privacy Policy

We use Cloudflare by the company Cloudflare, Inc. (101 Townsend St., San Francisco, CA 94107, USA) on this website to enhance its speed and security. For this, Cloudflare may be using cookies and processes user data. Cloudflare, Inc. is an American company that offers a content delivery network and various security services. These services take place between the user and our hosting provider. In the following, we will try to explain in detail what all this means.
A content delivery network (CDN), as provided by Cloudflare, is nothing more than a network of servers that are connected to each other. Cloudflare has deployed servers around the world, which ensure websites can appear on your screen faster. Simply put, Cloudflare makes copies of our website and places them on its own servers. Thus, when you visit our website, a load distribution system ensures that the main part of our website is delivered by a server that can display our website to you as quickly as possible. The CDN significantly shortens the route of the transmitted data to your browser. Thus, Cloudflare does not only deliver our website’s content from our hosting server, but from servers from all over the world. Cloudflare is particularly helpful for users from abroad, since pages can be delivered from a nearby server. In addition to the fast delivery of websites, Cloudflare also offers various security services, such as DDoS protection, or the web application firewall.

Cloudflare is an active participant in the EU-U.S. Privacy Shield Framework, which regulates the correct and secure transfer of personal data. You can find more information on this at
