Our web server is operated by Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany, e-mail:

2. Collected Data

Our server automatically record information created by your use of the web site. This may include data such as:

  • your pseudonymised IP address
  • browser type
  • operating system
  • referring web apge
  • pages visited
  • location
  • carrier
  • search terms
  • date and time

3. Pseudonymised IP

Only pseudonymised IP addresses of visitors to the website are stored. At the web server level, this happens by default by storing an IP address 123.123.123.XXX in the log file instead of the visitor’s actual IP address, for example, The “XXX” is a random value between 1 and 254, so it is no longer possible to establish the true identity of the visitor.

4. Data Usage

The data are used to measure, customize, and improve our services. We may aggregate this data in order to create statistical information regarding our services and its use, which we may then share with third parties or make publicly available. However, none of this information would include anything that could be used to identify you individually.

5. Third-Party Providers

We currently do not integrate any other online services into this website. Therefore, no third-party service provider can perform tracking.

6. Cookies
