Privacy Policy

Our website addresses are:

What personal data we collect and why we collect it

The owners don’t like tracking tools, but sometimes they look after how many visitors requested the website, what kind of articles are more requested than others, from where the users accessed our website. Single users are not interesting for us. This interest do we interprete as the in the European Privacy Regulation mentioned “legitimate interest” – concrete Art. 6 – EU-GDPR – Lawfulness of Processing.

We are using the web-fonts of Google Fonts. By every request of our website the Google Fonts page is automatically requested and Google Fonts collects  IP-Adressen of their users. This seems not to be connected with other Google services.

Our hosting service provider Strato AG is offering logfiles  (which are standard in webhosting services). Logfile data are automatically saved any time when somebody is accessing a page. They collect when a user is accessing a html or image file. Based on these data the owner of the website might receive statistic information. Our logfiles follow the standard, the Apache Combined Log Format, including the following information:

  • Anonymized client IP:  For finding out, from where users access our service we collect IP adresses. Strato AG saves them maximum 7 days, after this period they becoime anonymized. From data protection reasons, the owner is from the begin on only authorized to see them in an anomyzed form.
  • Timestamp: At what day to what time a visitor opened a website.
  • Request-line: The path to the goal-address without the domain. If a user is clicking on a picture behind this behind this is in example the URL ““.
  • Status Code: Maybe you have seen a 404 page. This is always shown if a requested page or file cannot be found on the server. 404 is the status code. The  Internet Assigned Numbers Authority has defined some more status codes relevant for failure analysis: In example 200 means “OK” – a user was able to receive the requested page or file.
  • Size of the response body: If a user is requesting our website they are downloading temporary data, in example pictures or texts in their browser. The logfile shows how big these data are.
  • Referer sent from the client: Shows from where a visitor accessed our service.
  • User Agent sent by the client: The user’s type and version of the browser and operating system.
  • Remote User: Usually empty. Strato AG is saving data only then, if somebody is logging into our website on the basis of http-basicauth. This is a not state-of-the-art procedure for user authentification. In the meantime most websites use javascript  approachs not logging remote users.

Some of the in the following mentioned aspects might be not relevant to you as we don’t use tracking or other analytical tools.  But you never know if not thanks to polugins or content from other parties strange things happen. We herewth explain that we try to use only such plugins conform with data security standards
