Collection of personal data during visits to our website
If you visit our website for information purposes only, i.e. if you transmit no data to us, we only collect the personal data your browser transfers to our server. 

Our website uses the open-source software Matomo to collect anonymous user data for the SITEMA website.

Data of the visitor behavior is collected to detect possible problems like pages not found, problems with the search engine, or unpopular pages. As soon as the data (for example number of visitors which see error pages etc.) is processed, Matomo creates reports for the owners of the website so that they can react (for example by changing the layout, adding new content, etc.).

If you visit our website, we collect the following data; some of the data (marked with (M)) is processed by Matomo:

  • Anonymized IP address (M)
  • Country, region, and town of origin which are determined with limited accuracy from the anonymized IP address (for example to set the display language of the website and to display the contact data of the responsible SITEMA representative) (M)  
  • Date and time of the request (M)
  • Time zone difference to Greenwich Mean Time (GMT)
  • Content of the request (the actual page)
  • Title of the page visited (M)
  • URL of the page visited (M)
  • URL of the previous page (if permitted) (M)
  • Access status/HTTP status code
  • Amount of data transferred
  • Website from which you called our website (referrer URL)
  • Browser type, language, and version
  • Main language of the browser (M)
  • User agent of the browser (M)
  • Operating system
  • Screen resolution (M)
  • Files which users clicked and downloaded (M)
  • External links (M)
  • Duration of page loading (M)
  • Interactions with forms (Matomo: not the content of the forms) (M)
The data will be stored in the log files of our system. The data will not be stored together with any other personal data of the user. We technically need the data to display our website and to ensure its stability and safety. The IP address of the user must be stored as long as the session lasts. The data are stored in log files to ensure the functioning of the website. Additionally the data help us to optimize the website and to ensure the safety of our information technology systems.

The legal basis for storing the data is the General Data Protection Regulation (GDPR), article 6, paragraph 1, letter f. It is our legitimate interest to improve our website, make it stable, functionable and safe.

All data is deleted as soon as it is no longer needed for the original purpose of collection. If data is collected to provide the website, data is deleted as soon as the session ends. If data is stored in log files, data is deleted at the latest after seven days. It is possible that data is stored for a longer time. If this is the case, the IP addresses are deleted or altered so that it is not possible to assign the data to the client the request came from. To provide the website it is required to collect the data. For the operation of the website it is required to store the data in log files. The user therefore has no option to object. If you do not agree to these terms and conditions, we recommend to leave the website.

Google Maps

We use Google Maps on our Contact web page. Google Maps is a web service which visually displays geographic data on interactive maps. By using this service, you get information on our representations all over the world, and you can see amongst others the location of our site in Karlsruhe.
Google transfers the map content directly to your browser which displays the data on the web page. Therefore, we have no influence on the amount of data Google collects for this service. According to our knowledge, the data collected are the IP address, date and time of the visit to the web page, the internet address or URL of the accessed web page, and possibly more.
