Information about individual processings

Processing of log data (access data): When using the web service, the access to the pages, whether or not the access was successful, the time, the data volume transferred and the IP address of the device are evaluated in order to recognise errors. The processing happens only internally and on the basis of Art. 6(1)(f) EU-GDPR, whereas the interest lies in error detection. The stored log data is deleted automatically after 7 calendar days.

Automatic log-in on smartphones

When using the web service with an account, it is possible to stay logged in with a smartphone. For this, a cookie is placed on the device with the encrypted log-in data. Simultaneously, a digital fingerprint of the device is placed on the server. The digital fingerprint is calculated on the basis of various parameters. For this, following information is evaluated:

  • SCREEN_SIZE_AND_COLOR_DEPTH (screen size and color depth)
  • DEVICE_ATTRIBUTES: id, model, vendor, build, device_os_version (attributes of device in use: ID, model name, manufacturer, series, OS version of device)
  • ACCEPT_LANGUAGE (language settings)
  • TIME_ZONE (time zone)
  • DEVICE_TYPE (device type)
  • BROWSER_TYPE (browser type)

The data used for the identification of the device is stored on the university server. The storage and processing occurs based on an agreement in accordance with Art 6(1)(a) EU-GDPR, which is provided by the user of the device when activating the automatic log-in function. No data is shared with third parties. The data is used exclusively for the clear identification of the device used, in connection with the automatic log-in. An automatic log-in is only successful when the digital fingerprint matches, the username and password can be decrypted and the actual log-in data matches. Automatic log-in will be deleted automatically should it not be used for 4 weeks. Additionally, the user can always deactivate automatic log-in in their account settings, e.g. when the device is lost. By storing the device´s data mentioned above, the user can keep multiple devices seperate in his/her account and deactivate automatic log-in for individual devices. The processing of the data is legitimized by the agreement up to the point of withdrawal.

Use of Matomo

We use Matomo on our website to analyze the usage behavior of our visitors. Matomo collects data on things like the referrer website a particular user accessed before visiting our website, the subpages of the website the user visits, the amount of time the user spends on a web page, or how often the user visits the page.

The IP address you use to access our website is anonymized. Matomo is configured to mask two bytes of the IP address (e.g.: This makes it impossible to associate the IP address with the device used to access the site.

Matomo sends text files (so-called cookies) to your web browser. For the analysis of web page behavior, the usage information stored on the cookie is sent to our computers. These data are stored exclusively on University of Freiburg servers. The stored usage data are not passed on to third parties. They are not combined with data collected from other pages requiring a disclosure of personal data.

The analysis of the usage behavior of our visitors helps us to optimize our website and make it more user-friendly. This constitutes our legitimate interest in processing data in accordance with § 6 para. 1 lit. f GDPR.
By anonymizing the IP address, we take into sufficient account the interest of the users in protecting their personal data.

You can prevent cookies from being stored on your computer via a corresponding browser setting; however, we would like to point out that if you do so you will not be able to use some functions of our website to their full extent (see above).
