Providing access to the website and creation of log files
- Description and scope of data processing
Every time a user accesses a University of Konstanz web page, file or other resource, the following data related to this process is stored in a log file:
- date and time of request
- address and file size ( in bytes ) of the resource requested and/or accessed
- the visitor’s IP address
- request method ( e.g. HTTP GET for requesting a website from the server )
- server response ( HTTP status code, e.g. “file sent”, “file not found”, etc)
- referrer website visited prior to this web site as well as the search terms entered, if available
- Data pertaining to the browser, operating system, and their versions, as available
- connection information from the browser and operating system used, if available
- Legal basis
The legal basis for storing log files is § 6 para 1. lit e) in connection with § 3 GDPR in connection with § 4 Landesdatenschutzgesetz (LDSG, law for the protection of personal data) in the version coming into effect on 6 June 2018.
- Purpose of processing data
The logged information is used to identify, isolate and fix disruptions or errors in the systems needed to operate the University of Konstanz web pages. These may also include disruptions or errors that lead to the restricted availability of information and communication services or allow unauthorised access to the systems.
- Storage duration
The last two bytes of the IP address are deleted after 5 days so that any other data collected in the process can no longer be associated with a particular person.
The anonymised information is used for statistical purposes in order to continually improve the quality of the web services provided.
When a page is visited, the browser will save a so-called “session cookie” to the end device in use. The cookie will be deleted as soon as the browser is closed. The “session cookies” do not contain personal information. It is not intended nor possible to use the session ID to identify a user. The temporary logging of these cookies can be disabled by changing the appropriate settings of the internet browser. This does not affect the access or use of the page, but disabling cookies may increase the server’s response time slightly.
This website is using Matomo, an Open Source, self-hosted software for collecting anonymous usage statistics for this website.
The data is used to analyse the behaviour of the website visitors to identify potential pitfalls like not found pages, search engine indexing issues and to find out which contents are the most appreciated. Once the data (number of visitors reaching a not found pages, viewing only one page…) is processed, Matomo is generating reports for website owners to take action, for example changing the layout of the pages, publishing some fresh content… etc.
Matomo is processing the following data:
Anonymized IP-address by removing the last 2 bytes (so 18.104.22.168 instead of 198.51.100.54)
Pseudo-anonymized Location of the user (generated from the anonymized IP-address)
