Web analysis through Matomo (formerly PIWIK)

Scope of the processing of personal data
We use the open source software tool Matomo (formerly PIWIK) on our website to analyse the surfing behaviour of our users. The software sets a cookie on the user's computer (for cookies, see above). If individual pages of our website are called up, the following data is stored:

Two bytes of the IP address of the user's calling system
The website called up
The website from which the user accessed the website called up (referrer)
The subpages called up from the website called up
The time spent on the website
The frequency with which the website is called up
The software runs exclusively on the servers of the Ruhr University Bochum. Personal user data is only stored there. The data is not passed on to third parties.

The software is set in such a way that the IP addresses are not stored completely, but 2 bytes of the IP address are masked (e.g.: In this way, it is no longer possible to assign the shortened IP address to the calling computer.

2 Purpose of data processing and legal basis
The processing of users' personal data enables us to analyse the surfing behaviour of our users. By evaluating the data obtained, we are able to compile information on the use of the individual components of our website. This helps us to continuously improve our website and its user-friendliness. By anonymising the IP address, the interest of users in the protection of their personal data is adequately taken into account.

The legal basis for the processing of the users' personal data is Art. 6 para. 1 lit. e DSGVO.

3. duration of storage
The data is deleted as soon as it is no longer required for our recording purposes. In our case, this is the case after 90 days.
