We use the open-source software "Matomo" for statistical analysis of user access to our web application. The software developers of this tool were in close contact with the Independent Regional Centre for Data Protection Schleswig-Holstein (ULD) when implementing data protection rules and regulations in the source code. This means that Matomo can be used in compliance with German data protection laws.
For statistical analysis only the first byte of your IP address is used (e.g. 192.xxx.xxx.xxx). In addition, this information is made anonymous before being stored. Therefore, any personal reference is excluded.
Data which has been collected and anonymized is not passed to third parties and is analyzed exclusively in-house. It helps us to identify and improve relevant content of GeotIS. If you do not agree to the storage and analysis of data from your visit, then, at any time you may opt out from your data being stored or used as described in the following paragraph.
Objection against statistical analysis
Matomo supports the "Do Not Track" method of current web browsers. If you wish to generally prohibit any analysis of your online behaviour, we recommend that you activate this option in your browser. Alternatively, you can prohibit Matomo web analysis on our web application by unchecking the checkbox in the next section. In this case an opt-out cookie ("piwik_ignore", lifetime one year) will be set.
