What cookies do we use and why
We use session cookies
For a functioning and individualized browsing experience, we use so called "session cookies" which will help to identify you while using our website. These "session cookies" will be deleted automatically and immediately after you close your browser.
We use functional cookies
We also use a "cookie notifier" cookie, which saves your decision either to agree with the usage of cookies on our website or not. It is saved automatically upon your click on one of the two options available. Your acceptance of our cookies is stored for one year from the acceptance date. If you decide to refuse our cookies, your decision will be stored for 30 days. During this time the cookie information banner will not be shown again.
We use analytical cookies
Our website uses Matomo, formerly Piwik, an open source web analytics tool. With this tool we track how often visitors use a page of our website, which pages visitors go to most often, and if they get error messages from our pages. Your IP address will be processed in a pseudonymized manner by deleting the last three figures. That way we are no longer able to directly identify you as an individual. The software from Matomo is running on servers of our in-house service provider in Germany and the information generated by the cookie about your use of the website (including your pseudonymized IP address) will be stored on the server of our in-house service provider in Germany. The IP-address that is transmitted will not be merged with any other data collected by us. We will delete this data within three years. If you decide to set a “do-not-track” preference in your web browser or on your mobile device, your visit will not be tracked.
We use social media cookies and plugins
If you activate plug-ins or activity feeds of social media providers (such as Facebook, Twitter, YouTube, LinkedIn, Instagram, and WhatsApp), your web browser will connect to the servers of the respective providers and send your specific user data. These plug-ins and activity feeds are deactivated by default. As soon as you activate such plug-ins or activity feeds, you provide your consent to transmit your data.
In addition, if you are currently logged in to a social network of one of the above mentioned providers; your activity may be linked to your user account at the same time.
