General information on the collection of personal data when visiting our online offer

When you visit our website, data is inevitably collected that has to be stored or processed in order to display this website to you. An analysis of your user behavior does not take place.

In principle, all data that is no longer necessary for the fulfillment of our tasks will be deleted at regular intervals.

The basis for data processing is Art. 6 para. 1 lit. f DSGVO. According to this, we may process your personal data if we do so on the basis of a legitimate interest. This legitimate interest lies here specifically in being able to display our website to you.

In the following, we explain which data we collect, process and possibly store for a longer period of time.

When you visit our website, our servers collect so-called server log files. These files are only stored for the duration of your session.
