The recording of data for the provision of the website and the storage of data in log files are essential to operate the website. It is therefore not possible for the user to object.

1.3. Data deletion

The data are deleted as soon as they are no longer required in order to fulfil the purpose of their collection. If data are gathered for the provision of the website, this is the case if the respective visit is ended. In the event that data are stored in log files, this is the case after seven days at the latest. Storage above and beyond this period is possible. In this case, the users' IP addresses are deleted or removed so they can no longer be allocated to the visiting device.

B.  Web analysis

It goes without saying that you have the opportunity to object to your data being collected. The following independent methods are available to you if you wish to object to data collection by the central server:

  1. In your browser, activate the Do-Not-Track setting. As long as this setting is active, our central server will not save any of your data. Important: Do-Not-Track generally only applies to the one device and browser on which the setting is activated. If you use several devices/browsers, you must activate Do-Not-Track separately on each one.
  2. Use our opt-out function. Click on the check mark in the following selection box under in order to stop or reactivate data collection. As long as the selection box is deactivated, our central server will not save any of your data. Important: For the opt-out, we have to store a special recognition cookie in your browser. If you delete this or use a different PC/browser, you have to object to data collection once again on this page.

There is no storage of these data together with other personal data relating to the users.
