If you do not agree with the storage and evaluation of the data in connection with your visit and the use of our websites, then the storage and use can be contradicted subsequently at any time by clicking on the mouse. In this case, a so-called opt-out cookie is stored in your browser, which means that Piwik does not collect any session data. We expressly point out that if you delete your cookies, the opt-out cookie will also be deleted and may need to be reactivated by you.
