We use so-called cookies on our website. These are small text files that are saved by your browser and stored on your terminal device.
The so-called transient (or temporary) cookies are automatically deleted when you close your browser. These include session cookies in particular. These store a certain identifier (the so-called session ID), which makes it possible to recognize your terminal device when you return to our website. This can be used, for example, to save the contents of the virtual shopping basket of an online shop or the login status. Session cookies will be deleted when you log out or close the browser.
The so-called persistent (or permanent) cookies are automatically deleted after a certain period of time; the duration of storage differs depending on the cookie. This can, for example, store user information for reach measurement or marketing purposes or even a login status for a longer period of time.
A distinction must be made between first-party cookies and third-party cookies for both temporary and permanent cookies.  The former are set by the controller, the latter by third-party providers.
You can delete cookies at any time via the security settings in your browser or, for example, also refuse to accept third-party cookies.  If you generally want to object to the use of cookies for online marketing purposes, you can do so through various services or providers, e.g., via the American site www.aboutads.info/choices or the European site www.youronlinechoices.com. Please note that you may then not be able to use all the functions of our website.
On our website, we may use temporary or permanent cookies, as well as first and third-party cookies, e.g. to be able to identify you for subsequent visits if you have an account with us (otherwise you would have to log in again for each visit).  You can find further information about this in our privacy policy where applicable.
We only use cookies that are technically necessary for the operation of our website. The legal basis for the use of cookies is Art. 6(1)(1)(f) GDPR.
