General information about the processing of personal data, recipients, transfers, legal bases and your data subject rights can be found in our Privacy Policy.

4. Managing cookies
You make your initial choice through the cookie banner. Later, you can change your selection on the website through “Cookie settings” in the footer and in the application through your account privacy settings. There you can withdraw consent as easily as you gave it.
You can also use your browser settings to view and delete cookies and entries in local storage or session storage. If you delete or block strictly necessary entries, login, language settings or display features may not work as intended.
