Your privacy choice. By default we count page visits anonymously, without cookies and without a profile; "Reject all" stops that as well. With your consent we also recognise your browser on later visits, by a random ID in your browser and a device fingerprint, and keep a visit profile (pages read, time spent, interests, how you found us) on our own server in Frankfurt for our marketing. Authorised staff can view it; it is deleted 13 months after your last visit. External media (YouTube) load only with your consent. Change your choice anytime under "Privacy settings" in the footer; see or delete your profile under "My data". Details: privacy policy, § 7.
✓Necessary. Remember this choice. Proof of your choice (date, text version and, if you consented, your random ID) is kept for 3 years. (always on)
