The website operator has a legitimate interest in the storage of cookies for the technical, error-free and optimized delivery of the related services. Insofar as other cookies are stored (e.g. cookies for the analysis of your surfing behavior), they are treated separately in this data-protection declaration.

These can be in particular: Hotels, travel agencies, the Federal Foreign Office, other authorities of foreign countries for issuing visas. Depending on your place of residence and the event location, these recipients may also be located in third countries outside the EU or the EEA for which no adequacy resolution of the EU Commission exists.

Vimeo also obtains your IP address. This also applies even if you do not have a Vimeo account or are not logged in. The information collected from Vimeo is transmitted to the Vimeo server in the US.
    If you are logged into your Vimeo account, you allow Vimeo to assign your surfing habits directly to your personal profile. You can prevent this by logging out of your Vimeo account.
    For further information on the handling of user data, please refer to Vimeo's privacy policy at:
