Privacy Notice

Protecting your personal data is something we take very seriously; we are committed to strictly adhering to the rules of data protection. The following statement gives you an overview of how we ensure this protection, as well as what type of data is collected and processed for what purpose in connection with this competition.

Collecting, Processing, and Using Personal Data

To conduct the raffle as part of the “BISON APP ADVENT CALENDAR” sweepstakes, we use the names and email addresses stored when registering with BISON online services. We need these in order to carry out the raffle, allocate the prize, and arrange payments by blocknox. The legal basis for this is provided by article 6, paragraph 1b) of the GDPR. Aside from the transmission of each winner’s data to blocknox for the purpose of delivering their prize, no data will be passed on to third parties. After completing the raffle and distributing the prizes, all collected data will be deleted except for the winner data. The winners’ personal data will be kept on file because we are subject to special legal obligations regarding the retention of business records in the context of raffles. The legal basis for this is article 6, paragraph 1c) of the GDPR.

Revocations, Amendments, Corrections, and Updates

You always have the right to receive information about your stored personal data, its recipients, and the purpose of data processing. Information about stored data (article 15 of the GDPR) is provided by the data protection officer of EUWAX AG. In addition, you have the right to correct any inaccurate data (article 16 of the GDPR) and – insofar as this does not conflict with any legal obligation to retain data – to block and delete your personal data, and object to its processing (articles 17, 18, and 21 of the GDPR).

You can, at any time, revoke your consent to the processing of your personal data with future effect. A declaration of revocation does not render the processing of personal data carried out on the basis of previously declared consent unlawful. The revocation is not bound to any form. You can send your revocation to our data protection officer by email to or by post to EUWAX AG, Börsenstraße 4, 70174 Stuttgart.
