You may freely revoke any consent you have given for data processing at any time. However, this does not affect the lawfulness of the processing carried out on the basis of your consent prior to revocation. If you revoke your consent or effectively object to further processing based on your consent, we will no longer process the data for these purposes. The exercise of your rights may be limited in individual cases due to legal restrictions, particularly where processing is necessary (see Article 17(3) of the GDPR), where retention obligations exist, or where the effort involved would be disproportionately high (see Section 34(1) and (4), Section 35 of the BDSG) or in the event of an overriding public interest (see Section 36 of the BDSG). If you have any questions regarding your rights or any restrictions on them, please contact our Data Protection Officer using the contact information provided in Section 2.
