    1. We take state-of-the-art organisational, contractual and technical security measures to ensure that the provisions of data protection laws are adhered to and in order to protect the data we process from accidental or intentional manipulation, loss, destruction or access by unauthorised persons.
    2. One of these security measures is the encrypted transfer of data between your browser and our server.
  3. Transfer of data to third parties and third-party providers

    1. All transfer of data to third parties takes place only within the scope of legal requirements. We will transfer user data to third parties only, for example, if it is required for contractual purposes on the basis of Article 6(1)(b) GDPR or based on legitimate interests for the economical and effective conduct of our business operations in accordance with Article 6(1)(f) GDPR.
    2. If we use subcontractors to provide our services, we will take appropriate legal precautions and appropriate technical and organisational measures to protect personal data in accordance with applicable law.

    1. Within our Online Offering, based on our legitimate interests within the meaning of Art. 6(1)(f) GDPR (that is, our interest in the analysis, optimisation and economical operation of our Online Offering), we use content or service offers from third party providers in order to integrate their content and services, such as videos or fonts (collectively referred to hereafter as "Content"). This always presupposes that the third-party providers of this Content perceive the IP address of the users, since they could not send the content to their browsers without the IP address. The IP address is therefore required for the presentation of this Content. We endeavour to use only content whose respective providers use the IP address solely for the delivery of the Content. Third-party providers may also use so-called pixel tags (invisible graphics, also referred to as "web beacons") for statistical or marketing purposes. The "pixel tags" can be used to evaluate information such as visitor traffic on the pages of this website. The pseudonymous information may also be stored in cookies on the user's device and may include, but is not limited to, technical information about the browser and operating system, referring web sites, the time of the visit, and other information regarding the use of our Online Offering.
