Objective and basic information on the legal basis of data processing
This privacy policy clarifies the nature, scope, and purpose of the processing of personal data within our online web presence and the associated websites, functions, and content. The privacy policy applies regardless of the domains, systems, platforms, and devices used (e.g., desktop or mobile) used to access the online presence.
We process the personal data of our users only in compliance with the relevant data protection regulations in accordance with the principles of data minimization. As a rule, processing of personal data occurs only with user consent. An exception applies where the processing of data is permitted by law.
We take state-of-the-art organizational, contractual, and technical security measures to ensure compliance with the provisions of data protection laws and to protect the data processed by us against accidental or intentional manipulation, loss, destruction, or access by unauthorized persons.
If content, tools, or other means from third-party providers registered abroad (e.g., YouTube videos) are used as part of our online presence, it can be assumed that data will be transferred to the countries in which the third-party providers are based.
If you have consented to data processing, we process your personal data on the basis of Article 6 paragraph 1 letter a GDPR or Article 9 paragraph 2 letter a GDPR, insofar as special categories of data are processed in accordance with Article 9 paragraph 1 GDPR. In the event of express consent to the transfer of personal data to third countries, data processing is also carried out on the basis of Article 49 paragraph 1 letter a GDPR. If you have consented to the storage of cookies or access to information in your end device, data processing is also carried out on the basis of Section 25(1) of the German law on data protection and privacy protection in telecommunications (Telekommunikation-Digitale-Dienste-Datenschutz-Gesetz, TDDDG). Consent can be revoked at any time. If your data is required to fulfill a contract or to carry out precontractual measures, we process your data on the basis of Article 6 paragraph 1 letter b GDPR. Furthermore, we process your data if this is necessary to fulfill a legal obligation on the basis of Article 6 paragraph 1 letter c GDPR. Data processing may also be carried out on the basis of our legitimate interest in accordance with Article 6 paragraph 1 letter f GDPR. Information on the relevant legal bases for each individual case is provided in the following paragraphs of this privacy policy.
Recipients of personal data
We work with various external bodies as part of our operations. In some cases, it is also necessary to transfer personal data to these external bodies. We only transfer personal data to external bodies if this is necessary in the context of fulfilling a contract, if we are legally obliged to do so (e.g. passing on data to tax authorities), if we have a legitimate interest in passing on the data in accordance with Article 6 paragraph 1 letter f GDPR, or when permitted on another legal basis.
When using external processors, we only pass on our customers’ personal data on the basis of a valid contract for order processing. Joint processing is only conducted under a joint processing agreement.
Storage period
Unless a more specific storage period has been specified in this privacy policy, your personal data will be stored until the purpose for data processing no longer applies. If you exercise your right to request deletion of your data or revoke your consent to data processing, your data will be deleted unless we are legally required to retain it (e.g., retention periods under tax or commercial law); in the latter case, deletion will take place after these reasons no longer apply.
