3. Security measures

3.1. Pursuant to Art. 32 GDPR and taking into account the state of technology, implementation costs and the type, scope, circumstances and purpose of the data processing and the probability of occurrence and severity of the risk to the rights and freedoms of natural persons, we take suitable technical and organizational measures to ensure a level of protection commensurate with the risk; these measures in particular include the safeguarding of the confidentiality, integrity and availability of data by checking the physical access to the data, as well as their access, input, passing on, protection of availability and their separation. Furthermore, we have established procedures which safeguard the rights of data subjects, the deletion of data and the response to the endangerment of data. In addition, we bear in mind the protection of personal data when we develop or select hardware, software and procedures, in accordance with the principle of data privacy through technology design and through data privacy-friendly default settings (Art. 25 GDPR).

3.2 These security measures in particular include the encrypted transmission of data between your browser and our server.

4. Working with order processors and third parties

4.1 Where in the context of data processing we disclose data to other persons and companies (data processors or third parties), transmit data to them or otherwise grant access to this data, then this is done only on the basis of a legal permission (e.g. if the transmission of the data to third parties, such as to payment service providers, in accordance with Art. 6 para. 1 lit. b GDPR is required for contract fulfilment), if you have given your consent, if there is a legal obligation to do so or on the basis of our legitimate interests (e.g. when deploying agents, web hosting companies, etc.).

5. Transmissions to third countries

When we process data in a third country (i.e. outside the European Union (EU) or the European Economic Area (EEA)) or this is carried out in connection with utilising third-party services or the disclosure or transmission of data to third parties, then this is done only if this serves to fulfil our (pre-)contractual obligations, on the basis of your consent, on the basis of a legal obligation or on the basis of our legitimate interests. Subject to legal or contractual permissions, we process data or have it processed in a third country if the special requirements of Art. 44 ff. GDPR are in place. I.e. the data is processed on the basis of special guarantees for example, such as if a level of data protection is in place that is officially recognised as being equivalent to the level of protection in the EU (e.g. for the US, this is the Privacy Shield) or compliance with officially recognised special contractual obligations (so-called “standard contractual clauses“).
