III. Information about the data processing

Your data processed when using our website will be deleted or blocked as soon as the purpose of the storage ceases to apply, the deletion of the data does not conflict with statutory record retention obligations and subsequently no other information is provided on individual processing methods.

Server data

Data is transmitted by your Internet browser to us or to our web space provider for technical reasons, in particular to ensure a secure and stable website. These so-called server log files collect the type and version of your Internet browser, the operating system, the website from which you have navigated to our website (referrer URL), the webpage (s) of our website you are visiting, the date and time of access as well as the IP address of the Internet connection from which our website is used.

The data collected in this way will be stored temporarily, but not together with other data from you.

The data shall be processed on the basis of Article 6(1)(f) of the GDPR. Our legitimate interest is the improvement, stability, functionality and security of our website.

The data will be deleted as soon as it is no longer necessary to retain it for the purpose it was collected. If the data is collected to provide access to the website, this is the case when the respective session ends. Otherwise, all or part of the data will be excluded from deletion until final clarification of an incident.

Session Cookies

Only temporary session cookies are created. These cookies process certain information about you, such as your browser or location data, or your IP address.

This processing makes our website more user-friendly, effective and secure, as the processing allows us to reproduce our website in different languages or to offer a shopping cart function, for example.

The legal basis for this processing is Article 6(1)(b) of the GDPR, provided that these cookies are used to process data required to initiate the contract or to execute the contract.

If the processing does not serve the purpose of initiating the contract or the execution of the contract, our legitimate interest is to improve the functionality of our website. The legal basis is then Article 6(1)(f) GDPR. These session cookies are deleted when you close your internet browser.

Removal option

You can prevent or restrict the installation of cookies by setting your Internet browser. You can also delete previously saved cookies at any time. However, the steps and measures required to do this will depend on your specific Internet browser. If you have any questions, please use the help function or documentation of your Internet browser or contact its manufacturer or support. In the case of so-called Flash cookies, however, processing cannot be prevented via the settings of the browser. Instead, you need to change the setting of your Flash player. The steps and measures required for this also depend on your specific Flash player. If you have any questions, please also use the help function or documentation of your Flash player or contact the manufacturer or user support.

However, if you prevent or restrict the installation of cookies, this may result in not all functions of our website being fully usable.

Execution of contract

We shall use the data transmitted by you for the use of our range of goods and/or services for the purpose of executing the contract and for this reason the data is required.

Conclusion and execution of contract is not possible without the provision of your data.

The legal basis for the processing is Article 6(1)(b) GDPR.

If a contractual relationship is established, we are subject to the statutory retention periods as defined in the German Commercial Code and we shall delete your data at the end of these periods.

As part of the execution of the contract, we shall provide your data to the transport company commissioned with the delivery of goods or to the financial service provider, insofar as the provision of the data is required for the delivery of goods or for payment purposes.

The legal basis for the provision of the data is then Article 6(1)(b)GDPR.


Contact requests / contact options

The provision of your personal data is voluntary. However, we can only process your request if you provide us with your name, your email address and the reason for the request.

Nature and purpose of processing

The data you enter is stored for the purpose of individual communication with you. This requires that you provide us with a valid email address and your name. This is used to assign the request and reply to it subsequently. The provision of further data is optional and voluntary.

Legal basis

The data entered on the contact form are processed on the basis of a legitimate interest (Art. 6(1)(f) GDPR).

We provide the contact form for you to easily contact us. Your information will be stored for the purpose of processing the request and for possible follow-up questions.

If you contact us to enquire about an offer, the data entered on the contact form will be processed to implement pre-contractual measures (Art. 6(1)(b) GDPR).

The legal basis for this processing is Article 6(1)(f) GDPR.

Your data will be deleted if your enquiry has been finally answered and deletion is not in breach of any statutory record retention obligations, such as in the event of subsequent execution of contract.


To protect the security of your data during interactive transmission, we use corresponding state-of-the-art "https" encryption methods.

Nature and purpose of processing
