If you use this website without transmitting data to us in any other way (e.g. by registration), we only collect technically necessary data which is automatically transmitted to our server by your browser (e.g. browser type/browser version, operating system used, referrer URL, pages called up, length of visit, IP address, date and time of enquiry). This is technically necessary in order to display our website to you. As far as personal data is concerned, Art. 6 (1) lit. f GDPR is the legal basis for the collection. This data will not be combined with other sources of data. We reserve the right to examine this data in retrospect, if we become aware that it has been used for unlawful purposes.

Collection and use of personal data

We only collect and process the personal data (e.g. name, address, email) that you provide to us upon registration, when you order products or services, or when you make enquiries, and only insofar as this is required to substantiate, to establish the content of the legal relationship, or to change the legal relationship. After the contract has been executed, your data will be deleted with regard to the statutory safe-keeping duties, provided that you have not expressly agreed to the further use of this data. We, and persons instructed by us, shall not forward your personal data to third parties without your consent or a relevant official order.

Data transfer during an order and credit assessment

All data which you have made available to us during your order/registration will be stored by us and, insofar as this is necessary for the execution of the contract, we will pass it on to contractual partners within the framework of the order and registration, e.g. to the freight forwarder or the parcel deliverer who usually delivers our shipments to you. Our contract partners may exclusively use the data transmitted in this way to execute the order.

In justified cases (for example direct debit proceedings) we will exchange address and credit assessment information with credit service companies. The service providers can only access the personal information that is required to fulfil the relevant contract.

Data protection information

We comply with the statutory requirements for all data processing activities (collection, processing and transmission). Your data required for the business transaction is stored and transferred to service providers instructed by us as necessary to process the order. Furthermore, address and order information will be collected and processed for our own marketing purposes.
