“Cookies” are small files that are stored on users’ computers. Various pieces of information can be saved within the cookies. A cookie serves primarily to store the information on a user (or the device on which the cookie is stored) during or even after his visit to an online offering. Cookies that are deleted after a user leaves an online offering and closes his browser are called temporary cookies, or “session cookies” or “transient cookies.” The contents of a shopping cart in an online shop or a login status can be stored in such a cookie, for example. Cookies that remain stored after the browser is closed are referred to as “permanent” or “persistent.” For example, the login status can be saved if the users visit them after several days. Likewise, the interests of the users, which are used for range measurement or marketing purposes, can be stored in such a cookie. “Third Party Cookies” are cookies that are offered by providers other than the person responsible that operates the online offering (otherwise, if they are only their cookies, they are referred to as “First-Party Cookies”).

We may use temporary and permanent cookies and explain them in our data protection declaration.

If the users do not want cookies to be stored on their computers, they are asked to deactivate the corresponding option in the system settings of their browser. Stored cookies can be deleted in the system settings of the browser. The exclusion of cookies can lead to functional limitations of this online offering.

We use external payment providers, through whose platforms we and the users can carry out payment transactions. We use these external payment providers to offer our users an effective and safe payment option.

The data processed by the payment service provider include inventory data, such as the name and address, bank details, e.g. account numbers or credit card numbers, passwords, TANs and checksums as well as the contract totals and recipient-related information. The information is required in order to perform the transactions. However, the data entered will only be processed by and stored at the payment service provider. That means we do not receive any account or credit card-related information, but only information with confirmation or negative assessment of the payment. Under certain circumstances, the data is transmitted by the payment service provider to the credit agencies. This transmission is intended for the identity and credit check. To do this, we refer to the General Terms and Conditions and Data Protection Information of the payment service providers.

The payment transactions are subject to the General Terms and Conditions and Data Protection Information of the respective payment service providers, which may be accessed on the respective websites or transaction applications. We refer to this also for the purpose of further information and assertion of rights of revocation, information and rights of other persons concerned.
