We will only use and process your personal data within the permissible scope of contract processing or if you have given your informed consent.

We do not pass on your personal data, including your address and e-mail address, to third parties. Excluded from this are our service partners who require the transmission of data for the processing of the contractual relationship or if we have expressly pointed this out. In these cases, however, the amount of data transmitted is always limited to the necessary minimum.

3 Anonymous data collection

You can visit our website without telling us who you are. We only learn the name of your internet service provider, the website from which you are visiting us and the pages of our website you are visiting. This information is only evaluated for statistical purposes. As an individual user, you will remain anonymous and will of course not be merged with your personal data unless you have expressly consented to this or one of the cases listed below applies.

4 Collection of personal data when you visit our website and use our services in general.

As a matter of principle, we only collect personal data if you provide us with it voluntarily and voluntarily. This can be done, for example, when placing an order or for the execution of a contract, a survey or when registering for services which require registration with personal data (e.g. for orders, special offers, competitions, newsletter dispatch or similar). In such cases, we only collect the data to which we are legally entitled and which is absolutely necessary for the fulfilment of the services you have requested (e.g. your name, your address, your telephone number and your e-mail address for ordering processes, for example, only your e-mail address and your first name for personal contact when registering for the newsletter). If we collect personal data from you (e.g. via a contact or order form), you only need to enter the required data. The mandatory data fields are marked accordingly. All additional data provided by you are purely voluntary and do not have to be disclosed by you. If you nevertheless indicate this, then you give us your consent with your disclosure that we may also store and process this data from you for the purpose stated in each case; in some cases we also request your express consent for data protection purposes, which require express consent, which you can of course give voluntarily, is not bound to any further requirements and can be revoked at any time for the future.

For the highest possible security of your data, these are transmitted by SSL coding in coded form. This is to prevent misuse of the data by third parties. Your data will only be stored and processed by us on servers within the European Union. A transfer to third countries does not take place unless we are entitled and/or obliged to do so by law or you have expressly consented in advance. However, these cases are then also clearly identified.

5 Data processing for the performance of the contract

Processing purpose You provide us with your personal data as part of our ordering process, for example. The compulsory data marked in this context are personal data which are necessary for concluding a contract with us. Of course, you are not obliged to provide your personal data. However, we cannot provide the service you require (e.g. contract fulfilment) without your notification of the data required in each case (in the case of an order, e.g. your e-mail address). With some payment procedures we need the necessary payment data in order to pass them on to a payment service provider commissioned by us. The processing of your data entered during the ordering process is therefore always carried out for the purpose of fulfilling the contract.
