Please read this Privacy Policy, our Terms of Service, and our Data Processing Agreement carefully as you must agree to each in order to have permission to use our service. You will not be able to use our service if you do not agree to these policies.

1.4 What 'Personal Data' means
In this Privacy Policy, we'll be talking a lot about your 'personal data'. If you aren't exactly sure what that means, here is how the term is defined in Article 4 of the European General Data Protection Regulation (GDPR) (and this is how we'll be using the term for the purposes of this Privacy Policy): "Personal data means any information relating to an identified or identifiable natural person ("data subject"). An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person."

1.5 General information on data processing

1.5.1 Extend of processing personal data
We generally only process personal data of our users insofar as this is necessary to provide a functional website and our content and services. The processing of personal data of our users takes place regularly only with the consent of the user. An exception applies in cases in which prior consent cannot be obtained for factual reasons and the processing of the data is permitted by law.

1.5.2 Legal basis for the processing of personal data
Insofar as we obtain the data subject's consent for the processing of personal data, Art. 6 §1 a EU General Data Protection Regulation (GDPR) serves as the legal basis. When processing personal data, that is necessary for the performance of a contract to which the data subject is a party, Art. 6 §1b GDPR as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures. Insofar as processing of personal data is necessary to fulfill a legal obligation to which our company is subject, Art. 6 §1 c GDPR serves as the legal basis. In the event that vital interests of the data subject or another natural person require the processing of personal data, Art. 6 §1 d GDPR serves as the legal basis. If processing is necessary to safeguard the legitimate interests of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not outweigh the former interest, Art. 6 §1 f GDPR serves as the legal basis for processing.

1.5.3 Data deletion and storage duration
The personal data of the data subject will be deleted or blocked as soon as the purpose of storage no longer applies. We may store personal data if this has been prescribed by the European or national legislator in EU regulations, laws or other regulations to which the person responsible is subject. The data will also be blocked or deleted if a storage period prescribed by the standards mentioned expires, unless there is a need for further storage of the data for the conclusion or performance of a contract.

Remarketing is used to show users ads and products that have been identified as being of interest on other sites in the Google Network. For these purposes, a code is executed when Google calls up our website and so-called (re)marketing tags are integrated into the website. These tags are used to store an individual cookie, i.e. a small file, on the user's device (similar technologies can be used instead of cookies). The cookies can be set by various domains, including,,,, or This file records which websites users have visited, what content they are interested in and which offers were clicked on. In addition, technical information on the browser and operating system, referring websites, visiting time and other information on the use of the online offer is stored. The IP address of the user is also recorded, whereby we inform within the framework of Google Analytics that the IP address is shortened within member states of the European Union or in other states which are party to the Agreement on the European Economic Area. All user data is only processed as pseudonymous data. Google therefore does not store names or e-mail addresses. All advertisements shown are therefore not shown specifically for one person, but for the owner of the cookie. This information is collected by Google and transmitted to servers in the USA and stored there. The Google marketing services we use include the online advertising program Google AdWords. In the case of Google AdWords, each AdWords customer receives a different conversion cookie. Cookies can therefore not be tracked through the websites of AdWords customers. The information collected through the cookie is used to compile conversion statistics for AdWords customers who have opted in to conversion tracking. AdWords advertisers learn the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, they do not receive any information that can be used to personally identify users. We may include third-party ads based on Google Marketing Services DoubleClick. DoubleClick uses cookies to enable Google and its partner sites to serve ads based on users' visits to this site or other sites on the Internet.
