 This website incorporates videos from the YouTube website. The website is operated by Google Ireland Limited ("Google"), Gordon House, Barrow Street, Dublin 4, Ireland.

When you visit one of our websites that embeds YouTube, a connection is made to YouTube's servers. This tells the YouTube server which of our pages you have visited.

YouTube may also store various cookies on your device. These cookies allow YouTube to obtain information about visitors to this website. This information is used, among other things, to gather video statistics, improve the user experience and prevent fraud. The cookies remain on your device until you delete them.

If you are logged in to your YouTube account, you allow YouTube to associate your browsing behavior directly with your personal profile. You can prevent this by logging out of your YouTube account.

YouTube is used in the interest of an attractive presentation of our online offers. This represents a legitimate interest in the sense of Art. 6 para. 1 lit. f GDPR. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR; the consent can be revoked at any time.

Legal Basis for the Processing of Personal Data

In the following, we inform you about the legal basis of the processing of personal data: 

Disclosure of Personal Data to Third Parties and Processors

Without your consent, we will not pass on any data to third parties. Should this be the case, however, the transfer will take place on the basis of the aforementioned legal bases, e.g., when data is passed on to online payment providers for the purpose of fulfilling a contract or due to a court order or due to a legal obligation to surrender the data for the purpose of criminal prosecution, to avert danger or to enforce intellectual property rights.

We also use contract processors (external service providers e.g. for web hosting of our websites and databases) to process your data. If data is passed on to the processors within the framework of an agreement for order processing, this is always done in accordance with Art. 28 GDPR. We select our processors carefully, check them regularly and have been granted the right to issue instructions regarding the data. In addition, the processors must have taken suitable technical and organizational measures and comply with the data protection regulations according to BDSG n.F. and GDPR.

Data Transfer to Third Countries

With the adoption of the European General Data Protection Regulation, a uniform basis for data protection in Europe was created. Your data is therefore processed primarily by companies to which the GDPR applies. If, however, processing is carried out by services of third parties outside the European Union or the European Economic Area, they must comply with the special requirements of Art. 44 ff. GDPR. This means that the processing is carried out on the basis of special guarantees, such as the EU Commission's officially recognized determination of a level of data protection corresponding to that of the EU or compliance with officially recognized special contractual obligations, the so-called "standard contractual clauses". In the case of US companies, submission to the so-called "privacy shield", the data protection agreement between the EU and the USA, fulfils these requirements.

Deletion of Data and Duration of Storage

Unless expressly stated in this data protection declaration, your personal data will be deleted or blocked as soon as the purpose for which it was stored no longer applies, unless further storage is necessary for evidence purposes or if there are legal storage obligations to the contrary. This includes, for example, commercial storage obligations for business letters according to § 257 para. 1 HGB (6 years) and tax storage obligations according to § 147 para. 1 AO of receipts (10 years). When the prescribed retention period expires, your data will be blocked or deleted, unless the storage is still necessary for the conclusion or fulfillment of a contract.
