General Information on Data Processing

Scope of the Processing of Personal Data

As a matter of principle, we only process personal data of our users to the extent that this is necessary for the provision of a functional website as well as our contents and services. The processing of personal data of our users is regularly only carried out with the consent of the user. An exception applies in those cases in which it is not possible to obtain prior consent for actual reasons and the processing of the data is permitted by legal regulations.

Legal Basis for the Processing of Personal Data

Insofar as we obtain the consent of the data subject for processing operations involving personal data, Article 6 1 lit. (a) of the 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 1 lit. (1) (b) DSGVO serves as the legal basis. This also applies to processing operations that are necessary for the performance of pre-contractual measures.
Insofar as the processing of personal data is necessary for the fulfilment of a legal obligation to which our company is subject, Art. 6 1 lit. c DSGVO serves as the legal basis.
In the event that vital interests of the data subject or another natural person make processing of personal data necessary, Art. 6 1 lit. (d) DSGVO serves as the legal basis.
If the processing is necessary to protect a legitimate interest of our company or a third party and the interests, fundamental rights and freedoms of the data subject do not outweigh the first-mentioned interest, Art. 6 1 lit. f DSGVO serves as the legal basis for the processing.

Data Deletion and Storage Period

The personal data of the data subject shall be deleted or blocked as soon as the purpose of the storage no longer applies. Storage may also take place if this has been provided for by the European or national legislator in Union regulations, laws or other provisions to which the person responsible is subject. Data will also be blocked or deleted if a storage period prescribed by the aforementioned standards expires, unless there is a necessity for the continued storage of the data for the conclusion or fulfilment of a contract.

Description and Scope of Data Processing
Each time our website is accessed, our system automatically collects data and information from the computer system of the accessing computer.

  • The user’s operating system
  • The user’s internet service provider
  • The IP address of the user
  • Date and time of access
  • Websites from which the user’s system accesses our website
  • Websites that are accessed by the user’s system via our website
  • Name and URL of the file accessed
  • Message as to whether the retrieval was successful

This data is also stored in the log files of our system. This data is not stored together with other personal data of the user.

Legal Basis for Data Processing

The legal basis for the temporary storage of the data and the log files is Art. 6 para. 1 lit. f DSGVO.

Purpose of the Data Processing

The temporary storage of the IP address by the system is necessary to enable delivery of the website to the user’s computer. For this purpose, the user’s IP address must remain stored for the duration of the session.
The storage in log files is done to ensure the functionality of the website. In addition, we use the data to optimise the website and to ensure the security of our information technology systems. An evaluation of the data for marketing purposes does not take place in this context.
These purposes are also our legitimate interest in data processing according to Art. 6 Para. 1 1 lit. f DSGVO.

Duration of Storage

The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.
In the case of storage of data in log files, this is the case after seven days at the latest. Storage beyond this period is possible. In this case, the IP addresses of the users are deleted or alienated so that an assignment of the calling client is no longer possible.

Possibility of Objection and Removal

The collection of data for the provision of the website and the storage of the data in log files is absolutely necessary for the operation of the website. Consequently, there is no possibility for the user to object.

Online Marketing

Use of Google Ads conversion tracking:

This website uses the online advertising programme “Google Ads” and, within the framework of Google Ads, the conversion tracking of Google Ireland Limited, Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland (“Google”).
We use Google Ads to draw attention to our attractive offers on external websites with the help of advertising media (so-called Google Adwords). We can determine how successful the individual advertising measures are in relation to the data of the advertising campaigns. In this way, we pursue the interest of showing you advertising that is of interest to you, making our website more interesting for you and achieving a fair calculation of advertising costs. The conversion tracking cookie is set when a user clicks on an ad placed by Google. Cookies are small text files that are stored on your computer system. These cookies usually lose their validity after 30 days and are not used for personal identification. If the user visits certain pages of this website and the cookie has not yet expired, Google and we will be able to recognise that the user clicked on the ad and was redirected to this page. Each Google Ads customer receives a different cookie. Cookies cannot therefore be tracked across Google Ads clients’ websites. The information obtained using the conversion cookie is used to create conversion statistics for Google Ads customers who have opted in to conversion tracking. Clients learn the total number of users who clicked on their ad and were redirected to a page tagged with a conversion tracking tag. However, they do not receive any information that can be used to personally identify users. If you do not wish to participate in the tracking, you can block this use by deactivating the Google conversion tracking cookie via your internet browser under user settings. You will then not be included in the conversion tracking statistics. We use Google Ads based on our legitimate interest in targeted advertising pursuant to Art. 6 para. 1 lit. f DSGVO. The use of Google Ads may also involve the transmission of personal data to the servers of Google LLC. in the USA. In the event that personal data is transferred to Google LLC., which is based in the USA, Google LLC. has certified itself for the us-European data protection agreement “Privacy Shield”, which guarantees compliance with the level of data protection applicable in the EU. A current certificate can be viewed here: https://www.privacyshield.gov/list You can obtain further information on Google’s data protection policy at the following Internet address: https://www.google.de/policies/privacy/ You can permanently deactivate cookies for advertising preferences by setting your browser software accordingly or by downloading and installing the browser plug-in available at the following link: https://www.google.com/settings/ads/plugin?hl=de Please note that certain functions of this website may not be available or may only be available to a limited extent if you have deactivated the use of cookies.

Our website uses plugins from the YouTube site operated by Google. The operator of the pages is YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA. When you visit one of our pages equipped with a YouTube plugin, a connection to the YouTube servers is established. This tells the YouTube server which of our pages you have visited.
