Privacy policy

Data protection is a high priority and this Privacy Policy informs you, as a visitor to this website, about the nature, scope and purpose of the personal data that may be collected, used and processed, and your rights. The terms used in the following, such as “personal data” or “data controller”, correspond to those used by the European Directive and Regulation Authorities pursuant to the adoption of the Basic Data Protection Regulation (GDPR).


All data processing is carried out in accordance with the requirements of the European Data Protection Basic Regulation (DS-GVO/GDPR) and the rules set out below. Art. 6 I GDPR serves as the legal basis for all processing operations for which we obtain consent for a specific processing purpose. The criterion for the duration of the storage of personal data is the respective legal retention period or the objection or termination. After expiry of the period, the corresponding data is routinely deleted if it is no longer required for the fulfilment of the contract or purpose or for the initiation of a contract.

The use of the website is generally possible without any indication of personal data.

For selected services of this website, however, it may be necessary to process personal data. In such a case, and if there is no legal basis for such processing, we generally obtain your consent.

The processing of personal data, such as the name, address, e-mail address or telephone number of a person concerned, is always carried out in accordance with the basic data protection regulation and in compliance with the rules disclosed below. This means that the user is fully entitled to the legally indispensable rights, such as

a) Right to confirmation
b) Right to information
c) Right of rectification
d) Right of cancellation (right to be forgotten)
e) Right to limit processing
f) Right to data transferability
g) Right of appeal
h) Automated decisions in individual cases including profiling
i) Right to revoke a data protection consent

To assert these rights it is sufficient to contact the person responsible for data processing (see below).

The Data Processor processes and stores personal data of the data subject only for the period of time necessary to achieve the purpose of storage or if this is provided for by the European Directive and Regulation Giver or another legislator in laws or regulations to which the Data Processor is subject. If the storage purpose or the permitted or prescribed storage period ceases to apply, the personal data will be blocked or deleted routinely and in accordance with the law.

Technical and organizational measures have been taken to ensure that the personal data processed via this website is protected as completely as possible. Nevertheless, Internet-based data transmissions can generally have security gaps, so that absolute protection cannot be guaranteed. For this reason, it is generally possible to transmit personal data by alternative means, for example by telephone.

Contact details

This website contains all necessary information for a quick contact by telephone or by electronic means, the latter including a general contact e-mail address. If contact is made by e-mail or via a contact form, the personal data transmitted will be stored automatically. Such personal data transmitted to the person responsible for data processing on a voluntary basis is stored for the purpose of processing or contacting. This personal data will not be passed on to third parties.


Cookies are a standard technology for websites and servers. They are text files that are placed and stored on a computer system via an Internet browser to record details about the course of the visit. Cookies may also contain personal information, such as a unique cookie ID, the time of access, the location (IP address) from which access was made and the frequency of visits to this website. With each website visit, this potentially personal information is also transferred to the cookie user, such as Google in the United States of America or a social media platform.

This website potentially uses cookies directly or indirectly via integrated functions to provide user-friendly services. Visitors can prevent the use of cookies at any time by means of a corresponding setting in the Internet browser they use and thus permanently object to the setting of cookies. Furthermore, cookies that have already been set can be deleted at any time via the Internet browser or specific help programs. If the website visitor deactivates the setting of cookies in the Internet browser used, not all functions of this website may be fully usable.

Collection of general data and information (“server logs”)

This website records a number of general data and information with each visit or page view, which are stored in log files of the server; these include, among other things, a) browser type and version used, b) operating system used, c) website from which an accessing system has reached this website, the so-called “referrer”, d) accessed sub-pages, e) date and time, f) IP address of the accessing system (or Internet service provider), and g) supplementary primarily technical data and information which serve to avert danger in the event of attacks on this website or the connected servers.

This data is not used to draw conclusions about visitors, but is used for service quality and correctness, including advertising, as well as operational stability and security. These anonymously collected data and information are therefore evaluated statistically on the one hand and also with the aim of increasing data protection and data security, in order to ultimately ensure an optimum level of protection for the personal data processed by us.

The anonymized data of the server log files are stored separately from all personal data provided by a person concerned and are only made available to law enforcement authorities to the extent necessary in the event of a cyber attack for the purpose of criminal prosecution.

General rules for possible registrations

Visitors to this website have the voluntary option of registering by providing personal data, including for a newsletter. The personal data that is transmitted to the data processor in this process is determined by the respective input mask used for registration. All personal data entered is collected and stored solely for internal use by the data processor and only for his own purposes. The Data Processor may arrange for the transfer to one or more processors, such as a marketing service provider, who will also use the personal data solely for internal use attributable to the Data Processor.

Within the scope of such a registration, which is always voluntary, the visitor’s IP address, date and time of registration and registration-specific data, such as an e-mail address, are stored. The storage of this data is done with the aim of providing the desired service and preventing misuse of the services. In this respect, the storage of this data is necessary to secure the website by the person responsible for data processing. As a matter of principle, this data will not be passed on to third parties unless there is a legal obligation to do so or the passing on of such data serves the purpose of criminal prosecution.

Registered persons are free to change the personal data provided during registration at any time or to have it completely deleted from the data stock of the person responsible for data processing.

The data processing officer will provide any person concerned with information on what personal data about the person concerned has been stored at any time on request. In addition, the data controller shall correct or delete personal data at the request or notification of the data subject, provided that this does not conflict with any statutory storage obligations.

Declarations of consent that may have been made via double opt-in procedures can also be revoked at any time. After a revocation, these personal data will be deleted by the data processing officer. Cancellation of services, e.g. from receiving a newsletter, is automatically interpreted as a revocation.

Subscription of a newsletter

Interested parties, such as existing or potential customers and business partners, are informed about current activities and offers by means of a newsletter at regular intervals. Users are given the opportunity on the website to subscribe to such a newsletter on selected topics or activities. The personal data collected when ordering the newsletter and transmitted to the data processing officer is derived from the input mask used for this purpose. A valid e-mail address and a corresponding registration are indispensable. In addition to the general procedures and rules for registration, a confirmation e-mail will be sent to this e-mail address in the case of the newsletter for legal reasons using the double opt-in procedure. This confirmation mail serves the examination whether the owner of the E-Mail address authorizes the receipt of the newsletter as a person concerned. The dispatch of the newsletter can be contradicted at any time and can be terminated.

For newsletter tracking purposes, e-mails sent may contain so-called tracking pixels; these are miniature graphics that can be stored and evaluated by the data controller in order to optimize newsletter dispatch and to adapt the content of future newsletters, e.g. even better to the interests of the data subject. This personal data is not passed on to third parties.

Use and integration of Facebook

The data processor has potentially integrated components of the company Facebook on this website. Facebook is a social network and serves to exchange opinions and experiences, or enables the community to provide personal or company information. If the visitor is logged in to Facebook at the same time, Facebook recognizes with each visit to this website which specific page of the website has been visited and which button has been clicked, such as the “Like” button; the same applies to comments made. This information is collected by the Facebook component and assigned by Facebook to the respective Facebook account of the visitor. This means that Facebook assigns this information to the personal Facebook account of the person concerned and stores this personal data.

If the visitor to this website does not want this information to be transmitted to Facebook in this way, the transmission can be prevented by logging out of the Facebook account before accessing this website.

The operating company of Facebook is Facebook, Inc. 1 Hacker Way, Menlo Park, CA 94025, USA. The person responsible for processing personal data, if a data subject lives outside the USA or Canada, is Facebook Ireland Ltd, 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland. The data policy published by Facebook, which is available at, provides information about the collection, processing and use of personal data by Facebook. It also explains which setting options Facebook offers to protect the privacy of the person concerned. In addition, various utilities are available that make it possible to suppress data transmission to Facebook. Such utilities can be used by the data subject to suppress data transfer to Facebook.

Use of Google Analytics

The person responsible for data processing has potentially integrated the Google Analytics component (with anonymization activated) on this website. Google Analytics is a website analysis service and is used to analyze the flow of visitors to websites for the purpose of optimization and cost-benefit analysis. Google uses the data and information obtained to evaluate the use of the website and its sub-pages and to create reports on this.

Within the framework of the website analysis, data on the behaviour of the website visitors is collected, collected and evaluated, including which sub-pages of this website were accessed or how often and for how long a subpage was viewed. By means of the anonymization function activated by the data processor in Google Analytics, the IP address is anonymized by truncation if the access to this website is from a member state of the European Union or from another state party to the Agreement on the European Economic Area.

Google Analytics uses cookies for its functionality; this gives website visitors the cookie control options described above, in particular for deactivating Google Analytics records. Furthermore, there is the further possibility to object to the collection of data generated by Google Analytics and related to the use of this website, as well as the processing of this data, by Google and to prevent such collection by downloading and installing a browser add-on under the link This browser add-on informs Google Analytics via JavaScript that no data and information about visits to the respective website may be transmitted to Google Analytics. Google considers the installation of the browser add-on to be an objection in itself. In principle, the correct installation of this add-on is the responsibility of the website visitor.

The operating company of the Google Analytics component is Google Inc, 1600 Amphitheatre Pkwy, Mountain View, CA 94043-1351, USA. Further information and Google’s applicable privacy policy can be found at and Google Analytics is explained in more detail at this link

Use and application of Instagram

The person responsible for data processing has potentially integrated components of the Instagram service on this website. Instagram is an audio-visual platform that allows users to share photos and videos, as well as to disseminate such data on other social networks.

If the website visitor is logged into Instagram at the same time, Instagram recognizes every page and subpage view of this website, whether the visitor clicks on the Instagram component or not. This information is collected by the Instagram component and is associated by Instagram with the relevant Instagram account of the person concerned. If the visitor clicks on one of the Instagram buttons integrated in the website, the data and information transmitted with the button is assigned to the Instagram account of the logged-in person concerned and stored and processed by Instagram.

If the visitor to this website does not wish to receive such information from Instagram, the transmission can be prevented by logging out of the Instagram account before accessing this website.

Instagram LLC, 1 Hacker Way, Building 14 First Floor, Menlo Park, CA, USA, is the operating company of the Instagram services. Further information and Instagram’s applicable privacy policy can be found at and

Twitter deployment and use

The data processor has potentially integrated components of Twitter on this website. Twitter is a multilingual publicly accessible microblogging platform where users can post and distribute short messages (so-called tweets). These short messages can be accessed by anyone, including those who are not registered with Twitter. However, the tweets are also displayed to the so-called followers of the respective user if he or she is logged in. Followers are other Twitter users who follow the tweets of a user. Furthermore, Twitter enables the addressing of a broad audience via hashtags, links or so-called “re-tweets”.

Via the Twitter component, Twitter always receives information about visits to this website if the person concerned is logged on to Twitter at the same time at the time of the visit; this data collection and forwarding takes place regardless of whether the person concerned clicks on the Twitter component or not.

If the visitor of this website does not want such information to be sent to Twitter, this can be prevented by logging out of the Twitter account before accessing the website.

Twitter is operated by Twitter, Inc. 1355 Market Street, Suite 900, San Francisco, CA 94103, USA. The applicable data protection regulations of Twitter are available at Further information about the Twitter buttons can be found at

Use and application of YouTube

The data processor has potentially integrated components from YouTube on this website. YouTube is an Internet video portal that enables so-called video publishers to post video clips free of charge and other users to view, evaluate and comment on them free of charge.

Each time a page of this website on which a YouTube component (YouTube video) has been integrated is called up, the visitor’s Internet browser is automatically prompted by the respective YouTube component to download a display of the corresponding YouTube component from YouTube. As part of this technical process, YouTube and Google are informed which specific subpage of this website is visited by the person concerned. If the website visitor is logged in to YouTube at the same time, YouTube will recognize which specific subpage of this website is visited by calling up a subpage containing a YouTube video. This information is collected by YouTube and Google and assigned to the respective YouTube account of the person concerned.

If the visitor of this website does not wish this information to be transmitted to YouTube and Google, the transmission can be prevented by logging out of the YouTube account before calling up this website.

The operating company of YouTube is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. YouTube, LLC is a subsidiary of Google Inc, 1600 Amphitheatre Pkwy, Mountain View, CA 94043-1351, USA.
