These include, for example, name, and address, postal address, e-mail address but also the IP address or license plate number. Other information that cannot be directly linked to your person (e.g. version and brand of your browser, operating system of your computer) does not fall into this category.

In principle, you can use our Internet pages without disclosing your identity. However, if you order a product or wish to register for one of our events, we will ask you for your name and other personal data in order to process your order. The employees of the GDCH Office who are concerned with the technical, commercial or content-related processing of these systems will have access to your personal data. All employees of the GDCh are obliged to comply with the obligation to maintain confidentiality and data protection. We take precautions to protect your data and to prevent misuse from outside sources. Measures such as SSL encryption, firewalls, hacker defense programs and manual security precautions are applied.

When you access our website, we also store additional information (e.g. browser type, network, provider, date, time, pages viewed, jump address from other web servers, etc.) that may allow your person to be identified. However, we do not carry out any personal utilization of this data. The data records are evaluated only statistically, to optimize our offer and to simplify the user guidance.

The GDCh uses the free software Matomo on its own GDCh web space in Germany with IP address anonymization to collect statistical information on website access. The anonymization or masking of your IP takes place as soon as the data arrives and before storage or processing takes place. A personal reference cannot be established. Cookies are not set.

Nevertheless, there is the possibility to object to the data collection (opt-out):

This website uses Google Analytics, the web analysis service of Google LLC (privacy policy of Google). Information about your use of this website will generally be transmitted to and stored by Google on servers in the United States. However, if you choose to have your IP address anonymized on this website, Google will first delete your IP address from Google's database within European Union member states or other signatory states to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. On behalf of the GDCh, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services to website operators relating to website activity and internet usage. The IP address transmitted by your browser as part of Google Analytics is not combined with other data from Google.

The GDCh uses Google Analytics with IP address anonymization. The anonymization or masking of your IP takes place as soon as the IP addresses arrive in the Analytics data collection network and before the data is stored or processed. A personal reference can then no longer be established.

There are two possibilities to contradict the collection of your GDCh website usage via Google Analytics or to limit the collection:

(1) You can prevent Google from collecting your data relating to the use of the website (including your IP address) and from processing this data by Google by downloading and installing the browser plug-in available at the following link:

(2) You can prevent the storage of cookies by setting your browser software accordingly.

YouTube videos

On the GDCh website, videos about YouTube are occasionally included in the extended data protection mode. YouTube uses cookies to collect information about visitors to its website. These cookies are used to collect video statistics, to prevent fraud and to improve user-friendliness. Embedding the videos also leads to a connection being established with the Google DoubleClick network. When you start a video, it triggers further data processing. The GDCh has no influence on this. For more information about privacy at Google and YouTube, please see the privacy statement:


The Internet pages of the GDCh contain links (connections) to the websites of other providers. We have no influence on the content and design of these websites, in particular on subsequent changes to their content. We also have no influence on whether the operators of these websites comply with the data protection regulations according to DSGVO. Links may lead to servers that are not located in Europe and are therefore not subject to the EU DSGVO.

Social media

You can read the content posted by the GDCh on Twitter and Facebook without being registered on Twitter or Facebook. Since these services are not operated by the GDCh, we have no influence on whether and how your use of these services is logged and whether data is collected or forwarded. Please inform yourself on the websites of the respective providers about the data protection measures applied there.

E-mails to the GDCh office

We expressly point out that the GDCh employees at the office have usually set up at least one colleague with access to their e-mail inbox so that incoming e-mails can be processed quickly even in case of absence. If you would like to send a confidential message to a specific member of staff, please make sure that the desired person is present beforehand.

Newsletter Tracking

The newsletters of the GDCh contain so-called Zählpixel. A pixel is a miniature graphic that is embedded in e-mails sent in HTML format to enable recording and analysis. This allows statistical evaluation of the success or failure of online marketing campaigns. Based on the embedded pixel-code, the GDCh can recognize if and when an e-mail was opened by an affected person and which links in the e-mail were accessed by the affected person.

Such personal data collected via the pixel-code contained in the newsletters are stored and evaluated by the data controller in order to optimise the newsletter dispatch and to adapt the content of future newsletters even better to the interests of the person concerned. This personal data will not be passed on to third parties. Affected persons are entitled at any time to revoke the relevant separate declaration of consent submitted via the double opt-in procedure. After a revocation these personal data will be deleted by the person responsible for the processing. The GDCh automatically interprets a de-registration from the receipt of the newsletter as a revocation.

Passing on personal data to third parties

WWe only use your personal data for orders or registrations within the GDCh. We do not pass your data on to third parties unless you register for an event which is carried out by the GDCh together with other cooperation partners or using external service providers. In this case we usually pass on your registration data to our cooperation partners. The data will only be passed on to external service providers if this is necessary for the performance of the service (so-called order data processing). If data is passed on to third parties in accordance with the regulation explained above, we commit them in writing to comply with the statutory provisions of the EU-DSGVO.

If you register for an event from an event series which is organised by changing national or international organisers, the GDCh may in individual cases pass on contact data to the next organiser within this event series so that you can be informed about the successor event. We observe the principle of data economy and forward only selected data (usually name and e-mail) to the chairman of the following event.

Insofar as we are obliged to do so by law or court order, we will forward your data to bodies entitled to receive such information.

At some points on our website you can register in forums or subscribe to mailing lists and databases. Unless otherwise specified, the contributions there are accessible to everyone. You should carefully check your contributions before publication to ensure that they do not contain any information that is not intended for the public. You must reckon with the fact that your contributions are registered in search engines and become accessible also without purposeful call of our offer world-wide. The deletion or correction of such entries can often not be enforced by foreign operators.

Children and adolescents

Children and young people under the age of 18 should not transmit any personal data to us without the consent of their parents or legal guardians. They require the consent of their parents or legal guardians to order our products.

As part of the student prize, the GDCh receives the addresses of the prize-winning students from the schools so that they can be personally invited to free GDCh membership. There will be no further use of these addresses.
