On the processing of personal data

As a rule, you can use the DUH website without providing any personal data. If you wish to donate, contact us or make use of our information services, you will be asked to enter the data necessary for processing. For example, we may ask you for your name and some other personal information relevant to the type of use. Mandatory information is marked separately in each case. Your data will come to us via an SSL-secured connection and will be stored on specially protected servers in Germany. Access to it is only possible for a few specially authorised persons who are involved with the technical or commercial support of these servers or are entrusted with the internal work processes. These persons have been instructed in data protection law and are bound to data secrecy. Under no circumstances will your personal data be passed on to third parties without your express consent. When entering your personal data, you will also be informed about the use of your personal data and must ask your consent for this.

We would also like to point out that data transmission over the Internet (e.g. communication by e-mail) can be subject to security vulnerabilities. A complete protection of the data against access by third parties is not possible, it is therefore also your responsibility to protect your data by encryption or in any other way against misuse.

In the following, we would like to give you an overview of how we ensure the protection of your personal data when accessing our website and which types of personal data we process for which purposes and to what extent.

This information (server log files) includes, for example, the type of web browser, the operating system used, the domain name of your Internet service provider and the like. In addition, the IP address is transmitted and used to use the service you have requested. This information is technically necessary for the correct delivery of content requested by you from websites and is mandatory when using the Internet.

These log file data are deleted by us within 7 working days after completion of the use process. The legal basis for data processing is Art. 6 Para. 1 S. 1 f) DSGVO.

Integration of YouTube

Our website uses plugins from the YouTube page operated by Google. The site is operated by YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA.

When you visit one of our pages equipped with a YouTube plug-in, a connection is established to the YouTube servers. This will tell the YouTube server which of our pages you have visited.

You will also find an opt-out option for each presentation of the application. These are cookies for recording the usage behaviour of our website and cookies that are used for advertising purposes.

Use of cookies to record user behaviour (tracking)

The use of tracking cookies enables us to recognize users when they access our website again and to assign usage processes to an internally assigned code number (pseudonym). In this way, we can record repeated visits to our website and analyse them in context.

Specifically, the following tracking cookies are used:

Google Analytics

This website uses Google Analytics, a web analytics service provided by Google Inc. (Google). Google Analytics uses cookies, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website will generally be transmitted to and stored by Google on servers in the United States. However, due to the activation of IP anonymisation on this website, your IP address will be shortened by Google in advance within Member States of the European Union or in other Contracting States to the Agreement on the European Economic Area. Only in exceptional cases is the full IP address transmitted to a Google server in the USA and shortened there. Google will use this information on our behalf to evaluate your use of the website, to compile reports on website activity and to provide us with other services 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.

You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website.

Google Ad Grandts / Google Adwords Tracking

 We use the offer of Google Ad Grants, the offer for NGOs of Google Adwords, to draw attention to our important topics with the help of advertising media (so-called Google Adwords) on external websites. These advertising media are delivered by Google via so-called "Ad Servers". Ad server cookies are used to evaluate performance parameters such as ad impressions, clicks and conversions. This enables us to determine how successful the individual advertising measures are in relation to the data of the advertising campaigns. If you access our website via a Google advertisement, Google Adwords stores a cookie in your PC. These cookies usually lose their validity after 30 days and are not intended to identify you personally. The following analysis values are usually stored for this cookie:

  • Unique Cookie ID
  • Number of ad impressions per placement (Frequency)
  • Last Impression (Relevant for Post-View-Conversions)
  • OptOut information (marking that the user no longer wishes to be addressed)


These cookies enable Google to recognize your Internet browser. If a user visits certain pages of an AdWords customer's website and the cookie stored on their computer has not yet expired, Google and the customer may recognize that the user clicked on the ad and was directed to that page. Each Adwords customer is assigned a different cookie. Cookies cannot therefore be traced via the websites of Adwords customers. We ourselves do not collect and process any personal data in the aforementioned advertising measures. We only receive statistical evaluations from Google. On the basis of these evaluations, we can identify which of the advertising measures used are particularly effective. We do not receive any further data from the use of the advertising media, in particular we cannot identify the users on the basis of this information. The legal basis for the storage of cookies by Google is the consent given (Art. 6 Para. 1 S. 1 lit. a DSGVO).

Due to the marketing tools used, your browser automatically establishes a direct connection with the Google server. Please note that data processing by Google may take place outside the European Union. Google has submitted to the EU-US Privacy Shield, In addition, we have no influence on the extent and further use of the data collected by Google through the use of this tool and therefore inform you according to our state of knowledge:

Through the integration of "tracking tools" Google receives the information that you have called the corresponding website of our Internet presence, or that you have clicked on an advertisement from us. If you are registered with a Google service, Google can assign the visit to your account. Even if you are not registered with Google or have not logged in, it is possible that the provider may find out and store your IP address.
