Privacy Policy

Privacy policy

Privacy provisions made by DKMS gemeinnützige Gesellschaft mbh.


The collection of personal data

DKMS collects, processes and uses your personal data only to the extent permitted by law in order to find suitable bone marrow/ stem cell donors and to contact you. DKMS is registered as a non-public, responsible entity with the competent commissioner for data protection in the State of Baden-Württemberg. In accordance with Section 38, Para. 2 of the German Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG), the state commissioner for data protection maintains a register of automated data processes subject to notification pursuant to Section 4d and monitors compliance with data protection law. If you register as a donor on our website, subscribe to a newsletter, donate money, or use other online forms, your data is transmitted to us in encrypted form in order to prevent access by unauthorized third parties. We always store your data on specially protected servers. Access to personal data is restricted to only a few specially authorized employees of DKMS, all of whom are familiar with the relevant privacy policy regulations.


Disclosure of your personal information to third parties

We process your data only for the purpose of matching stem cell donors with patients. Your donor information as well as the results of the tissue typing carried out for you are transmitted in anonymized form to national and/or international bone marrow donor registers. This means that only data that is relevant for the important decisions in the donor search is transmitted. This mainly includes your donor number, gender, date of birth, tissue types, the number of previously conducted typings, and your donor status – whether you are available or not. Names, addresses, or similar identifying information is not transmitted. In order to fulfill our tasks, we also need to work with service providers who may also receive personal information for the above purpose. These service providers are contractually obligated by DKMS to use personal data that they receive in this context only for the permitted purpose. We hereby assure you that we do not sell or lease your data to other companies or organizations. Under no circumstances will we use your email address or other data without your approval for any other purposes for which you have not granted your consent.


Storing IP addresses on this website

In order for you to access DKMS websites, it is necessary to temporarily register your IP address. We use this information to evaluate the use of our website and further optimize it for you. The IP address is the globally valid, unique identifier of a computer and consists of four strings of digits separated by decimal points. As a private user, you will generally not use a consistent IP address since these are assigned on a temporary basis by your provider for one session. However, in principle it is possible to uniquely allocate user data via this attribute using static IP addresses. DKMS assumes no responsibility for services provided by third parties that are linked to the DKMS websites, such as Twitter or Facebook. Such third parties have no way of matching a user´s IP address with other personal data collected through the DKMS websites. For more information about data collection by third-party providers, see their websites.


Use of Google Analytics and saving cookies

DKMS uses Google Analytics, a web analysis service offered by Google Inc. (“Google“), on this website. Google Analytics uses so-called “cookies“ – text files that are saved on the user´s computer and permit an analysis of how visitors use the website. The information obtained through the cookie regarding the use of this website (including the user´s IP address) is transmitted to a Google Inc. server in the USA and saved there. Google uses this information to evaluate the use of the website by its visitors, to compile reports on the activities of the visitors on the DKMS websites, and to provide other services related to the use of the website and the internet. Google may also transmit this information to third parties if required by law or if third parties process this data on behalf of Google. Google guarantees that your IP address will not be linked to other Google Inc. data in any way. For more information on the terms of use and privacy policy, see: or We would like to point out that Google Analytics has been supplemented on this website by the code „gat._anonymizeIp();“ to ensure an anonymized collection of IP addresses (so-called IP masking). You can prevent cookies from being installed on your computer by adjusting your browser settings; however, we would like to point out that you may not be able to make full use of all functions of this website in this case. By using this website, you agree that Google may process the data collected about you in the way described above and for the purpose indicated above. In addition, you can prevent the collection of data generated by the cookie and related to your use of the website (including your IP address) by Google as well as the processing of this data by Google by downloading and installing the browser plug-in available under the following link: (


Use of Google AdWords

DKMS gemeinnützige Gesellschaft mbH also uses the free conversion tracking function offered by Google AdWords on this website. Google is committed to protecting the data of its customers and users in this context. If a user clicks on an ad, Google places a cookie on that user´s computer, which expires after 30 days. Google does not associate a user´s search activity with his or her ad click history. Furthermore, Google does not collect or track any personally identifying information and does not disclose personal information to third parties. Users who do not wish to participate in tracking can deactivate Google´s conversion tracking cookie using their preference setting in their web browser. These users will not be included in the conversion tracking statistics.


Use of Google Site Search

DKMS gemeinnützige Gesellschaft mbH uses Google Site Search on this website. Google´s privacy policy regulations apply for the use of the search field on this website.


Use of AdClear

We use the services of AdClear GmbH (“AdClear”) to collect statistical data for campaign tracking, which helps us to constantly improve our website. So-called “cookies” (text files that are saved on your computer) are used for this purpose. The data is collected only in pseudonymized form. Personal data is not transmitted to AdClear. AdClear GmbH is certified by TÜV Saarland for data protection in the area of campaign tracking systems. You can exclude yourself from the collection of campaign tracking data by AdClear. For this purpose, the domain will set a cookie with the name “adclearoptout.” This exclusion applies as long as you do not delete the cookie. The cookie is set for the named domain, per browser and per user of a computer. If you access our website from multiple devices and browsers, you must exclude yourself from data collection by AdClear separately on each device and browser. Opt out of AdClear campaign tracking.


Use of Facebook Website Custom Audience

Our website uses the retargeting technology “Website Custom Audience” offered by the social network Facebook, which is operated by Facebook Inc., 1601 S. California Avenue, Palo Alto, CA 94394, USA (“Facebook”). This technology enables us to show Facebook members who have already visited our website relevant information about DKMS on Facebook as well, via the Facebook ad network. For this purpose, so-called “Facebook retargeting pixels” are incorporated into our websites. These pixels allow Facebook to record you as a visitor to our websites, using a pseudonym, and to use the data as the basis for our Facebook ads on Facebook. Your personal data is not collected or stored for this purpose, and we therefore cannot identify you on Facebook. For more information on data protection and your relevant setting options, see: and You can refuse the use of Facebook Website Custom Audiences in the future via and


Use of social plug-ins

Our website uses social plug-ins from various social networks. If you visit one of our websites that contains a social plug-in, your browser creates a direct link to the servers of the social network. The content of the plug-in is transmitted from the social networks directly to your browser and integrated into the website. When the plug-in is active, the social networks receive information that you have visited a certain website page. If you are logged in on one or more social networks, they can associate the visit with your account. If you interact with the plug-ins, for example by clicking a “like” button or posting a tweet, the corresponding information will be transmitted by your browser directly to Facebook and Twitter and saved there. Please read the privacy policies of the relevant social network platforms for more information regarding the purpose and scope of data collection and further processing and use of the data by the social networks, as well as your rights and setting options for protecting your privacy.
