Privacy Policy

Our data privacy statement, sets out how we handle personal data. We are aware of the importance to users of how personal data are handled and we assure you that we observe all relevant legal requirements. We consider the protection of your privacy to be of paramount importance. For this reason, compliance with the legal requirements on data privacy is, for us, a matter of course.

Group-Oriented Data Privacy

To which extent and in which form we process and save personal data depends on the concerned group of persons. Thereby we distinguish as follows: publisher, advertiser/merchant and user.

Publishers are website operators, who use YieldKit services by implementing the YieldKit code to activate and integrate a JavaScript into their website. The management and use of the YieldKit account takes place over a web-based portal which is accessible through a browser-login.

Advertisers/merchants are advertisers who use the YieldKit technologies to connect with publishers who use YieldKit services. Upon request, the management and use of a YieldKit account can take place over a web-based portal which is accessible through a browser-login.

We define partners as both groups, advertisers/merchants and publishers.

Users are website visitors, who use YieldKit’s publisher websites.

Who is YieldKit and what does the company offer

YieldKit is the leading Performance Marketing Aggregator in the German market. Based in Hamburg, the company connects publishers and advertisers in a unique way.

YieldKit technology enables publishers to connect their websites with intelligent monetization solutions. With just one integration publishers can automatically monetize their content and collect e-commerce behavioural data to optimize and aggregate new revenue streams for their business. YieldKit is the perfect solution for publishers and advertisers. Publishers are able to increase their revenue by connecting with more than 45.000 advertisers worldwide, while merchants increase their sales with high quality traffic, provided by YieldKit contextual solutions.

From the user perspective and under terms of data privacy the following YieldKit technology elements are relevant:

  • 1. Tracking of ad displays and clicks on advertising media, tracking of sales transactions
  • 2. Aggregated reporting (user-segmentation) in respect to e-commerce and behavioural data of the user. No personally identifiable information is given, just an aggregated and segmented report.

In this context no personal data, like names or e-mail addresses, identifiable to a natural person is ever visible. Which user data is visible and stored is defined in the section “Processed data, data sources and purpose of use, user data”.

Like almost all website operators, we use analytical tools in the form of tracking software to ascertain the number of users using our website and how frequently they visit.

To enable us to optimize our website and our service, we use Google Analytics, which is a web analysis service provided by Google Inc. (“Google”). Google Analytics uses what are known as “cookies”: these are text files stored on your computer and used to analyse your website usage. The information generated by the cookie about your use of this website (including your IP address) will be sent to a Google server in the USA and stored there. However, if IP anonymisation is enabled on this website, within member states of the European Union, or in other states that are party to the agreement on the European Economic Area Google first abbreviates your IP address. The full IP address will only be transmitted in exceptional circumstances to one of Google’s servers in the USA, where it will then be abbreviated. Google will use this information on behalf of our website operator to analyse your use of the website in order to compile reports about website activities for the website operator and to perform other services connected with the use of the website and of the Internet. The IP address transmitted by your browser as part of Google Analytics will not be merged or combined with other data by Google. You can prevent cookies from being stored by applying the appropriate settings in your browser software; please note, however, that in this case you may not be able to use all of the functions of this website to their full extent.

You may also prevent Google from collecting data generated by the cookie referring to your website usage (including your IP address), and from processing these data by downloading and installing the browser plug-in available from the following link As an alternative to the browser add-on or within browsers on mobile devices, please click on this link to prevent Google Analytics from collecting data in this website in future (the opt-out only works in this browser, and only for this domain). This stores an opt-out cookie on your device. If you delete your cookies in this browser, you need to click on this link again. Further information is available at or at (general information on Google Analytics and data protection).
