GDPR).

a.    Uses (Art. 6 para. 1 a GDPR / §15 para. 3 German Teleservices Act)

Tag Management
Tag management is used to manage tracking tools in websites. For this purpose, a tag is defined for each page. The marker can then be used to determine which tracking tools are to be used for this page. The tag management allows tracking to be controlled in a targeted manner so that the tools are only used where they make sense.

Market research / reach measurement the aim of reach measurement is to statistically determine the usage intensity and the number of users of a website as well as to obtain comparable values for all connected offers. At no time are individual users identified. Your identity is always protected. 

Profiles for the need-based design of the web portal
In order to be able to constantly improve the web pages, we create so-called clickstream analyses. The clickstream corresponds to your movement path on the web pages. The analysis of the movement paths gives us information about the usage behaviour on our websites. This allows us to identify possible structural errors in the web pages and thus improve the web pages so that the web pages can be optimized to your needs. At no time are individual users identified.

Profiles for personalized recommendations
T-Systems plays out customized, personalized, action- and click recommendations for offers, services or products. For this purpose, the service provider creates a pseudonymous profile of the services and websites you call up on the Internet and assigns this to categories. You will be shown content or notes matching your profile. At no time are individual users identified or personal data used for the profile.

Measurement pixels
Measuring pixels are usually only 1×1 pixel sized images and are transparent or created in the color of the background so that they are not visible. If a web page containing a measuring pixel is opened, this small image is downloaded from the provider's server on the Internet, where the download is registered. Thus the provider of the process can see when and how many users requested this measuring pixel or visited a website. Furthermore, the provider can determine whether JavaScript is activated in the browser or not. If JavaScript is activated, further information such as browser information, operating system, screen resolution can be recorded. Usually this function is realized by a JavaScript call, but the term measuring pixel is still used. 

JavaScripts are used to call up the application and transfer the collected parameters to the respective service provider/measuring pixel provider.
