T-Systems International GmbH attaches great importance to protecting your personal data. We always inform you what personal data we collect, how your data is used, and how you can influence the process.

1.    What data is recorded, how is it used, and how long is it stored?

a)    Technical characteristics: When you visit our websites, the web server temporarily records the domain name or your computer’s IP address, the file requested (file name and URL) by the client, the http response code, and the website from which you are visiting us. 
The recorded data is used solely for data security purposes, particularly to protect against attempted attacks on our web server (Article 6 (1f) GDPR). We do not use it to create individual user profiles nor do we share this information with third parties. It is erased after seven days at the latest.

2. Data control when clicking on external links or links to social media platforms

Some pages contain links to other websites as well as pictograms of social media networks (such as Facebook, Google, Instagram, Twitter, Pinterest, Xing or LinkedIn).

Links to other websites are marked with the following symbol . By clicking on these links or the corresponding pictogram, you will be directed to external information pages or to the company page of the selected platform. The social media platforms as well as the third-party content providers that can be reached via the pictograms provide these services and the processing of their data under their own responsibility. To ensure that you have full data control, the external links and pictograms used only establish direct contact between the respective social network and the visitor when you actively click on the button. 

By clicking on the external links and the links of the pictograms, (Art. 6 para. 1a GDPR) the following data may be transmitted to persons responsible for the externally linked websites or the social media providers: IP address, browser information, operating system, screen resolution, installed browser plug-ins such as Adobe Flash Player, the previous page when you followed a link (referrer), the URL of the current page, etc.

Explanations and definitions
We want you to enjoy using our websites and take advantage of our products and services. We have an economic interest in ensuring this is the case. We analyze your usage habits on the basis of anonymized or pseudonymized data so you can find the products that interest you and so we can make our websites user-friendly. Deutsche Telekom or its contract data processors create usage profiles that comply with the legal requirements. This information cannot be traced back to you directly. The following information is intended to provide you with general information on the various purposes of processing data. The cookie message displayed when visiting our webpages gives you the opportunity to permit or reject the use of cookies. Cookies that are strictly necessary to provide the web service cannot be rejected (see explanation at 1. above).

Tag management (strictly necessary)
Tag management allows us to manage the use of tools on the different web pages of our web portal. A tag is set for each page to do this. The tag content determines which tools will be used for this page. Tag management is used to assure that the tools are in each individual case only used where appropriate.

Market research / Reach measurement (opt-in)
Reach measurement provides statistics on a website’s usage intensity and the number of users, along with comparable figures for all the connected services. Market research is designed to learn more about the target groups that use services or applications and view advertisements. Individual users are not identified at any time. Your identity is always protected. 

Profiles for a user-geared presentation of the web portal (opt-in)
The compilation of clickstream analyses assists us in continuously improving our web pages. The clickstream corresponds to your movement on the websites. Analyzing the movement provides us with an insight into usage habits on our websites. This allows us to detect any existing structural deficiencies in our web pages and thereby improve them accordingly. 

Profiles for personalized recommendations (opt-in)
Deutsche Telekom would like to offer you individually targeted and personalized take-action and click recommendations for special offers, services or products.  This involves our service providers compiling a pseudonymous profile about the services and websites accessed by you and assigning categories to the profile. The system displays content or information that matches your profile.

c)    Marketing cookies/retargeting

By suppressing marketing cookies, you will continue to see the same number of ads, but they may be less relevant for your interests.

To cooperation partners who, on their own responsibility, provide services for you or in conjunction with your Deutsche Telekom contract. This is the case if you order services of these partners from us, if you consent to the involvement of the partner, or if we involve the partner on the basis of legal permission.
