Notes on data privacy


Telekom Deutschland 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 (Art. 6 (1) f GDPR). We do not use it to create individual user profiles nor do we share this information with third parties. It is erased after 7 days at the latest. We reserve the right to statistically analyze anonymized data records.

b) User surveys/customer feedback with KE Questionnaire: These websites use the service from KE Questionnaire, to provide customer surveys. Website ratings and your feedback can be surveyed (Art. 6 (1) a GDPR). Our customers’ opinions and improvement suggestions crucially help us improve our websites. Only anonymous information is processed and there is no way of tracing the sender. Personal data or personally identifiable data is not transferred at any time. We store and analyze the data for add storage period. 

There are two different ways of conducting the surveys:

I) The feedback button on the website. You can use this button at any time to provide us with your feedback. No data is transferred unless you use this function.

II) An active feedback survey can also be displayed on the website. You can reject this survey or cancel it at any time. Answers are only sent once you have completed the survey.

2. Data control for the social media plug-ins used

Some web pages may contain social media buttons (e.g. Facebook, Google, Instagram, Twitter, Pinterest, Xing or LinkedIn) you can use to recommend the services of Telekom Deutschland GmbH to your friends and family.

To ensure you retain full control of the data, the used buttons provide direct contact between the respective social network and the visitor only once you actively click on the button (one-click solution).

When the social media plug-in is activated (Art. 6 (1) a GDPR), the following data can be forwarded to the social media provider: IP address, browser information, operating system, screen resolution, installed browser plug-ins (such as Adobe Flash Player), previous website if you followed a link (referrer), URL of the current website, etc...

The next time you visit the website, the social media plug-ins are again provided in the default disabled mode, thus ensuring that no data is transferred during a repeat visit to th

e website. Further information on social media plug-ins is available at: (only in German) and

1-Click Solution (only in German).

3. Will my usage habits be evaluated, e.g. for advertising purposes or tracking?

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.

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.

In connection with your newsletter registration, we also store your registration data (e.g. e-mail address, name, date and time of registration/confirmation of opt-in) so that we can trace and prove the registration at a later date.

Browser Notifications (Web Push)

Browser notifications (web push) If you activate browser notifications for this website through the "Signalize" service, a function of your Internet browser is used to provide the notifications for you. Only anonymous or pseudonymous data is transmitted for sending messages. Depending on the configuration of the website, this can be

Pseudonymous user ID: a randomly generated value (example: 108bf9a85547edb1108bf9a85547edb1), which is stored in a tracking cookie ID.
Pseudonymous digital fingerprints, pseudonymous mobile device identifiers and, where applicable, pseudonymous cross-device identifiers.

Information about opting out for web push notifications for the respective browsers can be found here: Google Chrome, Mozilla Firefox, Opera and Microsoft Edge.

In order to make the browser notifications meaningful for you in terms of content, we use the preferences collected on the basis of a pseudonymous user profile by means of tracking pixels and merge your notification ID with the user profile of the website solely for the purpose of personalised messaging. Tracking technology is also used to statistically analyse notifications on our behalf. This enables us to determine whether a notification has been delivered and, if so, whether it has been clicked on. The data generated in this way is processed and stored on our behalf by etracker GmbH exclusively in Germany and is therefore subject to the strict German and European data protection laws and standards. etracker has been independently audited and certified in this regard and is entitled to bear the ePrivacyseal data protection seal of approval.

The processing of data for the statistical analysis of notifications as well as to better adapt future notifications to the interests of recipients is based on our legitimate interest in personalised direct advertising in accordance with Art. 6 (1) lit. f DSGVO. Since the privacy of our visitors is very important to us, data that may allow a reference to an individual person, such as the IP address, login or device identifiers, are anonymised or pseudonymised as soon as possible. A direct reference to a person is thus excluded. The data will not be used in any other way or passed on to third parties.
