1. General information

Deutsche Telekom AG attaches great importance to protecting your personal data. We always inform you about personal data that we collect during your visit to our websites, how it is used, and how you can influence the process. This data privacy information provides answers to the most important questions.

2. What data is collected and how is it used?

For the provision of our services

Technical characteristics: When you visit our websites, our web servers temporarily record the domain name or IP address of your computer, 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 server, and for statistical analysis. 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.

Cookies: We use cookies for certain services. These are small text files that are stored on your computer. They enable the system to tell if you repeatedly visit websites from the same computer.

Session cookies are cookies that are only saved on your computer for the duration of a single Internet session, in the context of comments to articles and blog posts. They do not contain any personal data.

For some offerings we use persistent cookies that support the authentication of blog comments and are stored on your computer for future sessions. In addition, a persistent cookie is saved when you click the confirmation link to release your own comment. These cookies remain valid until you delete them or until the deletion period configured in your client is reached.

You can set your browser to prevent these cookies being stored or to delete the cookies at the end of your Internet session. However, please remember that in this case you may not have access to the full range of functions offered by our websites. Information on the browser settings can be found at: (German)

Dynamic FAQs: If you use the FAQs and submit a question that is not covered in the pool of available answers, you are prompted to enter your e-mail address. We will only use this e-mail address to send you your answer.

Other personal details such as your name, address, telephone number, or e-mail address will not be collected unless you provide this information voluntarily, for example, in the chat or in web forms.

3. Where is my data processed?

Your data is processed in Germany. Your data may also be processed elsewhere within or outside of Germany, in line with legal regulations.

4. How secure is my data?

We have taken extensive technical and operational precautions in accordance with German law to protect your data against unauthorized access and misuse.

5. Will my data be passed on to third parties, e.g. public authorities?

In certain cases, we are legally obliged to pass on data if requested to do so by a state body. We do not pass on your data to third parties for any other purpose, unless you have given express permission.

6. Will my usage habits be evaluated, e.g. for advertising purposes?

We or companies commissioned by us create usage profiles under pseudonyms, to the extent permitted by law. These can be evaluated for advertising and market research or for designing websites in line with requirements. This information cannot be traced back to you directly. The profile data is not linked to any other information about your person. The following informs you about the processes used on our websites and how you can revoke consent at any time.

Website analysis with Webtrekk:

We use the services provided by Webtrekk GmbH, to record statistical data regarding the usage of the websites and to optimize our services accordingly. Webtrekk GmbH is TÜV-certified for data privacy with respect to web controlling software. As part of your visit to our websites, information that your browser transfers is collected and analyzed. This information is collected by means of a measurement pixel, which is incorporated on each website. A signature is used for recognition purposes. This is made up of various automatically transferred pieces of information from your computer. Webtrekk also uses the following cookies:

  • Session cookie (for session identification; lifespan: one session)
  • Long-term cookie (to detect new/existing customer: 6 months)
  • Opt-out cookie (where users opt out of tracking: 60 months)

Webtrekk GmbH stores the IP address only in abbreviated (anonymized) form and only uses it for session identification, for geolocalization (down to city level) and to prevent attacks. The IP address is erased again immediately so that the recorded data is then pseudonymous.
You can opt out of data processing by Webtrekk at any time under the following link: I want to opt out of Webtrekk tracking!

7. What is conversion tracking and how is it used?

When you click through to our website from a Deutsche Telekom e-mail (such as a newsletter), Teradata (Mapp) saves a cookie on your computer. This cookie becomes invalid after 30 days. No conclusions can be drawn about you as a person.

We use the information collected with the aid of the conversion cookie to create statistics about our conversion rate. This means we find out how many people visited our websites by clicking an e-mail link.

If you do not wish to participate in the tracking process, you can disable cookies for conversion tracking by specifying in your browser settings that cookies from the relevant domain are to be blocked:

8. Data control with the social media plug-ins used

Some of our websites include buttons for social media networks (Facebook Like button, Google +1, Twitter button) that you can use to recommend the services of Corporate Communications at Deutsche Telekom AG to your friends and family.
To ensure that you have full data control, grayed-out images of the respective functions are displayed instead of the actual social plug-ins when you load the website. The exchange of data is not activated until you click the checkmark next to the images, which loads the respective social media plug-ins. An action (such as liking the page) is not activated until you click a second time.
When the social media plug-in is activated, the following data can be forwarded to the social media provider: IP address, browser information, operating system, screen resolution, installed browser plugins (such as Adobe Flash Player), origin of the visitor if you followed a link (referrer), URL of the current web page.
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 the website.
For more information about social media plug-ins, visit (German) or (German).

9. Can I obtain information about my stored data?

You may request, free of charge, information on the scope, origin, and recipients of the stored data as well as the purpose of storage.

10. Can I have data corrected?

You may request that incorrect data be corrected at any time.

11. Where can I find further information regarding data privacy at Deutsche Telekom?

Further information, including information on data privacy in specific products, is available at and under (German).

12. Who should I contact if I have any queries regarding data privacy at Deutsche Telekom?

If you have any queries, please contact our Customer Services department or the Group Data Privacy Officer at Deutsche Telekom AG, Dr. Claus D. Ulmer, Friedrich-Ebert-Allee 140, 53113 Bonn,
