Techniker Krankenkasse (TK) wants to use its website to provide interested parties and insurees with comprehensive, useful and knowledgeable information about services, benefits, contributions and health topics and offer TK’s insurees and business partners the best possible online service from a modern service provider.

Techniker Krankenkasse’s data protection policy is presented in the following.

This data protection policy informs users about the type, scope and purpose of the personal data collected and used by the responsible provider on this website (hereinafter referred to as the "offer"). The legal basis for data protection is contained in the EU General Data Protection Regulation (GDPR), the Sozialgesetzbuch (SGB) [German Social Security Code] and the Bundesdatenschutzgesetz (BDSG) [German Federal Data Protection Act]. TK only collects and uses your personal data in compliance with these provisions. Such personal data includes all information related to an identifiable or identified natural person. This includes your health insurance number, for example.

We are committed to continuously further developing and improving our website and offerings. These developments may necessitate changes to this data protection policy. We recommend that you periodically visit this website in order to keep up to date on our policy.

1. Processing and retention period of your data on

1.1 Scope of personal data processing

When personal data is collected on this website, it is collected either on the basis of your express consent (Art. 6(1) Sentence 1(a) GDPR), to comply with legal obligations to which TK is subject (Art. 6(1) Sentence 1(c) GDPR), to perform tasks in the public interest or in the exercise of official authority vested in TK (Art. 6(1) Sentence 1(e) GDPR), or to safeguard the legitimate interests of TK (Art. 6(1) Sentence 1(f) GDPR). The data is stored for as long as it is necessary for the purpose for which it was collected and provided that statutory retention periods do not prohibit its deletion.

  • Informational use

    You do not have to provide any personal data if you simply want to obtain information on about a particular topic and do not log in or register on the website or otherwise provide us with information.

    In case of such an "informational use", we only collect the data transmitted by your browser in order to enable you to visit the website. This data comprises:

    IP address
    Date and time of request
    Time zone difference from Greenwich Mean Time (GMT)
    Contents of the request (specific page)
    Access status/HTTP status code
    Volume of data transferred in each case
    Referrer URL
    Operating system and its interface
    Language and version of the browser software.

    The logged data is used exclusively for data security purposes, in particular to prevent attempts to hack into or attack our web server (Art. 6(1) Sentence 1(f) GDPR). The data is neither used to create individual user profiles nor passed on to third parties and is deleted no later than 90 days afterwards. We reserve the right to statistically evaluate anonymised data records.

    Please also refer to the information on analytical tools in Section 4 of this data protection policy.

  • Use of service offers

    For some TK online services, we need personal data to be able to provide the services. If you want to utilise one of these services, we only collect and store the data required to provide the service. The stored data will exclusively be used for the specified purpose.

    If you want to use the TK-Klinikführer [TK Hospital Guide], we will need you to enter a postal code or city in order to inform you about hospitals in your vicinity.

    What data TK collects, stores and uses for a specific service offer can be seen in the individual input form for that service. Further information on data collection and data processing can be found in the explanations and terms for each service offer.

    You can register or deregister on your own initiative at any time for any TK service offer that requires registration.

  • Participation in contests and sweepstakes

    Contests and sweepstakes are offered on the TK website from time to time. TK stores the personal data of the entrants that is necessary to run the contest or sweepstakes. For example, TK needs an address in order to be able to send prizes. The data is only passed on to third parties if it is necessary due to the type of prize or presenting the prize. For example, if a contest is held on the TK website together with a cooperation partner who will be sending the prizes directly.

1.2 When will my data be deleted?

TK deletes personal data

  • if the users revoke their consent to having the data stored;
  • if the data is no longer required;
  • if storage of the data is not permitted for other legal reasons.

2. Communication channels with TK

2.1 Password-protected online offers from TK

On the TK website, there are password-protected areas for various offers where particularly sensitive data is collected. More detailed information can be found in the respective terms of use and data protection policies.

The programs used for entering passwords log the following data for each login error and each time a password is blocked:

  • the username.

This data is stored on the TK web server.

2.2 E-mail communication

In certain cases, we reply to customer enquiries by postal mail even if an enquiry has been sent to us by e-mail. This is always the case if our reply contains social data. We regret that for legal reasons, no other option is available at this time. As soon as a more broad-based secure technology becomes available that guarantees the highest possible data security, we will be happy to answer your service enquiries by e-mail as well.

2.3 Newsletter

The data you provide when subscribing to a newsletter will only be used to personalise the newsletter and will not be forwarded to third parties. Providing this information is voluntary. We perform anonymised tracking for statistical purposes.

3. Information about cookies and data stored in the browser

Like many other websites, the TK website also uses "cookies". Cookies are small text files stored on your computer. They contain information about your visit to our website that is transmitted to TK. Cookies are usually set or read automatically each time you visit

Important note
No data is stored in the cookies that allows personally identifiable information to be traced to any person visiting our website. The information saved in the cookies is stored separately from any other data provided to us. We do not merge this data with other data sources.

This website uses session cookies and persistent cookies. The term "session" here refers to an Internet session that ends at the latest when the web browser is closed.

Click here to change your privacy settings.

3.1 Session cookies

Session cookies are used to save the session data. Session cookies store a "session ID" which is used to assign various requests from your browser to a session. This feature allows your computer to be recognised again when you return to the website.

A session cookie expires at the end of each session. That means that the cookie becomes invalid and can no longer be used as soon as you close the browser completely. The same happens if you are not active on the TK website for more than 30 minutes.

3.2 Persistant cookies

In contrast to session cookies, persistent cookies are stored for a period of up to 6 months. They remain on the computer even after the current visit is over, unless they are intentionally deleted. In addition, persistent cookies contain a predefined expiry date. After that date expires, the cookies are automatically deleted.

TK uses persistent cookies for statistical purposes, for example, in order to identify what content of the TK website is in particularly high demand. This is an important tool that helps us continuously improve for you. A personally identifiable reference to the user is not created in the process.

3.3 Deletion

You can delete cookies set by TK at any time in your browser. However, please note that your personal settings for using are also stored in the cookies. Therefore, if you delete these cookies, your settings will also be reset and you may not be able to use all the features and functions of our website.

4. Analytical tools

4.1 General information

We analyse the usage behaviour of visitors to our website in pseudonymised form, i.e. without being able to trace any personally identifiable information about the visitor. The findings and information we obtain this way helps us to improve the TK website and conduct market analyses.

4.2 Web tracking

TK uses the web tracking method to analyse usage behaviour. This means that TK records which of its websites have been visited and how often. For this purpose, TK sets cookies that expire after 180 days.

TK has commissioned Webtrekk GmbH as the service provider for conducting the usage analysis. The TÜV Saarland technical inspection association has certified Webtrekk GmbH as a service provider for data protection with regard to web monitoring software.

When you visit our website, your browser transmits certain information to us. Webtrekk GmbH stores this data exclusively on its server in Germany. The following data are collected:

  • Time of access 
  • Technical data about your browser and end device, such as operating system, browser, language setting, screen resolution
  • Information about the content, features and functions used, such as page names, campaigns, link clicks, logins, form sections
  • Your IP address is not transferred to Webtrekk.

4.3 Conversion tracking

TK uses conversion tracking to analyse online advertising campaigns. This means that TK tracks how many users reach the website via an online advertisement. The information obtained in this way allows us to generate statistics about our online advertising campaigns. The analysis is only conducted in an aggregated form, so that it is not possible to determine any personally identifiable information about you.

To implement the conversion tracking, TK works together with Adform, a provider that measures our online advertising campaigns. For conversion tracking, TK uses persistent cookies that expire in 60 days.

4.4 Personalisation of website content using Adtelligence Platform software from ADTELLIGENCE GmbH 

On our website, we use the Adtelligence Platform software from ADTELLIGENCE GmbH ( This is used for targeting specific groups with the aim of personalising our online business.  For this purpose, data of website visitors is recorded and assigned to specific target groups by means of cookies and tracking pixels. The target group-specific characteristics are recorded by ADTELLIGENCE, transmitted to the system in anonymous form and stored on servers in Germany. On this basis, pages or contents that are displayed to you are controlled in order to present you with personalised and relevant website content. We will not forward this information to third parties.

4.5 Retargeting

On, we use the retargeting technology from Adform. In online marketing, retargeting is a process in which visitors to a website are identified and are then shown targeted advertising on other websites. For retargeting, TK uses persistent cookies that expire after 90 days. In the case of retargeting as well, the data is only collected in pseudonymised form.

5. Integration of third-party services

Google Maps

We use Google Maps API to visually display interactive maps. When these maps are used, Google also collects, processes and uses data about the usage of the map functions.

Admiral Cloud

We have integrated video files on our website for informational purposes.  These videos are provided on the AdmiralCloud platform.  When the videos are accessed, data is transferred from the user's browser to the AdmiralCloud server.  The data is transferred as soon as the link is clicked on.

The data collected by the AdmiralCloud server includes details on how the user uses the AdmiralCloud services, the IP address, data on the browser type, browser language, date and time of viewing and the URL of the page on which the video is stored, as well as cookies that can be used to uniquely identify the user’s browser, but which are only used to manage the service.

6. System security

We maintain up-to-date technical measures to ensure data security. These measures are particularly intended to protect your personal data from unauthorised access by third parties. We adapt our protection and security mechanisms to the current state of the art. 

If you are asked to enter personal data in one of our online offers, the data is always transferred using TSL encryption. The purpose of this encryption is to prevent any unauthorised party from gaining possession of your data.
