Data protection information on the use of cookies

To make your visit to our website enjoyable and enable the use of certain features, we use cookies on different pages. Cookies are tiny text files that your browser stores on your device as instructed by our website. When a user accesses a website, a cookie may be stored on the user’s device. The cookie contains a distinctive string of characters that enables unique identification of the browser – for instance, when the website is accessed again later.

Description and scope of data processing

First, we use session (temporary) cookies that are automatically deleted when you close your browser. Second, we use what are known as “persistent” (permanent) cookies, which have expiration dates set in the future for your convenience. Cookies may be provided by us or by third parties.

The user data gathered in this manner are pseudonymized. This means that it is not possible to directly associate the data with the accessing user. The data are not stored together with users’ other personal data.

When you visit our pages, an integrated application provides you with all the information available about the cookies we use and your options for preventing the use of cookies by opting out or consenting to their use by opting in.

It is important to note the difference between two types of cookies. First, there are  necessary, functional (essential) cookies. Next, there are cookies used for analytics, personalization and marketing.

Legal basis for data processing

The legal basis for processing personal data using the various types of cookies is outlined below:

  • In the case of essential cookies, processing is lawful under Art. 6, pare. 1f (legitimate interest) and Art. 6, para. 1c (compliance with legal obligations).
  • In the case of personalization, analytics and marketing cookies, processing is lawful with appropriate consent from the user (Section 25 of the Telekommunikation-Telemedien-Datenschutz-Gesetz [TTDSG – German Telecommunications and Telemedia Data Protection Act]) and Art. 6, para. 1a of the EU’s General Data Protection Regulation (GDPR)).
  • In the case of cookies that involve the transfer of data to third countries, processing is lawful with appropriate consent from the user (Art. 49, para. 1, sentence 1a of the GDPR).

Transfer to third countries

If your consent has been given, your data may be transferred to the US, particularly through the use of cookies from third-party providers.

According to a ruling handed down by the European Court of Justice (decision of 16 July 2020, case no. C-311/18 (“Schrems II”)), the US does not offer an appropriate level of data protection. In particular, there is a risk that your data may be processed by US government authorities for purposes of surveillance and monitoring, potentially without judicial redress or the right to an effective remedy.

Purpose of data processing

The purpose of using essential cookies is to enable, and if necessary, simplify use of websites for individuals. Some functions of our website cannot be offered without the use of these cookies. For example, those functions make it essential for the browser to be recognized again after a page change.

The user data collected by means of technically necessary cookies are not used to create user profiles.

Essential functional cookies, analytics and personalization cookies, and marketing cookies are used for the purpose of improving the quality of our website and its content and to present you with personalized content and offers. From those cookies, we learn how the website is used, enabling us to constantly optimize our offering.

Duration of storage

Cookies are stored on the user's computer and transmitted from the computer to our site. Session cookies are automatically deleted once you leave our website. Other cookies remain stored on your device until a specific period, which may vary, has expired or until you delete them.

The storage periods for individual cookies are found in the details of the integrated application.

Withdrawal and removal options

As the user, you have complete control over the use of cookies. By changing the settings in the integrated application (Usercentrics), which is activated when you access our site, you can deactivate or restrict the transfer of cookies.

You can also deactivate or restrict the transfer of cookies by adjusting the settings in your Internet browser. You can thus delete any stored cookies at any time.

Many third-party applications that use cookies provide a feature for deactivation that stores a deactivation cookie. These opt-out cookies must not be deleted. Otherwise, the deactivation feature will no longer function. If you have deleted all cookies from your browser, you will need to reactivate the deactivation cookie the next time you visit our website.

If cookies are deactivated for our website, it is possible that some functions of the website will no longer be fully usable.
