Data processing

The following programs and service providers are used for data processing:

Server data

The provider of this website collects a series of general data and information when a data subject or automated system pulls up the website. This general data and information are stored in the server log files. The following may be collected:

  1. the browser types and versions used
  2. the operating system used by the accessing system
  3. the website from which an accessing system reaches our website (so-called referrers)
  4. host name of the accessing system
  5. the date and time of access to the Internet site
  6. an Internet protocol address (IP address)

This general data and information are not amalgamated with other data sources.

Legal basis for the data processing is provided in Article 6(1) lit. b GDPR that allows the processing of data for the fulfillment of a contract or for precontractual measures.


We don’t use analytics, advertising or social media cookies. We are using cookies, however, which enable us to provide you with improved services. For that reason, we use the website cookie “pll_language”, which saves the last selected language for the website for one year.

Content management

We use the system “WordPress” in order to manage the content of our website. Plug-ins transferring data to third party providers are not used. Embedded content by third party providers is not used.

Contents of third party providers

Embedded content by third party providers is not used.

Survey System

For operating the Global Survey we use the survey software Qualtrics. Qualtrics creates the most advanced online survey software for corporations, research companies, and universities.
Please visit the Qualtrics Privacy Statement for further information.

Qualtrics surveys run in compliance with the European legislation.
Please visit the Qualtrics GDPR statement for further Information.

The software is provided in an Application Service Provider (ASP) model, accessed using a modern browser via the Internet. All of Qualtrics products are self-service, whereby the end-users are solely responsible for what data to collect and from whom. All customer data collected using the software are stored in a single secure data center in North America (United States, California).

We designed our survey so that it will not collect any personal data or other identifying information such as geo-location or IP address. We enabled anonymized responses in our survey so that no location or IP information are collected.
In addition, when distributing our survey we are using anonymous links, no contact personal data will be associated with the resulting response. Using both of the above options means that the completed responses will be completely anonymous with no embedded identifying information.
