eupinions is an independent platform for European public opinion. We collect, analyse and comment on what the European public thinks about current political issues and megatrends.

eupinions employs cutting-edge data collection techniques. Every quarter, we collect samples from each EU member state in 22 languages. Our data meets the highest scientific standards and is representative with regard to age, gender, education and country/region.

eupinions is a project of Bertelsmann Stiftung. The data is collected by Latana (formerly known as Dalia Research).

Isabell Hoffmann

Founder and Co-author

Isabell founded eupinions in 2015 as a project of Bertelsmann Stiftung in cooperation with Catherine E. De Vries of Bocconi University and Nico Jaspers of Dalia Research (now Latana). As an expert researcher on democracy and legitimacy in the European Union, she has managed research projects on the role of national parliaments in the EU as well as the origins and impact of populism, nationalism and authoritarianism in Europe. Isabell studied political science and economics at the Institut d’études politiques de Paris (Sciences Po). Before joining Bertelsmann Stiftung in 2008, she worked as a political editor for the German weekly newspaper Die Zeit.

Scientific adviser and Co-author

Catherine is Professor of Politics at Bocconi University in Milan. She has a strong commitment to and interest in unravelling some of the most important societal and political problems facing Europe today, such as Euroscepticism and the EU’s future, the rise of parties challenging the political mainstream and the electoral and political consequences of corruption and malfeasance. She has published extensively in academic journals and the popular press. Over the years, she has received widespread recognition for her work, such as the Emerging Scholar Award for contribution to the field of elections, public opinion and voting behaviour from the American Political Science Association in 2014 and election as a Young Global Leader of the World Economic Forum in 2013.

Latana is a cutting-edge insights platform that helps organisations to gather the information they need to make better decisions. Latana enables accurate measurement and tracking of how people perceive products, ideas, and events. Their vision is to lead the way in a new generation of research technologies to help organisations better understand the needs, opinions, and preferences of people around the world.

Europe is going through a hectic period of challenge and change. Economic and fiscal crises, threats to internal security, tectonic geo-political shifts along with Brexit and the questioning of Western values within the European Union are all exerting pressure on mainstream politics. Once more, the future of democracy and the unity of Europe seem fraught with uncertainty.

This entire background forces Europeans to engage in a fundamental debate about their future: What are the great questions about the future that Europeans should tackle together? Or not? Within which framework should they act? Collectively or individually? Is efficiency more important than unity? Does the pragmatic search for solutions breach European principles?

eupinions is gathering the opinions of Europeans on these central questions about the future of Europe and bringing them to bear in the public debate. We would like to give Europeans a representative voice in this discussion.

You can find our contact details in the imprint of the online offering, while the contacts for questions concerning processing of the personal data are named directly in this Privacy Statement.

We, the Bertelsmann Stiftung, are strongly committed to protecting your privacy and your private and personal data. We collect, save, and use your personal data strictly in accordance with the provisions of this Privacy Statement and the applicable data protection provisions, including without limitation the European General Data Protection Regulation (GDPR) and national data protection provisions. 
With this Privacy Statement, we wish to inform you to what extent and for what purpose your personal data is processed in connection with the use of our online offering.

Personal data
Personal data is all information about an identified or identifiable individual. This includes information about your identity such as your name, your e-mail address, or your postal address. Any information that cannot be directly linked to your identity (e.g. statistical details such as the number of users of the online offering) is, however, not considered to be personal data.

You can essentially use our online offering without disclosing your identity and without providing any personal data. In that case, we will merely collect general information about your visit to our online offering. However, some of the services offered require you to provide certain personal data. As a rule, we will process such data only for purposes connected with the use of this online offering, including without limitation for the provision of the desired information. Whenever personal data is collected, you are only required to provide the data that is absolutely essential. Also, you may be asked to provide additional details, which are optional information provided voluntarily. We let you know in each case whether the input fields are for mandatory or optional details. More specific details are provided in the relevant section of this Privacy Statement.

There is no automated decision-making on the basis of your personal data in connection with the use of our online offering.

Processing personal data
We store the information provided by you on protected dedicated servers located within the European Union. Technical and organisational measures are taken to protect such servers against loss, destruction, access, modification, or dissemination of your data by unauthorized persons. Access to your data will be permitted only to a limited number of persons in charge of the technical, commercial, or editorial support of the servers. Notwithstanding regular controls, full protection against all risks cannot be provided.

Your personal data is transmitted over the Internet in encrypted form. We use SSL (Secure Socket Layer) encryption for transmission of data.

Disclosure of personal data to third parties
We use your personal information exclusively for providing the provide services that you have requested from us. Insofar as we use external service providers in performing the service requested, such external service providers will also access the data exclusively for the purpose of performing the service. By taking the necessary technical and organisational measures we ensure compliance with privacy policies and we demand the same of our external partners.

Moreover, we will not disclose the data to any third parties, including without limitation for advertising purposes, without your express consent. We will disclose your personal data only if you have given your consent to disclosure of the data or insofar as we are entitled or obligated to do so under legal provisions and/or administrative or judicial orders. This may include, without being limited to, giving information for purposes of criminal prosecution, in order to avert danger, or in order to enforce intellectual property rights.

Legal basis of data processing
Insofar as we obtain your consent to processing your personal data, Article 6(1)(a) of the GDPR constitutes the legal basis for such data processing.

Insofar as we process your personal data because processing is necessary for the performance of a contract or is necessary under a quasi-contractual relationship with you, the lawfulness of data processing is based on Article 6(1)(b) of the GDPR.

Insofar as we process your personal data because processing is necessary for compliance with a legal obligation, the lawfulness of data processing is based on Article 6(1)(c) of the GDPR.

Furthermore, Article 6(1)(f) of the GDPR may constitute the legal basis for data processing, if processing of your personal data is necessary for the purposes of the legitimate interests pursued by our Foundation or by a third party, except where such interests are overridden by your interests or your fundamental rights and freedoms which require protection of personal data.

Throughout this Privacy Statement, we always point to the legal basis underlying our processing of your personal data.

Deletion of data and duration of storage
We invariably delete or block any personal data provided by you as soon as the purpose of storage of such data ceases to apply. However, we may continue to store your personal data beyond that, if such storage is governed by legal provisions to which we are subject, including without limitation the legal obligation to retain business records and documentation. In such a case, we will delete or block the personal data after the prescribed period of time has expired.

Use of our online offering

Use of cookies
Like many other websites, our online offering uses cookies. Cookies are small text files that are stored on your computer and store certain settings and data of your web browser for the exchange with our online offering. As a rule, a cookie contains the name of the domain from which the cookie file has been sent as well as information about the age of the cookie and an alphanumeric identifier.

Cookies enable us recognise your computer and make any default settings immediately available. Cookies help us to improve our online offering and to provide you with an even better service customised to meet your particular requirements. This also constitutes a legitimate interest in the processing of the data in accordance with Article 6(1)(f) of the GDPR.

The cookies we use are so-called session cookies that are automatically deleted after the end of the browser session. In individual cases, we may use cookies with a longer storage time so that your default settings and preferences may be considered when you visit our online offering the next time.

Most web browsers are set to accept cookies by default. However, you can disable the storage of cookies or set up your web browser to inform you when you receive a cookie. It is also possible to manually delete stored cookies in the browser settings. Please note that your use of our online offering may be limited or restricted if you refuse to save cookies or delete necessary cookies.

Analysis cookies
Our online offering uses cookies which, based on the technologies of etracker GmbH, allow the analysis of your user behaviour, so-called analysis cookies. We use these cookies to collect and save the following data:

  • Frequency of page views
  • Search terms used
  • Use of website functions
  • Shortened IP address
  • Date and time of the query
  • Access status/HTTP status code
  • Respective data quantity transferred
  •  Website from which the request comes
  • Browser
  • Operating system and its interface
  • Language and version of the browser software

When storing website visitor data, certain data, including without limitation visitors' IP addresses, device and domain data, is stored in shortened and/or encrypted form so that the individual user cannot be identified based on the data. The data collected is never merged with other existing data, e.g. for the purpose of identifying an individual.

The IP address is shortened as soon as possible on an automated basis without you as a user having to carry out any special adjustments or configurations.

We use analysis cookies in order to improve the quality of our online offering and its contents and in order to examine and optimise the reach and searchability of our online offering. These purposes at the same time constitute a legitimate interest within the meaning of the legal basis for data processing in accordance with Article 6(1)(f) of the GDPR.


You can register for the use of our online offering. To register, you have to provide the data requested during registration, such as your name, address and e-mail address. In addition, we record the date and time of registration. During the registration process, we ask for your consent to using your data. That gives you the advantage of not having to enter this data every time you wish to use our online service or to place an order.

If you give your consent, processing of data provided for registration purposes is based on Article 6(1) (a) of the GDPR. If you register with us for the purposes of performance or initiation of a contract, the legal basis for processing of the data is additionally constituted by Article 6(1)(b) of the GDPR.

Upon registration, an account is created for you. The data in the account is stored as long as there is an active contact. If there has been no activity for a period of three years, the status of the contact is set to Inactive. You can at any time demand deletion of your account.


Communication with us

There are various ways of contacting us, including but not limited to the contact form on our website. In addition, we will be happy to inform you regularly by e-mailing you our newsletters which deal with various topics.

Contact form
If you wish to use the contact form of our online offering, we will collect the personal data that you provide in the contact form, including but not limited to your name and e-mail address. In addition, we record the date and time of your enquiry. We process any data transmitted through the contact form exclusively for the purpose of answering your enquiry or reacting to your concern.

It is up to you to decide what information you provide in the contact form. In accordance with Article 6(1)(a) of the GDPR, your consent constitutes the legal basis for processing your data.

After the matter has been dealt with, the data is stored for some time in case you have any further questions. Without prejudice to the relevant legal retention periods, you may request deletion of the data at any time, otherwise the data will be deleted once the matter has been conclusively dealt with.

If you subscribe to our newsletter, we will use your e-mail address for information purposes of Bertelsmann Foundation until you unsubscribe from the newsletter. You will be regularly updated by e-mail on current topics related to our projects and receive e-mails informing you of special occasions such as new studies and events. Such e-mails may be personalised and individualised on the basis of information we have about you.

Unless you have given us your consent in writing, we use the so-called double opt-in procedure for subscription to our newsletter, i.e. we will send you our newsletter by e-mail only once you have expressly confirmed that you want us to activate transmission of the newsletter. We will then send you a notification e-mail and ask you to confirm, by clicking on one of the links contained in that e-mail, that you wish to receive our newsletter.

If you have explicitly subscribed to our newsletter, your consent constitutes the legal basis for processing of your data in accordance with Article 6(1)(a) of the GDPR. Under the applicable legal provisions, we may send you our newsletter without having obtained your express consent based on the fact that you have ordered certain publications from us and we have therefore received your e-mail address and you have not objected to receiving information from us by e-mail. In this case, our legitimate interest in direct mailing constitutes the legal basis in accordance with Article 6(1)(f) of the GDPR.

If you do no longer wish to receive our newsletters, you can revoke your consent at any time with effect for the future and/or object to receiving the newsletter without incurring any costs other than the transmission costs in accordance with the basic tariffs. Simply use this unsubscribe link contained in every newsletter or send a message to us or our data controller.

You can comment our articles in our online offering. To do so, you have to give you name; you can also use an alias. In addition, you are required to let us know your e-mail address. We need your e-mail address to contact you in the event of any complaints about your posts and in order to ask you to comment on such complaints; in addition, we will store the IP address. You cannot post any comments unless you have provided those details. However, only the name or the alias selected by you will be shown together with the comment upon publication. In accordance with Article 6(1)(a) of the GDPR, your consent constitutes the legal basis for processing your data.

Social Media
Our online offering contains links or plugins to the social networks Facebook, LinkedIn, Soundcloud, Twitter, Xing, YouTube. The links are identified by the logo of their relevant providers.

Clicking on a link opens the relevant social media web pages; this Privacy Statement does not apply to such web pages. For further details on the provisions applicable on such web pages please refer to the relevant privacy statements of each of the providers; you can find them at:

Facebook: http://www.facebook.com/policy.php

Xing: https://www.xing.com/privacy

Youtube: https://www.google.com/policies/privacy/?hl=en

No personal information is forwarded to the relevant providers before clicking on the links or calling up a plugin. Calling up the linked website also constitutes the basis for data processing by the relevant website provider.

Use of YouTube
Our online offering contains videos for which we use plugins from the Google-run site YouTube ("YouTube"). The operator of the service is YouTube LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. If you call up an internet page of our online offering which contains a video, a connection with the YouTube servers is created. On that occasion, the YouTube server is told which internet pages of our online offering you have visited.

If you are logged in to your YouTube account at that time, you allow YouTube to directly associate your browsing behaviour with your personal profile. You can prevent that by logging out of your YouTube account first. For further information on the handling of user data please refer to the Google privacy statement at https://www.google.de/intl/de/policies/privacy/ which also applies to YouTube.

Using YouTube enables us to show you videos and give you more information on ourselves and our projects; this at the same time constitutes our legitimate interest within the meaning of Article 6(1)(f) of the GDPR.
