Legal notice

Thank you for showing interest in our institute. Data protection is of high priority for the management of the ESRF. The use of the Internet pages of the ESRF is possible without any indication of personal data; however, if a data subject wants to use special services via our website, processing of personal data could become necessary. If the processing of personal data is necessary and there is no statutory basis for such processing, we generally obtain consent from the data subject.

By means of this data protection declaration, our institute would like to inform the general public of the nature, scope, and purpose of the personal data we collect, use and process via this website.

The ESRF endeavours this processing of personal data, such as the name, address, e-mail address, or telephone number of a data subject to be in line with the General Data Protection Regulation (GDPR), and in accordance with the country-specific data protection regulations applicable to the ESRF.

As the controller, the ESRF has implemented numerous technical and organizational measures to ensure the most complete protection of personal data processed through this website. However, Internet-based data transmissions may in principle have security gaps, so absolute protection may not be guaranteed. For this reason, every data subject is free to transfer personal data to us via alternative means, e.g. by telephone.


The data protection declaration of the ESRF is based on the terms used by the European legislator for the adoption of the General Data Protection Regulation (GDPR). Our data protection declaration should be legible and understandable for the general public, as well as our users, customers and business partners. To ensure this, we would like to first explain the terminology used.

In this data protection declaration, we use, inter alia, the following terms:

a) Personal data

Personal data means any information relating to an identified or identifiable natural person (“data subject”). An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.

b) Data subject

Data subject is any identified or identifiable natural person, whose personal data is processed by the controller responsible for the processing.

c) Processing

Processing is any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction.

d) Restriction of processing

Restriction of processing is the marking of stored personal data with the aim of limiting their processing in the future.

e) Profiling

Profiling means any form of automated processing of personal data consisting of the use of personal data to evaluate certain personal aspects relating to a natural person, in particular to analyse or predict aspects concerning that natural person’s performance at work, economic situation, health, personal preferences, interests, reliability, behaviour, location or movements.

f) Pseudonymisation

Pseudonymisation is the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organisational measures to ensure that the personal data are not attributed to an identified or identifiable natural person.

g) Controller or controller responsible for the processing

Controller or controller responsible for the processing is the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by Union or Member State law, the controller or the specific criteria for its nomination may be provided for by Union or Member State law.

h) Processor

Processor is a natural or legal person, public authority, agency or other body which processes personal data on behalf of the controller.

i) Recipient

Recipient is a natural or legal person, public authority, agency or another body, to which the personal data are disclosed, whether a third party or not. However, public authorities which may receive personal data in the framework of a particular inquiry in accordance with Union or Member State law shall not be regarded as recipients; the processing of those data by those public authorities shall be in compliance with the applicable data protection rules according to the purposes of the processing.

j) Third party

Third party is a natural or legal person, public authority, agency or body other than the data subject, controller, processor and persons who, under the direct authority of the controller or processor, are authorised to process personal data.

k) Consent

Consent of the data subject is any freely given, specific, informed and unambiguous indication of the data subject’s wishes by which he or she, by a statement or by a clear affirmative action, signifies agreement to the processing of personal data relating to him or her.

Cookies are text files that are stored in a computer system via an Internet browser.

Cookies do not personally identify users, although they do identify a user’s computer. Most browsers are initially set up to accept cookies. If you prefer, you can set your computer to refuse cookies by setting the parameters of your browser. Information on deleting or controlling cookies is available on the internet (e.g. or

Cookies are used on the site in a limited manner for site navigation purposes, to collect statistics about the behaviour of visitors to its websites or for access to third party services.

The data subject may, at any time, prevent the setting of cookies through our website by means of a corresponding setting of the Internet browser used, and may thus permanently deny the setting of cookies. Furthermore, already set cookies may be deleted at any time via an Internet browser or other software programs. This is possible in all popular Internet browsers. If the data subject deactivates the setting of cookies in the Internet browser used, not all functions of our website may be entirely usable.

Collection of general data and information

The website of the ESRF collects a series of general data and information when a data subject or automated system calls up the website. This general data and information are stored in the server log files. Collected may be (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) the sub-websites, (5) the date and time of access to the Internet site, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) any other similar data and information that may be used in the event of attacks on our information technology systems.

When using these general data and information, the ESRF does not draw any conclusions about the data subject. Rather, this information is needed to (1) deliver the content of our website correctly, (2) optimize the content of our website as well as its advertisement, (3) ensure the long-term viability of our information technology systems and website technology, and (4) provide law enforcement authorities with the information necessary for criminal prosecution in case of a cyber-attack. Therefore, the ESRF analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of our institute, and to ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.

Subscription to our newsletters

On the website of the ESRF, users are given the opportunity to subscribe to a number of our institute’s newsletters. The input masks used for this purpose determines what personal data are transmitted.

The ESRF informs its users, visitors and business partners regularly by means of newsletters about news and events. The institute’s newsletters may only be received by the data subject if (1) the data subject has a valid e-mail address and (2) the data subject registers for the newsletter shipping. A confirmation e-mail will be sent to the e-mail address registered by a data subject for the first time for newsletter shipping, for legal reasons, in the double opt-in procedure. This confirmation e-mail is used to prove whether the owner of the e-mail address as the data subject is authorized to receive the newsletter.

The personal data collected as part of a registration for the newsletters will only be used to send our newsletters. In addition, subscribers to the newsletters may be informed by e-mail, as long as this is necessary for the operation of the newsletter service or a registration in question, as this could be the case in the event of modifications to the newsletter offer, or in the event of a change in technical circumstances. There will be no transfer of personal data collected by the newsletter service to third parties. The subscription to our newsletters may be terminated by the data subject at any time. The consent to the storage of personal data, which the data subject has given for shipping the newsletter, may be revoked at any time by unsubscribing from the newsletter directly on the website of the controller (see or by communicating this to the controller in a different way (email).

Contact possibility via the website

The website of the ESRF contains information that enables a quick electronic contact to our institute, as well as direct communication with us, which also includes a general e-mail address. If a data subject contacts the controller by e-mail or via a contact form, the personal data transmitted by the data subject are automatically stored. Such personal data transmitted on a voluntary basis by a data subject to the data controller are stored for the purpose of processing or contacting the data subject. There is no transfer of this personal data to third parties.

Data protection provisions about the application and use of Matomo

On this website, the controller has integrated the Matomo component. Matomo is an open-source software tool for web analysis. Web analysis is the collection, gathering and evaluation of data on the behavior of visitors from Internet sites. A web analysis tool collects, inter alia, data on the website from which a data subject came to a website (so-called referrer), which pages of the website were accessed or how often and for which period of time a sub-page was viewed. A web analysis is mainly used for the optimization of a website and the cost-benefit analysis of Internet advertising.

The software is operated on the server of the controller, the data protection-sensitive log files are stored exclusively on this server.

The purpose of the Matomo component is the analysis of the visitor flows on our website. The controller uses the obtained data and information, inter alia, to evaluate the use of this website in order to compile online reports, which show the activities on our Internet pages.

Matomo sets a cookie on the information technology system of the data subject. The definition of cookies is explained above. With the setting of the cookie, an analysis of the use of our website is enabled. With each call-up to one of the individual pages of this website, via  Matomo component, the Internet browser on the information technology system of the data subject is automatically prompted to submit data for the purpose of online analysis to our server. During the course of this technical procedure, the following information is stored:

  • the anonymised ip address of the visitor, i.e with the last 2 bytes masked (e.g.
  • the visitor’s operating system (for example Windows, Mac, etc.),
  • the date and time of the visit to the site,
  • the pages accessed,
  • if the visitor follows a link to get to the page, the address (URL) of the page containing the link,
  • the type of browser used.

These personal data are stored by us. We do not forward this personal data to third parties.

The data subject may, as stated above, prevent the setting of cookies through our website at any time by means of a corresponding adjustment of the web browser used and thus permanently deny the setting of cookies. Such an adjustment to the used Internet browser would also prevent Matomo from setting a cookie on the information technology system of the data subject. In addition, cookies already in use by Matomo may be deleted at any time via a web browser or other software programs.

In addition, the data subject has the possibility of objecting to a collection of data relating to a use of this Internet site that are generated by Matomo as well as the processing of these data by Matomo and the chance to preclude any such. For this, the data subject must set a “Do Not Track” option in the browser.

When users have set their web browser to “I do not want to be tracked” (DoNotTrack is enabled) then Matomo will not track these visits.  Do Not Track is a technology and policy proposal that enables users to opt out of tracking by websites they do not visit, including analytics services, advertising networks, and social platforms.
