On the EUROCHAMP data centre we collect some information in order to generate audience measurements. We do not sell any of these information.

All the personal data stored are archived by the CNRS (in France), and cookies are stored on your web browser no longer than 13 months.

Please note that we collect two different types of statistics : one for all the website, and one for the data and metadata usage. We use a specific tool for each one. If you wish not to be tracked, you will find a form to do so at the end of each section.

General statistics with Matomo

Why

In order to measure the general use of the data centre, we use the open source web analytics Matomo. This tool brings us for instance the number of visitors on the website.

What we collect and use

  • Cookies: to identify your computer as a unique visitor
  • Usage data: data like your anonymized IP address, the date and duration of your visit, information from your device (device type, operating system, screen resolution, language and web browser type)

Data and metadata usage statistics

Why

In order to help partners in the identification of the data that generate the most interest by the scientific community, but also to better identify the type of users and the visibility of the data centre around the world, statistics data usage are done. For that purpose, for each metadata, we track the number of read and the number of data download.

This part only affects the pages Atmospheric simulation chamber studies, IR spectra and Mass spectra.

What we collect and use

  • Cookies:
    • to identify your computer as a unique visitor if you are not logged in
    • to store the country you provided with the form the first time you go to one of the catalogue
  • Usage data:
    • your orcid if you are logged in to identify you as a unique visitor and know if you are a partner or not
    • for each metadata, the last time you have seen it and the last time you have downloaded its data

Opt-out

The personal information we use allow us to be more accurate to record statistics. If you choose to be anonymous, when you read a metadata or download a data, we will increment the number of read or download without use any of your personal data (without your id, your country and the last time you have seen or download the metadata or the data).
