Policy regarding cookies and similar technologies

To make the use of our website and application easier and more enjoyable we use cookies (by cookies we mean the collection of cookies, trackers, pixels, plug-ins, beacons, recaptchas, apps and applets). Cookies enable our website to remember your actions and preferences (user name, language, font size and other display parameters) for a fixed period of time, so you do not have to enter this data every time you consult the website or surf from one page to another.

1. What is a cookie?

A cookie is a small text file, possibly encrypted, that a website stores on your computer or other technological devices (smartphone, tablet, etc.) that you use to consult the website. These cookies are designed to both speed up and personalise your use of the website every time you visit and  return to it.

To this end, cookies exchange data between your web browser (Chrome, Firefox, Internet Explorer, Safari, etc.) and the server hosting the website. For instance, cookies provide information about your preferences for the display of the website (language, font size...), your browsing history, your choices regarding the options offered by a website and the registration data.

Cookies enable us, for example, to compare new users with old, gain insight into how people navigate the website, count website visitors and obtain data that will enable us to improve the future surfing experience.

Cookies do not keep trace of a user's personal data, and identifiable information is never registered. If you do not wish cookies to be used, you must configure your computer’s parameters to erase all cookies from websites and/or receive a notification if cookies are stored.

If you do not wish to change the cookies setting, you can simply continue your visit to the website.

2.1 Cookies that are strictly necessary for surfing

These cookies are essential to browse our website and use its functionalities. They cannot be disabled in our systems. They are placed on your terminal in response to what you are doing and that constitutes a service request, such as determining your privacy preferences, logging in (accessing secure areas of the website) or filling forms.

They make it possible to:

  • browse between different sections of websites;
  • fill in forms;
  • securely verify your identity before granting access to your personal data when a personal account has been created, including browsing between the secure areas of the website requiring authentication.

You can configure your internet browser to block cookies or to warn you about the existence of cookies. Should you later refuse those cookies, certain sections of the website or certain services will either not work properly or not work at all.

2.2 Functional cookies

Functional cookies, also known as ‘functionality cookies’, provide enhanced functionality and personalisation. They facilitate and analyse the operation of the website to make its use more pleasant and personalised by enabling the site to remember the choices you have made and providing you with more precise and personal characteristics.

More specifically, they make it possible to:

  • personalise services by remembering your preferences (your user name, language choice, currency, region where you are located, etc);
  • avoid having to reformulate your choices each time you visit the website (changes made by the user are retained, such as text size or font);
  • collect data communicated on online forms;
  • provide services that you have requested (like watching a video or leaving a comment on a blog);
  • compile statistics (e.g. the number of unique visitors);
  • analyse the use of the website and the popularity of our pages.

These cookies are specific to the content management platform (WordPress, Drupal, Liferay, Craft CMS): a kind of software that can be described as the ‘engine’ of a website.

The data these cookies collect is anonymised and not capable of tracking your surfing behaviour on other websites. These cookies also expire when you close your browser, with the exception of the cookie that specifies your language preference. They are, therefore, removed from your computer or other digital devices once you close this software.

If you block these cookies, all or part of our services may not function properly.

2.3 Analytical cookies and performance cookies

These cookies collect information about how visitors use our website and, in particular, the frequency with which the website is visited and the users' behaviour while on it.

More specifically, these cookies enable us to compile statistics, for example, by counting the visits and determining the origin of the visitors so we can measure and improve the performance of our website and our services. These cookies help determine which pages are the most and the least popular and to see how visitors surf the website and use the services.

These cookies also monitor performance  by signalling whether error messages are generated, how often this happens and in response to which actions.

The cookies do not collect information that can be used to identify visitors. Since the data collected by these cookies has already been aggregated, information remains anonymous. These cookies are, therefore, only intended to improve the functioning of the website.

The data collected by the cookies is aggregated. Consequently, if you disable them, we will not know when you visited our website or used the services and will not be able to monitor performance.

2.4 Targeted cookies

These cookies collect data relating to your browsing habits on the internet and your use of our services to provide you with advertising that is customised to your specific interests. They can also allow you to limit the number of times that you see an advertising message and help us evaluate the effectiveness of our advertising campaigns. Usually, they are installed by advertising networks with the permission of the website operator. These cookies remember visits to a website and share that information with other companies (e.g. advertising companies). These targeted cookies are often linked to the functionalities of the website provided by the partner company.

They make it possible to:

  • prevent you from being repeatedly confronted with the same advertising messages;
  • measure the effectiveness of our various communication actions or an advertising campaign;
  • personalise the advertising on our websites and other communication platforms.

The data is collected and shared with third parties to target certain types of audiences and propose optimising solutions to our administrations, publishers and possibly advertisers. No personal data is collected and an individual cannot be identified through the data that is collected.

Targeted cookies are based on the unique identification number of your browser and digital device on the internet (IP address). If you block these cookies you will continue to see advertisements. You will receive less targeted advertising.

2.5 Cookies issued by third parties on our websites

Cookies originating from third parties may be installed in applications (from third parties) built into our website or services and in advertisements (illustrations, animations, videos, etc.) disseminated via advertising space that is built into our website or services. This is particularly the case with buttons, such as ‘Share’, and ‘Like’, originating from social networks such as Facebook, Twitter, LinkedIn and Viadeo.

The social network that provides such an application button will be able to identify you thanks to that button, even if you have not used it while consulting our website or our services. This type of application button may enable the concerned social network to follow your surfing on our website or services when your account with that social network is enabled (session is not closed) on your device while surfing our website or services.

The issuing and use of cookies by third parties are subject to the privacy protection policies of those third parties. We do not have any control over the process used by social networks to collect data about your surfing behaviour on their websites or services and their linking of it to the personal data they have.

We suggest you consult the privacy protection policy of those social networks to find out about the uses’ purposes — notably for advertising — of the surfing data that they can collect thanks to those application buttons. In particular, these protection policies must enable you to exercise your choices concerning these social networks by defining the parameters of your user accounts for each of these networks.

We remind you that you can choose at any time, simply and free of charge, to refuse the registration of cookies on your digital device, so that neither we nor our partners have access to the data collected by the cookies.

3. How do I manage the cookies on my computer, tablet, etc?

Most web browsers are automatically configured to accept cookies. However, you can configure your browser to accept or block all cookies or just some of them.

You can delete cookies already installed on your device (computer, smartphone, tablet...) at any time and configure most browsers to block cookies. However, in that instance, you may have to specify certain preferences each time that you visit our website. There is also a risk of certain services and functionalities being inaccessible. In other words, we cannot guarantee you access to all the services on our websites if you refuse to register cookies.
