2.1. What is a cookie ?

The term “cookie” covers all traces deposited and read, for example, when consulting a website, reading an e-mail, installing or using software or a mobile application, regardless of the type of device used, such as a computer or smartphone. The purpose of a cookie is to collect information relating to the Internet user’s browsing and to send him/her services adapted to his/her device.

2.2. How long does a cookie last ?

With the exception of technical cookies, the recording of cookies on a User or Visitor’s terminal requires his consent. By continuing to use the Site after seeing the cookies banner displayed on the Site’s home page, the User or Visitor consents to the recording of cookies on his terminal. This consent is valid for a period of 13 months.

2.3. Quels cookies sont déposés sur le terminal de l’Utilisateur ou du Visiteur ?

The use of the Site leads to the installation, by NEXX360 or by third parties, of cookies on the User’s or Visitor’s terminal for various purposes as described below :

Technical cookies

These are cookies that are essential for browsing the Site (such as the User’s Member Account connection identifiers) which enable the User or Visitor to use the main functions of the Site and to secure his connection. For example, they allow the User to directly access reserved and personal areas of the Site, thanks to identifiers or data that he may have previously provided. If the User or Visitor decides to deactivate these cookies, his browsing experience may be limited and he may not be able to use all the Site’s functionalities.

Cookies for browsing analysis

These cookies record information relating to navigation on the Site in order to enable NEXX360 to know, for example, the number of pages displayed by the User or Visitor.

Sharing cookies (social networks)

The User or Visitor has the possibility to share content from the Site with others via various social networks, such as Facebook or Twitter. When the User or Visitor uses these share buttons (for example: “share” or “like”), a third party cookie is installed. If the User or Visitor is already connected to the social network when browsing the Site, the share buttons allow the User or Visitor to link the content consulted to his Member Account.

Advertising cookies

These are cookies used to present Users and Visitors with advertisements or to send information adapted to their centres of interest on our Site or outside our Site during their browsing on the Internet. In particular, they are used to limit the number of times the User or Visitor sees an advertisement and to help measure the effectiveness of an advertising campaign. NEXX360 informs the User and the Visitor that some third party companies may use their own advertising tool on the Site. These third party companies may use cookie and tagging technologies to collect information to measure the effectiveness of advertisements.

Please note that the issuance and use of cookies deposited by third parties are subject to the cookie policies of the persons depositing them. Only these third parties have the ability to access the information they contain.

2.4. How to disable cookies ?

Setting cookies on the Site

We offer Users and Visitors the possibility of accepting or refusing the cookies deposited via the Site by type of cookie, by the means set out below. You can at any time access your settings for managing cookies and other tracers by clicking here.

Please note that if you deactivate all cookies issued by our site, this action will neutralise the cookie deposited in order to record your consent or refusal. This therefore amounts to a reset of your parameters and implies that you have to express your choice in terms of Cookies again.

Browser settings

The User or Visitor may also deactivate all cookies by setting their Internet browser. However, the deactivation of cookies may prevent a User or Visitor from taking full advantage of the functionalities of our services. In particular, a User’s username and password will no longer be stored on the Site.

We would like to remind you that your choices regarding cookies depend on the browser and the device (computer, smartphone, tablet) you are using. In addition, deactivating the cookie will stop the display of ads targeted to your interests, but not other types of advertising. Deactivating cookies prevents the collection of information allowing better targeting of advertising but does not prevent the display of banners as such.
