11.2 Cookies

When using the APPLICATION, information relating to the customer’s navigation may be recorded in files installed on their device (Cookies). Cookies can in particular allow for the compiling of statistics relating to the APPLICATION in terms of usage, visits, recording of information submitted through forms, etc. The CUSTOMER can configure their device in such a way so as to deactivate cookies.

11.3 Social networks

The APPLICATION uses and/or is likely to use plug-ins from the Facebook social network, and other social networks (Twitter, Instagram, etc.).

In this context, when the USER uses the APPLICATION likely to contain a plug-in, their browser establishes a connection with the servers of the social network concerned. Should the USER be connected to Facebook or another social network during their use, the social network concerned may directly link their visit to their user account.

The buttons and spaces displaying the network’s content may appear on the APPLICATION to create a more “social” experience. The content of these social modules come directly from the networks. When a Customer clicks on “Like”, “Fan” or forwards a comment by means of a social module, their activity is published on the network concerned and shown to their connections, who can see the module on the same site. The items you like can also appear on your profile (you can control this parameter in the basic information section). The APPLICATION may also contain buttons allowing the Customer to become a “Fan” of the Company’s Facebook or Instagram pages. All of this information will be sent to and registered on the server of the social network concerned.

The Company shall not be held responsible in terms of any use on the part of the Facebook Company, other social networks, or third parties that could arise from the “Like”, “Fan” and “Comment” buttons or their equivalents, in their current or future states.

Should the USER not want these social networks to form any links to the information collected via the APPLICATION, they may need to log out of their account prior to using the APPLICATION.

The Company undertakes only to communicate this information on the demand of a duly authorised legal or administrative authority, or an entity associated with the State in which they are processed and/or stored.

The Company may also use the IP address to identify Customers who may have breached the provisions of these Terms and Conditions or may have harmed the Company. In this case, the Company shall have good reason to hand over connection data to the relevant authorities.

The Company shall also store all of the data collected in accordance with the legal and regulatory provisions in force in France.

11.5 The Data Protection Act

The processing of this Personal Data is subject to a declaration made with the French National Data Protection Authority (CNIL), number 1901610 v 0.

In accordance with Act 78-17 of 6 January 1978, amended, the CUSTOMER has the right to view, modify or delete any personal information that may have been collected by the Company.

These rights may be exercised by initiating contact through the following address:


Should one or more of the provisions of these Terms and Conditions be deemed to be null, unenforceable, or declared as such in application of a particular law, regulation or following a definitive decision handed down by the competent authority, the remaining provisions shall not be affected, except if the nullity affects a provision that is crucial in the light of these Terms and Conditions.

In this case, the Parties shall agree to replace the null or unenforceable provisions with new valid provisions, aligned with the spirit of these Terms and Conditions.


These Terms and Conditions of Sale and Use are governed by French law.

In the event of a dispute, the court with jurisdiction shall be the court in the location of the registered domicile of the appellant or, at the request of the appellant, the effective location of delivery of the product.

The instance of the Company not invoking a particular right or prerogative provided for by these Terms and Conditions may not in any way be deemed to be a waiving or impediment to exercising any right or prerogative conferred by these Terms and Conditions, the applicable laws or regulations.

Prior to any litigation, the Parties shall seek an amicable solution to any dispute that may have arisen between them, in particular regarding the interpretation and/or execution and/or termination of the provisions of these Terms and Conditions. The CUSTOMER or User is informed that any voluntary process shall not interrupt any deadline for appeal (guarantee periods, limitation periods).
