Pursuant to Article 4 of the RGPD, the École Polytechnique is considered to be a “data controller” when one of its departments or a person, natural or legal, working legally on its behalf, determines the purposes of the data processing that is carried out via a website or page, and when the École Polytechnique defines the means by which this website can be made operational (e.g., hosting and structuring of the internet pages, deployment of “web” services, definition of the usage and connection data used).

ARTICLE 3. Information on the Processing Carried out in the Context on the Ecole Polytechnique Websites and Pages


The purpose of the websites and pages is to provide detailed information about all the activities of the École Polytechnique, its services and its partners. The websites and pages are also intended to allow users to ask questions about the activities and operation of the institution.


According to Article 6-e of the GDPR, “processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.” (for more information, refer to Article 2 paragraph 1).


The data processed within the framework of the École Polytechnique websites and pages may be : connection and usage data (“cookies”) ; contact data (e-mail, for example); location data (IP address and geographical area of connection – “cookies”) identity data (title, surname, first name, address, e-mail address, nationality, telephone number, educational institution, course of study, INE). For more information on the “cookies” processed by the École Polytechnique, please refer to article 4 of this Policy.


The main purpose of the websites is to disseminate information about the École Polytechnique, in particular: its news, its training offers, its organization (including the organization of schooling and administrative registration) and its operation. Several secondary purposes are also envisaged, in particular to display the names of competition winners and the lists of juries and any nominative information concerning admission to the School’s programs; to subscribe to the various newsletters offered by the school’s departments; to manage a communication space between users and the site via contact forms; to broadcast communication campaigns on events related to the School; to prevent and fight against computer fraud (spamming, hacking…) to optimize the layout and functioning of the sites according to their frequentation and their use noted. It is specified that in the online forms, the mandatory fields are marked with an asterisk. If you do not answer the mandatory questions, we will not be able to provide you with the requested service(s).


No personal data may be further processed in a manner incompatible with the purposes described above or under the collection forms. Your data is kept for the time necessary for the purpose of the processing when it comes to responding to your requests. Cookie data is processed for a maximum of 13 months, which can be extended with your prior and explicit consent (renewal of your authorization on the banners dedicated to the management of “cookies”).


Your personal data may be communicated to certain departments of the École Polytechnique in order to process your complaints and requests for information. On the Internet pages that allow it, we remind you that if you post a comment online, some of your personal data may be published on the website. Given the characteristics of the Internet network, which are the free capture of information disseminated and the difficulty, or even the impossibility, of controlling the use that could be made of it by third parties, we inform you that you may oppose such dissemination by sending your request to the contact address specified below:
