Privacy policy

The object of this Privacy Policy (hereinafter the "Policy") is to inform the users and members (hereinafter collectively the "User") of the website (hereinafter the "Website") of the resources implemented to:

  • Collect and process the personal data of the User, in accordance with the French Data Protection Act no. 78-17 of 6 January 1978, as amended by the Law of 20 June 2018 and the Ordinance n° 2018-1125 of December 18, 2018, relating to personal data protection, and Regulation no. 2016-679 of 27 April 2016 on the protection of individuals with regard to the processing of personal data and the free circulation of such data (hereinafter the "Regulations");
  • View, process and store information relating to the User's browsing of the Website, which may be recorded using “Cookies” (hereinafter "Cookies").

The data controller of the personal data is SUEZ, a limited company (société anonyme) registered with the Nanterre Trade and Companies Register under number 433 466 570, having its head office at Tour CB 21, 16, place de l’Iris, 92040 Paris La Défense, France (hereinafter the "Publisher").

The Publisher may amend the Policy at any time, in particular in order to comply with any regulatory, case law, editorial or technical developments. Before browsing the Website, the User must read the latest version of the Policy.

This Privacy Policy forms an integral part of the General Terms of Use of the Website.

I. Personal data protection

While the User is using the Website, the Publisher may collect and process personal data so that the User can access the services offered by the Website (hereinafter the "Services"). For each form, the Publisher undertakes to limit the collection of data to what is strictly necessary (data minimisation principle).


1) Which data is collected?

  • Contact Data: this is the mandatory data that the User enters when creating an account on the Website and/or filling in the contact form and/or reporting an abusive comment via the dedicated form, namely: surname, first name, email address.
  • Data voluntarily disclosed by the User: refers to the personal information that the User voluntarily discloses to the Publisher by filling in the free text fields provided (i) in the contact form, namely "Your request" and/or (ii) in his profile sheet, namely “Title”, "Position", "Organization", "City", "Country" and "Summary", or by uploading a profile photo to his account and/or (iii) in the abusive comment form, e.g., "Why are you reporting this comment? " or in the "Comments" fields associated with the various content on the Website. The Publisher does not require personal data to be entered in these free text fields and strongly advises the User to avoid disclosing personal data that he does not wish to make public, or any personal data of third parties without having obtained the prior and detailed consent of said third party (also authorising the Publisher to publish said third party personal data via the Website). In particular, the User is free to decide whether to upload a photo to his profile, and if he does so, he accepts that his photo will then be visible to all Users of the Website (regardless of whether they are members of the Website), except where he has chosen the option "anonymous profile" in the account settings options. In any event, SUEZ shall endeavour to use only data that is strictly necessary for using the services on the Website or for processing the User's request (hereinafter "Published Data"). If the User decides to voluntarily disclose specific data about him (such as his ethnic origin, political opinions, religious or philosophical beliefs, membership of a trade union, physical or mental health, sexual orientation or criminal record) he acknowledges that he has chosen to publish such data on his profile and that it will be visible to other users. The User acknowledges and accepts that he should only publish personal data on his profile that he agrees to make public.
  • Browsing data: data that the Publisher collects while the User is browsing the Website such as the date, logging on and/or browsing time, type of browser, browser language and his IP address.

All this data will be referred to collectively hereinafter as the "Data".

The data collected in connection with the use of the Website is processed with the following objectives:

  • Management of the community: managing User registrations and profiles when setting up their accounts; managing User contributions and comments;
  • Customisation of the platform's home page to match the User's interests;
  • Managing User participation in Challenges;
  • Handling questions and requests sent by Users via forms;
  • Dealing with inappropriate or illicit comments reported via forms;
  • Compiling statistics and measurements on the use of the Services (via Cookies)


When collecting the Data, the User is informed if certain Data must be necessarily filled in or if they are optional. Data identified with an asterisk in the contact form is mandatory. In the absence of information of mandatory sections, access to the Services and their use by the User may be restricted.

The use of Contact data and Data published voluntarily by the User is therefore necessary for the performance of the contract concluded between the User and the Publisher.

The User consents to enter into the contract by filling in the account registration form, by sending his request for information or his report using the contact and abusive comment forms provided for this purpose, and by providing his contact details. The Publisher performs the contract by granting access to the collaborative features and/or responding to the User's request by sending him the information by email. This performance of the contract entails knowing the identity of the User and being able to interact with him. The Publisher may also process certain Data where there is a legitimate interest (in particular to guarantee the Website's security) or with the express consent of the User (if the Publisher expressly mentions it on the form).


3) Recipients of the Data collected

When a User creates an account and becomes a member of the Website, the Data that he has entered on his profile is made visible to all Users of the Website (regardless of whether they are members of the Website).
