  • the mandatory or optional nature of the data
  • the recipient(s) of the data collected
  • the retention period of the collected data
  • your IT and Liberties rights and how to exercise them

On each form on the website, one or more check box(es) allows you to explicitly give your consent for the collection and processing of the personal data requested. This allows RECTOR LESAGE SAS to ensure that the personal data transmitted to it can actually be used for the purpose(s) explicitly announced on the form and accepted by the Internet user. Each box checked corresponds to a particular purpose of processing personal data and will serve as legal proof of the Internet user’s consent.

Under no circumstances will RECTOR LESAGE SAS be able to use this personal data for a purpose other than that(s) explicitly announced on the form and accepted by the Internet user. Likewise, this personal data cannot be transmitted or assigned to third parties without explicit mention of this possibility on the form.

The site uses cookies. These are small files downloaded to your computer that help the site run smoothly and securely (session and security cookies) and that record information about how our visitors view our site (tracking cookies). This allows us, for example, to know which pages are most viewed by our visitors and how much time they spend on our site.

By configuring your browser, you can disable cookies or be alerted when cookies are about to be downloaded to your computer. However, disabling all cookies may prevent you from properly using all the features of this site.

Google Analytics

This site uses the Google Analytics web analysis service. This allows us to analyze how Internet users use our site in order to offer them a better browsing experience. To do this, Google Analytics uses tracking cookies to follow an Internet user’s journey on the site. These cookies are kept for a period of 13 months.

We have activated IP anonymization for this site. This means that the IP addresses collected by Google Analytics are systematically shortened to make it impossible to identify Internet users. In exceptional cases, the full IP address may be transferred to a Google server in the United States and immediately shortened there. Google uses the information collected via cookies on behalf of RECTOR LESAGE SAS, for the purpose of analyzing the browsing habits of Internet users and providing reports on site activity.

Google provides users with a plug-in for their browser allowing them to prevent the collection of data relating to their browsing on websites using Google Analytics.

This plug-in is available at this address:

Google Remarketing

This site may use the Google Remarketing service, which makes it possible to offer Internet users targeted advertisements based on the sites visited in the Google ad network. This allows us in particular to use your browsing data on this site in order to offer you targeted advertisements when you visit other sites in the Google network. You can deactivate this functionality via the following link:

If you have a Google account and are logged in to it by visiting our site, and you have authorized Google to link your browsing history to your Google account and to use this history to personalize ads, Google will link the browsing data collected through Google Analytics to your Google account. If you use your Google account on multiple devices, our ads may appear on those other devices. Although Google collects data on this site related to the use of Google accounts, RECTOR LESAGE SAS cannot under any circumstances deduce the identity of Google account users consulting the site.

For more information about how Google collects and uses this data, we invite you to consult Google’s privacy policies:
