Cookie Policy




1 – Object 

The First-id company has developed a solution allowing website and mobile application publishers to have a unique identifier for each of their visitors, for the purpose of improving the browsing experience, through the personalization of content. and advertisements displayed to you.

When you browse the sites and applications linked to First-id, subject to your explicit consent, First-id may assign you a unique identifier generated randomly and stored in a cookie associated with the First-id domain. This identifier is then sent to publishers who can use it to get to know you better. 

First-id also implements processing consisting of operating a platform for purchasing advertising space, based on standardized technologies within the advertising ecosystem. These two processing operations are described below and are partly based on cookies.

What is a cookie” ?

A “cookie” is a series of information, generally small in size and identified by a name, which can be transmitted to your browser by a website to which you connect. Your web browser will keep it for a certain period of time, and send it back to the web server each time you reconnect to it. Cookies have multiple uses: they can be used to memorize your customer identifier with a merchant site, the current content of your shopping cart, an identifier allowing you to trace your navigation for statistical or advertising purposes, etc.

2 – Processing of creation and transmission of a unique identifier

​a) What does this treatment consist of?

​
When a visitor comes for the first time on a site linked to First-id, and once he has explicitly consented, his browser is redirected to the First-id portal which will determine if he already has a number of identification or if it is necessary to create one for him.

The number will then be transmitted to the publisher of the site consulted, which will generally store it in a cookie and use it for its own purposes of monitoring the navigation of Internet users.

This redirection is of the order of a few milliseconds, and therefore invisible to the visitor. This processing, carried out under the processing responsibility of the company First-id, is intended to create and transmit to site and application publishers a unique identifier allowing you to track your browsing.

b) What does the First-id identifier look like? 


The main characteristics of the identifier generated by First-id are as follows:

  • 32 randomized characters, with no special characters,
  • No sharing of user information between Clients,
  • Anonymisation of information collected by technical intermediaries.

Example of a First-id unique identifier: aevyknye48g9rx5328jr29839655w5pg

c) What personal data does First-id process?

​
​First-id processes the following categories of data:
When creating the identifier, First-id may take into account certain information to determine the identity of the Internet user, if this information is sent by the Client: 

  • IP address (V4 and V6) and publisher domain from the site on which this information was collected,
  • User Agent and technical informations relating to the terminal used, such as RAM, number of processors on the user’s terminal and screen resolution,
  • Ahashed email addresses (only if the email opt-in for their advertising use has been obtained) and the source publisher of the e-mail,

e) What are the retention periods?


The online advertising and web analytics ecosystem generally keeps browsing data and identifiers associated with Internet users for a minimum period of 13 months. In the case of web analytics, for example, this period provides statistics covering an entire year + one month, so that trends can be estimated over more than one year.

This retention period is applied to the identification of the Internet user by First-id.

The retention period for each identifier on each site depends on the duration indicated by each site.

f) What is the legal basis used by First-id?
