The “Presidential Tinder”

Once the most downloaded application in France when it was released on January 2, Elyze aims to be a “Presidential Tinder”an application that takes up the famous principle of “swipe” but which, instead of offering you a partner, submits to you… electoral proposals.

The goal, according to its creators: to help undecided voters find their ideal candidate for the presidential election. Thus, anonymized proposals follow one another on your phone, which you can choose to swipe on the right of your screen if you like them, on the left, if you don’t like them, or in the center, if you haven’t decided yet.

For his part, Jean-Luc Mélenchon was surprised on Twitter by the fact that, even if you agreed 100% with all the candidates, Elyze offered you Emmanuel Macron as the ideal candidate. “A fairly classic concern in computer science that relates to sorting algorithms”deciphers Mathis Hammel, for whom the real problem of the application remained however the future of the collection of personal data of users, which could raise fears of potential resale.

A problem to which the founders of Elyze finally responded by announcing the deletion of user data and the open source of the application, for more transparency. Shortly before, the Cnil (National Commission for Computing and Freedoms) had announced that it was looking into the application to verify that it was in compliance with the regulations on this sensitive data.
