Footer content

Hello, I created the pages: - Politique de Confidentialité - Mentions Légales The url links have been inserted at the bottom of the footer. I don't know how to prevent these 2 pages from appearing in the menu (header). For the moment I have put these 2 pages in "private", but this is not the right solution because suddenly, when I click on the url links at the foot of the page, it no longer works. How to do it please?
