What is the purpose of private browsing?

This type of browsing allows browsers not to store information about the sites we visit and therefore show us more "unaltered" information, that is, without taking into account our preferences or tastes. In normal browsing mode, browsers analyze the sites you have visited before to show you information in one form or another.
