Cookies delete in all sites / problem

Hi everyone. I downloaded Brave Browser a few days ago and i’m in love with it. I’m not agree that i can’t add a google account but isn’t important. The thing that is important and doesn’t work is correlated at cookies. I have active the option that when i quit from browser it delete all cookies and data navigation. My problem is that i want to stay connected to gmail and google and youtube and other few sites. I want to ask if exist a type of “whitelist” so the browser delete all information but not the information of the sites that i put in the “exception whitelist”. Is very busy do the re-log everytime and not be able to see the notifications of gmail. Please help.
