i dont have techincal knowledge but i found privacy hater bug let me explain to you
suppose in settings i have enabled clear all data on exit and it clears all data on exit now i use brave frequently and i visit some sites frequently for example google.com on exit everything should be cleared that i recently visited from brave browser database on my computer but i have seen that if i have pinnned brave browser on windows 10 taskbar and when i right click on it it shows recently visited websites there and i have to manually remove them, i think it is not clearing recently visited websites that i visited recently even if clear data on exit is enabled. please look into this bug
