What about BAT showing on startpage if I delete Brave from my laptop?

Hi team!
At the top right corner of my Brave startpage, some BAT are showing up. I have several questions as I am a neeby here :wink: :

  • if I delete (uninstall) Brave from my laptop and reinstall it, what’s happen to these BAT? Gone?
  • do the BAT showing up are automaticaly send to my verified uphold account/wallet each month?
    Thanks!
