Can I backup my BATs from the Android and put in the desktop version of Brave?!

I won’t use Android anymore, so no need to keep Brave there. I have some BATs, from the last month in my wallet (about 1.500 BATs) and more 1 BAT waiting to be added until 5 or 6 of June, from May. If I backup everything, will I lost everything from the wallet and only keep my latest BAT yet to be paid or everything will be backed up?!

Do I need to use sync or something? I know Brave does generate a code for it to be generated. Not sure if everything goes with it or just part of the BATs. Also, I still don’t have +25 BATs to have my own wallet…
