Brave Sync doubts

Hello, I have doubts regarding the synchronization. I understand that my data does not exist on any server, therefore I assume that if I log in to my notebook, the data is obtained from my PC?.

So, that means that in the case of formatting both computers at the same time, my synchronization data would be lost, since they would not have any origin from which to be obtained after installing the first Brave… is this correct?

Thank you for clarifying this issue and greetings to the community. :+1::+1::+1::+1:
