Question on privacy: Unlinking Binance to Binance TH

Binance TH requested entry to Binance.com account when you link the accounts. Whenever you do this, it says it 'sees your binance wallet stability'.

I want to understand how this info is shared and with. whom, and learn how to choose out from this. Is it potential to unlink the accounts once you link or it's essential create a new one?

Looks like a huge privacy and security danger, especially considering the historical past of knowledge leaks and knowledge being bought in Thailand, criminals concentrating on individuals here for kidnappings and crime.

Would respect any insights on this /u/BinanceCSHelp thanks
