Does Binance need my ID?

Could you please explain to me, does Binance require me to provide my ID? I'm a bit concerned about the privacy aspect of this. Could you elaborate on the reasons why they might need it? Also, how secure is the process of submitting my personal information to Binance? I'd like to know if there are any specific measures taken by Binance to ensure the safety of my data. Additionally, is it mandatory for all users to provide their ID, or are there certain circumstances where it's not required? Thank you for clarifying these points for me.
