Do you need SSN for Kraken?

I'm curious, does Kraken require users to provide their Social Security Number (SSN) for account creation or verification purposes? I've heard varying reports about the need for personal information on cryptocurrency exchanges, and I'm wondering if Kraken falls into that category. It's important for me to ensure my privacy is protected while still being able to access the services I need. Can you clarify their policy on SSN collection?
