Does Cloudflare share payment methods between Users?

If I enter my payment information into another person's Cloudflare account while logged in under my own user account... will they be able to see that payment info / use it in the future for other projects?

Is the payment information saved as an account wide payment method, or is it tied only to my user account and only I can see it / use it? And do the rules change for user types (Super vs non)?
