Is Ko-fi Anonymous/Confidential?
Only your Ko-fi display name is publicly shown on Ko-fi not your real name or email address. At the payment stage, Ko-fi hands over directly to PayPal (or Stripe) to make a direct payment from the supporter to the creator. Ko-fi doesn't get in the middle of the transaction and we don't take any fee from the transaction.
Depending on your PayPal setup, PayPal may show your Name and email on their 'checkout' page and dashboard. It's possible to set up a new email account and associate that with your existing PayPal account if you don't want to your current PayPal email address to be visible. Your PayPal account can have multiple email addresses associated with it so no need to delete your current email address.
To choose your own display name and email address you can switch your PayPal from a Personal account to a Business account for free. With a business account you can change your name to a business display name and your email address to a business email.
