Creators can use any name of their choice to appear on their Buy Me a Coffee profile. We also do not give out a creator's email address for any reason.
However, we cannot keep the creators' actual names or email addresses from appearing on bank statements of the transactions.
If you conduct your transactions through PayPal, you can consider creating a new email account and linking your existing PayPal account with it. Thus you can have the name of your choice on the payment page.
If you are using Stripe, you can enter any name of your choice in the Business Name field, while setting up your Stripe account.
