Protecting Your Privacy on Gumroad
The only personal information Gumroad gives to your customers is the email address you use for your support email and your Full Name. If you have not created a Support email, your login email will be displayed on your customers' receipts.
You can change your email information in your Settings. If you add a support email, your customers will not be able to view your login email.
Your customers will never see your banking information, payout information, or address. The only information they know about you is the Full Name you use on your account, your username, and support email.
