Protecting seller privacy
The only personal information Gumroad gives to your customers is the email address you use for your support email and the name you have entered into your profile page. 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.
In short: 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 profile page, your username, and support email.
Unfortunately, a few creators based in the countries with direct bank deposits enabled have found that on rare occasions the name and/or phone number entered into their payout settings have been displayed on customers' credit card statements. This is not something we have control over, as the information is being directed through Stripe to the customers' card providers. The card providers are deciding what information to share.
To get around this and to remain anonymous, we suggest:
1) Creating an account based in a non-ACH country
2) Creating an LLC and filling out a business account
3) Creating a phone number specifically for your business and/or Gumroad using Google Voice or a similar VOiP provider
