Where to request help
For a purchase, download, access, or billing question, contact the seller through the support or contact route provided on the Gumroad product page. Include the order email or receipt details needed to locate the purchase, but never send a full payment-card number.
Digital-product requests
Because the product is delivered digitally, refund requests are reviewed under Gumroad's applicable policies, the purchase terms shown at checkout, and applicable consumer law. If the file is missing, corrupted, materially different from the product description, or you cannot access an entitled download, contact support so the issue can be investigated and corrected where possible.
What to include
A useful request identifies the product, approximate purchase date, the problem encountered, and whether you have already downloaded the files. We may ask for reasonable information to verify the transaction. Do not share private client files or confidential project information in a support request.
Abuse and chargebacks
Please contact support before initiating a payment dispute when the issue is a missing file, duplicate charge, or access problem. Nothing in this policy limits rights that cannot lawfully be excluded.
Policy changes
We may update this page when the product, delivery process, or platform terms change. The version published on this page applies subject to the purchase terms and applicable law.
