Refund Policy
Last updated: May 19, 2026
Pre-Orders
You may cancel a pre-order and receive a full refund at any time before the Book is delivered in June 2026. To cancel, contact us at the email below or request a refund through your Gumroad receipt.
Digital Editions (PDF and EPUB)
Digital books are non-returnable by their nature: once downloaded, they cannot be returned in any meaningful sense. However, if the file is defective, fails to open, or materially differs from the description on this site, you may request a refund within fourteen (14) days of delivery by contacting us with your order number and a brief description of the problem. Refunds are issued at our discretion through the original payment processor.
Kindle Purchases
Refunds for Kindle editions are handled by Amazon under their standard return policy. Please contact Amazon Customer Service for assistance with Kindle refunds — we are unable to process them on Amazon's behalf.
Paperback Purchases
Paperback editions sold through Amazon follow Amazon's standard return policy, typically thirty (30) days from delivery. Please initiate returns through your Amazon order page.
Processing Time
Approved refunds are typically processed within 5–10 business days, depending on your payment method and bank.
