Refund Policy

Last updated: August 4, 2026

Because downloadable files are delivered immediately, purchases are generally final after access or download is provided, except where applicable law requires otherwise.

We will review

• A duplicate purchase of the same product.
• A corrupted or inaccessible file that support cannot replace.
• A checkout error that charged an incorrect amount.

Before purchasing

Please review the product description, intended audience, table of contents, update date, and preview when one is available.

Technical delivery problems

Report a delivery or file-access problem within 14 days of purchase. Include the buyer email address, order reference, and a description or screenshot of the issue.
