Terms of Use & Access Policy

Only the person who purchased the book may redeem the code. Proof of purchase may be requested at any time. Redemption by any other party is a violation of these terms.

The book is sold in seven SKUs. All prices are in Euros (EUR) and inclusive of applicable VAT where required. Final checkout price may vary by gateway and region.

Each code is a 20-character alphanumeric string printed on the inner back cover of a physical copy (or delivered by email for direct purchases). Codes are one-time use and are bound permanently to a single GitHub account upon redemption. Codes are non-transferable and non-resellable; selling, gifting, or otherwise transferring a code to another person is a violation of these terms.

Successful redemption grants read-only access as a GitHub collaborator on the private companion repository (or repositories) for the SKU you purchased. Bundle codes grant access to all component volumes in the bundle. Access is at the GitHub-account level and does not depend on your email address.

The code and all linked content are provided for educational and simulation purposes only. Redemption does not constitute a commercial license to build, operate, deploy, or sell products based on the book's material without a separate written commercial license from the Publisher. All code in the repositories is source-illustrative and must not be treated as production-ready software.

The accompanying repositories are released under a non-commercial educational license. You may read, clone, and reference the code for personal study and adaptation in your own private projects. You may NOT:

• Build, operate, or resell products or services based on repository content
• Redistribute repository code publicly or to third parties
• Use repository content as the basis of a commercial training course or product

For commercial licensing inquiries, contact support@thebackendofluck.com.

While you have access to the repositories, you may NOT:

• Resell, sublicense, or share your access code with any third party
• Clone and publicly re-publish repository contents in whole or in part
• Use automated tools to scrape, mirror, or bulk-export repository content
• Attempt to bypass revocation controls or re-invite yourself after revocation
• Share your GitHub credentials with another person to circumvent the one-account limit

We may revoke access immediately upon:

• Chargeback, payment dispute, or refund of the original purchase
• Detection of code resale, unauthorized sharing, or credential transfer
• Any violation of the acceptable use policy above
• Abusive behavior toward support staff
• Any applicable law requiring termination

Revocation removes you as a GitHub collaborator within 5 minutes of the triggering event (automated webhook).

If you need to rebind your code to a different GitHub account, email support@thebackendofluck.com with subject "Access Reset Request" and your purchase reference. Resets are limited to 3 per buyer; requests beyond that limit require manual review.

For audit and anti-fraud purposes we store: github_login, github_user_id, email, redeemed_at, ip, user_agent, and purchase_reference. Redemption records are retained permanently for audit integrity; the audit log is retained for 7 years.
