Frequently Asked Questions

Where do I find my code?

Your code is printed on the inner back cover of your physical book — a 20-character alphanumeric string in the format TBOF-Vx-XXXX-XXXX-XXXX-XX. The same location is used for all four volumes; look for the dotted-border box near the centre of the inner back cover, beneath a scratch or peel sticker.

Illustrations are representative. Your actual book's printed code may vary slightly. Real photos will replace these once the first print run ships.

Can I request a replacement if the code is damaged?

Yes. Email support@backendofluck.com with a clear photo of the damaged code area and your proof of purchase (order confirmation, receipt, or Amazon order page). We'll verify ownership and issue a replacement code within two business days.

I bought through Amazon — how do I redeem?

Same flow as a direct purchase. Open your book, copy the code from the inner back cover, and redeem it here.

I bought on thebackendofluck.com — how does it work?

The code is auto-delivered to your email. Click the link in the email, sign in with GitHub, and you're done.

Can I share my code with a friend?

No. One code grants access to one GitHub account only. Codes are personal and non-transferable.

I lost access to my GitHub account. Can I reset the redemption?

Yes. Email support@backendofluck.com with proof of purchase and we'll assist.

I changed employer and lost my old email — do I lose access?

No. Access is tied to your GitHub account, not your email. As long as you keep the GitHub account, your access stays.

Can I resell my code?

Codes are non-transferable. Reselling voids access and may trigger revocation.
