What does the 12-month window mean?

It is a purchase, not a subscription

Both offers are one-time payments. Nothing renews automatically and there is no card kept on a plan.

What the twelve months cover

Counting from your purchase date:

• One path. Content updates to that path, and the AI features (the tutor, coached build labs, and checkpoint reasoning) on that path.
• Trailblazer (all paths). Every path available when you bought, plus new paths and content updates released inside the window, with the AI features on all of them.

What happens after

Everything you unlocked, including updates you received inside your window, stays open in your account. You keep reading, keep your progress, and keep your own work. What ends is the update entitlement and the AI features. If you want AI features again, you make a new purchase; we do not renew you automatically.

Free accounts have no update entitlement.

Update notes

When we release an update to a path you own, it comes with a step-by-step summary of what changed so you can decide whether to adopt it. We do not promise how often updates ship.

The exact terms are in the Terms of Service, section 8.
