Terms of access and sale

This page remains a private-review draft until the actual seller identity, checkout provider, refund flow, support path, and jurisdiction-specific disclosures are verified.

Early Access

Purchase includes the files available at the time of purchase. Minor corrections may appear only in the public errata. After verifying an active, non-refunded purchase, Readude may at its discretion provide a replacement package for a material correction through support. Automatic, continuous, and lifetime updates are not promised, and a later edition may be a separate product.

Educational scope

The content is not a cryptographic audit, production-security approval, legal advice, tax advice, investment advice, or financial advice.

Liability and warranties

Final limitations must be reviewed for the seller's actual jurisdiction. Nothing on this draft page excludes rights that cannot lawfully be excluded.
