These terms apply when you use this website or buy anything on it. The seller is MPC Holding LLC, a Utah limited liability company. Buying something means you accept these terms.
Digital products: ebooks in PDF form, and a self-paced online course of videos and written material. Nothing physical ships. Access is delivered by email and through an account on this site. Course access is for the lifetime of the product, which we intend to be indefinite; if we ever had to retire it, we would give members ninety days' notice and a downloadable copy of the material.
Your login is for you. Keep your password to yourself, and tell us promptly if you think someone else has it. One household is fine — your spouse using your login is expected and welcome. Sharing an account beyond your household, or reselling access, is not, and we may close accounts that do it.
You may read it, print it for your own use, fill in the worksheets, and use the scripts and games with your own family for as long as you like. You may quote a short passage with credit.
You may not republish it, resell it, upload it to a file-sharing site, use it to run a paid class or coaching practice, or feed it to an AI model for training. The text, the plans and the artwork are copyright © 2026 MPC Holding LLC, all rights reserved.
Prices are in US dollars and shown before tax. Sales tax is calculated at checkout based on your billing address, as the law requires. Payment is processed by Stripe under their own terms; we do not receive or store your card details. Prices can change, but never for something you have already bought.
Thirty days, on everything, no interrogation. The full policy is on the refunds page and it forms part of these terms.
This is education, not therapy, medicine, or legal advice. It describes what research has found about grandparents, families and children in general. It cannot know your family, and it is not a substitute for a doctor, a therapist, a social worker or a lawyer. If a child is in danger, or a family member is in crisis, please involve a professional rather than a workbook.
We make no promise about results. Families are not machines, and no book can guarantee that a relationship improves.
To the extent the law allows, our total liability to you for anything connected with these products is limited to what you paid for them. We are not liable for indirect or consequential losses. Nothing here limits liability for fraud or anything else that cannot lawfully be limited.
Buying something or requesting the free plan adds you to our email list, which carries a one-click unsubscribe in every message. Unsubscribing never removes access to something you purchased.
These terms are governed by the law of the State of Utah, and any dispute belongs in the state or federal courts serving Utah County, Utah. Before anyone goes to court, please write to us — almost everything can be settled by email in a day.
