Terms of service

Last updated 7 September 2026.

1. Who you are dealing with

Find the Heir, at findtheheir.com, is operated by Snowy Mountain Software, a trade name of ZYEYZ, LLC, a limited liability company in Montana, United States. "We" and "us" mean that company. "You" means whoever is using the site. Using the site means you accept these terms; if you do not accept them, please do not use it.

2. What the product is

A Find the Heir book is a puzzle: a fictional county register of births, and a bundle of solicitors' memoranda that each rule somebody out. Strike out everybody the memoranda exclude and exactly one entry is left standing. You get the book as a PDF you can print, and a solving surface on this site that keeps your strikes and your notes.

Every name, parish, firm, estate and county in a book is invented. Nothing in a book refers to a real person, living or dead, or to a real estate, inheritance, or legal matter. A book is not a genealogical record and is not research.

3. Where the site is up to

The site is open: anybody can create an account and the books are for sale. This is a small product run by one person, so if something is wrong, writing to us is the fastest way to have it fixed.

4. Accounts

An account needs a working email address, and you are responsible for keeping your password to yourself and for what happens under your account. You must be at least 13 years old, or the age of digital consent where you live, whichever is higher. One account is one person; please do not share or transfer it. We may suspend or close an account that is used to break these terms.

The free sample needs no account. It is kept against your browser session, so clearing your cookies clears your progress on it, and it is not backed up.

5. What you may do with a book you have bought

A book you buy is yours to keep and to use, personally and indefinitely. You may print it as many times as you like, on paper or to a file, and you may write on it, mark it, and solve it with anyone you like sitting beside you.

What you may not do is redistribute it: do not post the PDF publicly, sell it, lend it out as a file, or put it on a file-sharing service. Each exclusive book is drawn for one buyer, and the copy you receive is identifiable as yours. We keep the copyright in the books, the register data, the memoranda and this site; buying a book buys a license to use that copy, not ownership of the work.

Shared editions, which are marked as such, are the exception in one direction only: many people hold the same book, so it is not unique to you. The rest of this section still applies to them.

6. The answer

A book has exactly one heir and the site never tells you who it is. The verification tool answers only "yes" or "not this one", which is what the checksum printed in the book already tells you. That is deliberate, it is the product, and asking us for the answer to a book you have not finished will get you a polite no.

7. Buying, and the price

Payment is handled by Stripe, on Stripe's own pages. Your card details go to them and never to us: we do not see, store or process a card number at any point, and we could not produce one if we were asked.

The price charged is the price shown on the product page at the moment you check out. Those are the same number by construction, not by our remembering to keep them level: the site reads the price back from Stripe before it will open a payment page at all, and refuses to sell you anything if the two ever disagree.

A purchase is for one book, once. There is no subscription and nothing renews, and the site refuses to build a payment page for anything that would.

Buying one of the two sizes gets you a book of that size, drawn for you out of stock we keep ahead of demand. You do not choose which one, and nobody else is ever sold the copy you get. If that stock has run out in the moment your payment clears, we tell you so by email, make one, and put it in your library, and you can have your money back instead simply by asking. Shared editions, which are marked as such and bought by name, work differently: many people hold the same book.

Your address has to be confirmed before you can buy anything, because your book, your receipt and any conversation about a refund all go to it.

Refunds have their own page: see refunds. In short: fourteen days, no questions, and we do not take the book back.

8. Fair use of the site

Do not attempt to break into accounts that are not yours, to extract books you have not bought, to script the verification endpoint in order to search for an answer by brute force, or to take the site down for other people. Ordinary reading, solving and printing is what the site is for, and we do not count keystrokes.

9. What we promise, and what we do not

We promise that a book is solvable: each one is built so that exactly one register entry survives every memorandum, and the printed checksum matches that entry. If you can show us a book where that is not true, we will fix it or refund it.

Beyond that, the site is provided as it is. We do not warrant that it will be available without interruption or free of errors. To the extent the law allows, our total liability to you for anything connected with the site or a book is limited to what you paid us for that book.

10. Ending it

You can close your account at any time by writing to us. Books you have bought remain yours; ask us and we will send you the PDFs before the account goes. We may end your access if you break these terms, and we will tell you why.

11. Changes to these terms

We may update these terms. The date at the top is when they last changed. If a change matters to people who have already bought something, we will email account holders rather than change the page quietly.

12. Law

These terms are governed by the laws of the State of Montana, United States, and any dispute belongs in the state or federal courts sitting in Montana. Nothing here takes away a consumer right you have where you live that cannot be signed away.

13. Contact

Use the contact form. It reaches a real mailbox that a person reads.
