Terms
Model estimates for entertainment. Not a prediction or a guarantee.
What Propper is
Propper shows model estimates for NHL player props: for each prop, the chance the model gives it and what the book is paying for it. Every number is an estimate, for entertainment. It is not a prediction, not a guarantee and not betting advice, and no outcome is promised. The book tells you the payout, Propper tells you the estimated chance, and what you do with that is your decision.
Who can use it
You must be at least 18, and old enough to bet legally where you live, which is older in many places (19 in most of Canada, 21 in most US states). You are responsible for complying with the law where you live, including any rules on sports betting.
Subscription and the Founding price
Propper is a paid subscription, monthly or yearly, billed through Whop. Founding members pay CA$4.99 / month and keep the Founding price for the 2026-27 season while their subscription stays active. If a Founding subscription lapses, the price in force at the time applies to a new one.
Billing and cancellation
You are billed in advance, monthly or yearly, until you cancel. You can cancel at any time from your Whop account; you keep access to the end of the period you have paid for and are not billed again. For a refund, reach us through the contact page.
Your account
You sign in through Whop, with Google or another sign-in provider Whop supports. An account is for one person: do not share your sign-in or your connector access with anyone else. You are responsible for what happens under your account.
Data and odds
Odds, schedules, lineups and stats come from third parties. They are shown for information, can lag the books and can be wrong; check the price at the book before you bet. Scraping Propper, copying its data or estimates in bulk, or redistributing them is against these terms.
The record
The record is Propper's own scorecard. Every estimate the model publishes is logged when it is made, then settled against what happened in the game and against the closing line at the books. Wins and losses are both kept, nothing is edited after the fact, and the page is open to everyone. Nothing on it is a real bet, and past results say nothing certain about the next game.
The connector and the API
Connecting Propper to Claude or another MCP client lets that client look up the same estimates, for your personal use; it cannot change anything in your account or place a bet. Access is rate-limited and may be paused for abuse.
Changes to these terms
