Terms of Service

Effective: August 13, 2026

These Terms of Service (the “Terms”) are a contract between you and PropsMath (“PropsMath,” “we,” “us,” or “our”) governing your access to and use of propsmath.com, related applications, and the model-probability estimates, track record, research, and other content we make available (together, the “Service”).

By creating an account, checking a box indicating that you agree, purchasing a subscription, or otherwise accessing paid features of the Service, you agree to these Terms. If you do not agree, do not use the Service.

The Privacy Policy and Refund Policy are incorporated into these Terms.

1. What the Service is — and is not

PropsMath is a quantitative sports-forecasting publication. We publish model probability estimates (including the PropsLock model), supporting research, and a public, loss-inclusive track record of those estimates after events resolve.

The Service is for research and informational purposes. It is not a sportsbook, bookmaker, casino, prediction market, broker, or betting exchange. We do not: accept wagers or bets of any kind; hold customer funds for wagering; place, broker, solicit, or facilitate bets; take sportsbook, casino, or prediction-market affiliate revenue; or guarantee that any event will occur, that any model probability will match a future result, or that you will profit from any use of the Service.

A model probability is a statistical estimate produced by our models. It is not a pick, tip, instruction, or suggestion to wager, and it is not a statement of a sportsbook’s price or of what you should do. You decide what, if anything, to do with the information. Any activity you undertake with third parties is solely between you and those third parties.

Past model performance does not predict future results. The public track record reports historical, graded model output, including misses. It is not a promise that future estimates will be accurate or that subscribers will achieve any particular result.

2. Eligibility

You may use the Service only if:

  • You are at least 21 years old. We apply this age floor as a condition of use, including in places where a lower age would suffice to form a contract. We may ask you to self-attest your date of birth. We do not store the date of birth; we store only that you were verified as 21 or older and the time of that verification. If you are under 21, you must not use the Service. We will refuse an under-age attempt and will not retain that attempt.
  • You have the legal capacity to enter a contract.
  • You are not located in a jurisdiction we have restricted (see Where we offer the Service) and you are not using the Service where we have prohibited it.
  • You are not barred from receiving services under US law (including trade sanctions).
  • If you use the Service on behalf of an organization, you have authority to bind it, and “you” includes that organization.

The Service is not directed to children. We do not knowingly collect personal information from anyone under 13. We may suspend or close an account if we reasonably believe these conditions are not met.

3. Accounts

You must provide accurate account information and keep it current. You are responsible for activity on your account and for keeping your credentials confidential. Notify us at jeremyw0815@icloud.com if you believe your account has been misused.

We may refuse, suspend, or close an account, or limit features, if you violate these Terms, if payment fails, if we are required to do so by law, or if we reasonably believe the account poses a legal, security, or abuse risk.

4. License, IP, acceptable use

We grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to access the Service and view model probability estimates for personal, non-commercial research and informational use, subject to a current paid subscription where required.

You may not, except as we expressly permit in writing:

  • scrape, crawl, harvest, or systematically download estimates or track-record data (manual, reasonable browser viewing is fine);
  • republish, resell, redistribute, or commercially exploit forecasts;
  • share paid access or credentials;
  • reverse engineer the Service except where a non-waivable law allows;
  • interfere with the Service, bypass limits, or circumvent geographic, age, paywall, or authentication controls;
  • use the Service to build a competing forecasting product;
  • misrepresent an estimate as a sportsbook line, as our instruction to wager, or as official league or NCAA output;
  • use the Service for any unlawful purpose.

We own the Service, models, software, and related intellectual property. Feedback you send may be used without obligation to you. League and athlete names appear as nominative references.

5. User conduct

You may not manipulate model inputs, grading, or the public track record. You may not provide a false age, location, or identity, or use unauthorized payment methods. You may not upload malware or unlawful or harassing content. You may not use the Service in connection with match-fixing, non-public insider contest information, or any scheme to influence an event’s outcome.

6. Subscriptions, billing, cancellation

Paid access is a subscription. Prices, term, and plan contents are shown at checkout and on the pricing page. Charges are in US dollars, excluding taxes we must collect.

Your subscription renews automatically at the then-current price until you cancel. By subscribing you acknowledge the plan name, price, and billing frequency, and that charges recur until you cancel; authorize us and Stripe to charge the initial term and each renewal; and agree we charge the renewal fee at the start of each new term unless you cancel before that charge. We disclose these terms before collecting billing information and will not charge without affirmative consent at checkout.

You may cancel anytime in account settings, or by email if you cannot access the account. Cancellation must be available online, at will, without obstructing extra steps. If we present a retention offer, you must still be able to cancel immediately. Cancellation stops future renewals. Access continues through the paid term unless a refund applies. Canceling is not a refund request except as the Refund Policy provides.

If a payment fails, we may retry, suspend paid access, or cancel the subscription. We will give notice of material price or term changes as required by law. Continued use after a noticed price change is agreement except where law requires new consent.

Stripe processes payment. We do not store full card numbers.

7. Refunds

Refunds are governed by the Refund Policy, which is incorporated into these Terms. In summary: new subscribers may request a full refund within 7 days of the first payment; monthly subscriptions may be canceled anytime and run through the current period; annual subscriptions may receive a prorated refund within the first 30 days, then continue through the current annual period; Stripe typically returns funds in 5–10 business days. If this summary and the Refund Policy conflict, the Refund Policy controls the mechanics.

8. College sports

We may publish estimates for college football and other collegiate contests. PropsMath is not affiliated with, endorsed by, or sponsored by the NCAA or any conference, school, or governing body. Names appear as nominative references only.

9. Track record

The public track record includes misses. Historical descriptions are not a guarantee. An anonymous calibration log of published estimates and outcomes, without name or account identifiers, is retained even if you delete your account.

10. Where we offer the Service

We may restrict accounts or paid features. As of the effective date, we block paid and logged-in use from Washington State, based on location signals including IP-based headers from our hosting provider. We may add or remove jurisdictions later. Legal pages remain reachable from restricted regions. These are our operating rules, not a legal opinion we ask you to render.

You may not use a VPN or proxy to evade these restrictions. Location signals can be imperfect; we do not warrant complete detection. We may close or refuse an account in a restricted region and refund unused prepaid fees as the Refund Policy or law requires. Void where prohibited.

11. Third-party services

The Service uses Clerk, Stripe, and analytics processors described in the Privacy Policy. We are not responsible for third-party services we do not control.

12. Termination, deletion, survival

Account deletion works as described in the Privacy Policy. We first cancel any Stripe subscription, including subscriptions in past_due or incomplete status. If cancellation cannot complete, we will not treat the account as deleted — we fail closed on billing. After deletion we delete or de-identify personal information as in the Privacy Policy, except records we are required to keep. Anonymous calibration-log entries remain.

We may terminate or suspend access for a Terms violation, discontinuation of the Service, legal requirement, or risk. If we discontinue the Service for convenience, we refund prepaid unused fees as required.

Provisions that by their nature should survive termination do survive, including characterization of the Service, license restrictions, intellectual property, refunds, college sports, track record, geographic restrictions, disclaimers, limitation of liability, indemnity, governing law, and miscellaneous terms.

13. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. We do not warrant the accuracy, completeness, or timeliness of estimates; that the Service will be uninterrupted, secure, or error-free; that the track record is error-free; or that the Service is available in every location. Estimates may not reflect later market prices or information. Nothing we publish is financial, investment, legal, or betting advice. We are not your advisor. Some states do not allow disclaimer of implied warranties; in those states we disclaim to the maximum the law allows.

14. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, data, goodwill, or business, even if advised of the possibility. Our total liability is limited to the greater of the amounts you paid us in the 12 months before the claim or US $50. These limits do not apply where state law forbids them (for example, certain fraud or personal-injury claims). They apply in contract, tort (including negligence), strict liability, or otherwise.

15. Indemnity

You will indemnify PropsMath and its owners, officers, employees, and contractors against claims arising from your misuse of the Service, your violation of these Terms, your violation of law, or your republishing or commercial reuse of estimates. We may assume exclusive defense of a claim; you will cooperate.

16. Governing law and disputes

These Terms are governed by the laws of North Carolina, without conflict-of-law rules that would apply another state’s law. Nothing here deprives you of non-waivable consumer-protection rights of the state where you live.

Exclusive venue is the state courts in Henderson County, North Carolina, or the U.S. District Court for the Western District of North Carolina, except that we may seek provisional relief for intellectual-property or confidentiality claims in any court of competent jurisdiction. We do not require arbitration and do not ask you to waive class actions or a jury trial. Claims must be brought in an individual capacity unless a court determines otherwise. Consumer home-county venue rights that cannot be waived are not waived.

17. Changes

We may update these Terms. We will post the updated Terms on this page and change the effective date. For material changes, we will give notice a reasonable time before they take effect, except for changes required for legal compliance. If you do not agree, cancel and stop using the Service before they take effect. Continued use after the effective date is acceptance.

18. Notices

We may notify you via the email on your account or by posting on the Service. You send legal notices to: PropsMath, Hendersonville, North Carolina, jeremyw0815@icloud.com.

19. Miscellaneous

These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and us about the Service. If a provision is unenforceable, the rest remains in effect. Silence is not a waiver. You may not assign these Terms without our consent; we may assign them in a merger, sale, or reorganization. There are no third-party beneficiaries. We are not liable for delay or failure caused by events beyond our reasonable control. Headings are for convenience. “Including” means including without limitation. You must comply with export and sanctions laws. If you are a US government user, the Service is commercial software and data, and you receive only the rights these Terms grant.
