Terms of Service

Last updated: June 10, 2026

These Terms of Service (“Terms”) govern your access to and use of Nummmbers (nummmbers.com) and its courses, including Make Math Mine (collectively, the “Service”), operated by Third Technology LLC (“we,” “us,” or “our”). By creating an account, accessing, or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Eligibility and Geographic Restrictions

By creating an account or using the Service, you represent and warrant that:

  • you are at least 18 years of age;
  • you are not located in, under the control of, or a national or resident of any country or region subject to comprehensive U.S. economic sanctions, including without limitation Cuba, Iran, North Korea, Syria, or the Crimea, Donetsk, Luhansk, Kherson, or Zaporizhzhia regions of Ukraine;
  • you understand that we may decline or restrict access from other regions subject to U.S. sanctions or where providing access would create a material compliance burden, including Russia and Belarus;
  • you are not listed on any U.S. government list of prohibited or restricted parties, including the U.S. Treasury Department's Specially Designated Nationals (SDN) List or the U.S. Commerce Department's Denied Persons List; and
  • you will not use the Service in violation of any applicable export control or sanctions laws.

We reserve the right to restrict or terminate access from any region at our discretion, including in response to changes in applicable law. Where we identify access from a restricted region, we will block access; however, the obligation to comply with applicable law rests with you.

2. Accounts

To access most features of the Service, you must create an account. You agree to provide accurate, current, and complete information and to keep that information up to date. You are responsible for safeguarding your account credentials and for all activity that occurs under your account.

You may not share your account, allow another person to use it, or create more than one account for yourself. You must notify us promptly if you suspect unauthorized use of your account.

3. Subscription, Billing, and Refunds

Some features of the Service are offered on a paid subscription basis. By starting a paid subscription, you authorize us and our payment processor (Stripe, Inc.) to charge the payment method on file at the rates and intervals disclosed at checkout.

Automatic renewal terms. Paid subscriptions renew automatically at the end of each billing period at the then-current price and interval disclosed at checkout, charged to the payment method on file, until you cancel. You may cancel at any time through your account settings; cancellation takes effect at the end of the current billing period and you will retain access until then. Cancellation immediately stops future charges. For annual subscriptions, we will send a reminder before each renewal.

All sales are final. Except where required by applicable consumer protection law, we do not refund subscription fees. The Free tier gives you full access to all ten phases of curriculum and unlimited practice in preset interests with no daily caps. Try it before subscribing.

If you were billed in error (duplicate charge, accidental sign-up within 24 hours, or a billing system bug), email support@nummmbers.com and we will fix it.

4. AI Features and Educational Content

The Service uses large language models (provided by Anthropic, PBC and potentially other AI providers) to generate explanations, hints, feedback, and personalized practice problems. AI-generated content can contain errors, including factual mistakes, mathematical errors, or biased framing.

The Service is provided for educational purposes only. It is not a substitute for accredited instruction, professional tutoring, or formal credentialing. We do not guarantee that use of the Service will result in any particular learning outcome, test score, or credential.

You should independently verify any information that materially affects an academic, professional, or financial decision. We are not responsible for decisions made in reliance on AI-generated output.

We do not use Your Content (as defined in Section 7) to train or fine-tune AI models. If this changes, we will notify you in advance and you will have an opportunity to opt out before that change takes effect.

5. Acceptable Use

You agree not to:

  • use the Service for any unlawful purpose or in violation of any applicable law or regulation;
  • attempt to gain unauthorized access to the Service, other accounts, or our infrastructure;
  • interfere with or disrupt the Service, including by overwhelming our systems with automated requests;
  • reverse engineer, decompile, or attempt to extract the underlying code, models, or training data of the Service;
  • scrape, harvest, or extract content from the Service in bulk, whether by manual or automated means, except (a) as expressly permitted by us in writing or (b) where you are exporting your own personal information in exercise of a privacy right described in our Privacy Policy;
  • resell, sublicense, or commercially redistribute the Service or its content;
  • submit content that is unlawful, harassing, defamatory, or infringes the rights of others;
  • attempt to elicit harmful, illegal, or policy-violating output from AI features, or use AI features to generate such output.

6. Fair Use and Rate Limits

Our paid plan is offered for personal, single-account use. Lessons and Free Practice in preset interests have no usage limits. AI-powered features (the tutor, Teach Me This, and bespoke practice generation) include generous hourly and monthly usage allowances, set well above the level any individual learner can reasonably reach. Monthly allowances reset on the first of each calendar month and may change as the Service evolves.

During periods of unusually heavy use, we may serve AI responses from a faster model. The Service is not designed for and is not licensed for automated, machine-generated, or industrial-scale usage.

We reserve the right to apply rate limits, temporarily restrict access to specific features, require additional verification, or, for repeated or clearly abusive behavior, suspend or terminate the account, in each case at our discretion and in accordance with applicable law. If you believe you have hit a limit by mistake, contact support@nummmbers.com and we will review.

7. Your Content

You retain ownership of any content you submit to the Service, including answers, questions, written reflections, and uploaded materials (“Your Content”).

You grant us a worldwide, non-exclusive, royalty-free license to host, store, process, and display Your Content solely as necessary to operate and improve the Service for you. You also grant us the right to use de-identified, aggregated information derived from Your Content (information that cannot reasonably be used to identify you) for analytics, product improvement, and research.

You represent that you have all necessary rights to submit Your Content and that it does not violate the rights of any third party.

Copyright complaints (DMCA).If you believe that content available through the Service infringes your copyright, you may send a notice under the Digital Millennium Copyright Act, 17 U.S.C. § 512, to our designated agent at support@nummmbers.com. Our DMCA Policy lists the designated agent’s full contact details and the counter-notice process. Your notice must include:

  • a physical or electronic signature of the copyright owner or a person authorized to act on their behalf;
  • identification of the copyrighted work claimed to have been infringed;
  • identification of the material that is claimed to be infringing and that you want removed, with information reasonably sufficient for us to locate it;
  • your contact information, including address, telephone number, and email;
  • a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and
  • a statement, made under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on their behalf.

If your content is removed in response to a notice and you believe the removal was a mistake or misidentification, you may submit a counter-notice to the same address with the elements required by 17 U.S.C. § 512(g)(3).

We may terminate the accounts of users who are repeat infringers.

8. Our Intellectual Property

The Service, including all curriculum, lesson content, visuals, software, and design, is owned by us or our licensors and is protected by copyright, trademark, and other intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your own personal educational use. You may not resell, sublicense, or commercially redistribute the Service or its content. No other rights are granted.

9. Termination

You may stop using the Service and close your account at any time. We may suspend or terminate your access to the Service at any time, with or without notice, if you violate these Terms, create risk or possible legal exposure for us, or if we discontinue the Service. If we discontinue the Service entirely, or terminate your account for a reason other than your violation of these Terms, we will refund the prorated unused portion of any prepaid subscription fees.

Upon termination, the rights and licenses granted to you will cease. Provisions that by their nature should survive termination (including ownership, disclaimers, limitation of liability, indemnification, and governing law) will survive.

10. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS. WE DO NOT WARRANT THAT AI-GENERATED CONTENT WILL BE ACCURATE OR APPROPRIATE FOR ANY PARTICULAR PURPOSE.

11. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE OR OUR OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE.

OUR TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (a) THE AMOUNTS YOU PAID US IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY OR (b) ONE HUNDRED U.S. DOLLARS ($100.00).

The foregoing limitations do not apply to liability that cannot be limited or excluded by applicable law, including liability for fraud, gross negligence, willful misconduct, personal injury caused by our negligence, or violations of consumer protection statutes that grant non-waivable rights.

12. Indemnification

To the extent permitted by applicable law, you agree to defend, indemnify, and hold harmless us and our affiliates from any third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to (a) Your Content, (b) your breach of these Terms or the Acceptable Use restrictions in Section 5, (c) your infringement or violation of the intellectual-property, privacy, or other rights of any third party, or (d) your unlawful use of the Service. We will give you prompt written notice of any claim for which we seek indemnification and reasonable cooperation in the defense.

13. Governing Law and Disputes

Informal resolution first. Before filing a claim against the other, you and we each agree to first try to resolve the dispute informally. You can start that process by emailing support@nummmbers.com with a description of the dispute and how you would like it resolved; we will do the same by writing to the email address on your account. If the dispute is not resolved within 30 days of that notice, either party may bring a formal claim.

These Terms are governed by the laws of the State of California, without regard to its conflict of laws principles. You agree that any dispute arising out of or related to these Terms or the Service will be brought exclusively in the state or federal courts located in Sacramento County, California, and you consent to the jurisdiction of those courts.

14. Miscellaneous

Severability. If any provision of these Terms is held to be invalid or unenforceable by a court of competent jurisdiction, that provision will be enforced to the maximum extent permitted, and the remaining provisions will remain in full force and effect.

No waiver. Our failure to enforce any right or provision of these Terms will not be deemed a waiver of that right or provision. A waiver is effective only if set out in a writing signed by our authorized representative.

Assignment. You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent. Any attempted assignment without consent is void. We may assign these Terms, in whole or in part, to any successor in interest by operation of law or otherwise.

Force majeure. Neither party will be liable for any failure or delay in performance under these Terms (other than your payment obligations) to the extent caused by circumstances beyond reasonable control, including acts of God, war, terrorism, civil unrest, pandemic, government action, labor disputes, internet or telecommunications failures, or failure of third-party service providers, including our hosting, database, payment, and AI providers.

Entire agreement. These Terms, together with the Privacy Policy and any policies referenced herein, constitute the entire agreement between you and us with respect to the Service and supersede all prior or contemporaneous agreements, understandings, and communications, whether written or oral.

15. Changes to These Terms

We may update these Terms from time to time. When we do, we will post the updated Terms here with a new effective date, and for material changes we will also show a notice in the app before they take effect. Your continued use of the Service after the effective date constitutes your acceptance of the updated Terms.
