Last updated: October 30, 2026

These Terms of Service apply to your access to and use of hard-math.com. In these Terms, “Hard Math,” “we,” “us,” and “our” refer to the website administration responsible for its operation.

Please read these Terms before using the website. By accessing or using Hard Math, you agree to these Terms to the extent permitted by applicable law. If you do not agree, please discontinue using the website.

Questions about these Terms may be sent to admin@hard-math.com.

1. About Hard Math

Hard Math is an independent educational website offering mathematics practice, answer explanations, and study materials, including resources related to school mathematics, SAT preparation, and AP subjects.

The main educational materials are available without registering an account. We do not currently provide user profiles, public comments, or private messaging between visitors.

The website supports independent study and teaching. It does not replace an accredited course, a teacher’s assessment, or the official information provided by your school or examination organization.

2. Educational content and practice results

We aim to provide clear, accurate questions, answer keys, explanations, and learning materials. Errors or omissions may occur, and we may correct or update content as issues are identified.

Scores, percentages, timers, and progress indicators describe performance on the relevant practice activity. They are not official examination results, academic records, or certificates and should not be treated as a guaranteed prediction of performance on an external examination.

Using Hard Math does not guarantee a particular score, grade, admission outcome, or improvement. Results depend on your preparation, prior knowledge, examination conditions, and other circumstances.

For current examination formats, registration rules, permitted tools, and scoring policies, consult the relevant examination organization. To report a possible error on Hard Math, email us with the page address and question or explanation concerned.

3. Examination names and independent status

References to examinations and educational programs identify the subjects or skills addressed by our materials. Hard Math practice activities are not official examinations administered by an examination board.

SAT® and AP® are registered trademarks of College Board. College Board is not affiliated with Hard Math and does not endorse this website.

Other third-party names, trademarks, and materials remain the property of their respective owners. Their appearance does not grant us ownership of them or imply a partnership or endorsement.

4. Acceptable use

You may use Hard Math for lawful learning, teaching, and reference purposes. You must not:

attempt to gain unauthorized access to the website, administrative areas, servers, or data;
upload or transmit malicious code, exploit vulnerabilities, or interfere with website security;
use automated tools in a way that overloads the website, bypasses access restrictions, or unlawfully copies protected content;
generate artificial advertising impressions or clicks, manipulate traffic measurements, or conduct fraudulent activity;
infringe another person’s intellectual property, privacy, or other legal rights;
misrepresent your identity, your relationship with Hard Math, or the source of our materials;
use the website to violate applicable examination or academic integrity rules.

We may take proportionate measures to investigate misuse and protect visitors and website systems, including limiting requests or restricting access where reasonably necessary.

5. Intellectual property and permitted use

Unless otherwise stated, original text, explanations, diagrams, graphics, branding, and other protected materials published by Hard Math belong to their respective authors or rights holders or are used under permission or license.

You may view our materials for personal study and use limited extracts of content that we are entitled to authorize for non-commercial teaching and classroom activities. Keep applicable ownership notices, identify Hard Math as the source where reasonably practicable, and do not present the material as your own original work.

Except where permitted by law or by the relevant rights holder, you must not reproduce or redistribute substantial portions of protected content, republish collections of our questions or explanations, sell copies, or use our branding to imply authorization or endorsement.

Separate notices or licenses may apply to third-party materials. This permission does not override those terms or give you rights that the relevant owner has not granted.

Nothing in these Terms restricts uses permitted by applicable copyright law. For other permissions or to report a rights concern, contact admin@hard-math.com and identify the relevant material.

6. Linking to Hard Math

You may link to publicly accessible Hard Math pages for lawful purposes. Links must accurately identify their destination and must not falsely suggest sponsorship, approval, or a relationship with Hard Math.

Do not display our pages or branding in a way that disguises their source or misleads visitors about who operates the content. We may request correction or removal of links or displays that infringe our rights or materially misrepresent the website.

7. Advertising

Hard Math uses Google AdSense technology to support advertising. Ads may be supplied by Google or advertising partners, depending on service availability, website settings, your location, and applicable privacy choices.

The presence of an advertisement does not mean that Hard Math endorses the advertiser, its claims, or its products or services. Advertisers are responsible for their own offers and promotional statements.

Any separate purchase or other transaction you enter into with an advertiser is governed by the relevant provider’s terms and applicable law. Review the offer and provider information before submitting information or making a purchase.

Advertising-related data processing and available choices are explained in our Privacy Policy.

8. External websites and services

Hard Math may link to independently operated websites or load third-party resources needed for functions such as mathematical rendering, page styling, analytics, or advertising.

Third-party websites and services have their own operators, terms, and privacy practices. We do not control their independent content or availability. A reference or link does not necessarily constitute a recommendation or endorsement.

These Terms govern your use of Hard Math and do not replace the terms that apply when you use an external service.

9. Privacy, cookies, and saved practice results

Our Privacy Policy explains the information processed through the website, including technical data, Google Analytics 4, Google AdSense, cookies, and email correspondence.

Some practice features save recent results in your browser using local storage. Such history is associated with that browser and device, may not be available on another device, and can be removed when you clear website data. Browser-saved results are provided for convenience and are not an official academic record.

Accepting these Terms or simply browsing the website does not, by itself, provide consent to non-essential cookies, tracking, or advertising personalization where separate consent is required. Applicable consent choices and other privacy controls are described in the Privacy Policy and any consent message presented during your visit.

10. Website availability and access

We aim to keep Hard Math accessible and working correctly. Access may be interrupted by maintenance, technical faults, network problems, security incidents, or circumstances beyond our reasonable control.

We may update, replace, or remove content or features for reasons such as correcting errors, improving the website, managing technical requirements, addressing security risks, or complying with applicable law.

Access may be restricted where reasonably necessary to prevent abuse or protect website operation. We will provide notice of relevant changes or restrictions where required by law; urgent security measures may need to take effect immediately.

11. Warranties and limitation of liability

Subject to rights that cannot lawfully be excluded, the website and its materials are provided on an “as is” and “as available” basis. We do not promise that access will always be uninterrupted, that every item will be free from errors, or that the materials will meet the requirements of every course or examination.

To the extent permitted by applicable law, Hard Math and its operator are not liable for indirect or consequential losses arising from use of the website, inability to access it, or reliance on its educational content. This may include loss of expected benefits or business opportunities where liability for that loss can lawfully be excluded.

These Terms do not exclude or limit liability for fraud, intentional misconduct, death or personal injury caused by negligence where such liability cannot be excluded, or any other liability that applicable law does not allow us to exclude or limit.

Nothing in this section removes mandatory warranties, remedies, consumer rights, or other legal protections available to you. Where a limitation is not permitted, the applicable legal rules govern our responsibility.

12. Applicable law and protected rights

These Terms apply subject to applicable law, including mandatory consumer and data protection rules. They do not require you to waive rights or protections that cannot legally be waived.

Any dispute may be brought before a court that has jurisdiction under the applicable legal rules. These Terms do not impose an exclusive court or remove any right to use a court or complaint procedure available to you under mandatory law.

If a provision is found unlawful or unenforceable, it will not apply to the extent of that finding. The remaining provisions continue to apply where they can lawfully operate independently of the affected provision.

13. Changes to these Terms

We may revise these Terms to reflect changes to website features, our operation, or applicable requirements. An updated version will be published on this page with a revised “Last updated” date.

Unless a later date is stated, revisions apply to subsequent use from publication, subject to any notice or agreement required by law. Continued use indicates acceptance only to the extent recognized by applicable law. Updates do not retrospectively remove rights that have already arisen.
