Terms of Service

Last updated: August 17, 2026

Please read these terms before using Math Problems Vault("the site").

1. What this site is

Math Problems Vaultis a personal, non-commercial educational project. It collects practice problems drawn from published mathematics textbooks — each one credited in full next to the problem and in the References section of any page that uses it — together with hints, remarks, and solutions written by the site's maintainer. The site is intended for personal study, teaching preparation, and educational reference, not for commercial resale or redistribution.

2. Content and copyright

• Problem statements are drawn from the textbooks credited in each problem's citation. All rights to the original works remain with their respective authors and publishers.
• Hints, remarks, and worked solutions displayed publicly on this site are the original work of the site's maintainer — not reproductions of any publisher's official solutions manual.
• This site is provided for individual, non-commercial educational use only. You may not scrape, republish, or redistribute its contents for commercial purposes.
• If you are a rights holder and believe content on this site infringes your copyright, please contact admin@mathprobvault.com with the specific page(s) in question. We will review the request in good faith and act promptly, including removing the content while the matter is resolved if appropriate.

3. No warranty

The site and its content are provided "as is", without warranty of any kind. We make no guarantee that problem statements, solutions, or any other content are complete, error-free, or fit for any particular purpose. Solutions are provided for educational reference only — always verify independently before relying on them (e.g. for grading or publication).

4. Accounts

If the site offers optional accounts or subscriptions, you're responsible for keeping your login credentials secure and for all activity under your account.

5. Limitation of liability

To the fullest extent permitted by law, the site's maintainer is not liable for any damages arising from your use of the site or reliance on its content.

6. Changes

These terms may be updated from time to time; continued use of the site after a change means you accept the updated terms.
