Terms of Service

Last updated: September 1, 2026

1. Acceptance of terms

Accessing or using memoryduel.com (hereinafter "this site") means you agree to these Terms. If you disagree, please don't use this site.

2. Service description

MemoryDuel is a browser-based general-knowledge battle platform offering online battles, AI sparring, and memory training. The site is provided "as is" and "as available" without any express or implied warranties, including merchantability, fitness for a particular purpose, or non-infringement.

3. Disclaimer

We do not guarantee:

• The service will be uninterrupted, error-free, or always secure
• Any bug, defect, or error will be fixed within a specific time
• The service is free of viruses, malware, or harmful components (you are responsible for your own device security)
• Results obtained via this site will meet your specific needs

4. Limitation of liability

To the maximum extent permitted by law, this site, its operators, contributors, or affiliates are not liable for any indirect, incidental, special, consequential, or punitive damages (including lost time, data loss, lost profits, or emotional distress), even if told of the possibility.

5. Intellectual property

• Source code: all original code is released under CC-BY 4.0.
• Question content: questions in our bank are original; commercial use without permission is prohibited.
• Trademark: "MemoryDuel" and the site logo are the operator's trademarks; use without written permission is prohibited.
• Your submissions: if you send feedback, suggestions, or questions, you grant us an unlimited, free, perpetual license to use them.

6. User conduct

You agree not to:

• Beyond normal browser use, attempt to crawl, scrape, or systematically extract this site's data
• Use automated tools (crawlers, headless browsers) to overload this site or bypass reasonable rate limits
• Reverse-engineer, decompile, or extract source code beyond what is already public
• Use this site for any illegal purpose or in violation of applicable law
• Use cheats, hacks, or any means that undermine fair play in battles

7. Service changes & termination

We may modify, suspend, or terminate the service at any time without notice. Since this site has no accounts and stores no personal data, termination only means the site may go offline — your local data stays in your browser.

8. Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region of China. If your jurisdiction has mandatory consumer-protection laws (e.g. EU, California), those mandatory protections prevail to the extent applicable.

9. Changes to terms

We may revise these terms at any time. The "Last updated" date reflects the latest revision. Continued use after changes means you accept the new terms.

10. Contact

For questions about these terms, email [email protected] with [Terms] in the subject. We'll reply within 3 business days.
