Terms of Service

1. Acceptance of terms

These Terms of Service ("Terms") form a binding agreement between you and FightTech ("we", "us") regarding your use of the HackNao English application and related services (the "App"). By downloading, installing, or using the App, you confirm that you accept these Terms and our Privacy Policy. If you do not agree, do not use the App.

2. License to use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own non-commercial language-learning purposes. This license is also subject to the rules of the app store from which you obtained the App (the Apple App Store or Google Play).

3. Acceptable use

You agree not to:

• copy, modify, reverse-engineer, decompile, or create derivative works of the App, except as permitted by law;
• rent, sell, sublicense, or redistribute the App;
• use the App to infringe intellectual property rights or violate any law;
• attempt to disrupt or compromise the security or integrity of the App;
• use the App to upload, import, or share content you do not have the right to use.

4. Your content & imported material

The App lets you create recordings and import lesson packs (for example, teacher-shared shadowing or listening content). This material is stored on your device and remains yours. You are solely responsible for any content you record or import and for ensuring you have the rights to use it. We do not claim ownership of your recordings or imported files.

5. Third-party content & services

The App may display or stream content from third parties, including videos and audio served by YouTube / Google. Such content is provided by those third parties and is subject to their terms and policies. We do not control and are not responsible for third-party content, and its availability may change or be removed at any time.

6. Intellectual property

The App, including its software, design, text, graphics, and the HackNao English name and logo, is owned by FightTech or its licensors and is protected by intellectual property laws. Except for the license granted above, no rights are transferred to you.

7. Purchases & app stores

If the App offers paid features or subscriptions, those transactions are processed by the relevant app store (Apple or Google), and their payment, billing, and refund policies apply. Any pricing or availability of paid features may change. Your relationship with the app store for billing matters is governed by that store's terms.

8. Disclaimers

The App is provided "as is" and "as available" without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. Language-learning feedback, scores, and CEFR estimates are generated automatically and provided for guidance only; they are not a substitute for professional instruction or certified assessment, and we do not guarantee their accuracy or any specific learning outcome.

9. Limitation of liability

To the maximum extent permitted by law, FightTech will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of (or inability to use) the App. Our total liability for any claim relating to the App will not exceed the amount you paid for the App in the twelve months before the claim, or, where no amount was paid, a nominal sum.

10. Termination

You may stop using the App and uninstall it at any time. We may suspend or terminate your license if you materially breach these Terms. Provisions that by their nature should survive termination (e.g., intellectual property, disclaimers, limitation of liability) will continue to apply.

11. Governing law

These Terms are governed by the laws of the Socialist Republic of Vietnam, without regard to conflict-of-laws principles, unless a mandatory consumer-protection law in your country of residence requires otherwise. (Update this to the jurisdiction you operate from before publishing.)

12. Changes to these terms

We may revise these Terms from time to time. The "Last updated" date reflects the latest version. Material changes will be communicated through the App or store listing where appropriate. Continued use after changes take effect means you accept the revised Terms.
