Terms of Service

Effective date: April 20, 2026

Last updated: April 20, 2026

These Terms of Service ("Terms") govern your access to and use of the Hmonglus mobile application, website, and related services (collectively, the "Service") provided by CharlieTech ("we", "us", or "our"). Please read these Terms carefully before using the Service.

By downloading, installing, accessing, or using the Service, you agree to be bound by these Terms and our Privacy Policy. If you do not agree, do not use the Service.

1. Eligibility

The Service is intended for users of all ages who want to learn the Hmong language. If you are under the age of 13 (or the minimum age required in your country), you may only use the Service with the permission and supervision of a parent or legal guardian who agrees to these Terms on your behalf.

By using the Service, you represent that you have the legal capacity to enter into these Terms, or that your parent or guardian has accepted these Terms on your behalf.

2. Description of the Service

Hmonglus is an educational application that provides language-learning content, including flashcards, lessons, quizzes, games, and related features. We may add, modify, or remove features at any time. We do not guarantee that any particular content, topic, or feature will remain available.

3. License and Acceptable Use

3.1 Limited License

Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to access and use the Service for your own non-commercial learning purposes.

3.2 Restrictions

You agree not to:

• Copy, modify, distribute, sell, lease, or sublicense any part of the Service or its content;
• Reverse engineer, decompile, or attempt to extract the source code of the App, except where permitted by law;
• Use the Service for any unlawful purpose or in violation of any applicable law;
• Interfere with or disrupt the Service, servers, or networks connected to the Service;
• Use automated means (bots, scrapers, etc.) to access the Service without our written permission;
• Impersonate any person or entity, or misrepresent your affiliation with any person or entity;
• Upload or transmit viruses, malware, or other harmful code; or
• Attempt to gain unauthorized access to any portion of the Service or related systems.

4. Accounts

The Service may be used without creating an account. If we offer optional account features in the future, you are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us promptly at [email protected] if you believe your account has been compromised.

5. Intellectual Property

The Service, including all text, graphics, logos, icons, images, audio, software, and other materials, is owned by CharlieTech or its licensors and is protected by copyright, trademark, and other intellectual property laws. Except for the limited license granted in Section 3, no rights are transferred to you.

"Hmonglus" and related branding are trademarks of CharlieTech. You may not use our trademarks without our prior written consent.

6. User Content and Feedback

If you submit feedback, suggestions, or other communications to us, you grant us a non-exclusive, worldwide, royalty-free, perpetual license to use, modify, and incorporate that feedback into the Service without obligation to compensate you.

The Service does not currently allow users to post public user-generated content. If we add such features, additional terms may apply.

7. Third-Party Services and Links

The Service may link to or integrate with third-party services (such as app stores, analytics providers, or social media platforms). We are not responsible for third-party services, and your use of them is subject to their own terms and policies. See our Privacy Policy for how third parties may process data.

8. Purchases and Subscriptions

If the Service offers in-app purchases or subscriptions, those transactions are processed by the applicable app store (Google Play or Apple App Store). Payment, billing, refunds, and cancellations are governed by the app store's terms and policies. We do not control app store billing and cannot issue refunds except as required by law or as described in the app store's policies.

9. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the Service will be uninterrupted, error-free, secure, or that learning outcomes or proficiency in Hmong will result from use of the App. Educational content is provided for general learning purposes and may contain inaccuracies; we welcome corrections via [email protected].

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CHARLIETECH AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE.

OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) FIFTY U.S. DOLLARS ($50 USD).

Some jurisdictions do not allow certain limitations of liability, so some of the above limitations may not apply to you.

11. Indemnification

You agree to indemnify and hold harmless CharlieTech and its affiliates from any claims, damages, losses, and expenses (including reasonable attorneys' fees) arising from your misuse of the Service or violation of these Terms.

12. Termination

We may suspend or terminate your access to the Service at any time, with or without notice, if we believe you have violated these Terms or if we discontinue the Service. You may stop using the Service at any time by uninstalling the App.

Sections that by their nature should survive termination (including intellectual property, disclaimers, limitation of liability, and governing law) will survive.

13. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date at the top of this page and, where appropriate, provide additional notice within the App or by other reasonable means. Your continued use of the Service after changes become effective constitutes acceptance of the revised Terms.

14. Governing Law and Disputes

These Terms are governed by the laws of the United States and the State in which CharlieTech operates, without regard to conflict-of-law principles. Any dispute arising from these Terms or the Service will be resolved in the courts located in that jurisdiction, unless applicable law requires otherwise.

If you are a consumer in the European Union or another jurisdiction with mandatory consumer protection laws, you may have additional rights that cannot be waived by these Terms.

15. App Store Terms

If you downloaded the App from the Apple App Store or Google Play Store, you also agree to the applicable store's terms. Apple and Google are not parties to these Terms and are not responsible for the Service. Apple and its subsidiaries are third-party beneficiaries of these Terms if you obtained the App through the Apple App Store.
