Terms of Service for Meridian

Last Updated: July 2, 2026

These Terms of Service ("Terms") are a legal agreement between you ("you" or "User") and NGNN Studio ("we," "our," "us," or "Licensor") governing your use of the Meridian: Posture & Health macOS application, including any updates, related documentation, and services made available within it (collectively, the "App").

By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not download, install, or use the App.

1. Eligibility

You must be at least 13 years old to use the App. If you are under the age of majority in your jurisdiction, you may only use the App with the involvement and consent of a parent or legal guardian. By using the App, you represent that you meet these requirements.

2. License Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App for your personal, non-commercial use on any Apple-branded device that you own or control, as permitted by the Usage Rules set forth in the App Store Terms of Service.

All rights not expressly granted to you are reserved by us and our licensors. You may not copy, modify, distribute, sell, lease, reverse-engineer, decompile, or create derivative works based on the App, except to the extent such restriction is prohibited by applicable law.

3. Health & Medical Disclaimer

The App is not a medical device and does not provide medical advice, diagnosis, or treatment.

Meridian provides general wellness reminders and posture-related feedback (including optional AirPods motion-based posture detection) for informational and self-improvement purposes only. It is not intended to diagnose, treat, cure, or prevent any disease, injury, or medical condition, and it is not a substitute for professional medical advice, examination, diagnosis, or treatment.

  • Posture, hydration, stretch, and other reminders are general wellness suggestions, not personalized medical guidance.
  • AirPods-based motion detection is an approximate, consumer-grade estimate and may be inaccurate, delayed, or unavailable depending on hardware, connectivity, and calibration.
  • Always consult a qualified physician or other licensed healthcare provider before making changes to your health, ergonomic, or physical activity habits, and before disregarding or delaying professional medical advice because of anything experienced through the App.
  • If you believe you are experiencing a medical emergency, contact emergency services immediately. Do not rely on the App in any emergency situation.

Your use of any health, posture, or wellness feature of the App is entirely at your own risk.

4. In-App Purchases - Meridian Zenith

The App offers an optional one-time, non-consumable in-app purchase ("Meridian Zenith") that unlocks additional features. All purchases are processed exclusively by Apple through the App Store and are subject to Apple's own terms and payment policies, including its refund policies.

We do not process, store, or have access to your payment card details or Apple ID credentials. Purchases are final except where a refund is granted by Apple in accordance with Apple's policies. We have no obligation to issue refunds directly.

5. Feedback and Diagnostic Submissions

If you voluntarily submit feedback, bug reports, or "Report a Problem" diagnostics through the App, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use, reproduce, and act on that submission (including any suggestions or ideas it contains) for any purpose, without obligation or compensation to you. Do not submit anything you do not have the right to share, or that contains sensitive personal or medical information you do not wish us to receive.

Our collection and handling of diagnostic and feedback data is further described in our Privacy Policy.

6. Acceptable Use

You agree not to:

  • Use the App for any unlawful purpose or in violation of any applicable local, state, national, or international law or regulation;
  • Attempt to gain unauthorized access to any systems or networks connected to the App;
  • Interfere with or disrupt the integrity or performance of the App;
  • Use the App to develop a competing product or service;
  • Remove, obscure, or alter any proprietary notices in the App.

We reserve the right to suspend or terminate your access to the App if we reasonably believe you have violated these Terms.

7. Intellectual Property

The App, including its source code, design, graphics, logos, wordmarks, and all associated content, is owned by NGNN Studio or its licensors and is protected by copyright, trademark, and other intellectual property laws. Nothing in these Terms transfers any ownership rights to you.

8. Disclaimer of Warranties

The App is provided "as is" and "as available," without warranty of any kind, whether express, implied, or statutory, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of course of dealing or usage of trade.

We do not warrant that the App will be uninterrupted, error-free, secure, or free of harmful components, or that any defects will be corrected. You use the App at your own risk.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you.

9. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall NGNN Studio, its officers, employees, or agents be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, data, goodwill, or other intangible losses, arising out of or related to your use of, or inability to use, the App - including any health, posture, or wellness-related reliance - whether based on warranty, contract, tort (including negligence), or any other legal theory, even if we have been advised of the possibility of such damages.

To the maximum extent permitted by applicable law, our total cumulative liability to you for all claims arising out of or relating to the App or these Terms shall not exceed the greater of (a) the amount you paid us in the twelve (12) months preceding the claim, or (b) ten U.S. dollars (US $10).

Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so some of the above limitations may not apply to you.

10. Indemnification

You agree to indemnify, defend, and hold harmless NGNN Studio and its officers, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in any way connected with your use of the App, your violation of these Terms, or your violation of any rights of a third party.

11. Termination

We may suspend or terminate your access to the App at any time, with or without cause or notice, including if we believe you have violated these Terms. You may stop using the App and delete it at any time. Sections of these Terms that by their nature should survive termination (including Sections 3, 5, 7–10, and 12–16) will survive.

12. Changes to the App and These Terms

We may modify, suspend, or discontinue the App, or any feature of it, at any time without liability to you. We may also revise these Terms from time to time. Material changes will be reflected by updating the "Last Updated" date above. Your continued use of the App after changes take effect constitutes acceptance of the revised Terms.

13. Export Compliance and Legal Compliance

You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties. You agree to comply with all applicable export and re-export control laws and regulations.

14. Governing Law and Dispute Resolution

These Terms are governed by the laws of the United States and the State of Delaware, without regard to conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the App shall be resolved exclusively in the state or federal courts located in Delaware, and you consent to the personal jurisdiction of such courts. This does not deprive you of any consumer protection rights you may have under the mandatory laws of your country of residence.

15. Apple-Specific Terms

Because the App is distributed via the Apple App Store, the following additional terms apply and take precedence over any conflicting term in these Terms:

  • Acknowledgment. These Terms are between you and NGNN Studio only, not with Apple Inc. ("Apple"). Apple is not responsible for the App or its content.
  • Scope of License. The license granted to you is limited to a non-transferable license to use the App on any Apple-branded device that you own or control, as permitted by the App Store's Usage Rules.
  • Maintenance and Support. We, not Apple, are solely responsible for providing any maintenance and support for the App. Apple has no obligation whatsoever to furnish any maintenance or support services.
  • Warranty. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to a warranty are our sole responsibility.
  • Product Claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the App, including product liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
  • Intellectual Property. In the event of any third-party claim that the App or your possession and use of the App infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement, and discharge of any such claim.
  • Legal Compliance. You represent that you are not located in a country subject to a U.S. Government embargo or listed as a "terrorist supporting" country, and are not listed on any U.S. Government list of prohibited or restricted parties (see Section 13 above).
  • Third-Party Beneficiary. You acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

16. Miscellaneous

  • Entire Agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede any prior agreements.
  • Severability. If any provision of these Terms is held unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force.
  • No Waiver. Our failure to enforce any right or provision of these Terms will not be considered a waiver of that right or provision.
  • Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms without restriction.
