Terms of Use

The license, safety responsibilities, product limitations, and legal framework for using RHz.

1. Agreement and scope

These Terms govern access to and use of the RHz Android application, the RHz website, and related materials operated by Logic & Light. By downloading, accessing, or using RHz, you agree to these Terms. If you do not agree, do not use the app or website.

2. Eligibility

You must be legally capable of entering this agreement in your jurisdiction, or use RHz under the supervision and authorization of a parent or legal guardian who accepts these Terms on your behalf.

3. Wellness use only

RHz is offered for general wellness, breathing practice, education, and personal experimentation. It is not intended to diagnose, monitor, treat, cure, or prevent a disease or medical condition and is not a substitute for professional medical advice, diagnosis, or treatment.

Do not use RHz for emergency decisions. If you think you are having a medical emergency, seek immediate medical care.

4. Safety responsibilities

Use RHz only in a safe environment. Do not use the app while driving, cycling, operating machinery, supervising safety-critical tasks, or in any situation where reduced attention could create risk.

Stop immediately if you experience dizziness, faintness, chest pain, severe shortness of breath, unusual palpitations, or another concerning symptom. If you have a clinically managed condition, consult a qualified healthcare professional before use.

5. Hardware, data, and output limitations

RHz depends on third-party hardware, operating systems, Bluetooth behavior, and sensor data quality. Compatibility is not guaranteed with every monitor or device. Measurements, scores, trends, resonance outputs, and pacing adjustments may be affected by motion, signal noise, hardware limits, environmental conditions, software bugs, or setup.

Do not rely on RHz output as clinical, diagnostic, safety-critical, or guaranteed-accurate information.

6. License

Subject to these Terms, Logic & Light grants you a limited, personal, non-exclusive, non-transferable, revocable license to use RHz for lawful personal use.

You may not:

  • copy, resell, rent, sublicense, or distribute RHz except where permitted by law;
  • reverse engineer or attempt to extract source code except where local law grants that right;
  • interfere with the app, website, or related systems; or
  • use RHz in a way that violates law or another person's rights.

7. Exports and third-party sharing

RHz may let you export session data. Export is initiated by you. Once exported or shared outside the app, the data may no longer be protected by RHz's local-storage design and may be handled by other apps, services, or people under their own terms and privacy practices.

8. Website and communications

The website may include guides, product information, analytics, and support communications. These features are governed by these Terms and the Privacy Policy.

9. Intellectual property

RHz, its branding, site content, app content, and related materials are owned by Logic & Light or its licensors and are protected by applicable intellectual-property laws. These Terms grant a right to use RHz, not ownership.

10. Disclaimer of warranties

To the maximum extent permitted by law, RHz is provided on an “as is” and “as available” basis without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, availability, or uninterrupted operation.

11. Limitation of liability

To the maximum extent permitted by law, Logic & Light and its affiliates, contractors, and licensors will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, goodwill, data, or business interruption arising from use of RHz.

To the maximum extent permitted by law, the total aggregate liability of Logic & Light arising from RHz or these Terms will not exceed the greater of the amount paid for RHz in the 12 months before the event giving rise to the claim or CAD $50.

12. Mandatory consumer rights

Nothing in these Terms excludes, restricts, or waives rights that cannot be excluded under laws that apply to you, including mandatory consumer-protection, privacy, product-liability, or digital-content rights.

13. Governing law and disputes

Except where mandatory local law requires otherwise, these Terms are governed by the laws of Ontario and the federal laws of Canada applicable there. Except where local law grants a different right, courts located in Ontario, Canada will have exclusive jurisdiction over disputes related to RHz or these Terms.

14. Changes

These Terms may be updated to reflect legal, product, or operational changes. The current version will be posted on this page. Continued use after changes take effect means you accept the updated Terms unless applicable law requires another form of notice or consent.
