5. User Content

5.1 Your Content

  • You retain ownership of audio presets you create
  • By sharing presets to the community, you grant SINE a non-exclusive, worldwide license to display and distribute your preset within the App
  • You can remove shared presets at any time

5.2 Community Guidelines

When sharing presets, you agree not to:

  • Share content that is offensive, harmful, or inappropriate
  • Impersonate other users or misrepresent your identity
  • Spam or upload duplicate/low-quality content
  • Violate any applicable laws

5.3 Content Moderation

All shared presets are subject to admin review before becoming publicly visible. We reserve the right to reject or remove any content that violates these guidelines.

6. Health & Medical Disclaimer

SINE is a wellness tool and is not a medical device. The Bio-Resonance tracking feature provides general wellness information only.

6.1 No Medical Advice

  • SINE does not diagnose, treat, cure, or prevent any disease or medical condition
  • Nothing in the App, on the website, or in our content constitutes medical advice, diagnosis, or treatment recommendation
  • Heart rate and HRV data is for informational and wellness purposes only
  • Never disregard professional medical advice, diagnosis, or treatment because of information from SINE

6.2 Frequency & Sound-Related Claims

SINE provides access to binaural beats, solfeggio frequencies (including 174 Hz, 285 Hz, 396 Hz, 417 Hz, 432 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, and 963 Hz), brainwave entrainment, and ambient sounds. Within the App and in our content (blog articles, descriptions, info texts), certain properties are attributed to these frequencies and sound patterns, such as relaxation, focus, stress reduction, cellular regeneration, emotional release, improved sleep quality, or enhanced creativity.

These claims are based on historical traditions, subjective user experiences, and selected scientific research. They do not represent medically or scientifically established facts. Individual results may vary significantly, and there is no guarantee that any specific frequency or sound combination will produce a particular effect for you.

  • Descriptions such as "cellular regeneration", "DNA repair", "chakra balancing", or "healing frequency" reflect traditional or alternative concepts and are not to be understood as medical efficacy claims
  • The attribution of specific effects to certain frequencies (e.g., "528 Hz = transformation", "963 Hz = pineal gland activation") is based on cultural traditions and is not conclusively supported by scientific evidence
  • While individual studies suggest positive effects of binaural beats and certain frequencies on relaxation, focus, or sleep, the overall scientific evidence is mixed and requires further research
  • SINE encourages users to form their own experiences and draw their own conclusions rather than interpreting frequency descriptions as established facts

6.3 Bio-Resonance & Health Data

  • The Bio-Resonance feature displays heart rate and HRV data from Apple HealthKit and tracks trends over time
  • This data serves personal wellness information purposes and does not replace medical monitoring
  • Correlations between frequency usage and biosignals (e.g., "your HRV increased during the theta session") do not imply causation and do not constitute medical diagnosis

6.4 Safety Warnings

  • If you have a medical condition, epilepsy, or seizure disorder, consult a physician before using binaural beats
  • Do not use binaural beats while driving, operating machinery, or performing tasks that require full attention
  • If you experience dizziness, nausea, headaches, or discomfort during use, stop the session immediately
  • Binaural beats should only be used by children under 16 with parental supervision

6.5 Acknowledgment

By creating an account, subscribing, or using the App, you confirm that you have read and understood this Health & Medical Disclaimer. You acknowledge that all frequency- and sound-related descriptions within the App are exploratory in nature and do not promise guaranteed health outcomes.

7. Intellectual Property

  • SINE, its logo, design, and original content are owned by Divinebeingmetatron Ltd
  • The Sine Originals preset collection is proprietary content
  • Ambient sound recordings included in the App are licensed or original works
  • You may not copy, modify, distribute, or reverse-engineer any part of the App

These terms are governed by the laws of Cyprus. Disputes shall be resolved in the courts of Larnaca, Cyprus.

14. Apple App Store Terms

These Terms of Use constitute an agreement between you and Divinebeingmetatron Ltd only, and not with Apple Inc. ("Apple"). Divinebeingmetatron Ltd, not Apple, is solely responsible for the App and its content.

  • Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the App

15. Privacy Policy

Your use of SINE is also governed by our Privacy Policy, which can be found at sine-immersive.com/privacy. By using the App, you consent to the collection and use of your information as described in the Privacy Policy. The Privacy Policy is incorporated into these Terms by reference.

16. Severability

If any provision of these Terms is found to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect. The invalid or unenforceable provision shall be replaced by a valid and enforceable provision that most closely achieves the intended economic and legal purpose of the original provision.

17. Entire Agreement

These Terms of Use, together with the Privacy Policy, constitute the entire agreement between you and Divinebeingmetatron Ltd regarding the use of SINE and supersede all prior agreements, understandings, and communications, whether written or oral, relating to the subject matter hereof.

18. Force Majeure

Divinebeingmetatron Ltd shall not be liable for any failure or delay in performance resulting from causes beyond its reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, epidemics, pandemics, network infrastructure failures, strikes, or shortages of transportation, facilities, fuel, energy, labor, or materials.

19. Waiver

The failure of Divinebeingmetatron Ltd to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. Any waiver of any provision of these Terms will be effective only if in writing and signed by Divinebeingmetatron Ltd.
