4. Health and wellness disclaimer

LayOvr is a wellness tool, not a medical device. The circadian guidance provided by the App (sleep windows, light exposure timing, caffeine cutoffs, nap recommendations) is based on published chronobiological research and is intended for general informational purposes only.

LayOvr does not:

  • Provide medical advice, diagnosis, or treatment
  • Replace advice from a licensed healthcare provider
  • Guarantee specific outcomes (e.g., elimination of jet lag)
  • Account for individual medical conditions, medications, or contraindications

Consult your doctor before following the App's guidance if you have sleep disorders, circadian rhythm disorders, are pregnant or breastfeeding, take medication affecting sleep or alertness, or are a shift worker.

References to melatonin timing are informational. Melatonin's legal status and recommended dosage vary by country. Consult a pharmacist or physician before use.

5. HealthKit data

If you grant LayOvr access to Apple HealthKit, you confirm you are the authorized user of that health data. LayOvr reads health data only for the purpose described in our Privacy Policy. We do not upload health data externally.

6. Intellectual property

All content in the App, including but not limited to the circadian engine, UI design, graphics, text, and the LayOvr name and logo, is owned by Ceven Labs or its licensors and is protected by copyright and other intellectual property laws.

7. Disclaimer of warranties

The App is provided "as is" and "as available" without warranties of any kind, express or implied. To the maximum extent permitted by Danish and EU law, Ceven Labs disclaims all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement.

We do not warrant that the App will be uninterrupted, error-free, or that defects will be corrected.

8. Limitation of liability

To the maximum extent permitted by law, Ceven Labs shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the App, including but not limited to missed meetings, travel disruptions, or health outcomes.

Our total liability to you shall not exceed the amount you paid for the App in the 12 months preceding the claim.

9. Governing law and disputes

These Terms are governed by the laws of Denmark. Any dispute arising from these Terms shall be subject to the exclusive jurisdiction of the courts of Aarhus, Denmark, unless mandatory consumer protection laws in your country of residence require otherwise.

If you are a consumer within the EU, you also have the right to use the European Commission's Online Dispute Resolution platform: ec.europa.eu/consumers/odr

10. Changes to these Terms

We may update these Terms as the App evolves. We will notify you of material changes via the App or App Store release notes. Continued use after changes constitutes acceptance.
