Terms of Use

01Acceptance of These Terms

These Terms of Use apply to circadianhub.com (the "Site", "CircadianHub", "we"). By using the Site you agree to them. If you do not agree, please do not use the Site. Our Privacy Policy explains how data and cookies are handled and forms part of how the Site operates.

02What the Site Offers

CircadianHub provides free sleep-planning calculators (bedtime, wake-up time, nap, shift worker and jet lag tools) and educational articles about sleep and the body clock. The tools work from general rules, such as an average sleep cycle of about 90 minutes, so their results are estimates and not measurements of your own sleep.

03Not Medical Advice

Everything on the Site is for general information and education only. It is not medical advice, diagnosis or treatment, and it does not create a doctor-patient relationship. Do not use the Site to decide on medication, to manage a medical condition, or to judge whether you are fit to drive or to operate machinery. If you have ongoing sleep problems, severe daytime sleepiness or any health concern, speak with a doctor or another qualified health professional. If you think you may be having a medical emergency, contact your local emergency services.

04Using the Site

You may use the Site for your own personal, non-commercial purposes. You agree not to:

• use the Site in a way that is unlawful or that harms other people;
• attempt to disrupt, overload or gain unauthorised access to the Site or its hosting;
• use automated tools to copy the Site at scale, or to resell or republish its content;
• misrepresent your relationship with CircadianHub.

05Accuracy and Availability

We try to keep the Site accurate and up to date, but we make no promise that it is free of errors or that it will always be available. Calculator results, schedules and article content are provided "as is". Sleep needs and body clocks differ from person to person, and research changes over time, so treat what you find here as a starting point and adjust it to how you feel.

06Intellectual Property

The text, design, images and code of the Site belong to CircadianHub or its licensors and are protected by copyright. You may quote short extracts with a clear link back to the original page. Please do not copy, republish or sell larger parts of the Site without our written permission.

07Advertising and Third-Party Links

The Site may show advertisements, including through Google AdSense, and may link to other websites such as scientific or health organisations. We do not control those sites and are not responsible for their content or policies. Advertisements are not endorsements, and nothing advertised on the Site is recommended by us. Details of how advertising cookies work, and how to change your choices, are in the Privacy Policy.

08Limitation of Liability

To the fullest extent permitted by law, CircadianHub and its owners are not liable for any loss or damage arising from your use of, or reliance on, the Site, including decisions about sleep, work, travel or health made using its tools or articles. Nothing in these terms limits any right you have as a consumer, or any liability that cannot be excluded by law.

09Changes to These Terms

We may update these terms from time to time. The date at the top shows when they last changed. Continuing to use the Site after a change means you accept the updated terms.
