Terms of Use

Agreement to these terms

SleepTools.co ("SleepTools", "we", "us") is a free collection of sleep calculators and educational articles. By using the site you agree to these terms. If you do not agree with them, please do not use the site. Because everything here is free and requires no account, these terms are deliberately short and plain.

Not medical advice

All calculators, results, articles, and other content on SleepTools are educational information only. They are not medical advice, diagnosis, or treatment, and they are not a recommendation to take, stop, or change any supplement or medication. Using this site does not create a doctor-patient or any other professional relationship between you and us.

Calculator results are estimates based on averaged, published research. Individual physiology varies, and no output here accounts for your medical history, medications, or health conditions. Always consult a qualified healthcare provider before acting on anything you read here, especially regarding sleep disorders, supplements such as melatonin, alcohol, children's or teenagers' sleep, or safety-critical work. Never disregard professional medical advice, or delay seeking it, because of something you read on this site.

No warranties

The site is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of accuracy, completeness, fitness for a particular purpose, or uninterrupted availability. We work to keep the content accurate and cite our sources on the Methodology and Data sources pages, but sleep science evolves and errors are possible. We may change, suspend, or remove any part of the site at any time.

Limitation of liability

To the fullest extent permitted by law, SleepTools and its operator are not liable for any direct, indirect, incidental, consequential, or special damages arising from your use of, or reliance on, the site or its content. This includes, without limitation, health outcomes, missed sleep, lost productivity, or decisions made based on calculator results. Your sole remedy for dissatisfaction with the site is to stop using it. Nothing in these terms excludes liability that cannot be excluded under applicable law.

Acceptable use

You agree not to misuse the site: no attempting to disrupt or overload it, no probing for vulnerabilities, and no using automated tools to scrape the site in a way that degrades service for others. You may link to any page freely.

Intellectual property

The site's content, design, and code are owned by the site operator unless otherwise noted. You may use the calculators and quote reasonable excerpts of the content for personal, educational, or journalistic purposes with attribution and a link. Republishing substantial portions of the content, or presenting it as your own, is not permitted. The research papers and guidelines we cite belong to their respective authors and publishers.

Children and teenagers

SleepTools does not require accounts and does not knowingly collect personal information from anyone, including children. Tools that concern babies and teenagers are written for parents and caregivers. If you are under 18, involve a parent, guardian, or healthcare provider before acting on anything here, and do not use any supplement without their guidance.

Third-party services

The site uses third-party services (such as Google Analytics, Google AdSense, Formspree, and Vercel) described in our Privacy Policy and Cookie Policy. We also link to external research and resources. We are not responsible for the content or practices of third-party sites and services.

Changes to these terms

We may update these terms from time to time. The date at the top of this page will always show when they were last changed. Continuing to use the site after a change means you accept the updated terms.

Governing law

These terms and any dispute arising from them are governed by the laws that apply in the site operator's place of residence, without regard to conflict-of-law rules, except where the law of your own country grants you protections that cannot be waived.
