Terms of Use
Effective and last updated: July 17, 2026
1. About this site
How Much Sleep Do I Need? provides general educational information and a browser-based planning calculator. In these terms, “the site” refers to howmuchsleepdoineed.com and “the operator” refers to How Much Sleep Do I Need?, the name under which this site is provided.
2. Not medical or safety advice
The site is not a medical service. It does not diagnose, treat, prevent, or monitor any condition, and its calculations are not personalized medical advice. Do not use a result to decide whether you are safe to drive, operate equipment, or perform safety-critical work. If you feel fatigued while driving, stop driving and pull over.
Seek a qualified healthcare professional for persistent sleep problems, excessive daytime sleepiness, loud snoring, breathing that stops and starts during sleep, gasping for air, or other health concerns. In an emergency, contact local emergency services.
3. Planning estimates
Results depend on the selections you enter and on editable assumptions such as time to fall asleep. Age-based ranges are population guidance. Individual sleep needs, sleep quality, medical conditions, schedules, and local clock changes can affect real outcomes. No result promises a particular level of alertness, health, or performance.
4. Acceptable use
You may use the site for lawful personal or informational purposes. You may not attempt to interfere with the service, bypass security controls, introduce malicious code, or use automated traffic in a way that materially disrupts availability for others.
5. Sources and changes
The site links to third-party and government sources for convenience and attribution. Those sources control their own content. Recommendations and product behavior may change when sources or the service are updated. The review date on the homepage identifies the latest recorded source review; it is not a claim of medical review.
6. Availability and warranties
The site is provided on an “as available” basis. To the extent permitted by applicable law, the operator disclaims implied warranties, including fitness for a particular purpose and non-infringement. The operator does not promise uninterrupted availability or error-free calculations.
7. Limitation of liability
To the extent permitted by applicable law, the operator is not liable for indirect, incidental, special, consequential, or punitive damages arising from use of or reliance on the site. Nothing in these terms excludes liability that cannot legally be excluded.
8. Changes to these terms
Updated terms may be posted at this URL with a revised date. Continued use after an update means the updated terms apply from their effective date.
9. Questions
The site does not publish an unverified contact address. A verified contact channel will be added here if one becomes available.
