Use of the site

You may use the public site for personal, non-commercial purposes. Do not attempt to interfere with the site, misuse automated access, probe for vulnerabilities, or use the service in a way that degrades the experience for other visitors.

Informational sleep guidance

The calculator and sleep articles are provided for general education and routine planning. The 90-minute sleep cycle model is a useful estimate, not a measurement of your actual sleep stages. Results can vary by person, schedule, age, health, caffeine, medication, stress, and environment.

Bedtime Calculator is not medical advice and is not a substitute for professional diagnosis, treatment, or emergency care. Do not rely on the site for clinical decisions. If sleep problems are persistent, severe, or connected to a health concern, consult a qualified medical professional.

No warranty

We aim for accurate calculations, but the service is provided on an as-is basis without warranties of availability, fitness for a particular purpose, or uninterrupted access.

Content and external links

The sleep tips blog may include educational content or links to other resources. External sites are controlled by their own owners, and Bedtime Calculator is not responsible for their content, policies, or availability.

Privacy

The current calculator is designed to run in the browser without accounts or saved sleep history. Review the privacy policy for more detail about calculator inputs, analytics, cookies, and future advertising changes.

Changes

These terms may be revised as the product evolves. Material changes will be reflected on this page. You can return to the bedtime calculator at any time.
