Terms of Service

Last updated: June 5, 2026

The Basic Deal

By using Sleep Calculator, you're agreeing to these terms. If you don't agree, don't use it. Simple as that.

What You Can Do

This is a free tool for informational purposes. Use it for yourself, share it with friends, whatever. Just don't try to sell it or claim you built it. That'd be weird.

Medical Disclaimer

Look, this tool isn't medical advice. The calculations are based on general sleep science that works for most people, but everyone's different. If you have serious sleep issues, talk to a real doctor, not a website. This calculator helps with timing, not diagnosing sleep disorders.

Limitation of Liability

This tool is provided "as is" - no guarantees, no warranties. I'm not responsible if the calculator says to sleep at 10 PM and you still feel tired. There are a million factors that affect sleep quality. This is just one tool in your toolkit.

Changes to Terms

I might update these terms occasionally. If you keep using the site after I make changes, that means you're cool with the new terms. I won't make any crazy changes, this is just a sleep calculator.
