Terms & Conditions

Welcome to CalcSleepTimer

Hey, glad you are here. CalcSleepTimer was built for one reason — to help people stop waking up feeling terrible. No complicated setup, no account, no cost. Just a simple tool that works with your body’s natural sleep rhythm instead of against it. Before you dive in, take two minutes to read through these terms. They are straightforward and written like a human actually wrote them — because one did.

What CalcSleepTimer Is

A free sleep cycle calculator. You put in a time, it gives you better sleep and wake options based on 90-minute sleep cycles. That is the whole product. No subscriptions, no hidden fees, no accounts required.

What It Is Not

It is not medical advice. It is not a diagnostic tool. It is not a replacement for a doctor. If you have real sleep problems — insomnia, sleep apnea, anything chronic — please see a healthcare professional. A calculator cannot fix that and we will never claim it can.

Use It Responsibly

CalcSleepTimer is for personal, non-commercial use. Do not copy the site, scrape the content, or try to pass it off as your own. The content, design, and calculator logic belong to us.

No Guarantees

We built this tool carefully and it is based on real sleep science. But we cannot guarantee it works perfectly for every single person in every single situation. Sleep is personal. Results may vary. Use the calculator as a helpful guide — not a rigid rule.

We Are Not Liable

If you follow the calculator’s suggestions and something does not work out the way you hoped, that is on you. We provide the tool in good faith. We are not responsible for decisions you make based on it.

This includes but is not limited to:

  • Missing work or appointments due to sleep timing
  • Any health outcomes related to sleep changes
  • Any reliance on this tool in place of medical advice

Third Party Links


If we link to any external sites, we are not responsible for their content or privacy practices. Those sites have their own rules.

Changes to These Terms

We may update these terms occasionally. When we do, the date at the top changes. Continued use of the site means you accept the updated terms.

Governing Law

These terms are governed by the laws of USA and CANADA. Any disputes will be handled accordingly.
