Privacy Policy

Our Commitment to Privacy

At Sleep-Calculator.app, we believe in complete privacy. Our service is designed to work without collecting any of your personal data.

We Do Not Collect Any Data

• ✓ No Account Required — You can use our sleep calculator without signing up or logging in.
• ✓ No Personal Information — We don't ask for your name, email, or any other personal details.
• ✓ No Data Transmission — The times you enter are processed entirely in your browser. Nothing is sent to our servers.

How Our Calculator Works

When you use our sleep calculator, all calculations happen locally in your web browser using JavaScript. The wake-up times or bedtimes you enter never leave your device. When you close the page, all data is gone — we have no way to access or store it.

External Links

Our website may contain links to external resources. We are not responsible for the privacy practices of other websites. We encourage you to review their privacy policies when visiting external sites.

Changes to This Policy

If we ever change our privacy practices, we will update this page. However, our core principle remains the same: your privacy is respected, and we do not collect your data.
