No guarantees

Calculations are estimates based on common sleep-cycle assumptions (for example, roughly 90-minute cycles). Individual sleep architecture varies. We do not guarantee sleep quality, health outcomes, accuracy for your situation, or uninterrupted availability of the Site.

Limitation of liability

To the fullest extent permitted by law, the Site and its operators are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of or reliance on the Site. Your sole remedy for dissatisfaction with the Site is to stop using it.

You may not copy, scrape, or redistribute substantial portions of the Site without prior written consent, except where allowed by law.

Third-party services

The Site may load scripts or content from third parties (for example, analytics or advertising). Those services have their own terms and privacy practices. See our Privacy Policy for more detail.

Acceptable use

You agree not to misuse, interfere with, or attempt to disrupt the Site, its services, or connected infrastructure. You agree not to use automated means to access the Site in a way that imposes an unreasonable load or bypasses normal use.

Changes

We may update these terms at any time. The “Last updated” date will change when we do. Continued use of the Site after changes means you accept the latest version.
