Privacy policy

Short version: all calculations run locally in your browser. The times you enter are never sent to, or stored on, our servers.

What we collect

Nothing personal. There are no accounts, no forms, and no cookies used for advertising. Like most websites, our hosting provider may process basic technical logs (such as IP address and user agent) for security and reliability purposes.

What stays on your device

The wake-up times, bedtimes, and nap times you enter are processed by client-side code and are not transmitted anywhere. Closing the tab erases them.

Third-party services

We keep third-party services to a minimum. If we ever add analytics or embedded content, this page will be updated before that change goes live.
