What we store
The calculator runs entirely in your browser. Your baby’s age or birth date, wake-up time, nap choice and any nap times you log are saved in your browser’s local storage so they’re there next time. They are never sent to us. You can remove them at any time by clearing this site’s data in your browser.
Accounts and analytics
There are no accounts. We don’t use our own analytics or tracking cookies.
Fonts
Fonts are loaded from Bunny Fonts, an EU-based service that does not log or store visitor IP addresses.
