Terms of use

Last updated 12 June 2026

One Baby is a free app for tracking your baby's feeds, diapers, sleep, and growth, and for keeping the next feed visible without opening anything. Using it means you agree to the terms below.

It is not medical advice

One Baby is a tracking aid, not a medical device. Countdowns are based on what you log, and they are suggestions, not instructions. For anything concerning your baby's health or feeding, trust your own judgment and your pediatrician over a number on a screen.

The license

One Baby is distributed through the Apple App Store and licensed to you, not sold, under Apple's standard Licensed Application End User License Agreement. You get a personal, non-transferable license to use the app on Apple devices you own or control.

What the app needs

iOS 18 or later, watchOS 11 or later for the watch app, and an iCloud account. Sync and sharing run on Apple's iCloud, so their availability is in Apple's hands, not ours.

Your data

Your data is yours and stays in your iCloud. We collect nothing. The details live in the privacy policy.

No warranties

The app is provided as is, free of charge, without warranties of any kind. To the extent the law allows, we are not liable for losses arising from your use of the app, including missed or inaccurate countdowns. The app helps you keep track; responsibility for your baby's care stays with you.

Changes

These terms may change as the app does. The current version always lives here, with the date above.
