Privacy

Last updated 12 June 2026

The short version: we collect nothing. Everything you log stays in your private iCloud. We run no servers, we have no accounts, and we cannot see your data. This page exists to spell that out.

What we collect

Nothing. One Baby has no analytics, no telemetry, no crash-reporting SDKs, no advertising frameworks, and no third-party code that talks to anyone. There is no sign-up, so we never hold your name, email, or anything else.

Where your data lives

Feeds, diapers, sleep, growth, and your baby's profile are stored on your device and in your private iCloud database, managed by Apple's CloudKit. Apple syncs it between your devices using your iCloud account. That storage is governed by Apple's iCloud terms and Apple's privacy policy, not by any infrastructure of ours, because we have none.

Sharing with a partner

If you invite a caretaker, Apple shares your baby's records with that person through iCloud. Only people you explicitly invite can see them. You can stop sharing at any time from Settings, and their access ends.

Deleting your data

Settings → Delete all data removes everything from your device and from iCloud, including shared copies. Deleting the app alone removes it from your device but leaves the iCloud copy, so use Delete all data first if you want a clean break.

Children

One Baby is made for parents and caregivers, not for children. We do not knowingly collect information from anyone, of any age, because we do not collect information.

Changes

If this policy ever changes, the new version will be posted here with a new date. Given what the app is, do not expect much movement.
