Privacy Policy — EchoBaby

Effective date: October 29, 2026

EchoBaby ("the app") is published by Nathaniel Anderson (AndersonsApps). EchoBaby turns two iPhones into a baby monitor and keeps a care log for your baby. This policy explains what the app does with your information. The short version: everything stays on your devices and in your own iCloud account. We run no servers, we never see your data, and we do not collect, sell, or share any of it.

What the app stores on your device

Everything you enter is saved in the app's local storage on your iPhone:

• Your baby's profile: name, birth date, an optional photo, and notes.
• Care logs: sleep, feedings, diapers, health notes and milestones, temperature, growth measurements, and medications.
• Your settings and care reminders.

This data never leaves your device through the app unless you turn on Family Sync or share an export (both described below). Deleting the app deletes it.

Baby monitor video and audio

When you use one iPhone as the baby unit and another as the parent device, live video and audio travel directly between those two phones over your own Wi-Fi network. The connection is encrypted using a key created when you pair the devices by QR code, and that key is kept in each phone's keychain. Nothing is sent to us or to any other server, and the monitor does not record. Noise, cry, motion, and position detection all run on the phones themselves.

Family Sync (optional)

If you turn on Family Sync, your baby's profile and care logs are stored in your private iCloud database and, if you invite caregivers, in an iCloud shared zone that only the people you invite can access. This uses Apple's iCloud (CloudKit) under Apple's privacy policy (https://www.apple.com/legal/privacy/). We have no access to it. You can turn Family Sync off at any time in Settings, remove caregivers from the share, and delete the stored data through iCloud settings on your device.

Exports

You can export your care log as a CSV file. The export is created on your device only when you ask for it and goes wherever you choose to share it.

Notifications

Alerts (noise, crying, movement, position) and care reminders are local notifications created on your phone. The app has no notification server of its own.

On-device intelligence

On iPhones that support Apple Intelligence, the app can summarize sleep patterns using Apple's on-device language model. The summary is generated on your phone; your logs are not sent anywhere to produce it.

Permissions the app asks for

• Camera and microphone: used only by the baby unit to stream live video and audio to the parent device.
• Local network: used to find your other phone on your Wi-Fi network.
• Notifications: used for alerts and reminders.
• Face ID or Touch ID: used only if you turn on App Lock, through Apple's authentication system. The app never sees your biometric data.

What the app does not do

• No analytics, advertising, or tracking SDKs. No third-party code of any kind.
• No accounts, sign-ups, or passwords.
• No servers of our own. The only online service the app can use is Apple's iCloud, and only if you turn on Family Sync.
• No access to contacts, location, or your photo library beyond the profile photo you choose.
• No data sold or shared with third parties.

Children

EchoBaby is made for parents and caregivers. The information about your baby is entered by you, belongs to you, and stays on your devices and in your iCloud account. The app is not directed at children and does not knowingly collect information from anyone under 13.

Changes

If this policy changes, the updated version will be posted at the same address with a new effective date.
