PRIVACY POLICY
Mumble - Baby Tracker & Log
Last Updated: February 11, 2026
INTRODUCTION
This Privacy Policy describes how Mumble ("we", "our", or "the app") handles your information. Mumble is developed by an independent developer and is committed to protecting the privacy of its users and their families.
We built Mumble with privacy as a core principle. Your baby's data belongs to you and only you.
INFORMATION WE COLLECT
Mumble collects and stores the following types of data, all of which remain on your device and in your private iCloud account:
Baby Profile Information
- Baby's name, date of birth, gender, and profile photo
- This information is provided by you during setup and is used solely within the app to personalize your experience
Baby Care Logs
- Feeding entries (type, duration, volume, side)
- Sleep and nap entries (start time, end time, duration)
- Diaper change entries (type, time)
- Growth measurements (weight, length, head circumference)
- Health entries (temperature, medicine, doctor visits)
- Milestones and custom notes
- All log data is created by you and stored locally on your device
Voice Input Data
- Mumble uses Apple's on-device speech recognition to convert your voice input into text
- Voice audio is processed by Apple's Speech framework on your device
- The transcribed text is sent to an AI service (Anthropic Claude API) to parse your entry into structured data
- Only the transcribed text is sent, not the audio recording itself
- No voice recordings are stored or retained
Account Information
- If you sign in with Apple, we receive your Apple ID identifier and optionally your name and email address (depending on your choice during sign-in)
- This is used solely for authentication and iCloud sync
HOW YOUR DATA IS STORED
On Your Device
All baby care data is stored locally on your device using Apple's Core Data framework. This data never leaves your device except through iCloud sync (described below).
iCloud Sync
If you are signed in to iCloud, your data is synced across your devices using Apple's CloudKit. This means your data is stored in your private iCloud account, which is encrypted and managed by Apple. We do not have access to your iCloud data. For more information about iCloud security, visit Apple's iCloud security overview.
Shared Data (Family Sync)
If you invite caregivers to share your baby's timeline, the shared data is managed through Apple's CloudKit sharing. Only the people you explicitly invite can access the shared data. You can revoke access at any time.
HOW YOUR DATA IS USED
Your data is used exclusively to:
- Display your baby's care logs, growth charts, and insights within the app
- Provide smart insights and pattern analysis based on your logged data
- Generate pediatrician reports and data exports at your request
- Sync data across your devices via iCloud
- Share data with caregivers you explicitly invite
- Process voice input to create log entries
We do not use your data for advertising, analytics, profiling, or any purpose other than providing the app's functionality to you.
THIRD-PARTY SERVICES
Anthropic Claude API
Mumble uses the Anthropic Claude API to process transcribed voice input and to power the AI question feature. When you use voice input or ask a question, the text of your entry or question is sent to Anthropic's servers for processing. Anthropic's privacy policy applies to this data. No baby profile information, names, or identifying data is sent to Anthropic. For more information, visit Anthropic's privacy policy at https://www.anthropic.com/privacy.

- Apple Sign-In for authentication
- Apple Speech Recognition for on-device voice processing
- StoreKit for subscription management
- Apple Push Notifications for reminders
Apple's privacy policy applies to data handled by these services. Visit https://www.apple.com/privacy for details.

YOUR RIGHTS AND CHOICES
Data Export
You can export all of your data at any time from within the app in CSV, JSON, or PDF format.

CHILDREN'S PRIVACY

DATA SECURITY
We take reasonable measures to protect your data:
- All data is stored on your device and in your private iCloud account
- iCloud data is encrypted in transit and at rest by Apple
- We do not maintain our own servers or databases containing your data
