Data Storage & Security

Local Storage

All your data is stored locally on your device in an encrypted database.

iCloud Sync

If you enable iCloud sync:

• Your data is synced to your personal iCloud account
• Data is encrypted in transit and at rest
• We cannot access your iCloud data
• Apple's iCloud terms and privacy policy apply

Family Sharing

If you share access with family members:

• Only family members in your iCloud Family Sharing group can be invited
• Shared data is transmitted via Apple's CloudKit sharing infrastructure
• You can revoke access at any time

Data Retention

• Your data remains on your device until you delete it
• If you delete the App, local data is removed
• iCloud data can be managed through your iCloud settings
• You can export your data as CSV at any time from the App

Children's Privacy

Cradl is designed for parents and caregivers to track infant care. The App does not collect personal information from children. All data entered is provided by adult users about their infants.

Third-Party Services

Apple Services

Cradl uses the following Apple services:

• iCloud/CloudKit: For data sync (governed by Apple's privacy policy)
• StoreKit: For subscription management (governed by Apple's privacy policy)
• Siri/App Intents: For voice commands (processed on-device)

AI Features

The App includes optional AI-powered insights provided through OpenAI, L.L.C. ("OpenAI"):

• We ask for your permission in the app before AI features send data to OpenAI
• When AI features are enabled, we send the data needed to generate summaries and insights, which may include baby profile details, logged events (feeding, sleep, diaper, medication, and growth), notes, and related timestamps
• You can disable AI features at any time in app Settings to stop future sharing for AI summaries
• We require third-party providers that process data on our behalf to provide protections that are the same as or stronger than those described in this policy
• OpenAI's privacy policy is available at: https://openai.com/policies/privacy-policy

You have the right to:

• Access your data (via the App or CSV export)
• Delete your data (delete events, babies, or the entire App)
• Opt-out of iCloud sync (use the App in local-only mode)
• Withdraw consent for AI processing at any time in app Settings
• Revoke caregiver sharing at any time
