This Privacy Policy describes how Lullamb ("the App"), developed by Mark Gravely ("we", "us", or "our"), handles your information when you use the App.

1. Data We Collect

Lullamb does not require an account, sign-in, or registration. We do not collect your name, email address, contacts, location, photos, or browsing activity.

The only data that leaves your device relates to subscription management:

  • Anonymous user ID and purchase receipt: When you purchase a Lullamb Plus subscription, RevenueCat receives an anonymous device-based user ID and the purchase receipt from Apple to verify and maintain your entitlement across app reinstalls.

All sounds play offline — no audio data is ever transmitted.

2. Service Providers

We rely on the following service providers:

  • RevenueCat — manages subscription entitlement verification. Receives an anonymous user ID and your Apple purchase receipt. Governed by RevenueCat's Privacy Policy.
  • Apple App Store — processes all Lullamb Plus subscription payments. We never see or store your payment card details. Apple's handling of your data is governed by Apple's Privacy Policy.

We do not sell your data and do not share it with third parties for their own marketing.

3. Analytics

Lullamb does not include any analytics SDK. We do not track how you use the App.

4. Children's Privacy

Lullamb is used by parents and caregivers. The App itself does not interact with, address, or collect information from children. If you believe a child has independently provided us with information, contact us and we will delete it.

5. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date above reflects the most recent change. Continued use of the App after changes constitutes acceptance of the updated policy.
