Privacy Policy
1. Introduction
This Privacy Policy explains how Lulla ("we", "our", or "us") handles information when you use our mobile application ("the App") on the Apple App Store and Google Play.
The App provides a library of relaxing sounds, soundscape mixing, sleep timers, and lullabies designed to help you fall asleep and rest. We are committed to protecting your privacy and minimizing data collection.
2. Information We Collect
2.1 Information We Do Not Collect
We do not collect or store:
- Your name, email address, or phone number
- Account credentials (the App works without sign-up)
- Audio recordings made on your device
- Photos, contacts, or files from your device
- Precise location data (GPS)
Audio playback and sound mixing happen locally on your device.
2.2 Automatically Collected Information
We collect a limited amount of non-identifying technical data through third-party SDKs:
- Device type and model
- Operating system and version
- App version and language
- Anonymous in-app events (which screens you open, which sound packs you play)
- Crash and diagnostics data
- Approximate region (derived from IP, not GPS)
This data is aggregated and not used to identify you personally.
2.3 Advertising Identifiers
The App is supported by advertising delivered through Google AdMob.
We (the developer) do not collect, store, or have access to your advertising identifier (IDFA on iOS, AAID on Android). These identifiers are handled directly by AdMob and Google under their own privacy policy, and are used by them to serve and measure ads, including general device and network information and anonymous interaction signals (ad impressions, taps).
Because the App itself does not store these identifiers, we cannot delete or reset them from within the App. They are controlled by your device's operating system:
- On iOS, we ask for your permission via App Tracking Transparency before AdMob can track across other apps and websites. You can change this choice at any time in Settings → Privacy & Security → Tracking.
- On Android, you can reset or delete your advertising ID in Settings → Google → Ads.
3. Subscriptions and Payments
The App may offer optional auto-renewable subscriptions (for example, to remove ads or unlock additional sound packs).
- Payments are processed by Apple App Store or Google Play
- We do not receive, see, or store your payment card details
- You can manage and cancel subscriptions in your App Store or Google Play account settings
4. Permissions
Notifications
Used to deliver optional reminders such as "your sleep timer is ending" or scheduled bedtime nudges. You can disable notifications at any time in your device settings.
Background Audio
Used to keep sounds playing when the screen is off or the App is in the background. No permission prompt is required; this is a standard playback capability.
Network Access
Used to:
- Download optional sound packs
- Load and serve advertisements
- Send anonymous analytics and crash reports
The App does not require an account or sign-in.
5. How We Use Information
We use data to:
- Operate and improve App features and stability
- Diagnose crashes and fix bugs
- Understand which soundscapes are most useful
- Serve and measure advertisements
- Comply with legal obligations
We do not:
- Sell your personal data
- Build personalized profiles outside the advertising context permitted by our SDKs
- Listen to or record audio from your microphone
6. Third-Party Services
We use the following third-party services. Each operates under its own privacy policy:
- Google AdMob — advertising delivery and measurement
- Firebase Analytics — anonymous app usage analytics
- Firebase Crashlytics — crash and stability reporting
- Apple App Store / Google Play — distribution, subscriptions, and refunds
These providers may collect data described in their own privacy policies, including device identifiers and advertising IDs.
7. Data Sharing
We do not sell your personal data. We share limited information only with:
- The third-party service providers listed in Section 6, strictly to operate the App
- Authorities, when required by law, court order, or to protect rights and safety
8. Data Security
- Audio content and personal preferences are stored locally on your device
- We do not run our own user database
- Data transmitted to third-party SDKs is encrypted in transit (HTTPS/TLS)
- Despite reasonable safeguards, no method of transmission over the internet is 100% secure
9. Children's Privacy
The App is not directed to children under 13 (or the equivalent minimum age in your country).
We do not knowingly collect personal data from children. If you believe a child has provided us with data, please contact us so we can delete it.
If the App is used on a device shared with a child, advertising and analytics features may collect anonymous device-level data. Parents and guardians can disable ad personalization in device settings or use platform-level parental controls.
10. Your Rights (GDPR / CCPA / UK GDPR)
Depending on where you live, you may have the right to:
- Access the personal data we hold about you
- Request correction or deletion
- Restrict or object to processing
- Withdraw consent (e.g., for tracking or analytics)
- Lodge a complaint with your local data protection authority
Because the App does not maintain user accounts, most personal data can be removed by:
- Turning off ad personalization and tracking in your device settings
- Uninstalling the App
To make a rights request, contact us at the email below.
11. International Data Transfers
Third-party providers we use (Google, Apple, Firebase, AdMob) may process data in countries outside your country of residence, including the United States. These providers maintain safeguards such as Standard Contractual Clauses to protect transferred data.
12. Changes to This Policy
We may update this Privacy Policy from time to time. Updates will be reflected by a new "Effective date" at the top. Material changes will be highlighted within the App or on this page.
