Lunar Lite | Privacy Policy

Last Updated: December 2025

Lunar Lite ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains what information our app collects, how we use it, and the choices you have. Lunar Lite is a device-based security application that uses on-device AI models to analyze basic system behavior and provide security insights. We do not collect, transmit, sell, or share any personal data. All analysis occurs locally on your device.

1. Information We Collect

Lunar Lite only collects a very limited set of device metrics, all of which remain on your device and are used solely to operate our on-device AI detection engines. We do not collect any personally identifiable information.

1.1 Device Behavior Telemetry (On-Device Only)

Lunar Lite processes the following telemetry locally:

• Screen-time activity (total minutes active during each session)
• Battery level changes (to infer unusual background drain patterns)
• Disk usage deltas (to detect abnormal local file growth)
• App-launch frequency (to detect unexpected activity)
• DNS hostnames queried by the device
• File extension frequencies within Lunar Lite's own sandbox (e.g., .so, js, .sh, .zip)

All telemetry stays on your device and never leaves it.

1.2 No Sensitive Data

We do not collect:

• Contacts
• Photos
• Messages
• Browsing history
• Location
• Installed apps list
• Device identifiers (IDFA, IDFV)
• Email, name, or phone number
• Advertising information

1.3 No Tracking

Lunar Lite does not:

• Track users across apps or websites
• Use third-party analytics
• Use ad networks or marketing trackers

2. How We Use Information

All telemetry is processed exclusively on your device using CoreML models for the purpose of:

• Detecting behavioral anomalies
• Flagging potentially malicious DNS patterns
• Identifying malware-like activity inside the app sandbox
• Providing you with on-device security insights
• Enforcing sweep limits (free tier) or unlocking unlimited sweeps (paid tier)

No telemetry is transmitted to our servers or stored off device.

3. Data Storage & Retention

Lunar Lite stores only small, temporary telemetry measurements within the app sandbox.

We do not:

• Upload data to cloud servers
• Create user accounts
• Maintain remote logs
• Sync information across devices

All telemetry resets periodically and is fully deleted if you uninstall the app.

4. Subscription & Payment Information

If you choose to upgrade to a paid plan:

• Payments are processed securely through Apple's In-App Purchase system.
• We do not receive or store your payment information.
• Apple may provide anonymized subscription status to the app (e.g., active/inactive).

5. Children's Privacy

Lunar Lite is safe for all ages and collects no personal data.

For parents who choose to enable expanded protection through supported MDM enrollment:

• All advanced telemetry remains on the child's device.
• No telemetry flows to Lunar Lite, Lunar Defense LLC, or third parties.
• Parents retain full control over MDM enrollment and removal.

We do not knowingly collect personally identifiable information from children.

6. Data Sharing

Lunar Lite does not share, sell, rent, or transfer any information to:

• Third parties
• Advertisers
• Data brokers
• Governments
• Cloud services

There is no scenario in which your telemetry leaves your device.

7. Security

Lunar Lite uses Apple's secure sandboxing and on-device machine learning frameworks. All detection happens offline with:

• No servers
• No databases
• No transmissions
• No remote logging

Your device handles all processing internally.

8. Your Choices

You may:

• Use Lunar Lite without creating an account
• Disable notifications at any time
• Uninstall the app to delete all stored telemetry
• Choose free tier or paid tier

There are no user data exports because we do not collect or store your information.

9. Changes to This Privacy Policy

We may update this Privacy Policy as Lunar Lite evolves. Material changes will be reflected by updating the "Last Updated" date above.
