At Lunar Mirror, we believe your personal data should stay personal. This privacy policy explains what minimal information we collect and how we handle it.
We built Lunar Mirror to be privacy-first
- ✅All your data stays on your device
- ✅No user accounts required
- ✅No cloud storage or syncing
- ✅No tracking or advertising
- ✅We don't sell your data (we don't even have access to it)
- 🗑️Delete the app = all your data is deleted
What Information We Collect
1. Location Data
What: Your geographic coordinates (latitude and longitude)
Why: To calculate accurate moon phases, lunar proximity, and zodiac positions for your specific location
How we get it:
- Automatic: If you allow location access, we use your device's GPS
- Manual: If you type a city name, we use Apple's MapKit service to convert it to coordinates
2. Your Journal Entries
What: Your daily ratings for 10 metrics:
- Inner World: Calm, Intuition, Resilience, Reflection
- Outer World: Energy, Social, Focus, Vitality
- Core Self: Mood, Clarity
Plus any notes you choose to add.
Why: To track your patterns over time and correlate them with lunar cycles
3. App Preferences
What:
- Your daily reminder time (default 19:00)
- Notification preferences (on/off)
- Other app settings
How We Use Your Information
All processing happens locally on your device:
- Calculate moon phases using the TinyMoon Swift package (open source, runs locally)
- Display your journal history and analytics
- Show correlations between your metrics and lunar cycles
- Generate your "Lunar Personality" insights
- Send local notifications for daily reminders (if enabled)
- Alert you to special moon events
We never send your journal data, metrics, or personal information to any server.
Third-Party Services
We use minimal third-party services:
Apple MapKit
When: Only when you manually type a location name
What happens: Your typed location (e.g., "Paris") is sent to Apple to get coordinates
Apple's Privacy: Apple Privacy Policy
Apple App Store Analytics
What: Anonymous, aggregated data about app usage (downloads, crashes, device types)
What we don't see: Your personal data, journal entries, or location
Apple's Privacy: App Analytics Privacy
Apple Crash Reports
What: Anonymous technical data when the app crashes
Purpose: To fix bugs and improve stability
What's included: Device type, iOS version, crash logs (no personal data)
TinyMoon Swift Package
What: Open-source astronomical calculations library
How it works: Runs entirely on your device with no external calls
Source: Available on GitHub
Data Storage and Security
Local Storage: All your data is stored in your device's local storage using iOS standard security practices.
No Cloud Backup: We don't use iCloud or any cloud service to store your data.
No Cross-Device Sync: Your data stays on the device where you created it.
Device Security: Your data is protected by your device's security features (passcode, Face ID, Touch ID).
Data Sharing
We do not share, sell, or transfer your personal information to third parties.
The only exception:
- When you manually type a location, that location name is sent to Apple MapKit to get coordinates (see Third-Party Services above)
Your Rights and Choices
Location Permissions
- You can enable or disable location access in your device Settings → Privacy → Location Services → Lunar Mirror
- You can always use manual location entry instead
Notifications
- You can turn off daily reminders in the app's More → Notifications settings
- You can disable all notifications in device Settings → Notifications → Lunar Mirror
Data Deletion
Since all data is stored locally on your device:
- Delete the app = all your data is permanently deleted
- No account to deactivate, no servers to contact
- Your data is completely removed from your device
Data Export
Currently, the app does not include a data export feature. Since all data is local, you can take screenshots of your analytics or manually record your insights.
Children's Privacy
Lunar Mirror is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. Since we don't have user accounts or collect data on servers, we cannot verify users' ages.
If you believe a child under 13 is using the app, please contact us at support@lunarmirror.app.
