Privacy Policy: Crystal Index

Lunar Computing, Inc. ("we," "us," or "our") develops the Crystal Index iOS app. This Privacy Policy explains how Crystal Index handles information when you use the app.

Crystal Index stores saved crystals, notes, collection state, widget preferences, and browsing preferences on your device.

1. Data stored in the app

Crystal Index is designed around local, on-device storage. Depending on which features you use, the app may store:

• Saved crystals, favourites, notes, collection state, and local reference preferences
• Widget preferences and premium access state

This data is used to provide app functionality and is not sold, used for advertising, or shared with data brokers.

2. Optional permissions

• Widgets: Widgets read local Crystal Index data to display selected or daily reference items.

You can revoke iOS permissions at any time in Settings. Some app features may stop working after a required permission is revoked.

3. iCloud and on-device processing

If iCloud is enabled, saved crystals and notes may sync via Apple CloudKit to your own devices.

Apple controls iCloud account authentication and CloudKit infrastructure. We do not receive your Apple ID password, payment information, or private iCloud account credentials.

4. Purchases

Premium access is processed by Apple in-app purchase and managed with RevenueCat. We do not receive your Apple ID, payment card, or billing address.

5. Third-party services

Depending on the features you use, Crystal Index may interact with:

• Apple CloudKit
• Apple in-app purchase
• RevenueCat

Third-party services process data according to their own privacy policies. We only use them for app functionality, entitlement verification, system permissions, or user-requested actions.

6. Health, wellbeing, and reference content

Crystal Index is not a medical device and does not provide medical, psychological, legal, financial, or other professional advice. Any journalling, reference, or study content is provided for personal use and self-reflection only. It should not be used to diagnose, treat, prevent, or make decisions about a health condition.

7. Your choices

• Delete local app data from inside the app where available.
• Delete the app from your device to remove local app data stored in the app sandbox.
• Manage iCloud data from iOS Settings if you enabled iCloud sync.
• Cancel or manage subscriptions in iOS Settings under your Apple ID subscriptions.
• Revoke optional permissions, such as Microphone, Speech, or Notifications, in iOS Settings.
