Privacy Policy

Pentarab built the Constella app with a free tier and optional one-time in-app purchases that unlock additional readings and features. This Privacy Policy explains what information the app handles and how your privacy is protected.

Constella does not collect, transmit, or store any personal data on external servers. Your birth information, reading history, and preferences are stored only on your device and never leave it.

Saju and astrology calculations rely on sensitive personal details such as your date, time, and place of birth. We believe that information belongs to you alone, so Constella is designed to run entirely on your device without external data storage.

To generate readings, the app asks for inputs such as:

• Date, time, and location of birth
• Gender (used for traditional Saju rules)
• Optional MBTI type
• Nickname or label you assign to a profile

All of this stays on your device and is used only to calculate and display your readings.

The app stores the following information locally on your device:

• Birth profiles and saved readings
• Reading history and bookmarks
• In-app purchase entitlements
• App settings and preferences

All this data is stored using iOS secure storage and is automatically deleted when you uninstall the app.

Additional readings and features are unlocked through one-time in-app purchases offered via the Apple App Store. All payments and billing are processed by Apple — Pentarab does not receive or store your payment card details, Apple ID, or billing address.

To validate your purchase, the app communicates with Apple's StoreKit and may use Apple's receipt verification services. We may receive an anonymous transaction identifier from Apple solely to confirm entitlement; this identifier is not linked to your personal identity.

Constella does not use any third-party analytics, tracking, or advertising services. We do not integrate with any external SDKs that collect user data. Saju engine calculations run locally on your device using an embedded JavaScript bundle. Purchases are handled by Apple under Apple's own privacy policy.

You have complete control over your data:

• All data stays on your device
• You can delete individual profiles and readings in the app
• Uninstalling the app removes all data permanently

Since all data is stored locally on your device and never transmitted over the internet, your data security depends on your device's security. We recommend:

• Keeping your device password-protected
• Using iOS security features like Face ID or Touch ID
• Keeping your iOS updated with the latest security patches

Constella is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided information through the app, please contact us so we can address it.

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this Privacy Policy periodically for any changes.
