PRIVACY POLICY FOR JAMAKOLRISHABAM

Last Updated: August 2026

This Privacy Policy describes how Rishabam School of Astrology ("we", "us", or "our") collects, uses, stores, and protects information when you use the JamakolRishabam mobile application ("Application").

1. INFORMATION WE DO NOT COLLECT

The Application is designed as a privacy-focused, offline-first astrological calculation utility. We do not collect, request, or store your personal information on any servers.

We do not collect or store:

  • Your name, email address, phone number, contacts, or calendar.
  • Device photos, media files, or text messages.
  • Credit card, billing, or any other financial payment information.
  • Precise location data on our servers.
  • Astrological charts, saved places, or custom transit notes on our servers.

2. INFORMATION WE ACCESS AND PROCESS ON YOUR DEVICE

All processing of calculations and user inputs is performed locally on your device.

a. Location Data (GPS)

The Application requests access to your device's location services to determine your geographical coordinates (latitude and longitude).

  • This permission is accessed only on-demand when you explicitly request your current location to perform location-based astrological calculations.
  • This location data is processed locally in real-time to calculate precise transits, house configurations (Bhavas), Arudam, and Udayam.
  • Location coordinates are never transmitted, stored, shared, or uploaded to our servers or any third-party servers.
  • Granting location permission is optional. If you choose not to grant GPS access, you can manually search for a city or enter coordinates to perform calculations.

b. Saved Charts and Custom Places

All chart records, custom location configurations, search history, and transit notes you create are stored locally in a private SQLite database on your device. We do not have access to, nor do we store or backup, your saved charts or custom places.

c. Application Settings

Your preferred configuration options (such as language, dark mode preference, 12/24-hour format, and Ayanamsa preference) are saved locally on your device using key-value storage (AsyncStorage) to persist your preferences between sessions.

d. Internet Access

The Application does not require an active internet connection to perform its core astrological calculations. Where internet access is available, it is used only when you explicitly choose to open external resources, such as our official YouTube channel or support pages.

3. PERMISSIONS AND SYSTEM FEATURES USED BY THE APPLICATION

The Application requests or utilizes the following device permissions and system features to perform its core functions:

  • Location (ACCESS_FINE_LOCATION / ACCESS_COARSE_LOCATION): Used to retrieve coordinates for calculating charts based on your current location.
  • Share Sheet & Document Picker (System Features): Used only when you choose to export charts or share screenshots. These tasks are handled via standard built-in operating system features and do not require granting read/write access to your device's files or external storage.

4. THIRD-PARTY LIBRARIES AND ANONYMOUS TELEMETRY

The Application uses Firebase Analytics and Firebase Crashlytics (provided by Google LLC) to monitor application performance, collect anonymous operational metrics (such as screen transitions, chart save/share actions, language preferences), and diagnose crash reports to maintain application stability.

All telemetry transmitted to Firebase is encrypted in transit using HTTPS. No personal identification, user accounts, email addresses, exact GPS coordinates, saved chart names, or transit notes are ever collected, transmitted, or shared with third parties.

Third-party libraries used solely to provide local application functionality (such as user interface components, astronomical calculation libraries, or mathematical utilities) do not receive, collect, or transmit your personal data.

Distribution platforms such as Google Play or the Apple App Store may collect information independently of the Application (such as installation metrics or crash logs) in accordance with their own privacy policies. We do not control or have access to such data.

5. USER RIGHTS AND CONTROL

Because your data remains exclusively on your device, you have full control over it. You may delete your data at any time by:

  • Deleting charts or places individually within the Application.
  • Clearing the Application's data through your device settings.
  • Uninstalling the Application from your device.

Because we do not store your data on our servers, we cannot recover charts, notes, or settings that are deleted or lost due to device failure, reset, or uninstallation.

6. DATA SECURITY

We rely on the security mechanisms provided by your device's operating system to help protect locally stored data. However, no method of electronic storage can be guaranteed to be completely secure.

7. INTERNATIONAL USERS

The Application is intended for users worldwide. This Privacy Policy applies regardless of your country of residence.

8. CHILDREN'S PRIVACY

Because the Application does not collect personal information from users, we do not knowingly collect or process personal data from children under the age of 13.

9. CHANGES TO THIS PRIVACY POLICY

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date at the top of this document or posting updates within our app store listings.
