Privacy Policy

Last Updated: October 2, 2026

Welcome to நாட்கதிர்: Tamil Calendar ("Naatkathir", "we", "our", or "us"), developed and published by Hornbill Apps. We respect your privacy and are committed to protecting any information processed while using our mobile application.

            Key Summary: We do not sell your personal data. We do not require account registration or collect sensitive personal identities. Permissions such as Location are utilized strictly on-device to deliver accurate astronomical, calendar, and weather data.
        

1. Information We Collect and Process

Our application processes minimal data strictly necessary to provide its core calendar and utility services:

Location Data (Approximate / Precise): With your permission, the app accesses your device's geographical location solely to calculate accurate local sunrise, sunset, Rahu Kalam, Yamagandam, auspicious times (Nalla Neram), and local weather forecasts. Your exact location is never stored on external servers or sold.
Device & Diagnostic Information: We may collect non-personally identifiable diagnostic information (such as operating system version, device model, and crash logs) via Firebase Crashlytics to detect bugs and ensure app stability.
Usage Analytics: Aggregated, anonymous interaction events (e.g. popular features viewed) via Google Analytics for Firebase to improve app quality.

2. Third-Party Services and Advertising

The app integrates trusted, privacy-compliant third-party service providers:

Google AdMob: To support the ongoing maintenance and development of our free service, the app displays advertisements. AdMob may process device identifiers, advertising IDs, and cookies in compliance with Google's Advertising Policies and local privacy laws (including GDPR and CCPA). You can control personalized advertising settings directly through your Android device settings.
Google Play Services: For in-app updates and store services.
Firebase (Analytics & Crashlytics): For crash diagnostics and performance monitoring.

3. Data Storage & Security

All user preferences (such as bookmarked dates, puzzle progress, and custom settings) are stored locally on your device using encrypted/secure local storage. We do not maintain user accounts or passwords on centralized remote servers.

4. Children's Privacy

Our application is intended for general audiences interested in calendar, panchangam, and cultural content. We do not knowingly collect personal identifiable information from children under the age of 13.

5. Your Choices & Permissions

You can grant or revoke permissions (such as Location or Notifications) at any time through your device's system settings under Settings → Apps → நாட்கதிர் (Tamil Calendar) → Permissions.

6. Changes to This Privacy Policy

We may update our Privacy Policy periodically. Any changes will be posted on this page with an updated "Last Updated" date.
