Privacy Policy - Kalender Nusantara
Last updated: July 13, 2026
This Privacy Policy describes how Kalender Nusantara ("we", "our", "the app") collects, uses, and shares information when you use our mobile application.
1. Information We Collect
Kalender Nusantara does not require user account registration and does not directly collect, transmit, or store personally identifiable information such as your name, email, phone number, or exact physical location on our servers.
Our app operates primarily offline. However, it integrates standard third-party services (described below) that may automatically process technical and device identifiers for the purpose of serving advertisements and facilitating app analytics.
2. Personal Notes and Agenda Data
The app features a custom scheduling and memo functionality. Any personal notes, tasks, agendas, or event reminders that you create are stored 100% locally on your device using an offline Room Database.
This data is entirely private to you, never uploaded to the internet, and will be permanently removed if you choose to uninstall the app or clear its application data through your device settings.
3. Traditional Calculations (Weton & Primbon)
All custom calculations for Weton, Neptu, and Primbon matches are computed locally on your device instantly. We do not transmit or log the dates or parameters you input to any external databases.
4. Advertising (Google AdMob)
We use Google AdMob to display banner, interstitial, and native advertisements within the app to support its continuous and free development. AdMob may collect and process the following types of data:
- Device identifiers (such as Android Advertising ID / GAID)
- IP address and general network location
- App usage logs and user interaction with ad formats
- Ad performance telemetry (impressions, clicks, and load rates)
This data may be used to serve personalized or non-personalized ads, prevent click fraud, and measure promotional statistics. For more information about how Google collects and uses data, please visit policies.google.com/technologies/partner-sites.
You can opt out of personalized advertisements at any time by configuring your device's settings (go to Android Settings, then Google, then Ads) or by visiting adssettings.google.com.
5. Children's Privacy
Kalender Nusantara is suitable for general audiences of all ages. We do not knowingly collect or store any personal data from anyone, including children under 13 years of age. If you are a parent or legal guardian and have any concerns, please contact us.
6. Data Sharing & Third-Party Providers
We do not sell, trade, or distribute your information. Technical details (like mobile advertising IDs) are only processed by our primary advertising network partner (Google AdMob) in strict adherence to standard Google Developer policies.
