Last Updated: August 26, 2026

This Privacy Policy describes how Qamar Calendar ("we", "us", or "our") collects, uses, and shares your information when you use our mobile application (the "App").

1. Information Collection and Use

Our App is designed to provide a comprehensive Hijri Calendar experience. To provide and improve our services, we collect certain information as described below.

1.1 Personal Data

We do not require you to provide personally identifiable information (such as your name, address, or email) to use the basic features of the Qamar Calendar. However, if you contact us for support, we may collect your email address and any other information you provide to assist with your inquiry.

1.2 User-Created Events

The App allows you to create and manage custom events on specific Hijri dates. These events are stored exclusively on your device's local storage. We do not upload, sync, or transmit your custom events to our servers or any third-party services. You have full control over this data, and it is deleted if you clear the App's data or uninstall the App.

When you access the App, we may automatically collect certain information, including:

• Device type, model, and manufacturer
• Operating system and version
• Unique device identifiers (e.g., Firebase Installation ID)
• Language preferences
• App usage statistics and configuration settings

1.4 Push Notifications

The App uses Firebase Cloud Messaging (FCM) to send you important updates and notifications. For this purpose, we collect a unique device token that allows us to deliver these messages to your device. You can opt-out of receiving push notifications at any time through your device settings.

2. Data Usage

We use the collected information for the following purposes:

• To provide and maintain the App's functionality, including local storage of your custom events.
• To synchronize application configurations and Hijri date adjustments using Firebase Realtime Database.
• To send relevant push notifications and alerts.
• To improve the user experience and App performance.

3. Third-Party Services

The App uses third-party services that may collect information used to identify you. These include:

• Google Play Services: Provides core Android functionality.
• Firebase Realtime Database: Used for synchronizing App configurations and data.
• Firebase Cloud Messaging (FCM): Used for sending push notifications.

We encourage you to review the privacy policies of these third-party providers at Google's Privacy Policy page.

4. Data Retention and Deletion

We retain collected information only for as long as necessary to fulfill the purposes outlined in this policy. Your custom events remain on your device until you manually delete them, clear the App data, or uninstall the App. If you wish to have any other data deleted from our records, please contact us at the email address provided below. We will respond to your request within 30 days.

5. Data Security

We value your trust in providing us your information, thus we are striving to use commercially acceptable means of protecting it. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee its absolute security.

6. Children's Privacy

These Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers.
