Privacy Policy

Last updated: September 09, 2026

Welcome to Finance Calculator Offline. Your privacy is our top priority. This policy outlines our commitment to data security and explains how we handle information within our mobile application.

            The Offline Promise: Our app is designed to function without requiring your personal financial data to be uploaded. Your calculations remain yours alone.
        

1. Information We Collect

Financial Data: All financial inputs, results, and calculation history are stored locally on your device's internal storage using a secure Room database. We do not have access to this data, nor do we transmit it to any external servers.

Technical Data: We may collect non-identifiable technical information (such as device model, OS version, and language settings) to ensure app compatibility and optimize performance.

2. Third-Party Disclosures

To provide a high-quality free experience, we integrate the following industry-standard services:

Google AdMob: Facilitates ad delivery. They may use advertising IDs to show relevant content.
OneSignal: Powers our reminder system and update alerts.
Bishnu International API: Used exclusively to check for critical system maintenance or required security updates.

3. Data Security

Because your data resides on your device, its security is linked to your device's overall safety. We recommend using built-in Android security features like biometrics or PIN codes to protect your local calculation history.

4. Permissions Usage

Network Access: Required to verify app status and load advertisements.
Notifications: Used only if you opt-in for financial reminders.
Vibration: Enhances user experience through tactile feedback.

5. Children's Privacy

Our services are not directed to individuals under the age of 13. We do not intentionally collect data from children.

6. Policy Updates

We may refine this policy to reflect app improvements or regulatory changes. Significant updates will be communicated via app notifications.

7. Contact & Support
