Privacy Policy for Compose Calculator

Effective Date: October 27, 2026 • Version: 1.0.1

This Privacy Policy describes how Compose Calculator (“the Application”, “we”, “us”, or “our”), developed by Jesus Daniel Medina Cruz, collects, protects, and uses information.

            Summary: Compose Calculator does not collect, store, transmit, or share any personal information, device identifiers, or user data. All calculations run strictly on your device.
        

1. Information Collection and Processing

Compose Calculator is designed with full privacy by default:

No Personal Information: We do not collect or request names, email addresses, phone numbers, geographic locations, or account credentials.
Local On-Device Execution: All mathematical calculations, expressions, and user inputs are processed entirely in memory on your physical device. No input data is ever uploaded to remote servers or third-party cloud services.
No Analytics or Tracking Identifiers: We do not collect advertising identifiers (e.g., Google Advertising ID / AAID) or track user behaviors across applications.

2. Device Permissions

The Application does not require or request sensitive runtime device permissions:

No access to Camera or Microphone.
No access to Device Location (GPS / Network).
No access to Contacts, Photos, Media, or External Storage.
No background tracking services.

3. Third-Party Services

The production distribution of Compose Calculator does not bundle third-party tracking, advertising, or behavioral analytics SDKs. No user data is ever shared with, sold to, or monetized by third parties.

4. Children’s Privacy

The Application complies with COPPA (Children’s Online Privacy Protection Act), GDPR, and the Google Play Families Policy. Since no personal data is collected from any user, we do not knowingly collect personal information from children under the age of 13.

5. Data Security

Because all operations occur locally within the operating system’s secure application sandbox, your inputs and calculations remain entirely confidential and under your personal control.

6. Changes to This Policy

We may periodically update this Privacy Policy to reflect application updates or regulatory requirements. Any modifications will be posted here with an updated effective date.
