Privacy Policy

Effective Date: February 7, 2026

1. Our Commitment to Privacy: Refrigeration CycleAnalyst is committed to protecting your privacy. We believe your data belongs to you. This policy outlines our practices regarding information collection for our universal app across Apple, Google, and Amazon platforms.

2. Offline-First Computation: The core of RCA is entirely internal. All refrigeration cycle computations and app functions are performed locally on your device. The app does not require an internet connection for its primary calculation features.

3. Data Collection & Third-Party Services

While we do not collect or require personal information (such as names, email addresses, or phone numbers) and do not support user account logins, we utilize third-party telemetry and quality tools to maintain service integrity and improve application performance:

• Firebase Services: Firebase automatically assigns a "Firebase Installation ID" to your device. This non-identifying string is used solely to track free trial periods and maintain service functionality.
• PostHog Telemetry & Analytics: We transmit non-identifying, anonymous diagnostic telemetry and feature interactions over encrypted connections (HTTPS) to PostHog. This data includes general application interactions, operational metric selections, system diagnostic performance, and anonymous session identifiers. It is used strictly for functional performance analysis, diagnostic troubleshooting, and app quality improvements.
• No Real-World Identity Association: Because there are no user accounts or logins, telemetry and performance metrics are entirely anonymous and are never linked to your personal real-world identity.

4. Subscriptions & Payments: All financial transactions and subscription statuses are handled securely by the respective App Stores (Apple App Store, Google Play Store, or Amazon Appstore). RCA does not see or store your credit card information or personal billing details.

5. Data Retention & Deletion: Since we do not create or store user accounts, there is no personal data to delete. Trial-related identifiers are automatically handled by the Firebase system and are not used for marketing or tracking outside of the RCA app.

6. Updates to This Policy: We may update this Privacy Policy from time to time. Any changes will be posted within the app.
