Roof Framing Calc: 3D Metric is built to process structural framing dimensions and visualization parameters locally on your device.

All inputs entered by the user (such as span, pitch angle, and rafter centres) and all generated output data (such as rafter cut dimensions, 2D cross-section diagrams, and animated 3D roof frame assemblies) are processed and rendered strictly on the mobile device.

No calculation inputs or designs are uploaded to our servers or stored externally.

3. Analytics & Diagnostics

The App may collect anonymous, aggregated usage diagnostics through standard third-party developer services (such as Google Firebase Analytics, Apple App Analytics, and Google Play Console) for performance monitoring and crash reporting purposes.

No personally identifiable information (PII) or user roof calculations are collected, shared, or transmitted.

4. Data Storage

The App stores user input preferences and application settings locally on the device.

No user calculations, configurations, or personal data are stored externally or transmitted to our servers.

6. Permissions

The App may request limited permissions for:
- Saving/exporting generated 2D diagrams and 3D views to the device's storage or photo library
