Frontier Steel Weight Calc Privacy Policy

This policy describes how Frontier Steel Weight Calc handles data. It is an offline metal-weight and material-cost calculator from JD Frontiers.

JD Frontiers | Effective November 6, 2026

Data on your device

Calculator inputs, unfinished quotes, saved jobs, material prices, notes and preferences are kept in Android's private storage for this app. App-managed automatic cloud backup and automatic device transfer are disabled.

No collection, sale or tracking

The app does not send your app data to JD Frontiers and has no internet permission. JD Frontiers does not collect or sell data through this app. There are no accounts, advertising, analytics or tracking SDKs.

Exports, backups and sharing

You choose whether to export CSV, save or import a JSON backup, or share a quote. Android's file picker and share sheet transfer the content to the location or receiving app you select. Those providers may use their own storage or network services, and their privacy policies apply. A portable backup contains saved jobs and settings, not unfinished calculator inputs.

Retention and deletion

Local data remains until you delete it. Delete saved jobs in Jobs, and use Clear piece or Start new quote to clear working inputs. Previous restore copies can remain privately on the device for recovery. Clearing this app's Android storage or uninstalling removes its private data, including drafts and recovery copies. Exported files and shared copies remain outside the app until you delete them at their destinations.
