PolaritySolver DC Privacy Policy

Effective date: June 3, 2026

PolaritySolver DC is designed as an offline field tool from Anvilfield. It has no account, no backend, no cloud sync, no ads, and no analytics.

The app stores rack configs, saved polarity records, theme settings, defaults, and the count used for the free reverse diagnostic on the device. This data stays on the device unless you choose to export it.

Export and printing are user initiated. If you share a PDF or CSV through the Android share sheet, that destination app, service, or printer handles the file under its own policy. Anvilfield does not receive a copy.

The only network use is the one-time Pro purchase and restore. Purchases are handled by Google Play Billing over HTTPS. Google and Google Play billing processes purchase and account data for billing and restore-purchase flows. PolaritySolver DC stores only the local entitlement state needed to keep Pro available offline.

The app requests no camera, location, microphone, contacts, Bluetooth, or advertising id permission. The INTERNET permission is present only so the purchase and restore flow can reach the billing service.

To delete app data, clear saved configs inside the app, or clear PolaritySolver DC storage or uninstall the app from Android settings. Remove generated export files from any folder or share destination where you saved them.
