GaugeGate DC is an offline field tool from Anvilfield. The app does not require an account, does not use an Anvilfield backend, and does not send core calculation data to a server.
The app stores run cards, balance entries, unit/theme preferences, and export drafts on the device. The user controls what job or witness text they enter.
When the user exports or shares a PDF, CSV, or ZIP, Android hands that file to the app the user chooses, such as email, print, or cloud storage. That destination app controls what happens next.
The app has no ads, no analytics, and no account sync. Core calculations do not call a server. Google Play Billing may use Google Play services for paid unlocks.
If the user buys or restores Pro, Google Play handles the payment and may process purchase and device data for that transaction. GaugeGate DC stores only a local signed entitlement receipt derived from the Play purchase so the unlock can work offline.
The app may ask Google Play to show an optional in-app review prompt after a saved run. If the user rates or reviews the app, Google Play handles that review flow. GaugeGate DC does not send field calculation data through the review prompt.
