StrengthGate DC Privacy Policy

Effective date: June 17, 2026

StrengthGate DC is an offline field tool from Anvilfield. The app does not require an account, does not use ads, does not include analytics, and does not sync pour or concrete data to a backend.

Data Stored On Device

The app stores job and pour names, mix and curve data, cylinder break pairs, logger serials, logged temperatures, thresholds, verification records, release evidence (including any photo you attach), settings, and generated export file paths on your device.

Data Sharing

The app shares data only when you choose to export or share a release PDF, curve PDF, or temperature CSV through Android share targets such as email, Drive, print, or another app. Those destination apps handle the data under their own policies.

Purchases

Google Play Billing, handles monthly, annual, lifetime purchases, and restore requests. The app reads purchase and entitlement status to unlock paid features. Google Play billing receives only the data needed to validate a purchase. StrengthGate DC does not send pour or concrete data to an Anvilfield backend.

Permissions

Release builds include Android Internet and network-state permission, used only so Google Play Billing (via Google Play billing) can validate purchases over HTTPS; the maturity engine, curve validator, pour ledger, and exports run fully offline. The camera or photo picker is used only when you choose to attach release evidence. Export sharing uses Android system share and file-provider behavior when you request it.
