The short version
AnchorProof stores your inspection records on your device. Anvilfield does not sell, rent, or share your job data.
Data stored on your device
The app can store project names, addresses, EOR and AHJ notes, anchor sets, ESR product presets, measured anchor values, hole-cleaning checks, adhesive lot and cure details, proof-load results, deficiencies, optional photos, inspector name, certificate number, signature image, settings, Pro entitlement state, and generated PDF files.
This data stays in app storage unless you export, print, share, delete, or back up the device with Android tools you control.
Photos and signature
AnchorProof can request the Android Camera permission when you choose to capture evidence for a deficiency, or use the photo picker when you choose an existing evidence photo. It can also store a signature image for reports. These images are used only for the local inspection record and exported files you create.
Network use
The inspection engine, saved projects, ESR presets, proof-load planner, signature, and PDF generation work without internet. Google Play Billing may use network access to buy or restore the one-time Pro unlock. If AnchorProof is configured with Anvilfield's Pro entitlement verifier, the app may send the Google Play purchase token to Anvilfield over HTTPS to verify the unlock. The verifier does not receive project, ESR, measurement, photo, signature, or report data. Android share and print services may use network access only when you choose a destination that needs it.
Purchases
Pro purchases are handled by Google Play Billing. Google processes the payment under Google's terms. AnchorProof stores a local entitlement so paid features keep working offline after purchase. A configured Anvilfield verifier uses the purchase token only to confirm the Pro entitlement.
Analytics and ads
AnchorProof has no ad SDK, no analytics SDK, and no tracking SDK.
Children
AnchorProof is a professional trade tool for adults. It is not directed to children.
Deleting local data
You can delete individual projects in the app. Settings also includes Clear local data, which removes saved projects, inspections, deficiencies, presets, routes, ESR library entries, signed report files, signature, and inspector profile from the device while preserving the Google Play Pro entitlement cache. You can also remove all local data by uninstalling AnchorProof or clearing app storage in Android settings.
Changes
If a future version changes data handling, Anvilfield will update this policy and the Google Play Data Safety details before that version ships.
