Silt Fence Calculator & Bid Privacy Policy

Last updated: July 17, 2026

Silt Fence Calculator & Bid is an offline construction takeoff app from Anvilfield. The app does not create user accounts and does not use an Anvilfield server, cloud sync, ads, or analytics.

Data Stored On Your Device

The app stores project and client names; your optional company, contact, address, phone, email, and license fields; optional general-contractor and foreman recipient fields; plan references and images; traced points; quantities; unit costs; scope notes; pay-period quantities; evidence photos; app settings; whether the single free bid export has been used; and local Pro status on your device.

Plan Files And Photos

You can import plan images and attach ticket photos. These files stay on your device unless you choose to share, print, export, back up, or send them with another app.

Purchases

Optional Pro purchases are handled by Google Play Billing. The app accesses the Google Play product identifier, purchase status, and entitlement state needed to complete a purchase and unlock or restore Pro features. This purchase history is required for purchase and restore functionality, is not used for analytics or advertising, and is not shared by Anvilfield. Anvilfield does not receive your payment card number. Google processes Play transactions under Google's own terms and privacy policy.

Sharing And Exports

When you export a PDF, CSV, PNG, or ZIP, Android may show share targets such as email, Drive, or print. Any data sent after that is handled by the app you choose.

Network Use

The app works without an Anvilfield backend. It may contact Google Play for purchases or restore checks. It may open this privacy policy in your browser when you tap Privacy policy.

Children

This app is for construction professionals. It is not directed to children.

Retention And Deletion

Local projects and settings remain on the device until you delete them in the app, clear Android app storage, or uninstall the app. Anvilfield has no server-side account or project copy to delete. Files you export, back up, or share remain with the destination you chose until you delete them there.

Security

Working records, imported plans, and evidence photos use Android app-scoped storage and your device's security controls. Silt Fence Calculator & Bid does not transmit project records, plan files, or photos to Anvilfield. Protect access to your device and review the terms of any app or service chosen for exported files.
