Data stored on device
The app stores deck inputs, project records, and settings on your device. Files leave the app only when you choose to export, print, save, or share them.
No Anvilfield account or backend
The app does not create an Anvilfield account, does not sync to an Anvilfield backend, and does not sell personal data.
Included access
The launch app is free. It has no advertising SDK and no analytics SDK.
Sharing
When you use Android share, print, save, mail, or browser actions, the destination you choose handles the file or link under its own policy.
Retention and deletion
Working records remain on your device until you delete them in the app where supported, clear the app's local storage in Android settings, or uninstall the app. Anvilfield does not retain a server-side copy because the app has no Anvilfield account or backend. Files you export or share remain with the destination you chose until you delete them there.
Security
Working records use Android app-scoped storage and the security controls of your device. The app does not transmit project records to Anvilfield. Protect access to your device and review the security and privacy terms of any app or service you choose for exported files.
