SilicaShield stores everything you enter only on your phone. Digital NEXUS does not collect, receive, sell, or share any of your data. The app has no account, no ads, no analytics, and no in-app purchases.
The app keeps your selected OSHA Table 1 task parameters, duration, enclosed/outdoor environment flags, optional air-sampling readings, and local field worksheet logbook entries in private local storage on your device. This data never leaves your phone unless you explicitly share or print it.
The app requests zero runtime device permissions (no camera, microphone, location, contacts, or file-system access). The Android manifest declares zero network (INTERNET / ACCESS_NETWORK_STATE) permissions and the app makes zero outbound network requests.
SilicaShield operates 100% offline. All HTML, scripts, styles, and Table 1 calculation logic are packaged locally inside the app with zero external font CDNs, tracking beacons, or cloud services.
SilicaShield is completely free and contains no Google Play Billing library, subscriptions, or paid unlocks.
When you tap Print Worksheet or Share Text Summary, your worksheet is passed only to the Android print manager or sharing app you explicitly choose.
You can clear saved entries inside the app, clear app storage in Android settings, or uninstall SilicaShield to permanently erase all stored data from your device.
SilicaShield is an independent field reference tool by Digital NEXUS. It is not affiliated with, endorsed by, or an official compliance determination by OSHA or the U.S. Department of Labor. Site-specific Written Exposure Control Plans must be reviewed by a Competent Person.
