FireFlow 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 local fire pump flow test profiles, pitot nozzle readings, discharge curves, and field worksheet notes in the app's private local storage on your device. This data stays on your device and is never transmitted to us or any third party.
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.
FireFlow operates 100% offline. All assets, scripts, and calculations are bundled locally in the app with zero external font CDNs, telemetry endpoints, or cloud synchronization.
FireFlow is completely free and includes no Google Play Billing library, subscriptions, or paywalls.
If you tap Print Worksheet or Share Text Summary, the generated worksheet goes only to the Android print service or share target you choose. Any handling after sharing is governed by that destination app's own privacy policy.
You can reset or clear saved test profiles inside the app at any time, or clear app storage / uninstall FireFlow to permanently remove all local records from your device.
FireFlow is an independent fire pump hydraulic calculation tool by Digital NEXUS. It is not affiliated with, endorsed by, or an official standard of the National Fire Protection Association (NFPA) or any authority having jurisdiction (AHJ). Field tests must always be reviewed by a qualified professional.
