FlowTest keeps your backflow test records on your phone. Digital NEXUS does not collect, receive, sell or share any of your data. The app has no account, no ads and no analytics.
Your test records (customer, site address, location on site, assembly type, size, manufacturer, model and serial number, test date, gauge readings, notes and result) and your tester details (your name, the tester certification number you type in, your test kit serial and its calibration date). This data is saved in the app's private storage on your device. The app never sends it to us or to anyone else.
The app asks for no device permissions: no camera, microphone, location, contacts or files. It also declares the standard internet and network-state permissions, which need no approval.
From version 1.0.1 the app makes no network requests: it works offline and does not send anything you enter over the internet. (Version 1.0.0 loaded its fonts from Google Fonts when it opened.)
The app is free. From version 1.0.1 it contains no billing library and nothing can be bought in it. (Version 1.0.0 showed paid plans that unlocked without any payment; they are gone.)
If you tap Share or Print on a record, it goes to the app or printer you choose (for example email, a messaging app, a print service or Save as PDF). That only happens when you do it, and what that app does with the record is covered by its own privacy policy.
You can delete single records and the example records in the app. Clearing the app's storage in Android's settings, or uninstalling the app, deletes all of its data from your phone. If Android backup is turned on for your phone, Android may keep a copy of the app's data in your own Google account backup, which you manage in your Google account. Because we hold no data about you, there is nothing for us to delete on our side; you can still write to us with any question.
The app is a work tool for adults and is not directed at children.
FlowTest is an independent app by Digital NEXUS. It is not affiliated with, endorsed by or connected to any water utility, government agency or certification body, and its records are your own, not official test reports.
If this policy changes, the new version will be posted on this page with a new effective date.
