Dryer Airflow Test is an offline field tool from Anvilfield. The app does not require an account, does not use an Anvilfield backend, and does not send your readings, photos, or reports to a server.
The app stores sites, dryers, readings, lint checklist results, burner notes, labeled photos, reports, and unit and theme preferences on the device. You control what site, customer, or tech text you enter.
When you export or share a PDF, CSV, JSON, ZIP, or photo bundle, Android hands that file to the app you choose, such as email, print, or cloud storage. That destination app controls what happens next.
The app uses the camera only when you tap to take or attach a photo for a report line, such as a lint screen, transition, termination, or nameplate. Photos stay on your device unless you export or share them.
The app has no ads, no analytics, and no account sync. Core calculations do not call a server. Google Play Billing uses Google Play services only for the paid Pro unlock.
If you buy or restore the one-time $9.99 Pro unlock, Google Play handles the payment and may process purchase and device data for that transaction. Dryer Airflow Test stores only the resulting unlock state on the device so Pro features work offline. Anvilfield does not receive your full payment card details.
The app does not request or use location.
