Marine Oily Water Separator (package com.fleetwood.marineoilywaterseparator) is published by Anindya Banerjee.

What data is collected

None. The app does not collect, store on a server, share or sell any personal data. It has no accounts, no advertising and no analytics or tracking.

What stays on your device

Your oral practice progress (which questions you marked Got it, Nearly or Missed) and whether Pro is unlocked are stored only on your own device, in the app's private storage. They are removed when you uninstall the app or clear its data.

Network access

The app needs no network access to work. The 3D viewer and all content are bundled inside the app and run offline. The app makes no network requests of its own and contacts no server of ours. The only communication is between the Google Play Billing library and Google Play, to check and complete the optional Pro purchase; for that reason the app's permissions list includes the standard internet and network state permissions that the Play Billing library requires.

Purchases

The optional Pro unlock is a one-time in-app purchase handled entirely by Google Play. Payment details are processed by Google and are never seen by the app or by the author. The app only asks Google Play whether the purchase has been made. Google's own privacy policy applies to purchases.

Children

The app is an educational tool for marine engineering students and does not knowingly collect information from anyone, including children.

Changes

If this policy changes, the new version will be published at the address below.
