MarginBase ("the app") is a paid, offline business calculator. We designed it to collect nothing about you. This policy explains, plainly, what that means.
None. MarginBase does not collect, transmit, or share any personal data. It has no user accounts, no sign-in, no cloud, and no servers. It does not contain advertising, analytics, crash reporting, or any third-party tracking SDK.
To make the app useful, MarginBase saves a small amount of data only on your device:
This data never leaves your device. It is stored in the app's private storage and is not transmitted anywhere. You can remove it at any time by clearing the app's storage or uninstalling the app.
MarginBase works fully offline and makes no network requests for its functionality. It does not send your inputs, results, or any usage information over the internet.
MarginBase is a one-time paid app. Your purchase is processed by Google Play, not by us. We do not receive, see, or store your payment details. Google Play's own privacy policy governs the purchase transaction.
MarginBase is a general business utility intended for adults (small-business owners and solo operators). It is not directed to children and is not part of the Google Play Families program.
If this policy changes, we will update the date above and publish the new version at this URL.
