Privacy Policy

milliSudoku is designed to be private by default. This page explains, in plain language, what information is (and is not) collected when you use the app.

No data collected

No personal data is collected

milliSudoku does not collect, transmit, sell, or share any personal data.

In other words: there are no accounts, no analytics, no advertising identifiers, no tracking, and no third-party SDKs that collect data.
