Who we are
Why Sudoku is a classic 9x9 Sudoku app for iPhone and Android, made by S-Block Technologies ("we"). This policy covers the Why Sudoku app.
What we collect
Nothing. We do not collect any personal data, and we receive nothing from the app. Why Sudoku has no account or sign-in, shows no ads, has no in-app purchases, and uses no analytics or tracking. It contains no third-party SDKs that collect data, and it does not use the network.
What stays on your device
Your games, settings and progress are stored on your device, in a local SQLite database in the app's private storage. We never receive any of it. Your phone's own backup (iCloud or Google backup) may include this data, under your Apple or Google account, and restore it on a new phone. Deleting the app removes this data from that phone.
Children
Why Sudoku collects no data from anyone, including children.
Changes to this policy
If we change how Why Sudoku handles data, we will update this page and its effective date.
