Sudoku Blueprint · Last updated: July 12, 2026
Sudoku Blueprint ("the App") is a sudoku puzzle game. This policy explains what information the App handles and how.
The App does not require you to create an account, and it does not have a backend server. All puzzle progress, statistics, difficulty progress, and settings are stored only on your device using Apple's standard local storage (UserDefaults). We do not collect, transmit, or have access to this information.
The App displays banner ads served by Google AdMob. To show ads and measure their performance, AdMob may collect information such as your advertising identifier, approximate location, device information, and app interaction data, in accordance with Google's Privacy Policy.
On iOS, the App requests permission via Apple's App Tracking Transparency framework before using your advertising identifier for personalized ads. You can allow or deny this request, and you can change your choice at any time in Settings → Privacy & Security → Tracking. Purchasing the full unlock removes ads entirely, which also stops AdMob's ad-related data collection within the App.
The App offers an optional one-time purchase to unlock additional content. All purchases are processed entirely by Apple through StoreKit. We do not receive, see, or store your payment information — Apple handles billing according to its own privacy policy.
The App is rated for general audiences and is not directed at children. We do not knowingly collect personal information from children.
We do not sell your personal information. The only data processed by a third party is the advertising data described in Section 2, handled directly by Google AdMob under its own privacy policy.
If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
