Sudoku (“the App”) is published by Zenith Labs (“we”, “us”). This policy explains what data the App handles. Classic Sudoku with four difficulties and notes.
Data we collect
The App stores your settings and content locally on your device and does not require an account. We do not collect personally identifying information ourselves.
Advertising & consent
The App shows ads via Google AdMob, which may collect device identifiers and usage data to serve and measure ads. For users in regions that require it (e.g. the EU and UK), the App presents a Google UMP consent form letting you choose personalized vs. non-personalized ads. You can reset your advertising ID or limit ad tracking in your device settings at any time. Buying the Pro upgrade removes all ads.
In-app purchases
The one-time Pro upgrade (remove ads and unlock extra features) is processed by Google Play. We do not receive or store your payment details.
Diagnostics
Google Play Services may collect aggregate crash and performance diagnostics. See Google’s privacy information.
Children
The App is not directed at children under 13 and we do not knowingly collect their data.
Your choices
Reset your advertising ID or limit ad tracking in your device settings. Uninstalling the App removes all locally stored data.
