This Privacy Policy describes how Daily Sudoku Puzzle ("we," "us," or "our") handles information when you use the Daily Sudoku Puzzle mobile application.
Daily Sudoku Puzzle is a classic Sudoku puzzle game that lets you:
Daily Sudoku Puzzle does not require an account and does not ask you to provide your name, email address, phone number, precise location, contacts, photos, camera access, or health information.
The app stores gameplay and preference data locally on your device so the game can function properly. This may include:
This local game data is stored on your device using Android DataStore. We do not upload this saved game or settings data to our servers.
Daily Sudoku Puzzle uses Google AdMob to display banner advertisements. Google AdMob may collect or process information such as device identifiers, advertising ID, IP address, approximate location inferred from IP address, app interactions, ad views, diagnostics, and other data described in Google's policies. Daily Sudoku Puzzle declares the Google advertising ID permission for this purpose.
We configure AdMob with child-directed and under-age-of-consent treatment and a maximum G-rated ad content setting. However, Google's handling of advertising data is governed by Google's own privacy policies and consent requirements.
The app may request a public list of other developer apps from https://healthplate.org/api/projects. This request does not require an account and does not send your saved Sudoku game data. Like most web requests, our server may receive standard technical information such as IP address, request time, and user agent string for security, reliability, and server operations.
We use information only to operate and improve the app experience:
We do not sell your personal information. We do not share your local Sudoku progress or settings with third parties.
Information may be processed by third-party services used by the app, including Google AdMob and Google Play services, as described in their own privacy policies. We may also disclose information if required by law or to protect our rights, users, or services.
Daily Sudoku Puzzle uses or may interact with the following third-party services:
We encourage you to review Google's privacy policy and AdMob disclosures for more information about Google's data practices.
Your saved puzzle and settings remain on your device until you clear the saved puzzle, clear app data, or uninstall the app. We do not keep a server copy of your Sudoku progress or settings.
Server logs for requests to healthplate.org may be retained for a limited period for security, diagnostics, and operational purposes.
Daily Sudoku Puzzle is designed to be family-friendly. The app does not require accounts and does not knowingly collect personal information from children. Ads are configured for child-directed treatment, under-age-of-consent treatment where applicable, and G-rated ad content. If you believe a child has provided personal information to us, please contact us and we will take appropriate action.
We use reasonable safeguards to protect our services. Local app data is protected by Android's app sandbox and device security features. No method of electronic storage or transmission is completely secure, so we cannot guarantee absolute security.
If you use Daily Sudoku Puzzle outside the United States, information processed by third-party services or our public server endpoints may be processed in the United States or other countries where those services operate.
We may update this Privacy Policy from time to time. When we make changes, we will update the "Last Updated" date at the top of this page. Continued use of the app after an update means you accept the updated policy.

We typically respond within 24-48 hours during business days.
