Sudoku

Overview

Sudoku is a classic puzzle game published under the package name com.sudokushudu.www. The app is designed to work without an account, login, or user-generated content. This Privacy Policy explains what information is collected, used, shared, and protected when you use the app.

Information we do not collect directly

We do not require you to create an account. We do not ask for your name, phone number, email address, postal address, contacts, photos, microphone, camera, or precise location. We do not operate chat, social features, or user-generated content inside the app.

Game data stored on your device

The app may store gameplay information locally on your device, such as puzzle progress, best times, daily challenge completion, streaks, campaign progress, selected theme, and similar preferences. This information is used to make the game work and is not used to identify you personally.

Data collected by the app

The app itself may process app activity and app information needed for core gameplay, diagnostics, fraud prevention, security, and app functionality. Most gameplay data is stored locally on your device.

Advertising and third-party services

Sudoku uses Google AdMob to show ads, including rewarded ads that can provide extra hints, notes, or chances in the game. Google and its partners may collect and process information such as device identifiers, advertising identifiers, approximate location, IP address, ad interactions, diagnostics, crash data, and other data described in Google's own policies. This data may be used for advertising, analytics, fraud prevention, security, and service improvement.

You can learn more about how Google uses information from apps at policies.google.com/technologies/partner-sites.

Internet access

The app requests internet and network state permissions so that ads can load and report delivery. Core Sudoku gameplay is designed to work without signing in.

Data sharing

We do not sell your personal information. Data processed by Google AdMob may be shared with Google and advertising partners as described in Google's policies and required for ad delivery, measurement, fraud prevention, and legal compliance.

Data retention and deletion

Local gameplay data remains on your device until you clear app storage or uninstall the app. Data processed by Google AdMob is retained according to Google's own retention policies. You can request privacy-related assistance by contacting us at the email address below.

Security

We use platform-provided storage and standard third-party SDKs to operate the app. No method of transmission or storage is completely secure, but we aim to keep the app limited to the data needed for gameplay and advertising.

Children

Sudoku is a general-audience puzzle game and is not directed specifically to children under 13. If you believe a child has provided personal information to us, contact us and we will take appropriate action.

Your choices

You can reset local game data by clearing the app's storage or uninstalling the app. You may also control advertising personalization through your device settings and Google account settings where available.

Account and data deletion

Sudoku does not create user accounts and does not require login. There is no server-side Sudoku account to delete.

To delete your Sudoku game data from your phone, uninstall the app or clear the app's storage in your device settings. This removes locally stored game progress, settings, best times, daily challenge history, streaks, campaign progress, and theme preferences from that device.

If you contact us by email for support, you may request deletion of that support communication by emailing sudoku_service@outlook.com.

International users

The app is available for users in multiple regions, including English, Hindi, and Thai language environments. Third-party advertising services may process data in countries outside your own, subject to their policies and applicable law.

Changes to this policy

We may update this Privacy Policy when the app changes or when legal, platform, or advertising requirements change. The effective date above will be updated when we make material changes.
