Effective date: June 12, 2026

This Privacy Policy explains how rewernator ("we", "our", or "us") collects, uses, and protects information in the mobile game Sudidler: Sudoku (Android package name com.rewernator.sudidler).

If you have questions about this Privacy Policy or your data, contact us at marcin.rewertyn@gmail.com.

Summary

  • Sudidler: Sudoku does not show third-party ads.
  • The game does not ask you to create an account.
  • The game stores progress, settings, consent choices, and purchase entitlements locally on your device.
  • Analytics and crash diagnostics are used only when you allow them in the game's privacy or analytics consent screen.
  • In-app purchases are processed by Google Play. We do not receive your payment card details.

Information Stored on Your Device

The game may store information locally on your device so that it can work correctly and remember your choices. This may include:

  • game progress, active puzzles, completed puzzles, daily challenge progress, achievements, and local statistics;
  • settings such as language, gameplay preferences, and privacy or analytics choices;
  • purchase entitlements used to unlock content you bought or restored;
  • local technical data needed to operate the game.

This local information is generally kept on your device until you reset it in the game, clear the app data, or uninstall the app. Your device operating system may also keep backups depending on your device settings.

Analytics and Diagnostics

If you choose to allow analytics and diagnostics, the game may use Google Firebase services, including Firebase Analytics and Firebase Crashlytics, to help us understand how the game is used and to fix technical problems.

This data may include:

  • gameplay events such as puzzle difficulty, board size, hints, mistakes, completion results, daily challenge activity, and feature usage;
  • app interaction events such as screen or button usage;
  • purchase flow events such as product identifiers, purchase status, restore status, or purchase errors;
  • technical information such as app version, build number, platform, network state, crash reports, nonfatal errors, and diagnostic logs;
  • pseudonymous identifiers such as Firebase app instance identifiers or an app-generated session identifier.

We use this information to improve stability, balance gameplay, troubleshoot purchase and restore flows, understand feature usage, and improve the app. We do not use this information to show ads in the game.

Consent Choices

Analytics and crash diagnostics are controlled by your choice in the game. You can continue without analytics. You can also change your analytics choice later in the game's settings or privacy options. If you turn analytics off, future analytics and crash diagnostic collection controlled by this choice will be disabled.

In-App Purchases

Sudidler: Sudoku may offer in-app purchases through Google Play. Google Play processes the payment. We do not collect or receive your payment card number, bank account details, or full billing information.

The game may receive and use purchase-related information such as product identifiers, purchase status, receipt or order information, price and currency metadata, and entitlement status. This information is used to complete purchases, restore purchases, unlock content, prevent purchase errors, and maintain your access to purchased items.

Advertising

Sudidler: Sudoku does not show third-party advertising and does not use an active advertising SDK. The game is designed not to use the Android Advertising ID for advertising. Earlier legacy versions of the game may have included third-party advertising features. These versions could display ads and may have allowed advertising providers to process certain technical data, such as device information, advertising identifiers, app interaction data, and ad performance data, in accordance with their own privacy policies.

Information We Do Not Ask For

The game itself does not ask you to provide:

  • your name, email address, phone number, or account password;
  • photos, videos, audio recordings, contacts, messages, calendar data, or health data;
  • precise location data;
  • payment card numbers or bank account details.

If you contact us by email, we will receive the information you choose to send, such as your email address and message content. We use that information only to respond to your request, provide support, and keep reasonable records of the communication.

Third-Party Services

The game may use third-party services that process data according to their own privacy terms and service terms. These services may include:

  • Google Firebase, including Firebase Analytics and Firebase Crashlytics, for analytics and diagnostics when you consent;
  • Google Play and Google Play Billing for in-app purchases, payment processing, and purchase restoration;
  • Unity services used to support Unity Purchasing and app operation.

These providers may process technical information such as device and app identifiers, IP address, approximate region derived from network data, app version, operating system information, diagnostics, and purchase-related service data as needed to provide their services.

How We Use Information

We use information for the following purposes:

  • to provide the game, save progress, remember settings, and unlock purchased content;
  • to process, validate, and restore in-app purchases;
  • to understand app usage and improve gameplay balance when analytics is allowed;
  • to diagnose crashes, errors, and technical problems when diagnostics are allowed;
  • to respond to support requests;
  • to comply with legal, security, and platform requirements.

Data Sharing

We do not sell your personal information. We may share or allow processing of information with service providers only as needed to operate the game and related services, including Google Firebase, Google Play, and Unity services.

We may also disclose information if required by law, to protect the security of the app, to prevent fraud, or to protect our rights and users.

Data Retention

Local game data is kept on your device until you delete it, clear app data, reset relevant in-game data, or uninstall the app. Analytics, crash diagnostics, and purchase-related service records are retained according to the retention settings and policies of the relevant service providers and only as long as needed for the purposes described in this policy.

Your Choices and Rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or object to certain processing of your information. You can:

  • change your analytics and diagnostics choice in the game;
  • delete local app data through the game, your device settings, or uninstalling the app;
  • contact us at marcin.rewertyn@gmail.com for privacy questions or requests.

Because the game does not require an account, we may need enough information from you to locate relevant records, if any exist. Some purchase records are controlled by Google Play and may need to be managed through your Google account or Google Play support.

Children's Privacy

Our game is intended for a general audience and is not specifically directed to children under the age of 13, or the equivalent minimum age required by applicable law in the user’s jurisdiction.

We do not knowingly collect personal information directly from children. The game does not require account registration, does not ask users to provide their name, email address, phone number, photos, messages, or other personal contact information, and does not include social features, public profiles, or user-generated content sharing.

If the game uses analytics, crash reporting, advertising, in-app purchases, or other third-party services, such services may process limited technical, device, usage, or transaction-related information as described in this Privacy Policy and in the privacy policies of those third-party service providers.

If you are a parent or legal guardian and you believe that your child has provided personal information to us, or that personal information about your child has been collected in a way that is not described in this Privacy Policy, please contact us at: marcin.rewertyn@gmail.com. We will review the request and take reasonable steps to delete such information where required by applicable law.

We encourage parents and legal guardians to monitor their children’s use of apps, games, and online services.

International Processing

The services used by the game may process information in countries other than your own. Where required, we and our service providers rely on appropriate legal bases and safeguards for such processing.

Changes to This Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the effective date above. Continued use of the game after an updated policy is published means the updated policy applies from that date.
