Privacy Policy

Sudoku Shelter - Cozy Cats · Last updated: July 15, 2026

This Privacy Policy explains how Sudoku Shelter ("we", "our", or "the app") handles your information. We designed Sudoku Shelter to collect as little data as possible.

1. Information We Do Not Collect

Sudoku Shelter does not require an account. We do not collect your name, email address, contacts, photos, or precise location. Your detailed game progress (including puzzle saves, coins, and cat collection) is stored on your device.

2. Optional Gameplay and Device Analytics

After completing the tutorial, we ask whether you would like to share limited gameplay and device information to help us improve game balance and future content. We use Unity Analytics only if you choose “Help Out.” Choosing “No Thanks” does not affect gameplay, rewards, or purchases.

When enabled, Unity Analytics may process pseudonymous installation and device identifiers, standard session events, technical app and device information (such as app version, operating system, and device characteristics), app performance and diagnostic information, and approximate location derived from an IP address. Platform device identifiers may be processed where available and permitted by the platform.

We also send limited custom gameplay events: tutorial completion, puzzle-clear statistics, rewarded-ad completion, in-app purchase product and reward information, item and zone progress, cat discovery progress, and periodic high-level progress summaries. These events use internal game IDs and numbers only. We do not intentionally include your name, email address, payment details, precise location, or the numbers you enter into Sudoku puzzles.

We use this optional Analytics data only to understand and improve the game. We do not use it to select or personalize ads. You can change this choice later from Settings > Analytics Preferences in the app. See Unity's Privacy Policy for more information about Unity's data practices.

3. Unity Engine Diagnostics

Unity Engine Diagnostics may collect limited software and hardware performance information to help us monitor the stability and integrity of the app. This diagnostic collection is managed separately from the optional Unity Analytics choice and is not used to personalize advertising.

4. Advertising

Sudoku Shelter displays ads served by Google AdMob. AdMob may collect and use device information to provide and improve advertising, including:

On iOS, we ask for your permission through Apple's App Tracking Transparency (ATT) prompt before any tracking takes place. If you decline, you will still see ads, but they will not be personalized using cross-app tracking. Where required (e.g., in the EEA/UK), we also show a consent form powered by Google's User Messaging Platform, and you can change your choice at any time.

For details on how Google uses data, see How Google uses information from sites or apps that use its services and the Google Privacy Policy.

5. In-App Purchases

Sudoku Shelter offers optional in-app purchases (coin packs and ad removal). All payments are processed by Apple (App Store) or Google (Google Play). We never see or store your payment details. Purchase entitlements (such as "Remove Ads") are verified through the store and saved on your device.

6. Children's Privacy

Sudoku Shelter is suitable for general audiences. We do not knowingly collect personal information from children. Advertising in the app is provided by Google AdMob in accordance with its policies.

7. Data Deletion

Deleting the app removes detailed game progress stored on your device. Changing your Analytics Preference stops future optional Unity Analytics collection, but does not automatically delete Analytics data already sent to Unity. There is no server-side account. To request deletion of Analytics data or ask about your privacy rights, contact us at the email address below.

8. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated date above.
