Privacy Policy

SUDOKU · by JR Labs · com.jrlabs.sudoku

1. Overview

SUDOKU is a puzzle game built for entertainment. We believe in keeping things simple: we do not collect, store, or transmit any personal data. Everything stays on your device.

2. Data We Do Not Collect

We do not collect:

• Your name, email address, or any personal identifiers
• Location data
• Device identifiers or advertising IDs
• Usage analytics or crash reports sent to external servers
• Any data that leaves your device

3. Data Stored Locally on Your Device

The app saves game data locally on your device only using Android's standard local storage. This includes:

• Your game progress and saved puzzle state
• Best times and game statistics
• Your daily puzzle streak
• App settings (theme, language, sound preferences)
• Whether you have completed the tutorial

This data is stored using AsyncStorage — a local key-value store that never leaves your device. It is deleted when you uninstall the app or reset your data from within the app.

4. Permissions

SUDOKU requests no special permissions. It does not access your camera, microphone, contacts, location, or any other sensitive device resource. Audio playback uses the standard Android audio API and does not require any permission.

5. Third-Party Services

The app does not integrate with any third-party analytics, advertising, or tracking services. There are no ads, no in-app purchases, and no external SDKs that collect data.

6. Children's Privacy

SUDOKU is suitable for all ages. Because we collect no personal data, there are no special concerns regarding children's privacy. We comply with applicable laws including COPPA and GDPR-K.

7. Changes to This Policy

If we ever change how data is handled (for example, if we add analytics in a future version), we will update this page and note the date above. We encourage you to check this page periodically.
