Overview

Daily Sudoku ("the App") is a fully offline sudoku puzzle game. We take your privacy seriously. This policy explains how the App handles your information.

In short: the App does not collect, store, or transmit any of your personal data. All game data stays on your device.

1. Information We Collect

We collect no personal information. Specifically, the App:

• requires no account and collects no name, email, or phone number;
• collects no device identifiers (such as IDFA, IDFV, or Android ID);
• accesses no location, contacts, photos, microphone, or other sensitive data;
• contains no advertising, analytics, or tracking SDKs;
• integrates no third-party data services.

2. Local Data Storage

The App stores only the following game data, locally on your device:

• level progress, star ratings, and best times;
• saved state of an unfinished game (so you can resume);
• your settings (theme, sound, timer mode, etc.);
• achievements and daily-challenge history.

This data never leaves your device. We cannot access it, and no third party can obtain it through the App.

How to delete

• In the App: "Settings → Clear current save progress" removes the corresponding save slot;
• Uninstalling the App deletes all local data.

3. Network & Permissions

• The App does not actively access the network. All puzzles are bundled in the installation package.
• The Daily Challenge puzzle is generated deterministically on-device from the date — no server is involved.
• The App requests no sensitive system permissions such as location, camera, photo library, microphone, or contacts.
• The "Share result" feature uses the system share sheet; you choose what to send, and the App never reads or stores any information about the recipients.

4. Third-Party Services

The App integrates no third-party advertising, analytics, social-login, or payment SDKs, and shares no data with any third party (because we collect none).

5. Children's Privacy

The App is suitable for all ages (4+). Since it collects no user data at all, it does not collect any personal information from children either, consistent with children's online privacy requirements.

6. Data Security

Your game data resides only in the App's on-device sandbox, protected by iOS / Android system-level security. Since no data is transmitted over the network, there is no transmission-related exposure.

7. Changes to This Policy

If this privacy policy changes, we will update this page and revise the effective date. Should any change materially affect data-collection practices, we will additionally notify you prominently within the App.
