Privacy Policy

Sudoku Master · Effective date: 12 July 2026

This Privacy Policy explains how Sudoku Master (the “App”, package com.sudoku.master.app), developed and maintained by Yash Dhola (“we”, “us”, “our”), handles information when you use it. By using the App, you agree to this policy.

In short: Sudoku Master is designed to be privacy-friendly. Your game progress and settings stay on your device. We do not show ads, we do not use advertising identifiers, and we do not sell your data. The only data that leaves your device is anonymous crash diagnostics and your purchase status.

1. Information We Collect

a. Data stored only on your device

Your gameplay data — saved games, statistics, history, achievements, hint balance, and app settings — is stored locally on your device (using on-device storage). It is not transmitted to us and is removed when you uninstall the App (it may be included in a device backup you control, e.g. Google Backup).

b. Crash and diagnostic data

We use Google Firebase Crashlytics to record crashes and errors so we can fix bugs and improve stability. This may include your device model, operating system version, app version, and a diagnostic crash trace. This data is not used to personally identify you.

c. App configuration

We use Google Firebase Remote Config to manage feature settings. Fetching configuration involves a network request to Google and may process an anonymous Firebase installation identifier.

d. Purchases

In-app purchases (such as Premium and hint packs) are processed by Google Play Billing. We receive your purchase and entitlement status so we can unlock what you bought. We do not receive or store your payment card details — those are handled entirely by Google.

e. Notifications

The App may offer optional reminder notifications powered by OneSignal. When notifications are active, OneSignal processes a device push token and basic device information to deliver them. Push notifications are not enabled in the current version of the App.

f. No advertising

This App does not display third-party advertisements and does not collect or use an advertising identifier.

2. How We Use Information

3. Third-Party Services

The App relies on the following service providers, each with its own privacy policy:

We do not sell your personal information or share it for cross-app advertising or tracking.

4. Data Retention and Deletion

5. Children's Privacy

The App is intended for a general audience and is not directed to children under 13 (or the minimum age of digital consent in your region). We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will address it.

6. Your Rights

Depending on where you live (e.g. under the GDPR or CCPA), you may have the right to access, correct, delete, or restrict processing of your personal data, and to object to certain processing. Because most data stays on your device, you can exercise many of these rights directly by clearing the App's data or uninstalling it. For anything else, contact us using the details below.

7. Security

We take reasonable technical and organizational measures to protect information. Gameplay data is kept on your device, and data in transit to service providers is protected using industry-standard encryption. No method of transmission or storage is 100% secure, however, and we cannot guarantee absolute security.

8. International Users

Our service providers may process data in countries other than yours. Where required, appropriate safeguards are applied by those providers as described in their privacy policies.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the “Effective date” above and, where appropriate, within the App. Continued use of the App after changes take effect constitutes acceptance of the updated policy.
