Terms of Service

1. Parties and Scope

1.1 These Terms are a legal agreement between you and us regarding use of the App and related services.

1.2 These Terms apply to the iOS App Sudoku (Bundle ID: com.orangestudio.sudoku.ios), updates, and the features and services we provide through the App.

1.3 If you are under 18 (or the age of majority in your jurisdiction), you should read these Terms with a parent or guardian and use the App only with their consent.

2. The Service

2.1 The App is a logic puzzle game offering classic puzzles, daily challenges, multiple difficulties, hints, notes, a timer, and statistics. Features may vary by released version.

2.2 Some features are premium features unlocked by App Store in-app purchase or subscription, including unlimited hints, premium board themes, and planned expansions that unlock according to Premium entitlements after launch.

2.3 Free users may use core features such as classic puzzles and daily challenges. Free users have a daily hint limit (as shown in the App).

2.4 We may modify, suspend, or discontinue features at any time and will notify you of material changes by reasonable means (such as in-app notices or release notes).

2.5 The App is for entertainment and mental exercise only and does not constitute professional advice. You should not rely on game results or hints as the sole basis for study, exams, or other important decisions.

3. Accounts and Purchases

3.1 The App does not require a separate account. Purchases, subscriptions, refunds, and restore purchases are completed through the Apple App Store and are subject to Apple's Media Services Terms and the Apple Standard EULA.

3.2 Subscriptions (monthly and yearly) auto-renew for the period confirmed in the App Store until you cancel in iOS Settings → Apple ID → Subscriptions. After cancellation, paid entitlements for the current billing period generally remain available until the period ends.

3.3 Lifetime Premium is a one-time purchase, not a subscription. Entitlements are as described on the purchase screen and in Premium.

3.4 Price, trial (if any), availability, and refunds follow App Store display and Apple policy. For billing issues, contact Apple Support first.

3.5 Example product identifiers (subject to App Store Connect configuration):

• Monthly Premium: com.juzipie.sudoku.vip.monthly
• Yearly Premium: com.juzipie.sudoku.vip.yearly
• Lifetime Premium: com.juzipie.sudoku.vip.lifetime

4. Acceptable Use

When using the App, you agree to:

4.1 comply with these Terms and all applicable laws;

4.2 not reverse engineer, decompile, or disassemble the App (except where expressly permitted by law), crack, tamper with, or attempt to extract source code;

4.3 not use the App for unlawful, infringing, harassing, fraudulent, or otherwise harmful activity;

4.4 not interfere with or disrupt the App, Apple services, or related networks;

4.5 take responsibility for your game progress and local data, and keep your Apple ID secure.

5. User Data

5.1 Game progress, statistics, and settings generated in the App belong to you and are stored primarily on your device.

5.2 Uninstalling the App deletes local game data on the device (unless the system or you make a separate backup). We are not liable for local data loss caused by uninstalling, device damage, or system failure.

5.3 We may process de-identified or pseudonymous usage data through Google Firebase Analytics to understand feature usage and improve the product. Details are set out in our Privacy Policy.

6. Intellectual Property

6.1 The App and its software, interface design, icons, copy, puzzles, and implementation (other than open-source components) are owned by us or our licensors.

6.2 These Terms do not transfer any such rights. We grant you a personal, non-transferable, non-exclusive, revocable license to use the App on a lawfully obtained device in accordance with these Terms.

6.3 You may not copy, modify, distribute, sell, or commercially exploit any part of the App without our written permission.

7. Third-Party Services

7.1 The App relies on Apple system services (including App Store and StoreKit). Availability, terms, and privacy practices of those services are Apple's responsibility.

7.2 The App uses Google Firebase Analytics for product analytics (such as screen views, button events, in-app purchase completion, and share channels). Details of related data processing are set out in our Privacy Policy. Availability, terms, and privacy practices of those services are Google / Firebase's responsibility.

7.3 The App may contain links to third-party websites or services (such as the App Store review page). We are not responsible for third-party content or services; you access them at your own risk and subject to their terms.

8. Disclaimer

8.1 The App is provided on an "as is" and "as available" basis. To the maximum extent permitted by law, we make no express or implied warranties of merchantability, fitness for a particular purpose, accuracy, completeness, uninterrupted operation, or error-free performance.

8.2 To the extent permitted by law, we are not liable for data loss, purchase verification failure, or service interruption caused by network conditions, device failure, system updates, Apple or Google service interruption, or force majeure.

9. Limitation of Liability

9.1 To the maximum extent permitted by law, we and our affiliates, directors, employees, and agents are not liable for any indirect, incidental, special, punitive, or consequential damages arising from use of or inability to use the App (including lost profits, data loss, or business interruption).

9.2 In any event, our total liability under these Terms or relating to the App will not exceed the amounts you paid us directly for the related services in the 12 months before the dispute (or, if you used the App for free or did not pay us directly, RMB 100 or equivalent, whichever higher amount applicable law requires).

9.3 Some jurisdictions do not allow certain exclusions or limitations; those limits apply only to the extent permitted there.

10. Termination

10.1 You may stop using the App at any time by uninstalling it.

10.2 If you breach these Terms, we may limit or terminate your right to use the App without prior notice.

10.3 After termination, you must stop using the App. Provisions that by nature should survive (including intellectual property, disclaimers, limitation of liability, and dispute resolution) remain in effect.

11. Changes to These Terms

We may revise these Terms from time to time. Material changes will be communicated by in-app notice, release notes, or other reasonable means. If you continue to use the App after a change takes effect, you accept the revised Terms; if you do not agree, stop using and uninstall the App.

12. Governing Law and Disputes

12.1 The formation, validity, interpretation, and dispute resolution of these Terms are governed by the laws of the People's Republic of China (for this purpose excluding the laws of the Hong Kong SAR, Macao SAR, and Taiwan), without regard to conflict-of-law rules.

12.2 Disputes should first be resolved through good-faith negotiation. If negotiation fails, either party may submit the dispute to a people's court with jurisdiction at our principal place of business.

12.3 Mandatory consumer-protection rights in your jurisdiction that cannot be waived remain unaffected.
