5. Information from Third Parties

We may receive limited information from third parties when necessary to provide the Services.

5.1 App Stores and Payment Platforms

The App is currently provided without paid in-app purchases. However, if paid features, subscriptions, ad-removal features, or other paid services are introduced in the future, purchases may be processed by the Apple App Store, Google Play, or another applicable platform.

We do not collect or store your full payment card number, bank account information, CVV, or other complete financial credentials.

If paid services are introduced, we may receive limited transaction-related information, such as purchase status, product identifier, purchase date, transaction identifier, receipt or token information, and refund or cancellation status.

We would use this information to provide purchased features, verify transactions, restore purchases, prevent fraud, respond to support requests, and comply with legal obligations.

5.2 Advertising, Analytics, and Technical Service Providers

We may receive reports or aggregated information from advertising, analytics, crash reporting, or technical service providers. This may include advertising performance reports, crash reports, device category information, usage statistics, and fraud prevention information.

6. How We Use Information

We use collected information for the following purposes:

to provide, operate, and maintain the Services;
to save game progress and settings;
to provide gameplay features, stages, levels, tutorials, hints, rewards, and other in-game functions;

to provide rewarded advertisements and grant in-game rewards;

to analyze usage trends and understand how the Services are used;
to prevent cheating, fraud, invalid advertising traffic, unauthorized access, abuse, and security incidents;
to enforce our Terms of Use and other policies;
to comply with laws, regulations, legal processes, and requests from authorities;
to protect the rights, property, safety, and legitimate interests of users, third parties, and us;
to perform internal business operations, such as recordkeeping, audits, and service management.

7. Legal Bases for Processing

If you are located in a jurisdiction where a legal basis is required for processing personal information, such as the European Economic Area, the United Kingdom, or Switzerland, we process personal information based on one or more of the following legal bases:

performance of a contract, where processing is necessary to provide the Services you request;
legitimate interests, such as improving the Services, ensuring security, preventing fraud, responding to inquiries, and maintaining service functionality;
consent, where required by law, including for personalized advertising, app tracking permission, push notifications, or certain device permissions;
compliance with legal obligations, such as tax, accounting, consumer protection, platform, or legal request obligations.

Where we rely on consent, you may withdraw your consent at any time through your device settings, in-app privacy settings where available, or by contacting us. Withdrawal of consent does not affect the lawfulness of processing based on consent before withdrawal.

8. Advertising

The Services may include advertisements provided by third-party advertising networks, such as Google AdMob or other advertising partners.

Advertising partners may collect or process information from your device to show advertisements, provide rewarded advertisements, measure ad performance, prevent fraud and invalid traffic, limit ad frequency, and provide contextual or personalized advertisements where permitted by law and your choices.

Depending on your region and device settings, you may be asked for consent before personalized advertising or app tracking is enabled. If you decline or withdraw consent, you may still see advertisements, but they may be less relevant to your interests.

You can manage certain advertising preferences through your device settings, including limiting ad tracking, resetting your advertising identifier, disabling personalized ads, managing app tracking permission on iOS, and changing Google advertising settings on Android.

Third-party advertising partners process information under their own privacy policies. We encourage you to review the privacy policies of the advertising partners and platforms used in the Services.

9. Local Storage and Similar Technologies

The Services may use local storage, device storage, browser storage, or similar technologies to store information necessary for the Services to function.

Such information may include:

game progress;
stage information;
level progress;
selected board size;
sound and BGM settings;
tutorial state or tutorial usage;
hint usage;
advertisement-related counters;
app store review request status;
saved puzzle state;
user preferences;
temporary technical data.

These technologies help us provide game continuity, improve user experience, remember settings, and maintain service functionality.

You may be able to delete locally stored information by clearing app data, deleting the App, clearing browser storage, or using device settings. However, doing so may reset your progress, settings, and other game data.

10. App Store Ratings and Reviews

The App may use app store rating and review request features provided by Apple, Google, or other applicable app stores.

We may store limited local information on your device related to review request timing, such as whether a review request has recently been attempted. This helps avoid requesting reviews too frequently and improves user experience.

Whether a rating or review prompt is actually displayed is controlled by the applicable app store or operating system. We do not receive private information about whether you submitted a rating or review through the prompt, unless such information is made available publicly or through the applicable app store’s developer tools.

Ratings and reviews submitted through the Apple App Store, Google Play, or other app stores are handled by the applicable platform and are subject to that platform’s terms and privacy policy.

11. Push Notifications

At present, the App does not require push notifications for normal gameplay.

If the Services provide push notifications in the future, we may ask for your permission to send notifications. Notifications may include service updates, gameplay reminders, event information, or other app-related messages.

You can disable push notifications at any time through your device settings.

12. Device Permissions

The Services may request certain device permissions only when necessary for specific features.

Depending on the features provided, permissions may include network access to connect to the internet, load ads, process purchases if introduced, and provide online features if introduced; notification permission if push notifications are introduced; photo or media access if image upload or sharing features are introduced; and camera access if camera-based features are introduced.

You can manage permissions through your device settings. Disabling certain permissions may limit the availability or functionality of some features.

At present, the App is not designed to require camera access, microphone access, precise location access, contact list access, or photo library access for normal gameplay.

13. How We Share Information

We do not sell your personal information in the traditional sense for money. However, depending on applicable privacy laws, sharing certain identifiers or advertising-related data with advertising partners for personalized or targeted advertising may be considered a “sale,” “sharing,” or “targeted advertising.”

We may share information with the following categories of recipients.

13.1 Service Providers

We may share information with service providers that perform services on our behalf, including hosting providers, analytics providers, crash reporting providers, advertising providers, customer support tools, payment verification services if paid services are introduced, and fraud prevention and security providers.

These providers process information only as necessary to provide their services to us, subject to applicable legal and contractual obligations.

13.2 Advertising Partners

We may share identifiers, device information, usage information, and advertising interaction information with advertising partners to display ads, measure ad performance, provide rewarded ads, limit ad frequency, and prevent fraud.

13.3 App Stores and Payment Platforms

14. International Data Transfers

Your information may be processed, stored, or transferred in countries or regions outside your country of residence.

These countries or regions may have data protection laws that differ from those in your jurisdiction. Where required by applicable law, we will use appropriate safeguards for international data transfers, such as contractual protections, standard contractual clauses, adequacy decisions, or other legally recognized mechanisms.

15. Data Retention

We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

Retention periods may vary depending on the type of information and the purpose of processing. For example, gameplay and settings data stored locally may be retained while the App remains installed or while necessary to provide the Services; customer support records may be retained for a reasonable period to handle follow-up inquiries, prevent abuse, and maintain business records; purchase records, if paid services are introduced, may be retained as necessary for purchase verification, fraud prevention, accounting, tax, and legal obligations; security logs may be retained as necessary to detect, investigate, and prevent fraud, cheating, abuse, and security incidents; and anonymized or aggregated data may be retained indefinitely, provided it can no longer reasonably identify you.

When information is no longer necessary, we will delete, anonymize, or otherwise process it in accordance with applicable law.

16. Data Security

We use reasonable administrative, technical, and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration, disclosure, or destruction.

However, no method of transmission over the internet or electronic storage is completely secure. We cannot guarantee absolute security of information.

You are also responsible for maintaining the security of your device, platform account, app store account, and any credentials associated with the Services.
