Privacy Policy

This Privacy Policy ("Policy") applies to the memory-training game "Memory Blink" (Japanese title: シカクキオク) (the "App") and describes how the App's developer ("Developer", "we", or "us") collects, uses, and shares information in connection with your use of the App. By using the App, you agree to the practices described in this Policy.

This Policy is the English translation of the original Japanese version. In the event of any inconsistency between the Japanese and English versions, the Japanese version shall prevail.

1. Information We Collect

The App does not ask you to enter your name, email address, phone number, or similar information, and it does not require you to create an account. The App handles the following information.

1.1 Information Stored on Your Device

• Game records (clear times, per-level progress and completion status, consecutive-day play streaks, and other activity records).
• App settings and preferences (such as notification on/off).

This information is stored only on your device (in the App's local storage) and is not transmitted to our servers or to any third party. If you delete the App, this information is removed from your device.

1.2 Information Collected in Connection with Advertising

The App is provided free of charge and displays ads using Google AdMob, provided by Google LLC ("Google"), to support its operation. To deliver, display, and measure ads and to prevent fraud, Google and parties involved in ad delivery may collect and use the following information in connection with your use of the App:

• Advertising identifiers (such as the Android Advertising ID [AAID] and the iOS Identifier for Advertisers [IDFA]).
• IP address and coarse location (country/region level) inferred from the IP address.
• Device information (device model, OS version, language and region settings, screen size).
• Information about ad interactions, such as impressions and clicks.

The handling of this information is governed by the privacy policies of Google and the other providers involved. For information about how Google uses this data, please see the Google Privacy Policy and How Google uses information from sites or apps that use its services.

1.3 Consent Management (UMP)

The App uses Google's User Messaging Platform (UMP). In regions where the EU General Data Protection Regulation (GDPR) or similar laws apply, a consent form is presented before ads are requested. Depending on your consent, you will be shown either personalized or non-personalized ads.

1.4 App Tracking Transparency on iOS (ATT)

On iOS, using the advertising identifier (IDFA) for personalized ads may require permission under Apple's App Tracking Transparency (ATT) framework. The App may request such permission where necessary. If you do not grant permission, you will be shown non-personalized ads.

1.5 Notifications

The App may use local notifications (notifications scheduled on your device) to encourage continued use. These notifications are generated and managed entirely on your device; the App does not use a push-notification server or device token and does not transmit any information externally in connection with notifications. You can turn off notifications from your device settings or from within the App.

1.6 Information Collected for Analytics and Crash Reporting

The App uses Firebase Analytics and Firebase Crashlytics, provided by Google, to understand usage and to detect and fix problems and improve quality. Through these services, the following information is sent to Google: an anonymous app instance identifier assigned per app installation, device information (device model, OS version, language and region settings), usage events such as screen views and interactions within the App, and crash information when the App crashes (such as the location of the crash, stack traces, and device state at that time). This information does not include data that directly identifies you, such as your name. For information about how Google uses this data, please see the Google Privacy Policy.

2. How We Collect Information

• Automatically on your device, as you play the App.
• Automatically via the Google Mobile Ads (AdMob) SDK, in connection with the display of ads.
• Automatically via the Firebase SDK, in connection with analytics and crash reporting.

3. How We Use Information

We use the information we collect to:

• Provide, maintain, and operate the App (including saving and displaying records and managing progress).
• Deliver, display, and measure ads within the App and prevent fraud.
• Diagnose and fix bugs and improve the quality of the App.
• Respond to inquiries from users.
• Comply with applicable laws and respond to lawful requests.

4. Sharing and External Transmission

4.1 Sharing with Third Parties

We do not share your information with third parties except:

• with your consent;
• to comply with applicable laws or respond to lawful requests from courts, law enforcement, or other public authorities;
• when necessary to protect the life, body, or property of any person and it is difficult to obtain your consent;
• with the service providers described in Section 4.2, to the extent necessary to fulfill the purposes described in this Policy;
• in connection with a corporate transaction such as a merger, acquisition, or sale of assets.

4.2 Service Providers and International Transfers

To operate the App, we transmit certain information to the following service providers. These providers may be located outside Japan, including in the United States, and information may be transferred to and stored in those countries.

Transmission of information to service providers located in the United States may constitute a cross-border transfer of personal data to a third party in a foreign country under Article 28 of Japan's Act on the Protection of Personal Information. Such transfers are made on the basis of your consent to this Policy. Information about the personal data protection regime of the United States, and about the safeguards each provider has implemented, is available on request through the contact in Section 10.

5. Paid Plan (Subscription)

The App offers a paid plan (an auto-renewable monthly subscription) that removes ads. When you purchase, restore, or start a trial, payment is processed by Apple (App Store) or Google (Google Play). We also use the subscription management service provided by RevenueCat, Inc. to manage purchase status, and information such as transaction ID, product ID, subscription status, and an anonymous app-generated user identifier is processed through Apple/Google and RevenueCat. We use this information to verify and maintain your entitlement. We do not collect credit card numbers or other payment instrument details directly.

6. Retention

• Information stored on your device (Section 1.1) is retained on your device until you delete it or uninstall the App.
• The retention of advertising-related information (Section 1.2) is governed by the policies of Google and the other providers involved.
• The retention of analytics and crash-reporting information (Section 1.6) is governed by Google's policies.

7. Your Rights and Choices

You can manage ad personalization from your device settings (iOS: Settings → Privacy & Security → Tracking, or Apple Advertising; Android: Settings → Google → Ads), including resetting your advertising identifier and opting out of personalized ads. You can also uninstall the App to prevent any further transmission of advertising-related information. Where applicable law (including the EU/UK GDPR and the CCPA/CPRA) grants you rights such as access, deletion, or opt-out, you may exercise them by contacting us at the address in Section 10. We do not "sell" or "share" personal information as those terms are defined under the CCPA/CPRA. We may ask for additional information to verify your identity.

8. Children's Privacy

The App is not primarily directed to children under 13 (or the equivalent age under applicable local law). We do not knowingly collect personal information from such children. If we become aware that we have collected information from a child under 13 without verifiable parental consent, we will promptly delete it. Parents or guardians who believe their child may have provided information through the App may contact us using the information in Section 10.

9. Security

We take reasonable technical and organizational measures to protect information against loss, misuse, unauthorized access, disclosure, alteration, and destruction. Communication between the App and external services is encrypted in transit. However, no method of transmission over the Internet or electronic storage is fully secure, and we cannot guarantee absolute security.
