Privacy Policy

1. Information stored on your device

The App stores the following information on your device to provide training features and retain your settings:

• Training records, such as answer history, accuracy, scores, and stage progress
• Settings, such as volume, note names, question ranges, and reference notes
• The expiration time of ad-free periods earned by watching rewarded videos
• Settings and scores transferred from earlier versions, and information retained to protect data during migration

The App does not include a feature that sends these training records or settings to a server managed by the Developer. Depending on your device and operating system settings, this information may be included in operating system backups.

The App does not record audio using your device’s microphone.

2. Advertising and data transmission

The App uses Google AdMob (Google Mobile Ads SDK) and the User Messaging Platform (UMP), provided by Google LLC. When requesting or displaying ads and managing consent, Google and other advertising service providers may collect and process the following information:

• Your IP address and the approximate location inferred from it
• Device- and app-related identifiers, including advertising identifiers when available
• Diagnostic and performance information, such as crashes and app launch times
• Advertising interactions, such as impressions, clicks, and video views
• Consent and preference information relating to advertising and privacy settings

This information may be used to deliver ads, measure their effectiveness, improve services, prevent fraud, and manage consent. The information actually processed depends on your device settings, region, consent choices, and the advertising services used.

The App requests ads when ad requests are permitted. Please also refer to Google’s policies for information about how its advertising services handle data.

3. In-app purchases

The App uses Apple’s App Store and StoreKit for one-time purchases that remove ads. To provide purchases, verify and restore entitlements, and reflect refunds or revocations, the App processes purchase-related information, such as product identifiers, transaction status, and transaction dates. Information about the original purchase of the App may also be used to verify entitlements from the earlier paid version.

Apple handles the information required for payment. The Developer does not receive payment details such as credit card numbers. The App does not include a feature that stores purchase information on the Developer’s own server.

4. Advertising choices

Depending on your region and consent status, the App may display a notice about advertising choices. When privacy options need to be made available, you can review and change them through “広告のプライバシー設定” (Ad Privacy Settings) on the App’s Settings or Ad-Free screen.

If you allow tracking through iOS App Tracking Transparency (ATT), the advertising identifier may be used to link activity across other companies’ apps and websites for advertising and ad measurement. You can use the App without allowing tracking. Without permission, the App requests ads with personalization disabled. You can change ATT permission in your device’s Settings. Advertising consent and ATT permission are handled separately.

Watching rewarded video ads is optional. Completing a video gives you 30 minutes without ads. You may also choose a one-time purchase to remove ads. Removing ads stops subsequent ads within the App; it does not delete information already collected by external services.

You can also use the advertising and tracking settings provided by your operating system. Refer to Apple’s and Google’s guidance for instructions and details about what those settings affect.

5. Data retention and deletion

Training records and settings remain on your device for as long as needed to use the App. Some training history may be replaced with aggregate information to limit the number of saved records. Ad-free periods earned by watching videos end when they expire.

You can delete data stored locally by the App by deleting the App from your device. However, data may be restored from an operating system backup. Please check your device or Apple settings to manage backups.

Deleting the App does not cancel or refund purchases. You may be able to restore purchased entitlements after reinstalling it. For retention periods, deletion, and other rights relating to information handled by Apple or Google, refer to their policies and available procedures.

6. External services and data management

The App uses external services as needed for the advertising and purchase features described above. The Developer does not sell your locally stored training records or settings or independently provide them to advertising companies.

Information sent to external services is managed under the relevant provider’s policies and applicable laws and may be processed outside your country of residence. Refer to each service provider’s guidance on reviewing, choosing how to use, or deleting information and exercising other rights available in your region.

7. Website hosting

This website is hosted on Google’s Firebase Hosting. Google may process access-related information, such as IP addresses, to deliver the website and help keep it secure.

This website does not contain ads, analytics tags, or a contact form. The App does not include a feature that stores training records in Firebase.

8. Policy changes and operator

This policy may be revised to reflect changes to the App’s features or external services. Revised terms will be published on this page with an updated revision date. Where notice or consent is required by law, appropriate measures will be taken.
