Soroban Beat Privacy Policy

Established: November 12, 2026

PLUS E, KK (株式会社プラス・イー, referred to below as “we,” “us,” or “our”) sets out the following policy for handling information relating to users of our iOS application, Soroban Beat (the “App”).

1. Our Approach

We respect users’ privacy and handle information only to the extent necessary to provide the App.

The App is designed to manage learning records and settings primarily on the user’s device. It does not include a function that automatically transmits these records or settings to our servers.

2. Information Handled by the App

The App may store the following information on the user’s device:

This information is used to provide the App’s features, display learning progress, and improve convenience for users.

3. Collection of Personal Information

The App does not include an account registration function that requires users to provide their name, address, telephone number, email address, or similar information.

The App also does not include functions that obtain users’ location information or advertising identifiers for advertising or tracking purposes.

However, when you contact us, we may receive information necessary to respond to your inquiry, such as your email address and the contents of your message.

4. In-App Purchases

The App offers access to certain features through in-app purchases.

In-app purchases use Apple’s StoreKit. Purchases, verification of purchase status, and restoration of purchases are handled through Apple’s systems.

We do not directly collect or store users’ credit card numbers or bank account information through the App.

For information about how Apple handles information, please see Apple’s Privacy Policy.

5. Operation Logs and Troubleshooting

The version of the App distributed through the App Store does not record detailed operation logs, such as touch locations, bead operation results, or the time elapsed during operations.

Development builds alone record these operation logs locally on the device for testing and troubleshooting. The App does not include a function that automatically sends these logs to us.

If a user provides operation logs to us as part of development or testing, we use them only to investigate issues and improve quality.

Learning records, such as the number of correct answers, course completion status, and progress needed to resume practice, are separate from operation logs. They are stored on the device for the purposes described in Section 2.

6. Disclosure to Third Parties

We do not disclose users’ personal information received through inquiries or similar communications to third parties without their consent, except as required or otherwise permitted by law.

The App uses Apple’s services for in-app purchases. If you open an external link in the App, the privacy policy and other terms of the linked service apply.

7. Retention and Deletion

Learning records and settings stored on the device are retained for as long as needed to use the App.

Deleting the App from your device will normally delete the App’s locally stored data. Data stored separately through operating system backups or similar services must be managed according to the procedures of those services.

Information we receive through inquiries or similar communications is deleted within a reasonable period after our response and any necessary follow-up are complete, unless we are required by law or other applicable obligations to retain it.

8. Security Measures

We take appropriate security measures to help prevent unauthorized access to, disclosure of, or loss of information we receive.

9. Changes to This Policy

We may revise this policy in response to changes in laws, the App’s features, or how information is handled.

Updated versions will be posted on our official website or through other appropriate channels. Where necessary, we will also notify users within the App.

10. Contact Us

For inquiries about this policy or how personal information is handled, or to request access to, correction of, or deletion of personal information we have received, please contact us:
