BOOK-BOOK Chagama Privacy Policy

BOOK-BOOK Chagama (hereinafter referred to as the “Operator”) hereby establishes this Privacy Policy (hereinafter referred to as this “Policy”) regarding the handling of personal information and usage data entrusted to us by users in connection with the application “BOOK-BOOK Chagama” (hereinafter referred to as the “App”).

Article 1 (Information We Collect and How We Collect It)

In providing the App, the Operator may collect the following user information.

  1. Information you provide directly
  • Account registration information: email address and password
  • External service linkage information: if you choose an external social login such as Google Sign-In, the identifier (ID) and registered email address obtained from that external service
  1. Payment-related information
  • Paid plans on Android are charged by Google Play. Paid plans on the website are charged by Stripe. Card numbers are handled by those companies and are not stored on the Operator’s servers. The Operator stores the plan type, the paid period, and the country used for pricing.
  1. Information collected automatically through use of the App (including future expansions)
  • Usage logs and statistics: reading time within the App, pages read, operation history, and other reading statistics
  • Device information: OS version, device type, language settings, and similar information about the device you use

Article 2 (Purposes of Use)

The Operator uses collected information for the following purposes.

  1. To create App accounts, verify identity, and manage users
  2. To confirm purchases of paid plans and to manage and provide subscriptions
  3. To provide features that visualize, analyze, and display the user’s own reading records and reading statistics
  4. To perform statistics and analysis for bug fixes, updates, and service improvements
  5. To respond to user inquiries and to notify users of important information

Article 3 (Storage and Management of Information)

  1. Book data imported into the App (such as content files) is stored only on the user’s device (local environment) and is not transmitted to or stored on the Operator’s servers.
  2. Account information and data necessary for the purposes set out in Article 2 (such as reading statistics) are appropriately managed on secure servers administered by the Operator.

Article 4 (Restrictions on Third-Party Disclosure)

The Operator will not provide collected personal information to third parties without the user’s consent, except in the following cases.

  1. When required by law
  2. When necessary to protect a person’s life, body, or property, and obtaining the individual’s consent is difficult
  3. When cooperation is necessary for a national or local government agency, or a party entrusted by such an agency, to perform duties prescribed by law, and obtaining the individual’s consent may impede performance of those duties (including lawful disclosure requests from courts, police, or other public authorities)

Article 5 (Account deletion)

You can delete your BOOK-BOOK Chagama account as follows.

  1. Open https://book-book-chagama.4u-utouto.com/en/mypage
  2. Sign in with your email and password, or with a Google account
  3. Open Delete account in the menu, choose one reason, confirm, and delete the account

Data that is deleted: email address, account ID, the signed-in device ID, and the subscription status on the Operator’s ledger.

Data that remains:

  • Book files stay only on your device. They are not on the Operator’s servers, and deleting the account does not remove them from the device.
  • The reason for leaving is kept without the email address, for improving the service.
  • Transaction records that the law requires us to keep, such as billing records, are kept for the period required by that law.

A remaining paid period cannot be used after the account is deleted, and amounts already paid are not refunded. A Google Play subscription is not cancelled here. Deleting the account removes the app account. The purchase itself is managed by Google Play. Cancel it in Google Play to stop the next charge. A website (Stripe) subscription is cancelled by the Operator when the account is deleted.

To request disclosure or correction of registered information, contact the Operator through the designated inquiry channel.

Article 6 (Changes to This Policy)

The Operator may amend this Policy as necessary due to legal amendments or additions or changes to App features. The amended Privacy Policy becomes effective when posted in the App or on the official website.

Article 7 (Contact)

For inquiries regarding this Policy or questions about the handling of personal information, please contact us via the inquiry form in the App or through the channel designated by the Operator.
