Mokumoku (Reading Bank)

Terms of Use

The promises we make to each other when you use Mokumoku.

Last updated: October 29, 2026

These Terms of Use (the "Terms") set out the conditions for using the app "Mokumoku (Reading Bank)" (formerly BookBank) and its related web pages (together, the "Service") provided by Ryo Tsuzukihashi (the "Operator"). By using the Service, you agree to these Terms.

Article 1 (The Service)

The Service lets you record the books you buy, their prices and your reading notes, and review them with totals.

Your records are, as a rule, stored on your own device. If you create an account or subscribe to the paid plan, you can use the features described in the following articles.

Article 2 (Accounts)

When you start using the Service, you choose whether to sign in with your Apple ID or Google account, or to start as a guest. Even as a guest, an anonymous account (user ID) is created for features such as friends. Guests can become friends and receive recommendations, but cannot recommend books to other users. Backup is available when you sign in with your Apple ID or Google account. Guests can connect an Apple ID or Google account later.

If you sign in with an Apple ID or Google account, you can also connect the other one to the same account. If you lose access to one of them, you can sign in with the other and return to the same account. You cannot connect an account that is already used by another account of the Service.

You are responsible for managing your account and must not let any third party use it.

You can delete your account at any time from My Page in the app. When you delete it, the data stored on the Operator's servers is erased and cannot be restored.

Article 3 (Paid plan)

The Service offers an auto-renewing subscription, the "Super Mokumoku Plan" (the "Paid Plan"). The price, period and contents are shown on the purchase screen.

Payment is made through the store where you got the app (Apple's App Store or Google Play). Your account for that store is charged when you confirm the purchase.

The Paid Plan renews automatically unless auto-renewal is turned off at least 24 hours before the end of the current period. On iPhone and iPad, go to Settings → Apple ID → Subscriptions; on Android, go to Google Play → Payments & subscriptions → Subscriptions.

Refunds after purchase follow the rules of each store. The Operator cannot issue refunds directly.

When the Paid Plan ends, features exclusive to it become unavailable and the passbook design returns to the standard one. Backups deposited on the server are deleted 7 days after the plan ends. If you return to the Paid Plan before then, they are not deleted.

Article 4 (Friends and recommendations)

Users who become friends can see each other's list of recorded books. You can choose in the app's settings what to show, such as reading notes and amounts.

Messages sent with recommendations, display names and profiles are shown to the other user. Do not send content that infringes others' rights or that may make others uncomfortable.

When the Operator receives a report of a problematic post, the Operator may review it and stop its display or suspend the account.

Article 5 (Links to bookstores)

The Service may show links to pages where you can buy books. Some links are part of affiliate programs, and the Operator may receive a referral fee when you buy through them. The amount you pay does not change.

Purchases, delivery and returns at linked bookstores are governed by each store's terms.

Article 6 (Prohibited conduct)

  • Acts that violate laws or public order and morals
  • Acts that infringe the copyrights, portrait rights, privacy or other rights of other users or third parties
  • Impersonating other users, harassment or defamation
  • Using the friends or recommendation features for advertising, promotion or solicitation
  • Placing an excessive load on the Service's servers or network, or accessing them without authorization
  • Disassembling or modifying the Service, or using it in ways the Operator does not intend
  • Any other conduct the Operator deems inappropriate

Article 7 (Suspension)

If you violate these Terms, the Operator may, without prior notice, suspend all or part of your use of the Service and delete your account.

Article 8 (Changes to and end of the Service)

The Operator may change the Service or end it without notifying users. If the Paid Plan is discontinued, users will be notified in advance, for example in the app.

Article 9 (Disclaimer)

The scope of the Operator's responsibility for the Service is set out in the separate Disclaimer. Except in cases of the Operator's intent or gross negligence, the Operator is not liable for damages arising from your use of the Service.

Article 10 (Changes to these Terms)

The Operator may change these Terms as needed. The changed Terms take effect when they are posted on this page.

Article 11 (Governing law and jurisdiction)

These Terms are governed by the laws of Japan. Any dispute regarding the Service shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance. However, if the laws of the country where you live provide otherwise, those laws apply.
