Ryo Tsuzukihashi (the "Operator") handles the information of users of the app "Mokumoku (Reading Bank)" (the "App") as follows.
1. Information stored only on your device
Recorded books (title, author, price, date and so on), books you want to read, reading notes, cover photos you take, the passbook holder name, the passbook design and the series you follow for new releases are stored on your device. Unless you use backup or the friends features, the Operator never receives them. The result of the age check made when you start the Bookshelf Features (whether you are 13 or over) is also kept only on your device and is never sent to the Operator.
2. Information kept when you create an account
- The identifier received when you sign in with your Apple ID or Google account, and your email address (a relay address if you choose Apple's "Hide My Email"). If you connect both, the identifiers of both. If you start as a guest, an anonymous user ID
- The name and comment on your bookshelf, your friend code, and who can see your bookshelf
- The books on your bookshelf (title, author, ISBN and cover image URL) and your comment on each
- Your friends list, friend requests, the books and messages sent or received as recommendations, the bookshelves you add to your favorites, the users you block (with their name at the time), and the reports you send (including where you reported from and the bookshelf name, comment or recommendation message at the time)
- The date and time you agreed to the bookshelf rules
- The device ID used to deliver notifications (Firebase installation ID), the device type (iOS or Android) and language
- If you subscribe to the paid plan, the records, reading notes and cover photos kept for backup
These are stored and processed in Firebase (Authentication, Cloud Firestore, Cloud Storage, Cloud Functions and Cloud Messaging) provided by Google LLC.
3. Purposes of use
- To back up and restore your data when you change devices
- To show your bookshelf to friends or everyone, and to deliver recommendations between friends
- To notify you when someone adds your bookshelf to their favorites, and when books are added to a bookshelf in your favorites
- To review reports and keep the Bookshelf Features safe
- To check the purchase status of the paid plan
- To answer inquiries and respond to misuse
- To learn which screens and features are used, so that we can improve the App
4. Information shown to friends
The books and comments on your bookshelf are shown to the users in the range you choose (friends only or public). If you make it public, anyone who uses the app can see it, it is listed in the Everyone list, and it may be found by name. The name and comment on your bookshelf and the number of books are also shown to your friends, users you exchange friend requests with, and people who know your friend code. Amounts, reading notes, record dates and your email address are never shown to other users. Books and messages you send as recommendations are shown to the recipient. The number of favorites on a bookshelf is shown to people who can see the bookshelf. Who added it to their favorites is notified only to the owner of the bookshelf.
5. Information sent to external services
The App uses the following external services. The information sent to each service and each company's privacy policy are as follows.
- Book lookups and new release checks: openBD, Google Books, the National Diet Library Search, Kakao and open data from the National Central Library of Taiwan (imported into the Operator's Firebase) (we send ISBNs, search terms and series names; no information that identifies you is sent)
- Currency conversion: Firebase Remote Config (receives reference rates to convert Japanese list prices into won or New Taiwan dollars; a Firebase installation ID is used, and no information that identifies you reaches the Operator)
- Payments: RevenueCat (purchase records and an anonymous user ID issued by the App) https://www.revenuecat.com/privacy
- Accounts and backup: Firebase (Google LLC) https://firebase.google.com/support/privacy
- Preventing unauthorized access: Firebase App Check (uses Apple's App Attest on iPhone and iPad, and Google's Play Integrity on Android, to confirm that requests come from the genuine App; no information that identifies you reaches the Operator)
- Usage analytics: Google Analytics for Firebase (Google LLC) (the screens you open, the type and result of actions such as recording or searching books, a rough range of your book count, device and app information, approximate region, and the app instance ID; on Android, also the advertising ID. We do not send book titles, authors, ISBNs, search words, the contents of reading notes, or email addresses) https://policies.google.com/technologies/partner-sites
The App does not show advertising. Usage analytics are used only to improve the App.
6. Links to bookstores
When you open a bookstore's page from the App, that store may collect information on its own, for example with cookies. How that information is handled is governed by each store's privacy policy.
The App's links to Amazon and Rakuten Books are Amazon Associates Program and Rakuten Affiliate links. When a book is purchased through such a link, the Operator may receive a referral fee. No information that identifies who made the purchase reaches the Operator.
7. About this website

8. Provision to third parties
Except as required by law, the Operator does not provide personal information to third parties without your consent.
9. Retention and deletion
When you delete your account, the information stored on the Operator's servers (including your bookshelf, friends, friend requests, recommendations, favorites and notification device IDs) is deleted. Reports received may be kept to deal with misuse. When the paid plan ends, the backup is deleted 7 days later. Information on your device is removed when you delete the App.
10. Security
The Operator takes appropriate measures, such as restricting access, to prevent unauthorized access to, leakage of or tampering with the information it keeps.
