Terms of Service

Tsunagu Family Treasure Box (English version) | Effective date: November 10, 2026

These Terms of Service ("Terms") apply to the purchase and use of Tsunagu Family Treasure Box (the "Note"), sold in U.S. dollars by HiBUNO (the "Seller", "we" or "us"). By purchasing or using the Note, you agree to these Terms.

1. The Seller

HiBUNO, a sole proprietorship operated by Atsuhiko Miki, Kobe, Hyogo, Japan. Contact: note@hibuno-life.jp. Full seller information is shown in our Refund Policy and Seller Information.

2. The Note

  1. The Note is a web application that helps you write down, one question at a time, what you want your family to know: your wishes, important information and memories. It runs in your web browser.
  2. Your entries, photos and voice recordings are stored only on your own device. They are not sent to our server, and we cannot see them.
  3. The free version lets you answer the first 3 questions (text only), with automatic saving and encrypted backup and restore.
  4. The full version includes all 17 questions, photos and voice recordings, encrypted backup and restore, printing and PDF output, and use without an internet connection.
  5. You can switch between Japanese and English at any time. What you have written is kept when you switch. What you wrote in the free version is carried over when you open the full version on the same device and in the same browser.

3. Purchase and license

  1. The full version is sold for a one-time payment. There is no subscription.
  2. Within 24 hours after payment, we will email you an activation link. The link can be used once, within 72 hours after it is issued. This is only the deadline for the link; it is not a limit on how long you can use the Note.
  3. We grant you a personal, non-exclusive, non-transferable license to use the Note for your own and your family's non-commercial use.
  4. You may not resell, transfer or share your activation link, or copy, modify or redistribute the Note.

4. Prices and payment

  1. Prices are shown in U.S. dollars on our sales page and at checkout. Any applicable taxes will be shown at checkout.
  2. Payments are processed by Stripe. For purchases from outside Japan, Stripe and its affiliates (including Link) may process your payment as a reseller and calculate and collect any applicable sales tax, VAT or GST. Your receipt may show Link as the seller. We do not receive your full card number.
  3. Any currency conversion or foreign transaction fees charged by your card company are your responsibility.

5. Refunds

Refunds are handled as described in our Refund Policy.

6. Your responsibilities

  1. Because your entries are stored only on your device, they may be lost if your device is lost or damaged or if you clear your browser data. Please make regular backups using the Note's encrypted backup feature. We cannot recover lost entries or forgotten backup passphrases.
  2. Please use a screen lock on your device. The Note's normal storage on your device is not protected by a separate password.
  3. Please record information, photos and voice recordings about other people only with their permission.
  4. Please do not record PINs, passwords, card numbers, Social Security numbers or similar sensitive information.

7. Support and updates

  1. For 30 days after purchase, we answer basic questions about how to use the Note by email (about 2 exchanges, 30 minutes in total).
  2. For 1 year after purchase, we provide updates and fixes so that the Note works in standard environments.
  3. Support is available in Japanese only. You may write to us in English; we will reply in Japanese.
  4. These periods do not limit any rights you have under the law.

8. Disclaimer and limitation of liability

  1. We will make reasonable efforts to keep the Note working, but we do not guarantee that it will work on every device or browser or be free of errors.
  2. The Note is a tool for organizing your thoughts and family conversations. It does not create a will, an advance directive or any other legal document, and it is not a substitute for advice from a lawyer, tax adviser or doctor.
  3. To the extent permitted by law, our total liability to you is limited to the amount you paid for the Note, and we are not liable for the loss of entries stored on your device. This does not limit liability for our intentional misconduct or gross negligence, or any rights you have under laws that cannot be excluded.

9. Changes and discontinuation

  1. We may improve or change the Note. If we change these Terms, we will post the new Terms on our website at least 30 days before they take effect.
  2. If we decide to discontinue the Note, we will announce it at least 90 days in advance and stop new sales at least 30 days before the end. We will help you export your entries, and we will never delete the entries on your device. A one-time purchase does not mean that we guarantee to operate the Note forever.

10. Governing law and jurisdiction

These Terms are governed by the laws of Japan. Any dispute relating to these Terms or the Note shall be subject to the exclusive jurisdiction of the Kobe District Court in the first instance, except where the laws of your country of residence give you a mandatory right to bring proceedings in your local courts.

11. Language

These Terms apply to purchases made in U.S. dollars. Purchases made in Japanese yen are governed by the Japanese-language terms of use.
