Terms of Service

Kakeifu – Family Timeline (English version) | Effective date: November 9, 2026

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

1. The Seller

HiBUNO, a sole proprietorship operated by Atsuhiko Miki, Kobe, Hyogo, Japan. Contact: hibuno2026@gmail.com. Full seller information is shown in our Refund Policy and Seller Information.

2. The App

  1. The App is a web application that lets you keep your family's memories (text, photos and voice recordings) on a shared family timeline. It runs in your web browser and can be added to your home screen.
  2. Your records are stored only on your own device. We do not receive, store or have access to your records.
  3. "Share with family", sold separately, lets you create a passphrase-protected file that up to three family members can view using viewer codes.

3. Purchase and license

  1. The App is sold for a one-time payment. There is no subscription.
  2. After payment, we will email you a purchase code within 3 business days (Japan time, excluding Japanese weekends and public holidays).
  3. We grant you a personal, non-exclusive, non-transferable license to use the App for your own and your family's non-commercial use. One purchase code may be used on up to 5 devices.
  4. You may not resell, transfer or publicly share your purchase code, or copy, modify or redistribute the App.

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. 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 records 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 App's backup feature. We cannot recover lost records.
  2. Please record information, photos and voice recordings about other people only with their permission.
  3. Please do not record passwords, PINs, Social Security numbers, card numbers or similar sensitive information.
  4. Keep your backup files and shared files safe, and share passphrases only with the people you intend.

7. Speech to type

The optional "Speak to type" feature uses your browser's speech recognition. Depending on your browser, your voice may be sent to the browser provider (such as Apple or Google) and handled under their terms and privacy policies.

8. Support

Support is available by email in Japanese only. You may write to us in English; we will reply in Japanese.

9. Disclaimer and limitation of liability

  1. We will make reasonable efforts to keep the App working, but we do not guarantee that it will work on every device or browser or be free of errors.
  2. The App is a tool for keeping family memories. It is not a substitute for a will, legal documents or medical, care or inheritance decisions.
  3. To the extent permitted by law, our total liability to you is limited to the amount you paid for the App, and we are not liable for the loss of records 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.

10. Changes and discontinuation

  1. We may improve or change the App. 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 App, we will announce it at least 6 months in advance, so that you have time to back up your records.

11. Governing law and jurisdiction

These Terms are governed by the laws of Japan. Any dispute relating to these Terms or the App 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.

12. 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.
