日本語

These Terms of Use (the "Terms") set out the conditions for using the iOS app "The Simple Fit" (the "App") provided by Hodokeru (operator: Yuki Yamashita; "we" or "us"). By using the App, you ("you" or the "User") agree to these Terms.

1. Scope

  1. These Terms apply to all relationships between you and us regarding the use of the App.
  2. The license to use the App distributed through the App Store is also governed by Apple Inc.'s standard Licensed Application End User License Agreement. These Terms supplement it.

2. What the App Does

  1. The App lets you store and view, on your own device, the sizes of people, the dimensions of places and things, and related notes that you enter by hand.
  2. The App has no account registration or sign-in. We do not receive or store anything you enter.
  3. All information stored in the App is based on your own input, and we are not responsible for its accuracy.
  4. If you are a minor, you must obtain the consent of a parent or legal guardian before using the App or purchasing the Full Version.

3. Estimates such as "Will it fit?"

  1. "Will it fit?" compares the width, depth, and height you enter as numbers and shows a rough estimate. It does not guarantee that an item will actually fit, or that it can be carried in or installed.
  2. Whether an item can actually be carried in or installed depends on its shape, orientation, tilting, the path it must pass through, packaging, and more. Please base purchase and delivery decisions on your own checks.
  3. Except as provided in Section 8, we are not liable for any damage arising from relying on these estimates, including when a purchased item does not fit.

4. Prohibited Conduct

When using the App, you must not:

  • Violate laws or public order and morals
  • Engage in conduct related to criminal acts
  • Infringe the rights or interests of us or any third party
  • Modify, decompile, or otherwise reverse engineer the App (except as permitted by law)
  • Interfere with the operation of the App
  • Engage in any other conduct we reasonably consider inappropriate

5. Pricing

  1. The App can be used free of charge up to a certain limit. The free limit is shown in the App.
  2. To register beyond the free limit, you need to purchase the one-time "Full Version" through in-app purchase (the "Full Version"). The price is shown on the purchase screen in the App. The Full Version is a single purchase with no recurring charges.
  3. Even without purchasing the Full Version, you can continue to view, edit, and delete what you have already registered, and export or import backups.
  4. Purchases, restoration, and refunds of the Full Version follow the App Store terms and procedures set by Apple Inc. With the same Apple Account, you can restore your purchase after changing devices or reinstalling by tapping "購入を復元" (Restore Purchases) in the App's settings.
  5. We may change the free limit, or the content and price of the Full Version. However, we will not narrow what a User who has already purchased the Full Version can do compared with the time of purchase.

6. Data

  1. Information stored in the App is handled in accordance with our separate Privacy Policy.
  2. Data in the App is stored only on your device, and we do not keep a copy. If data is lost because your device fails, is lost or reset, or the App is deleted, we cannot restore it.
  3. You are responsible for backing up your data as needed, for example with the App's "ファイルに書き出す" (Export to a file) feature. Exported files are under your control, and you are responsible for storing, sharing, and deleting them.
  4. Importing a backup file replaces all current data on the device with the imported contents.

7. Suspension of the App

  1. We may suspend or interrupt all or part of the App (including distribution on the App Store and delivery of updates) without prior notice if we determine that:
    • Maintenance or updates of the App are required
    • Providing the App has become difficult due to earthquakes, power outages, or other force majeure
    • Providing the App has otherwise become difficult
  2. Except as provided in Section 8, we are not liable for any damage caused by such suspension or interruption.

8. Disclaimer

  1. We make no express or implied warranty that the App is free from factual or legal defects.
  2. Except in cases of our willful misconduct or gross negligence, we are liable for loss of data or other damage arising from the use of the App only to the extent set out in the following paragraph.
  3. In the cases described in the preceding paragraph (excluding our willful misconduct or gross negligence), our liability is limited to the total amount you have paid us in connection with the App.

9. Changes to or Termination of the App

We may change the content of the App without notice to you, and we may stop providing the App. If we stop providing the App, we will endeavor to give advance notice on this page or by other appropriate means. Except as provided in Section 8, we are not liable for any damage resulting from this.

10. Intellectual Property

All intellectual property rights in the App and related content (including images, text, and design) belong to us or the rightful owners. Rights to the content you enter in the App belong to you.

11. Changes to These Terms

  1. We may change these Terms when we consider it necessary.
  2. We will announce significant changes on this page or by other appropriate means. Revised Terms take effect when they are posted on this page.

12. Governing Law and Jurisdiction

  1. These Terms are governed by the laws of Japan.
  2. Any dispute relating to the App shall be subject to the exclusive jurisdiction of the court having jurisdiction over our location.
  3. These Terms are written in Japanese and English. If there is any discrepancy between the two, the Japanese version prevails.
