GRFR

Terms of Service

Effective date: August 1, 2026

These Terms of Service (these “Terms”) set out the conditions for using the macOS application “GRFR” (the “App”) provided by Takashi Nakao (the “Developer”). By downloading or using the App, you agree to these Terms.

1. Scope

  1. These Terms govern the rights and obligations between the Developer and you (the “User”) regarding use of the App.
  2. The App is distributed exclusively through the Mac App Store. Apple’s Media Services Terms and Conditions and the standard Licensed Application End User License Agreement also apply to your acquisition and use of the App. If these Terms conflict with Apple’s terms, Apple’s terms prevail.
  3. These Terms are concluded between the Developer and the User, not with Apple Inc. or its subsidiaries (“Apple”). However, Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

2. License

  1. The Developer grants you a non-transferable, non-exclusive license to use the App subject to these Terms and Apple’s terms.
  2. You may use the App on multiple Macs signed in with the same Apple Account, to the extent permitted by Apple’s terms.
  3. The App is licensed, not sold, to you.

3. Your Data

  1. All files that the App creates or edits based on your actions — including the catalog JSON file, the metadata JSON files placed next to your video files, and cover images — are your property. The Developer claims no rights whatsoever to these files or their contents.
  2. The App does not transmit your video files, metadata, or usage information to any external party. See the Privacy Policy for details.
  3. The metadata file format is a published specification. Nothing restricts you from viewing, editing, or migrating these files with tools other than the App. Reading and exporting your data is never restricted, whether or not you have made the in-app purchase.
  4. Based on your actions, the App creates and updates JSON files and image files in the same folder as your video files. You are responsible for backing up important data.

4. Purchases

  1. The App is free to download. Without the in-app purchase, you can register up to 99 videos. Apart from this limit on the number of videos, no feature is restricted.
  2. A one-time in-app purchase removes the registration limit.
  3. Even after reaching the limit, viewing, searching, playing, editing metadata for, and reading/writing the JSON files of already-registered videos are never restricted.
  4. All payment, billing, and refunds are handled by Apple. Refunds follow Apple’s standard policy and must be requested from Apple. The Developer cannot issue individual refunds.
  5. Purchases are tied to your Apple Account. On another Mac or a replacement Mac signed in with the same Apple Account, your purchase can be restored at no additional cost.

5. Prohibited Conduct

You must not:

  1. copy, redistribute, sell, rent, or sublicense the App;
  2. decompile, disassemble, or otherwise reverse engineer the App (except to the extent expressly permitted by applicable law);
  3. use the App for purposes that violate applicable laws or public order and morals; or
  4. infringe the intellectual property or other rights of the Developer or any third party.

6. Responsibility for Content

  1. The App is a tool for managing video files that you hold on local storage. It has no functions for acquiring, downloading, distributing, sharing, or copying content, and does not modify video files themselves.
  2. The App is provided to manage content that you have lawfully purchased or licensed, content for which you hold the copyright, or other content that you lawfully possess.
  3. You must not use the App to manage content that has been copied or distributed in infringement of copyright (commonly called pirated content), or other content that violates applicable laws.
  4. You are solely responsible for ensuring that your acquisition, possession, and use of files managed with the App are lawful.

7. Intellectual Property

  1. Copyright and all other intellectual property rights in the App belong to the Developer or its rightful owners.
  2. Notwithstanding the foregoing, the format (schema) of the metadata files the App reads and writes is a published specification, and third parties are not prevented from developing compatible tools.
  3. In the event of any third-party claim that the App infringes intellectual property rights, the Developer, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of such claim.

8. Maintenance and Support

  1. The Developer, not Apple, is solely responsible for maintenance and support of the App. Apple has no obligation whatsoever to furnish any maintenance or support services for the App.
  2. The Developer provides support to a reasonable extent via the contact listed in Section 15.
  3. The Developer does not guarantee the provision of updates or the continued availability of any particular feature.

9. Disclaimer and Limitation of Liability

  1. The App is provided “as is.” The Developer does not warrant that the App is free from defects in fact or in law (including, without limitation, defects in safety, reliability, accuracy, completeness, fitness for a particular purpose, or security, and errors, bugs, or infringements of rights).
  2. Except in cases of the Developer’s willful misconduct or gross negligence, the Developer is not liable for damages arising from special circumstances, or for lost profits, among the damages you incur arising from use of, or inability to use, the App.
  3. Where the Developer is liable for damages (except in cases of the Developer’s willful misconduct or gross negligence), its liability is limited to direct and ordinary damage actually incurred by you, up to the amount you paid for the App’s in-app purchase (or, if you have paid nothing, an amount equivalent to the then-current sales price of the App’s in-app purchase).
  4. The two preceding paragraphs do not apply to the extent not permitted under the Consumer Contract Act of Japan or other mandatory provisions of applicable law.
  5. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App (if any) to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App.
  6. The Developer, not Apple, is responsible for addressing any claims relating to the App or your possession or use of the App, including, but not limited to: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation.

You represent and warrant that:

  1. you are not located in a country that is subject to a United States Government embargo, or that has been designated by the United States Government as a “terrorist supporting” country; and
  2. you are not listed on any United States Government list of prohibited or restricted parties.

11. Changes to These Terms

  1. The Developer may amend these Terms without your individual consent, in accordance with Article 548-4 of the Civil Code of Japan, where:
    1. the amendment conforms to the general interest of Users; or
    2. the amendment is not contrary to the purpose of these Terms and is reasonable in light of the necessity of the amendment, the appropriateness of the amended content, and other circumstances pertaining to the amendment.
  2. When amending these Terms, the Developer will post the amended Terms and their effective date on this page a reasonable period before the effective date. For material changes, the Developer will also endeavor to give notice in the App or in App Store release notes.
  3. If you continue to use the App on or after the effective date of an amendment, the amended Terms apply to you.

12. Governing Law and Jurisdiction

  1. These Terms are governed by and construed in accordance with the laws of Japan.
  2. Any dispute arising in connection with the App or these Terms shall be subject to the exclusive jurisdiction of the Tokyo District Court (or the Tokyo Summary Court for cases within the jurisdiction of a summary court) as the court of first instance, except where mandatory consumer protection provisions or other applicable laws provide for the application of the law, or the jurisdiction of the courts, of your place of residence.

13. Severability

If any provision of these Terms, or any part of a provision, is held invalid or unenforceable under the Consumer Contract Act of Japan or any other applicable law, the remaining provisions of these Terms, and the remainder of any partially invalid or unenforceable provision, continue in full force and effect.

14. Language

The governing text of these Terms is the Japanese version (利用規約). This English version is provided for reference; if there is any discrepancy, the Japanese version prevails.
