Terms of Service

*This English text is a reference translation. The Japanese version is the authoritative text; if there is any discrepancy in meaning between the Japanese and English versions, the Japanese version prevails.*

These Terms of Service (the "Terms") set out the conditions for using the file-transfer service "Mintfile" (the "Service") provided by X Inc. (the "Company", "we", "us" or "our"). Users use the Service on the condition that they agree to these Terms.

Article 1 (Application)

1. These Terms apply to all relationships between users and the Company concerning use of the Service.

2. Any usage rules, help pages, plan descriptions and other provisions that the Company posts on the Service (the "Individual Provisions") form part of these Terms. If an Individual Provision conflicts with these Terms, the Individual Provision prevails.

Article 2 (Definitions)

The terms used in these Terms have the following meanings.

  • "User" means any person who uses the Service (including both those who upload files and those who download files via a share link).
  • "Registered User" means a user who has completed the registration set out in Article 3.
  • "Paid Plan" means a plan the Company provides for a fee.
  • "Upload" means a user sending and storing files on the Service, and the set of stored files.
  • "Share Link" means the URL used to download uploaded files.
  • "Management Link" means the URL (including the management token) used to change the retention period, delete an Upload, and perform similar actions.

Article 3 (Registration)

1. Some features of the Service can be used without registration. For features that require registration, the user shall register using the method the Company specifies.

2. The Company may decline a registration application, or cancel a registration after approval, without any obligation to disclose its reasons, if it determines that the applicant:

  • has provided false information;
  • has previously breached these Terms; or
  • is otherwise not appropriate for registration in the Company's judgment.

3. A minor using the Service shall obtain the prior consent of their legal guardian.

Article 4 (Management of Account and Links)

1. Users shall manage, at their own responsibility, the email address and authentication links registered to their account, and the Share Links and Management Links.

2. Anyone who knows a Share Link can download the files of that Upload (except where a download password is set). Anyone who knows a Management Link can delete or otherwise operate that Upload. Users decide, at their own responsibility, the scope in which they share these links.

3. Except in the case of the Company's willful misconduct or gross negligence, the Company is not liable for any damage arising from an account or link being used by a third party.

Article 5 (Contents of the Service)

1. The Service is a file-transfer service that provides functions to upload files, issue Share Links, and download files.

2. The uploadable file size and number of files, the selectable retention periods, and other conditions differ by plan and are as displayed on the pricing page and elsewhere on the Service.

3. When the Service is used for free, advertisements may be displayed on the screen.

4. The Service is intended for the temporary transfer and sharing of files, and is not a service intended for long-term data storage (storage or backup).

Article 6 (Retention Period and Handling of Data)

1. Uploaded files are automatically deleted after the retention period selected by the user. Deleted files cannot be restored.

2. Users shall keep the originals (backups) of the files they upload at their own responsibility. Except in the case of the Company's willful misconduct or gross negligence, the Company is not liable for the loss, damage or leakage of files.

2. Unless a cancellation is completed before the end of the term, a Paid Plan renews automatically on the same conditions.

3. A user may cancel (stop the next renewal) at any time. Even if a user cancels partway through a contract term, fees already paid are not refunded and are not pro-rated, except where a refund is required by law.

4. Where there is reasonable cause, such as a change in economic conditions, the Company may revise the fees. Revised fees apply from the next renewal onward, after prior notice by posting on the Service or by other means.
