Last updated: August 10, 2026

This is a reference translation provided for convenience. The Japanese version is the legally binding original. If the two differ, the Japanese version governs.

These Terms of Service (the "Terms") set out the conditions of use for the WordPress plugin "Sorabun" and the related services (collectively, the "Service") provided by PR Elle LLC (合同会社 PR Elle) (the "Company"). Customers who use the Service (each, a "User") are deemed to have agreed to these Terms.

Article 1 (Application)

  1. These Terms apply to all dealings between the Company and Users in connection with use of the Service.
  2. Individual explanations, FAQs, documentation, and other materials that the Company publishes on the Service form part of these Terms.
  3. Where the provisions of these Terms differ from the content of an individual explanation, the individual explanation shall govern.

Article 2 (Definitions)

Article 3 (Scope of License)

  1. The program portion of the Plugin is provided under the GNU General Public License v2 or later (GPL-2.0-or-later). The rights that license grants to a User are not restricted by these Terms.
  2. Notwithstanding the preceding paragraph, what the Company provides for a fee is the issuance of License Keys, the delivery of updates, and the provision of user support. A User may receive these on the number of Target Sites set out for the plan the User purchased.
  3. The number of Target Sites for each plan is as follows.
    • Personal: 1 site
    • Pro: 3 sites
    • Agency: 20 sites
    • Lifetime (one-time purchase): 1 site
  4. Only under the Agency plan may a User install the Plugin on sites belonging to clients whose sites the User has been engaged to build and operate.
  5. A License Key may not be sold, lent, shared, or otherwise provided to a third party by any means.
  6. The Lifetime (one-time purchase) plan includes the provision of updates for one year from the date of purchase. Use of the plugin may continue after that one year has elapsed, but receiving further updates and support after that point requires the separate purchase of a renewal license.

Article 4 (Management of Accounts and License Keys)

  1. Users shall manage their own account credentials and License Keys at their own responsibility.
  2. A User bears responsibility for any damage arising from inadequate management of credentials or a License Key, errors in their use, or use by a third party, and the Company bears no responsibility whatsoever for such damage.
  3. A User may change the site to which a license applies by deauthorizing a Target Site from My Page.

Article 5 (Fees and Payment Method)

  1. Fees for use of the Service are as set out on the pricing page of the Company's website and in the "Notice under the Specified Commercial Transactions Act."
  2. The payment method is credit card payment, using Stripe, Inc. (and its Japanese corporate entity) as the payment processor. Card information is obtained and processed directly by that company, and the Company does not retain card numbers.
  3. Campaign pricing such as first-month discounts and annual-payment discounts is applied in accordance with the conditions displayed on the Company's website.
  4. Communication charges necessary for use of the Service, and fees for use of External AI Services, are not included in the usage fee and are borne by the User.

Article 6 (Contract Term, Automatic Renewal, and Cancellation)

  1. The monthly-payment plan and the annual-payment plan renew automatically every month and every year, respectively.
  2. A User may stop the next renewal (cancel) at any time via My Page or by a method the Company otherwise prescribes.
  3. Even after completing the cancellation procedure, a User may continue to use the Service through the end of the period already paid for. The License Key becomes invalid once that period has elapsed.
  4. If the cancellation procedure is not completed by the day before the next renewal date, the contract renews automatically and the fee for the renewal period is charged.

Article 7 (Returns and Refunds)

  1. Because the Service consists of the provision of digital content, and provision is complete upon issuance of the License Key, the Company cannot accommodate returns or refunds requested for a User's own convenience.
  2. Notwithstanding the preceding paragraph, if the Service becomes entirely unusable for a substantial period due to a cause attributable to the Company, the Company will discuss its response on an individual basis.
  3. Disadvantages arising from the suspension of an External AI Service, changes to its specifications, revisions to its pricing, or other causes not attributable to the Company are not eligible for a refund.

Article 8 (Use of External APIs and Cost Burden)

  1. The Plugin's functions such as article generation, image generation, speech synthesis, and retrieval of search rankings operate using API keys for External AI Services that the User has personally obtained.
  2. Fees for use of External AI Services shall be paid by the User directly to each provider, and the Company bears no responsibility whatsoever for such costs.
  3. A User shall comply with the respective terms of use of each External AI Service.
  4. Some functions of the Plugin may become unusable due to changes to the specifications of an External AI Service, discontinuation of its provision, revisions to its pricing, fluctuations in response quality, or similar causes. The Company will respond to the extent possible but does not guarantee the outcome.

Article 9 (Handling of Generated Content)

  1. Ownership of rights in Generated Content, and the conditions under which it may be used, are governed by the respective terms of use of the External AI Service the User employed.
  2. The Company asserts no right whatsoever in Generated Content.
  3. No guarantee whatsoever is given as to the accuracy, completeness, currency, or usefulness of Generated Content, or that it does not infringe the rights of any third party. A User is responsible for personally reviewing the content and verifying the underlying facts before publishing it.
  4. If a dispute with a third party arises from the publication or use of Generated Content, the User shall resolve it at the User's own responsibility and expense, and if the Company incurs damage as a result, the User shall compensate the Company for it.
  5. In publishing Generated Content, a User shall comply with the Copyright Act, the Act on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices (the "Pharmaceutical and Medical Device Act"), the Act against Unjustifiable Premiums and Misleading Representations, and other applicable laws and regulations, as well as the guidelines of each search engine and each distribution platform.

    • When a computer or communication line stops due to an accident
    • Any other case in which the Company determines that continued provision is difficult
  3. The Company may end the provision of the Service by giving Users at least three months' notice. In this case, the Company will refund to Users of the annual-payment plan or the Lifetime (one-time purchase) plan the amount corresponding to the unexpired portion of the period, calculated on a pro-rata basis.

Article 12 (Disclaimer of Warranties and Exemption from Liability)

  1. The Company does not warrant, whether expressly or impliedly, that the Service is suited to a User's particular purpose, that it has the functions, accuracy, or usefulness the User expects, that no malfunction will occur in the User's environment, or that results such as improved search rankings or other outcomes will be obtained.
