These Terms of Service (the “Terms”) set forth the conditions for the use of the application “PHRAZE” (the “App”) provided by Takuma Okuyama (the “Provider”). By using the App, users are deemed to have agreed to these Terms.

Article 1 (Application)

These Terms apply to all relationships between the user and the Provider in connection with the use of the App.

Article 2 (Registration)

   1. There is false information in the registration data.
   2. The applicant has previously had their registration terminated due to violation of these Terms or similar reasons.
   3. The applicant falls under antisocial forces (including organized crime groups, members or quasi-members thereof, affiliated enterprises of organized crime groups, corporate racketeers, groups engaging in social-movement-related racketeering, and any other persons equivalent thereto; hereinafter the same) or has a close relationship therewith.
   4. The Provider otherwise judges registration to be inappropriate.

Article 4 (Fees and Payment)

2. Subscriptions are automatically renewed at the end of each billing period unless canceled. To stop the automatic renewal, the user shall use the iOS “Settings” → “Apple ID” → “Subscriptions” menu.
3. Handling of cancellation, refunds, and other payment matters is subject to the terms and conditions of the Apple App Store. Except where a refund has been approved by Apple in accordance with such terms, the Provider does not refund fees already paid.
4. The Provider may change the content, fees, billing period, and scope of paid features. When raising the fees, except in urgent and unavoidable cases, the Provider will endeavor to notify users in advance—as a guideline, at least 30 days before the effective date—by in-app notification, email to the registered address, or other appropriate means. In addition, the Provider will notify users in advance in accordance with the procedures prescribed by Apple, and users will be given an opportunity to opt out of such fee increase in the manner prescribed by Apple.
5. The content, applicable conditions, and duration of any free trial period or promotional grant shall be as displayed within the App and as separately notified by the Provider.

Article 5 (Prohibited Acts)

The user shall not engage in any of the following acts when using the App.

4. Acts that interfere with the operation of the App.
5. Unauthorized access or attempts at unauthorized access.
6. Acts of impersonating other users or third parties.
7. Reverse engineering, decompiling, disassembling, or otherwise analyzing the source code of the App; provided, however, that this shall not apply to the extent expressly permitted by applicable laws.

9. Using information obtained through the App beyond its intended purpose.
10. Commercial use of all or part of the App without the Provider’s prior written consent.

The Provider may suspend or interrupt the provision of all or part of the App without prior notice to users in any of the following cases.

1. Maintenance, inspection, or updating of the App’s systems.
2. Force majeure such as earthquake, lightning, fire, power outage, or natural disaster makes provision difficult.
3. Computers or communication lines cease to function due to accident.
4. The Provider otherwise judges that provision of the App is difficult.

The Provider shall not be liable for any disadvantage or damage suffered by users or third parties due to suspension or interruption under this Article.

Article 7 (Use Restrictions and Account Termination)

The Provider may restrict use of all or part of the App or terminate the account if the user falls under any of the following cases.

Where any of the events set forth in the preceding paragraph applies, the Provider shall, in principle, endeavor to give the user an opportunity to cure such breach. However, where Item 1, Item 2 or Item 6 applies, or where any other material breach is reasonably found to exist, the Provider may impose use restrictions or terminate the account without prior notice.

The Provider shall not be liable for any damages incurred by users due to acts under this Article.

Article 8 (Account Closure / Account Deletion)

1. The user may delete their account and discontinue use of the App at any time.
2. Account deletion may be performed by either of the following methods.
   1. The “Delete Account” feature on the App’s settings screen (executed immediately; the recommended method).
   2. Via the contact set forth in Article 9 of the separately established Privacy Policy (for requests by a third party, requests concerning users under the age of 13, complete erasure including third-party analytics services, etc.).
3. Upon account deletion, the following information managed by the Provider is erased or pseudonymized (see Article 6 of the Privacy Policy for details).
   1. Immediately erased: learning data, billing principal ID, subscription status, and monthly usage.
   2. Retained in pseudonymized form: usage event logs (13 months) and third-party analytics service identifiers (retained while pseudonymized).
   3. Retained for legal compliance: account deletion requests / audit logs (1 year).
   4. Retained to prevent fraudulent revival: the pseudonymized HMAC of deleted identifiers (indefinite), etc.
4. Even after account deletion, the automatic renewal of paid subscriptions purchased through the Apple App Store continues. To stop automatic renewal, the user must separately do so via iOS “Settings” → your Apple ID → “Subscriptions” (the App’s account deletion screen also provides guidance on this). Refunds for paid subscriptions after account closure are subject to the terms and conditions of the Apple App Store.
5. After account deletion is complete, if the user uses the App again on the same device, a new account is created as an anonymous user. The learning data, subscriptions, and billing history of the previous account cannot be restored.
6. If a network failure or similar event occurs during account deletion processing, the App automatically resumes the deletion processing at the next launch. If the deletion cannot be resumed and this state persists, the user may contact the support contact provided within the App.

Article 9 (Disclaimer and Limitation of Liability)

1. The Provider makes no representations or warranties, express or implied, that the App is free from defects, whether of fact or law (including, without limitation, defects, errors, bugs, infringements, etc., regarding safety, reliability, accuracy, completeness, validity, fitness for a particular purpose, or security). Furthermore, the Provider does not warrant that the user will obtain any particular learning outcome expected by the user (such as improvement of English proficiency) from the use of the App.
2. The Provider shall not be liable for any damages caused to users arising from the App, except in cases of the Provider’s willful misconduct or gross negligence.
3. Notwithstanding the preceding paragraph, the Provider’s liability for damages caused by its ordinary (non-gross) negligence shall be limited to the total amount paid by the user to the Provider during the twelve-month period preceding the occurrence of the damage. However, this limitation shall not apply to damages caused by the Provider’s willful misconduct or gross negligence, damages to the user’s life or body, or any other damages for which limitation of liability is not permitted under applicable laws.

Article 10 (Handling of Generated Content)

1. The App provides features to generate content such as learning phrases, conversational examples, and explanations using AI technology.
2. The App generates content probabilistically using generative AI (artificial intelligence), and even for identical or similar inputs, different content may be output each time it is generated. The App also uses generative AI provided by a third party (Google LLC’s Gemini / Vertex AI) in providing its features (details of the data transmitted are set forth in Article 5 of the Privacy Policy). Due to the nature of these technologies, generated content may contain inaccurate, inappropriate, or contextually unsuitable material (including so-called “hallucinations,” in which non-existent facts, sources, citations, and the like are generated in a plausible-looking form). The Provider makes no warranty whatsoever regarding the accuracy, appropriateness, usefulness, or non-infringement of third-party rights of generated content.
3. The user shall judge the use of generated content at the user’s own responsibility, and shall, on the user’s own behalf, verify the accuracy and appropriateness of the content before use, especially for important purposes such as business documents, public situations, or transmission to third parties.
4. The Provider shall not be liable for any damages caused to users or third parties as a result of the use or consequences of generated content.
5. To the extent permitted by applicable laws, the copyright and other intellectual property rights in the generated content shall belong to the user. Provided, however, that the Provider may use the generated content for internal analysis on an anonymized basis, solely to the extent necessary for the purposes of improving service quality, preventing unauthorized use, and enhancing features.
6. Users acknowledge that generated content may infringe the copyrights or other rights of third parties, and shall, on the user’s own responsibility, verify the absence of such infringement before any commercial use or public disclosure of the generated content.
7. Due to the nature of machine learning, generated content may be identical or similar to content generated for other users, and the Provider does not warrant that such content belongs exclusively to any particular user.
8. Generated content is provided for general informational and learning-reference purposes, and does not constitute advice on legal, medical/health, tax, accounting, financial/investment, or other professional matters, nor is it a substitute for advice from a qualified professional. Where a professional judgment is required, the user shall consult a qualified professional rather than relying on the generated content.
9. The user represents and warrants that the user has the lawful and proper authority to use, in the App, any information the user inputs into the App (including themes, text, and prompts), and that such input does not violate any laws, these Terms, or the intellectual property rights, privacy, or other rights of any third party. The user shall not, without proper grounds, input the personal information or other sensitive information of any third party, and shall be responsible for any damage caused to the Provider or any third party arising from the information the user has input.

Article 11 (Intellectual Property)

1. All intellectual property rights related to the App (copyrights, trademarks, design rights, patents, etc.) belong to the Provider or the relevant third parties.
2. The user shall not use the intellectual property of the Provider or third parties beyond the license to use the App under these Terms.

Article 12 (Change or Termination of Service)

1. The Provider may change, add to, or terminate the content of the App.
2. For changes that materially disadvantage users, or for the termination of all or any material part of the App, the Provider will notify users at least 30 days prior to the effective date through in-App notification or other appropriate means.
3. If the App is terminated in whole or in any material part while any unused portion of a paid subscription remains, the Provider will provide pro-rata refunds or equivalent measures within the scope permitted by the procedures prescribed by the Apple App Store.
4. The Provider shall not be liable for any damages caused to users due to the change or termination of the App, beyond the scope set forth in Article 9.

Article 13 (Changes to These Terms)

1. The Provider may modify these Terms as standard form contracts (Article 548-2, Paragraph 1 of the Civil Code of Japan) in any of the following cases.
   1. The modification of these Terms conforms to the general interests of the users.
   2. The modification of these Terms does not contradict the purpose for which the contract was made and is reasonable in light of the necessity of the modification, the appropriateness of the modified content, the substance of the modification, and other circumstances pertaining to the modification.
2. When modifying these Terms, the Provider will give notice of the content of the modified Terms, the effective date thereof, and the reason for the modification, at least 30 days prior to the effective date, through in-App notification, publication on the Provider’s official website, or other appropriate means. Provided, however, that for minor modifications that conform to the general interests of users, notice given concurrently with the effective date shall suffice.
3. If a user continues to use the App on or after the effective date of the modification, such user shall be deemed to have agreed to the modified Terms.

Article 14 (Handling of Personal Information)

The Provider shall appropriately handle users’ personal information acquired in connection with the use of the App in accordance with the separately established “Privacy Policy”. The Privacy Policy, together with these Terms, constitutes the terms and conditions for the use of the App.

Article 15 (Governing Law and Jurisdiction)

1. These Terms shall be interpreted in accordance with the laws of Japan as the governing law.
2. In the event of any dispute between the Provider and the user regarding the App, the Saitama District Court shall be the exclusive jurisdiction of the court of first instance, as agreed between the parties. Provided, however, that where the user qualifies as a consumer under the Consumer Contract Act of Japan, these Terms shall not preclude the application of the special provisions regarding jurisdiction over consumer contracts under the Code of Civil Procedure (including Article 3-7, Paragraph 5 thereof), and the district court or summary court having jurisdiction over the user’s address may also serve as a court of jurisdiction.

Article 16 (General Provisions)

1. No assignment: The user shall not assign, transfer, pledge, or otherwise dispose of the user’s status, rights, or obligations under these Terms to any third party without the Provider’s prior written consent. In the event the Provider transfers its business relating to the App to a third party, the Provider may transfer to the transferee, in connection with such business transfer, the Provider’s status under these Terms and the user’s registration information and other personal information.
2. Severability: Even if any provision or part of these Terms is determined to be invalid or unenforceable under the Consumer Contract Act or other applicable laws, the remaining provisions of these Terms shall continue in full force and effect.
3. Entire agreement: These Terms constitute the entire agreement between the Provider and the user with respect to the matters set forth in these Terms, and except where there is a separate agreement between the Provider and the user regarding matters not expressly set forth in these Terms, any prior agreements, representations, or understandings inconsistent with these Terms shall be superseded by these Terms.
4. Notices: Notices from the Provider to the user shall be given by means of in-App notification, email to the registered email address, publication on the Provider’s official website, or any other method that the Provider deems appropriate.
5. Indemnification: If the user violates these Terms or causes any damage to the Provider in connection with the user’s use of the App (including costs incurred in responding to claims from third parties and reasonable attorneys’ fees), the user shall compensate the Provider for such damage.

Article 17 (Special Provisions Concerning the Apple App Store)

The App is distributed through the Apple App Store. With respect to those parts of these Terms that concern the license to use the App, the user and the Provider confirm the following. To the extent any provision of this Article conflicts with any other provision of these Terms, this Article shall prevail insofar as it concerns the license to use the App distributed through the Apple App Store.

1. Parties to these Terms: These Terms are concluded solely between the user and the Provider, and not with Apple Inc. (“Apple”). The Provider, not Apple, is responsible for the App and the content thereof.
2. Scope of License: The license granted by the Provider to the user is limited to a non-transferable license to use the App on any Apple-branded products that the user owns or controls, as permitted by the Usage Rules set forth in the Apple Media Services Terms and Conditions.

Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the App.
4. Warranty: The Provider is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, the user may notify Apple, and Apple will refund the purchase price for the App to the user. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty will be the sole responsibility of the Provider.
5. Product Claims: The Provider and the user acknowledge that the Provider, not Apple, is responsible for addressing any claims of the user or any third party relating to the App or the user’s possession and/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 or similar legislation.
6. Intellectual Property Rights: In the event of any third-party claim that the App or the user’s possession and use of the App infringes that third party’s intellectual property rights, the Provider, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
7. Legal Compliance: The user represents and warrants that (i) the user is not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) the user is not listed on any U.S. Government list of prohibited or restricted parties.
8. Provider Name and Contact: Any questions, complaints, or claims of the user with respect to the App shall be directed to the following.
   • Provider: Takuma Okuyama
   • Address: Disclosed without delay upon request (please use the contact below).
   • Contact: [email protected]
9. Compliance with Third Party Terms: The user must comply with applicable third party terms of agreement when using the App.
10. Third Party Beneficiary: Apple and Apple’s subsidiaries are third party beneficiaries of these Terms, including this Article, and, upon the user’s acceptance of these Terms, Apple will have the right to enforce these Terms (insofar as they concern Apple as a third party beneficiary) against the user.
