Terms of Service

This is an English reference translation of the Japanese Terms of Service, provided for users who display the app in English. The Japanese text is the only authoritative version. If the two differ, the Japanese text prevails. LinguaMile is currently offered in Japan only.

These Terms set out the conditions for using the language-learning app "LinguaMile" and its related services (the "Service") provided by the LinguaMile team ("we" or "us"). Please read these Terms before using the Service.

Article 1 Application and Agreement

  1. These Terms apply between us and everyone who uses the Service (a "User"). A contract for use of the Service under these Terms is formed when the User reviews these Terms and agrees to them in the manner we specify.
  2. Individual terms of use that we present separately form part of these Terms. Where they differ from these Terms, the individual terms prevail. Personal information and other User information is handled in accordance with our separate Privacy Policy and "Handling of Input Audio and Conversation Data".

Article 2 The Service

  1. The Service supports language learning through AI-based conversation, creation of learning materials, speaking and response practice, and saving and reviewing learning records.
  2. The available features, usage allowances, supported devices, supported languages and other details vary by plan and usage environment. Details are provided in the app or elsewhere. Device and data communication costs are borne by the User.

Article 3 Eligibility and Minors

  1. The Service is intended for people aged 13 or older.
  2. Users under 18 must obtain the consent of a parent or other legal guardian to these Terms and to the conditions of any paid service before using the Service. We confirm, in the manner we specify, that this consent has been obtained when use begins.
  3. Users must comply with applicable laws and with the terms of any external services they use.

Article 4 Accounts

  1. The Service is used by signing in with an external service we designate (such as a Google Account). A registration of the User on the Service (an "Account") is created at the first sign-in.
  2. Users must properly manage the external service account and the device used to sign in, and must not let any third party use them. Accounts cannot be transferred, lent or sold. If a User notices unauthorized use or a risk of it, the User must contact us promptly.

Article 5 AI Responses and Learning Results

  1. The Service may use AI for conversation, transcription, translation, pronunciation assessment, corrections, creation of learning materials and similar functions.
  2. Responses and assessments may contain errors, inaccurate content, inappropriate expressions or content that does not match the User's intent, and the same input may give different results. We do not guarantee any particular language ability, test result or other learning outcome.
  3. Before using generated content in real life, check its accuracy and appropriateness as needed. For medical, legal, financial or other professional judgments, consult an appropriate professional.

Article 6 Content Users Enter or Create

  1. When entering text, audio, source material or other content, or creating learning materials, Users must not infringe the copyright, privacy or other rights of any third party.
  2. Copyright and other rights in entered content belong to the User or to the third party that holds those rights, and are not transferred to us by these Terms.
  3. Users grant us, free of charge, permission to store, reproduce, adapt, transmit and otherwise use entered content, and to have our contractors (including external AI providers) process it, to the extent necessary to provide the Service. The specific handling is set out in the Privacy Policy and in "Handling of Input Audio and Conversation Data".
  4. The preceding paragraph does not include consent to use input audio or conversation data for product improvement or model training beyond what is necessary to provide the Service. If we make any such additional use, we will separately state its purpose and how to choose.
  5. Do not enter passwords, payment information, other people's confidential information or any other confidential information that does not need to be entered.

Article 7 Plans, Payment and Cancellation

  1. The Service has a free plan and paid plans. The features, usage allowances, prices including tax, contract periods and payment conditions are shown in the app or in the store of purchase before you apply. Purchases follow the procedures of the store.
  2. Paid plans renew automatically for each contract period shown at the time of application unless renewal is stopped.
  3. When a free trial is offered, the eligible users, the trial period, the price after the trial, automatic renewal and how to cancel are shown before you apply. After the trial ends, the User moves to the paid plan under the conditions shown.
  4. Stop automatic renewal in the store of purchase. Uninstalling the app or signing out alone does not stop it. The period of use and the price and timing that apply to a change are as shown at the time of purchase and in the store. When a paid plan ends, the User generally moves to the free plan.
  5. Cancellations and refunds after purchase follow the procedures of the store of purchase and the sales conditions shown. This does not limit any rights Users have under law.
  6. When we change plan contents or prices, we will notify Users in advance of the changes, when they apply and other necessary matters, and will follow the law and the conditions of the store of purchase.

Article 8 Usage Allowances and Credits

  1. The features covered by usage allowances, when allowances renew and whether they carry over are explained in the app or elsewhere. When we offer credits, how they are obtained, what they can be used for, how they are consumed and how long they are valid are shown before they are obtained or used.
  2. Operations for which the usage allowance or credits are insufficient follow the automatic consumption the User agreed to in advance, or the conditions confirmed at the time of the operation. We do not make purchases or change plans without the User's action or consent.
  3. Purchased credits cannot be exchanged for cash or transferred to a third party, except where we expressly state otherwise or where the law allows it. If a purchase is refunded or cancelled in the store, the unused portion of that purchase may become unusable.
  4. How usage allowances and credits are handled when provision fails or is interrupted follows the conditions shown before each feature is used and the applicable law.

Article 9 Prohibited Acts

Users must not violate laws or public order and morals; infringe the rights of third parties; impersonate others or use accounts without authorization; gain unauthorized access; exploit vulnerabilities; place excessive load on the Service; improperly circumvent usage allowances or billing restrictions; commit fraud, harassment or threats; commit any other illegal act through the Service; or commit any similar act that seriously interferes with third parties or the Service.

Article 10 Intellectual Property

  1. Rights in the programs, screens, logos, learning materials we provide and other content belong to us or to their rightful holders.
  2. Except where permitted by law or by the rights holder, Users may not reproduce, republish, sell or distribute them beyond what is necessary to use the Service.
  3. AI-generated output is handled in accordance with applicable law, the rights of third parties and any conditions we present separately.

Article 11 Restrictions on Use

  1. If there is a violation of these Terms, unauthorized use or another specific risk to safe provision of the Service, we may restrict use or suspend the Account to the extent necessary.
  2. Except in an emergency or where notice would be inappropriate, we will notify the User of the reason and the measure taken. Users may contact the desk in Article 16, and we will review the request and respond as needed.
  3. Paid plans, credits and refunds affected by such a measure are decided according to the individual circumstances, the conditions at the time of purchase and the applicable law.

Article 12 Changes, Interruption and Termination of the Service

  1. We may change the Service as needed for improvements, legal compliance, maintenance or other reasons. We may suspend all or part of the Service temporarily because of maintenance, failures, communication problems, outages of external services, disasters or other causes.
  2. Before making an important change, a long interruption or terminating the Service, we will give notice in the app, on the website or elsewhere with a reasonable period, except in an emergency. We will explain the effect on paid plans and purchased credits, any necessary refunds and other measures according to the circumstances and the applicable law.

Article 13 Leaving the Service and Deletion of Data

  1. Users may leave the Service through the procedure in the app or by contacting the desk in Article 16. Information after leaving is handled in accordance with the Privacy Policy and the conditions we present separately.
  2. Leaving the Service and cancelling in the store of purchase are separate procedures. To stop automatic renewal of a paid plan, complete the cancellation in the app or in the store.
  3. Usage allowances and credits on leaving are handled in accordance with the conditions presented before leaving and the applicable law.

Article 14 Our Responsibility

  1. We do not guarantee the accuracy, completeness, usefulness, fitness for a particular purpose or continued provision of the Service (including AI responses and assessments).
  2. We are not liable for damage that is not attributable to us (such as damage caused by outages of external services or the store of purchase, or by the communication environment).
  3. If a User suffers damage from our breach of obligation or tort, then, except in cases of our intent or gross negligence, compensation is limited to ordinary and direct damage actually suffered by the User, up to the amount the User paid for the Service in the 12 months before the date the cause of the damage arose (5,000 yen for Users who have made no payment).

Article 15 Changes to These Terms

We may change these Terms because of changes in law, changes to the Service or other circumstances.
