7. "Legal representative" means the parent or legal guardian of a student who is a minor.
8. "Learning records" means all records generated through use of the Service, including reading level (Lexile measure), book progress, quiz results, Read Aloud recordings and their assessment results.
9. "AI features" means features provided using artificial-intelligence technology, including automated pronunciation and fluency assessment, reading-level determination, learning-summary generation and question generation.

(2) Terms not defined here have the meaning given by applicable law and ordinary commercial practice.

(1) The Company publishes these Terms on the Service so that users can readily review them.

(2) The Company may amend these Terms to the extent that the amendment does not contravene the Act on the Regulation of Terms and Conditions, the Act on Consumer Protection in Electronic Commerce, the Personal Information Protection Act or other applicable law.

(3) The Company will give notice of any amendment, stating the effective date and the reason, at least 7 days before it takes effect. Where the amendment is unfavourable to users or otherwise material, notice will be given at least 30 days in advance and, for Institutions and paying users, individually by email.

(4) Where the Company has clearly stated in that notice that failure to object by the effective date will be treated as acceptance, a user who does not expressly object is deemed to have accepted the amended Terms. A user who does not accept them may terminate their agreement.

(1) The Service comprises:

• a levelled English book library and book recommendations based on reading level (Lexile measure);
• native-speaker audio (speech synthesis) with sentence and word highlighting;
• Read Aloud practice with AI pronunciation and fluency assessment;
• comprehension quizzes, vocabulary and comprehension activities, and result reports;
• course and assignment management and progress dashboards for teachers and institution administrators;
• authoring tools for textbooks, workbooks, slides and curriculum plans; and
• any further services the Company develops or provides through partnerships.

(2) The specific features and usage limits available depend on the plan contracted for. The Company publishes the scope of each plan on the Service or in the applicable agreement.

(1) An institutional agreement is formed when the Institution and the Company sign an agreement or order form, or when an institution administrator completes the sign-up process and the Company accepts it.

(2) An individual agreement is formed when a user applies for the Service having agreed to these Terms and the Privacy Policy, and the Company accepts the application.

(3) The Company may refuse an application, or subsequently terminate the agreement, where:

• the applicant has used another person’s identity or supplied false information;
• a child under 14 has applied without the consent of their legal representative;
• the applicant has previously had an agreement terminated for breach of these Terms; or
• there is a technical or operational impediment to providing the Service.

(1) Institution-managed students sign in using a School Code, a Student ID and a PIN.

(2) Institution administrators and teachers sign in using an email address and password or a linked external account.

(3) Responsibility for safeguarding accounts and credentials rests with the user to whom they were issued and with their Institution. Credentials must not be transferred, lent or shared.

(5) A user who becomes aware that their account has been compromised or is being used by a third party must notify the Company immediately and follow its instructions. The Company is not liable for loss arising from a failure to notify.

(1) Where the Company processes the personal information of a child under 14, it obtains the consent of the child’s legal representative in accordance with Article 22-2 of the Personal Information Protection Act, collecting from the legal representative the minimum information necessary to verify that consent.

(2) For institution-managed student accounts, the Institution must obtain consent from the legal representative to use of the Service and to the processing of personal information before creating the account, and warrants to the Company that it has lawfully obtained that consent.

(3) For individual student accounts opened directly by a legal representative, the Company verifies the legal representative’s consent during account creation, and use of the Service may be restricted until that verification is complete.

(4) A legal representative may at any time request access to, correction, deletion or suspension of processing of the child’s personal information, or withdraw consent. The Privacy Policy sets out the procedure.

(2) The Company processes student personal information only within the scope of the Institution’s documented instructions and of these Terms and the Privacy Policy. Where the Company considers an instruction to be contrary to applicable law, it will notify the Institution without delay and may suspend the processing concerned.

(3) The Institution is responsible for the creation, modification, deletion and permissioning of its teacher and student accounts, and must promptly deactivate accounts of users who cease to be eligible through departure, transfer or graduation.

(4) On termination of an institutional agreement the Company will, at the Institution’s election, return or destroy the learning records, and will destroy them if no instruction is received within 90 days of termination.

(5) Where a student or legal representative makes a request directly to the Company, the Company will pass it to the Institution without delay and act on the Institution’s instructions, except where applicable law requires the Company to respond directly.

(1) The Service is offered on free and paid plans. Fees, usage limits and billing cycles are as published on the Service or set out in the applicable agreement.

(2) Institutional fees are payable by the method set out in the applicable agreement or order form.

(3) Individual fees are payable in advance through the payment methods offered by the Company. Where a payment processor is used, that processor’s terms also apply.

(4) The Company may change its fees, with effect from the billing cycle following the change. Notice will be given at least 30 days before the effective date, and individually to Institutions and paying users.

(5) If fees are not paid when due, the Company may suspend the Service or terminate the agreement after demanding payment within a reasonable period.

(1) Individual users may withdraw their subscription within 7 days of the date the agreement is formed or the Service becomes available, in accordance with the Act on Consumer Protection in Electronic Commerce.

(2) Withdrawal may be restricted once the user has begun using the content. Even then, withdrawal remains available for any divisible portion of the content not yet used; the Company will disclose any such restriction in advance and take measures such as providing trial access.

(3) Where a user cancels a fixed-term paid service mid-term, the Company refunds the amount paid less the fees attributable to the period already provided and a cancellation charge. Under the Content User Protection Guidelines that charge may not significantly exceed the loss caused by the cancellation, and the Company limits it to no more than 10 per cent of the refundable amount.

(4) Where the user is unable to use the Service normally due to the Company’s fault, the user may request a refund of the fees for the affected period or an extension of the subscription term.

(5) Refunds are made within 3 business days of the request, by the same means as the original payment where possible, and otherwise to an account nominated by the user.

(6) Termination and refunds under institutional agreements are governed by that agreement; where it is silent, this Article applies.

(1) Users must not:

• transfer, lend or share an account or login credentials;
• reproduce, transmit, publish or distribute books, audio, questions, images or other content on the Service, or create derivative works from it, without the prior consent of the Company or the rights holder;
• access the Service or collect data from it by automated means (crawlers, bots, scrapers and the like);
• reverse-engineer or decompile the Service, or circumvent access controls or other security measures;
• collect or use another person’s personal information without authorisation, or view another person’s learning records without permission;
• use the Read Aloud feature for purposes other than learning, or record another person’s voice without their consent; or
• interfere with the stable operation of the Service or with other users’ use of it.

(2) Teachers and institution administrators must use their permissions only for teaching and institutional administration, and must not use students’ learning records for any other purpose or disclose them to third parties.

(1) Copyright and other intellectual property rights in the Service and in content produced by the Company belong to the Company or the relevant rights holder.

(2) Third-party content in the Service, including English-language books, is provided under licence from the relevant rights holder. Users may use it only within the Service and for learning purposes, and may not extract it from the Service.

(3) Rights in teaching materials created by a teacher using the authoring tools belong to that teacher or their Institution. The Company may store, reproduce and display such materials only as necessary to provide the Service, back it up and provide technical support.

(1) The Company uses artificial-intelligence technology for automated pronunciation and fluency assessment, reading-level determination, learning-summary generation and question generation. The external AI services used are disclosed in the Privacy Policy.

(3) Recording conditions, microphone quality, background noise and individual speech characteristics may cause assessment results to differ from actual performance.

(4) Users may request an explanation of, or refuse, a decision made by automated means — such as the determination of a reading level and the resulting range of books shown — under Article 37-2 of the Personal Information Protection Act. The Privacy Policy sets out the procedure.

(5) Teachers and institution administrators can manually adjust a student’s reading level and book range; this operates as the means of human intervention in the automated decision.

(2) Where the Company wishes to use learning records to improve an AI model, it must first obtain the express consent of the Institution or the legal representative. Such consent is not enabled by default and may be withdrawn at any time.

(3) Declining or withdrawing that consent has no adverse effect whatsoever on the user’s use of the Service.

(4) The Company contractually requires the external providers used to deliver the AI features not to use data received from the Company to train their own models.

(1) The Company may change the Service. Material changes are notified at least 7 days in advance, or 30 days in advance where the change is unfavourable to users.

(2) The Company may temporarily suspend the Service for maintenance or inspection, in the event of force majeure such as power or communications failure, or where an external cloud or AI provider suffers an outage.

(3) Scheduled maintenance is notified in advance; in urgent cases notice may be given afterwards.

(4) If the Company discontinues the Service it will give at least 30 days’ notice and explain how and by when users may download their learning records.

(1) Users may terminate their agreement at any time through the Service or by contacting customer support.

(2) Where a user breaches Article 11, the Company may restrict use or terminate the agreement after giving notice. Where urgent action is needed to protect the stable operation of the Service, the Company may act first and notify promptly afterwards.

(3) On termination, personal information and learning records are destroyed, or returned to the Institution, in accordance with the periods and procedures set out in the Privacy Policy.

(1) The Company is not liable for loss caused by force majeure or events of equivalent character, or by the user’s own fault.

(2) The Company does not guarantee any particular learning outcome.

(3) Except in cases of the Company’s wilful misconduct or gross negligence, the Company’s liability in damages is limited to the total fees paid by the user to the Company in the three months immediately preceding the date the loss arose. This limitation may not apply to users who are consumers, to the extent provided by the Act on the Regulation of Terms and Conditions and other applicable law.

(4) The Company is not liable for loss arising from an Institution’s or teacher’s use of student learning records for purposes other than those permitted.

(1) These Terms are governed by and construed in accordance with the laws of the Republic of Korea.

(2) This English text is a translation provided for convenience. In the event of any inconsistency between the Korean and English editions, the Korean edition prevails.

(3) Disputes are to be resolved by mutual discussion in the first instance. Failing agreement, either party may bring proceedings before the court having jurisdiction under the Civil Procedure Act.

(4) Users who are consumers may apply for dispute mediation to the Korea Consumer Agency or a consumer dispute mediation body established by a metropolitan or provincial government, in accordance with the Act on Consumer Protection in Electronic Commerce.
