3. “Member” means a person who registers by providing personal information to the Company, and who continuously receives the Company’s information and may continue to use the Service.

5. “Paid service” means the subscription based services the Company provides for a fee (annual subscription, monthly subscription, and so on).
6. “Free trial” means the trial provided free of charge for a set period (7 days) before payment for a paid service.
7. “Content” means the text, voice transcripts, and similar material that a user enters or generates while using the Service (the “User Content”), and the responses, corrections, expression assets, and similar output the AI coach generates (the “Service Output”).

Article 3 (Posting and Amendment of the Terms)

1. The Company posts the content of these terms on the initial screen of the Service or on a linked screen so that users can easily find them.
2. The Company may amend these terms within the scope that does not violate applicable laws, including the Act on the Regulation of Terms and Conditions, the Act on the Consumer Protection in Electronic Commerce, and the Act on Promotion of Information and Communications Network Utilization and Information Protection.
3. When the Company amends the terms, it announces the amended terms together with the current terms, stating the effective date and the reason, from 7 days before the effective date. However, for a change unfavorable to users (a fee increase, a new usage restriction, a reduction in the scope of liability, and so on), the Company announces it from 30 days before the effective date and also provides individual notice, such as by app notification or email.
4. If, when announcing or notifying the amended terms under paragraph 3, the Company clearly stated that “a user who does not express refusal within the announcement or notice period is deemed to have agreed” and the user does not expressly refuse, the user is deemed to have agreed to the amended terms. A user who does not agree to the amended terms may express refusal and terminate the use agreement before the effective date, and in that case suffers no disadvantage.
5. Matters not provided for in these terms follow applicable laws and the terms of use and operating policies the Company sets for each individual service. Where the meaning of a term is unclear, it is interpreted in favor of the user.

The Company informs users of this fact at sign-up (onboarding), through a persistent indication on the conversation screen, and by reminding them again after a certain period.
2. The AI coach’s answers, corrections, translations, and expression suggestions may contain errors, inaccuracies, or bias. A user must not use the AI coach’s output as it is as a basis for important decisions in areas such as exams, work, medicine, law, or finance, and should obtain confirmation from an expert where necessary.
3. The Company does not guarantee any particular learning outcome (a higher score, passing an exam, improved ability, and so on). Learning results vary depending on the user’s amount and method of study.
4. The AI coach does not provide medical or mental health counseling. If a user is in a crisis or emergency, please seek help through the guidance within the Service (a crisis or mental health helpline in the user’s country or region, and, in an emergency, the local emergency services) or from a nearby specialized institution.
5. This article is a notice of facts about the inherent nature of AI, and is not a provision that waives the Company’s liability for its intent or gross negligence. The Company’s liability is governed by Articles 15 and 18.

Article 6 (Formation of the Use Agreement)

Users must provide accurate information for this purpose and must not falsely report their date of birth or similar information.
4. If a user is confirmed to be under 18 or refuses identity verification, the Company may restrict that user’s sign-up or use. Contracts and payments with minors (under 19) are governed by Article 11(6) and Article 5 of the Civil Act.

Differences in settlement and refund procedures by payment method follow the Refund and Cancellation Policy.
3. Prices, composition, and benefits may change according to the Company’s policy, and the terms of a subscription already paid for do not change during that subscription period. A change unfavorable to users, such as a price increase, is announced in advance under Article 3(3) and applies from the next renewal.

Article 10 (Automatic Conversion of the Free Trial and Advance Notice)

1. The free trial starts after a payment method is registered, and on expiry of the trial period (7 days) it automatically converts to, and is charged as, an annual subscription (KRW 99,000) without any additional consent. At the time of sign-up (start of the free trial), the Company clearly informs the user of the conditions of this automatic conversion (the conversion time, the payment amount, and how to cancel) and obtains the user’s consent.
2. The Company gives advance notice before an automatic conversion or auto-renewal payment as follows.
   • 2 days before (D-2) and 1 day before (D-1) the payment: notice of the scheduled conversion or renewal date, the payment amount, and how to cancel, by app notification and similar means
   • A user who does not want automatic conversion or renewal may cancel at any time from the time of notice until before the cancellation takes effect.
3. A user can cancel a subscription within two actions (two taps), and the cancellation path is provided at a level equivalent to the sign-up path. The Company does not make cancellation unreasonably difficult or require additional procedures.
4. If an auto-renewal payment fails, the Company retries for a certain grace period, and does not abruptly block features even during the grace period. If all retries fail, the paid service ends and the account converts to the free tier.

Article 11 (Withdrawal of Subscription, Cancellation, and Refund)

1. A user may cancel a subscription (stop the next payment) at any time. On cancellation, as a rule a subscription already paid for may be used until the end of that payment period, and a refund for mid-term cancellation follows paragraph 2 and the Refund and Withdrawal Policy.
2. The specific standards for withdrawal of subscription and refunds (the free trial, the withdrawal and mid-term cancellation refund formula for the annual subscription, the monthly subscription, refunds by payment method, and so on) are set out in the separate Refund and Cancellation Policy, and that policy forms part of these terms.
3. Under Article 27 of the Content Industry Promotion Act and Article 17(2) of the Electronic Commerce Act, withdrawal of subscription may be restricted where the provision of digital content has begun. However, the Company indicates in advance that withdrawal is restricted for such content, and takes measures required by law, such as providing a partial use (trial) opportunity.
4. If a user cannot use the Service normally due to a cause attributable to the Company (a serious service failure, and so on), the user may receive a corresponding refund.
5. On withdrawal of subscription, refund of payment is handled under Article 18 of the Electronic Commerce Act, and where a refund is delayed, related rules such as late payment interest apply.

Article 13 (Intellectual Property and Use of Content)

1. The rights to User Content (utterances, voice transcripts, and similar material the user enters) belong to the user. The user grants the Company the right to use (store, reproduce, process) that content to the extent necessary to provide, operate, and improve the Service (generating AI responses, correction, quality evaluation, and so on). The scope of this license is limited to the purpose of providing the Service, and use for model improvement follows the user’s separate consent and opt-out settings.
2. For the Service Output the AI coach generates (responses, corrections, expression assets, and so on), the Company allows the user to freely use it within the scope of the purpose of using the Service. However, the intellectual property belonging to the Company or a rightful holder, such as the software, design, trademarks, and AI model that make up the Service, belongs to the Company or that holder.
3. Due to the nature of AI generated output, identical or similar output may be provided to other users, and exclusive rights to the output may not be guaranteed. The Company indicates that content is AI generated under Article 31 of the Framework Act on Artificial Intelligence.
