Terms of Service

Effective date: October 15, 2026

This is a translation of the Korean original. If there is any discrepancy, the Korean version prevails.

Article 1 (Purpose)

These Terms set out the rights, obligations, and responsibilities between Recarve (the "Service") and its users in connection with use of the Service.

Article 2 (Definitions)

  1. "Service" means the mobile application that lets users register study materials, receive forgetting-curve-based spaced review notifications, and generate summaries, review questions, and supplementary explanations with AI.
  2. "User" means a person who agrees to these Terms and uses the Service.
  3. "Account" means the authentication credential issued through social sign-in (Google, Apple, Kakao, Naver) to identify a user.

Article 3 (Effect and Amendment of the Terms)

  1. These Terms take effect when posted on the Service screens or otherwise notified to users.
  2. The Service may amend these Terms to the extent permitted by applicable law, and will announce the effective date and reason for any amendment.

Article 4 (Account)

  1. Users create an account through social sign-in when using features that require authentication, such as creating cards.
  2. Users must not allow third parties to use their account.
  3. Users may terminate this agreement at any time through the in-app "Delete Account" feature.

Article 5 (Provision and Changes of the Service)

  1. The Service is, in principle, provided 24 hours a day, every day of the year.
  2. The Service may suspend all or part of the Service when necessary, such as for system maintenance, equipment failure, or circumstances of partner providers.
  3. AI analysis is provided within usage (quota) limits, and the limits and policies may change.

Article 5-2 (Paid Services)

  1. In addition to the free plan, the Service offers a paid subscription plan ("Pro"). The price, features (monthly AI analysis credits, ad removal, etc.), and billing cycle of Pro are as stated on the in-app subscription screen (Paywall).
  2. Pro payments are processed only through the app marketplace of the operating system the user uses (Apple App Store or Google Play). The Service does not directly collect or store payment card or other financial information.
  3. Unless cancelled, Pro renews automatically each billing cycle (monthly/yearly). A user who wishes to cancel before renewal can do so in the subscription management screen of the app marketplace where payment was made (App Store settings or Google Play subscriptions). The Service does not provide a way to cancel a subscription within the app.
  4. Withdrawal and refunds follow the refund policy and procedures of the app marketplace where payment was made (Apple App Store or Google Play). The Service may revoke Pro benefits according to the refund result processed by the marketplace.
  5. The one-time trial credits provided on the free plan do not carry over month to month. If a user subscribes to Pro while using trial credits, any remaining trial credits expire and are converted into Pro's monthly credits.
  6. Pro's monthly credits are valid only within the billing cycle in which they are granted and do not carry over to the next cycle.

Article 6 (User Obligations)

Users must not:

  1. Use another person's information or register false information
  2. Interfere with the operation of the Service or place excessive load on its servers
  3. Reverse engineer, copy, or distribute the Service, or use it abnormally through automated means
  4. Enter or transmit content that violates laws or public order and morals

Article 7 (Rights and Responsibility for Content)

  1. Copyright in the study materials a user enters into the Service belongs to the user or the rightful owner.
  2. Users warrant that they hold the necessary rights in the materials they enter, and are responsible for any disputes arising from them.
  3. AI-generated results are not guaranteed to be accurate, and users should use them only as reference material.

Article 8 (Disclaimer)

  1. The Service is not liable for service interruptions caused by force majeure, such as natural disasters or outages of partner providers (authentication, AI, and infrastructure providers).
  2. The Service is not liable for loss of study data that users store on their devices. Users can back up their own data with the "Export" feature.
  3. The Service does not warrant the accuracy, completeness, or usefulness of AI-generated results.

Article 9 (Governing Law and Jurisdiction)

These Terms are governed by and construed in accordance with the laws of the Republic of Korea, and disputes relating to use of the Service shall be brought before the court having jurisdiction under the Korean Civil Procedure Act. Nothing in this Article limits any mandatory consumer protection rights you may have under the laws of your country of residence.
