  2. This license takes effect when you install the Service and continues until it is terminated by you or us in accordance with these Terms, or until the Service is discontinued. Upon termination, you must immediately stop using the Service and delete it from your device.
  3. This license does not transfer any rights in the Service's software itself. All intellectual property rights relating to the Service belong to us or the applicable rights holders.

Article 6 (User Content)

  1. Copyright and other rights in User Content belong to you or the applicable rights holder. We claim no rights in User Content.

  13. Interfering with our operation of the Service, or any other act we reasonably deem inappropriate

Article 8 (Subscriptions)

  1. Some features of the Service are available by subscribing to the Pro plan or Max plan. Details of the features provided under each plan are displayed on the Service's in-app purchase screen.
  2. Subscription pricing, billing periods, features, renewal terms, and similar details are displayed on the Service's in-app purchase screen. In case of any discrepancy, the pricing displayed by the Store takes precedence.
  3. The monthly usage limits for the image search feature (Pro plan) and the Automatic Card Import Feature (Max plan only) are calculated and reset based on your Subscription's renewal date, not the calendar month. In addition, to prevent fraudulent use and automated access, all plans are subject to an hourly usage limit. The "unlimited" image search offered under the Max plan is provided subject to this anti-abuse limit and is not guaranteed to be unlimited. These specific limits may be changed at our discretion for the stable operation of the Service.
  4. Cloud sync covers only the text information of decks and flashcards (terms, meanings, example sentences, learning status, etc.). The image files attached to flashcards are always stored only on your device, regardless of Subscription status, and are not included in cloud sync or backups. See our Privacy Policy for details.
  5. Payment for Subscriptions is made through the Store. Payment methods, receipts, cancellation, and refunds are governed by the applicable Store's rules.
  6. Subscriptions renew automatically. Unless you turn off auto-renewal at least 24 hours before the end of the current billing period, the Subscription will automatically renew for the same period and you will be charged the applicable fee.
  7. To turn off auto-renewal:
    • iOS: Settings → [your name] (Apple ID) → Subscriptions
    • Android: Google Play → Payments & subscriptions → Subscriptions
  8. After cancellation, you may continue to use the features of your plan until the end of the current billing period. We do not provide prorated refunds for mid-period cancellations.
  9. The Service is digital content (a form of mail-order sale under Japan's Act on Specified Commercial Transactions) and is not subject to the statutory cooling-off period under that Act. In principle, we do not provide refunds, although refunds may be granted in accordance with the applicable Store's refund policy. Please contact the Store from which you purchased for refund inquiries.
  10. We may change Subscription pricing, features, or terms within a reasonable scope, in accordance with the procedure set out in Article 18.

Article 9 (Suspension of the Service)

    • When provision of the Service becomes difficult due to earthquake, lightning, fire, power outage, or other force majeure event
    • When a computer or communication line is stopped due to an accident
    • When a failure at a subcontractor or another event beyond our reasonable control occurs
    • When we otherwise determine that providing the Service has become difficult
  2. We bear no liability beyond the scope of Article 13 for damage caused to you by a suspension or interruption described above.

    • Violate the anti-organized-crime provision in Article 16
    • Otherwise engage in conduct that we reasonably determine to be inappropriate use of the Service

Article 11 (Changes to or Discontinuation of the Service)

We may change, add to, or remove features of the Service upon prior notice to you. We may also discontinue all or part of the Service upon reasonable prior notice if we determine it is necessary. In connection with any discontinuation, we will endeavor to notify you in advance and provide reasonable means, such as a data export option, for handling your User Content. We bear no liability beyond the scope of Article 13 for damage caused to you by a change to or discontinuation of the Service.

Article 12 (Disclaimer of Warranties)

  1. We make no warranty, express or implied, regarding the Service, including as to merchantability, fitness for a particular purpose, non-infringement of third-party rights, accuracy, completeness, reliability, timeliness, or continuity. The Service is provided "AS IS" and "AS AVAILABLE", and you use the Service at your own discretion and risk.
  2. Flashcards and other output generated by the Automatic Card Import Feature are the result of automated processing and may contain errors, omissions, or inaccurate information. We make no warranty as to the accuracy, completeness, or appropriateness of the output of the Automatic Card Import Feature. You are responsible for reviewing and, where necessary, correcting the output of the Automatic Card Import Feature before relying on it.

If your use of the Service or breach of these Terms causes damage (including attorneys' fees) to us or a third party, you shall compensate for such damage at your own expense and responsibility.

Article 15 (Provisions Relating to the Store)

  1. These Terms are an agreement between you and us, and not with Apple Inc., Google LLC, or any other Store operator. We, not Apple Inc., Google LLC, or any other Store operator, are responsible for the Service and its content.
  2. If you use the Service through the Store, the applicable Store's terms of service also apply in addition to these Terms. In the event of a conflict between these Terms and a Store's terms of service, the Store's terms of service shall prevail to the extent of the conflict.
  3. You acknowledge that Apple Inc., Google LLC, and other Store operators are third-party beneficiaries of these Terms and have the right to enforce these Terms against you.
  4. Your use of the Service is conditioned on your compliance with the applicable Store's terms of service.

Article 17 (Handling of Personal Information)

The handling of your personal information that we collect in connection with the Service is governed by our separately established Privacy Policy. The Privacy Policy forms an integral part of these Terms.

Article 18 (Changes to These Terms)

  1. On the premise that these Terms constitute standard terms under Article 548-2 of the Civil Code of Japan, we may change these Terms without individual user consent, in accordance with Article 548-4 of the Civil Code, where either of the following applies:
    • The change is in the general interest of users; or
    • The change does not conflict with the purpose of these Terms, and is reasonable in light of the necessity of the change, the appropriateness of the content after the change, the existence and content of any provision regarding changes to these Terms, and other circumstances relating to the change.
  2. When changing these Terms, we will determine the effective date of the revised Terms and notify users of the content of the change and its effective date, with reasonable advance notice, by posting within the Service or on our website.
  3. If you use the Service on or after the effective date of the revised Terms, you are deemed to have agreed to the revised Terms.

Article 19 (Communications and Notices)

Inquiries or other communications or notices from users to us regarding the Service, and notices of changes to these Terms or other communications from us to users, shall be made by the method we designate (display within the Service, posting on our website, sending to your registered email address, etc.).

Article 20 (Governing Law; Jurisdiction)

  1. These Terms shall be governed by and construed in accordance with the laws of Japan.
  2. Any dispute arising out of or in connection with the Service or these Terms shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance. However, if you qualify as a "consumer" under Japan's Consumer Contract Act, this provision does not preclude you from filing suit in the court having jurisdiction over your place of residence, or in any other court of competent jurisdiction permitted under the Consumer Contract Act or other applicable law.

Article 21 (Severability)

If any provision of these Terms, or any part thereof, is held invalid or unenforceable under applicable law, the remaining provisions of these Terms shall continue in full force and effect. We and you agree to amend the invalid or unenforceable provision to the extent necessary to give effect to its original intent, in a manner that is valid and enforceable.

Article 21-2 (Referral Program)

  1. To promote use of the Service, we may offer a program (the "Program") under which a user who refers another user obtains the right for both the referrer and the referee to purchase a paid Subscription at a discounted price (the "Referral Benefit").
  2. The content, conditions of eligibility, and terms of use of the Referral Benefit are displayed within the Service's in-app screens. We may change the content of the Referral Benefit, or suspend or terminate the Program itself, upon prior notice to users (except in urgent cases).
  3. You must not engage in any of the following. If you do, we may revoke a granted Referral Benefit or restrict your future participation in the Program:
    • Making referrals between multiple accounts you control
    • Making referrals from multiple accounts using the same Apple ID or Google account
    • Making referrals through fraudulent means (automated tools, attempts via multiple IP addresses, etc.)
    • Making referrals in exchange for monetary consideration (excluding voluntary word-of-mouth recommendations)
    • Any other conduct we reasonably determine to be contrary to the purpose of the Program
  4. Due to Store restrictions, the Referral Benefit is granted as the right to purchase a specific product ID (a discounted-price SKU). We use information obtained in connection with operating the Program (referral codes, hashed IP addresses, etc.) for the purpose of detecting and preventing fraudulent use. See our Privacy Policy for details.
  5. Once granted, the Referral Benefit (eligibility to purchase at the discounted price) remains valid indefinitely, except where revoked under the preceding paragraph. Cancelling a Subscription does not forfeit the Referral Benefit, and you may purchase the discounted-price SKU again when you re-subscribe. If you switch between the Pro plan and the Max plan, you may purchase the discounted-price SKU corresponding to the new plan. However, this does not apply if we change the content of the Program, or suspend or terminate the Program, under paragraph 2.
  6. If you post your referral code or invitation link on social media, a blog, or any other medium accessible to an indefinite number of people, please label the post clearly as promotional in connection with the Referral Benefit (e.g. "PR," "Ad," or "Referral Link"). This labeling is not required for a message sent individually to a specific acquaintance.
