If you are a minor (under 18 years of age), please obtain the consent of a parent or other legal representative before using the Service (including subscribing to a paid plan or purchasing Coins).

If a user engages in an act described above or otherwise violates these Terms, we may suspend all or part of the user’s access without prior notice to an extent appropriate to the nature and severity of the violation. We may delete the account if there is a serious violation, such as a violation of laws, regulations, or public order and morals or interference with operation of the Service, or if violations are repeated after a warning from us. We will notify the user of the action and reason by email to the registered address. 3. If an account is deleted under the preceding paragraph, fees already paid will not be refunded and remaining Coins will expire, except where a refund is required by law.

Article 4 (Service Suspension)

We may temporarily suspend or interrupt all or part of the Service without prior notice in the following cases: • Emergency system maintenance is required • Action is required to address improper use or unauthorized access • A communications network or external service necessary to provide the Service experiences a failure • Required by law • An earthquake, lightning, fire, or other force majeure makes provision of the Service difficult 2. If the Service is suspended or interrupted under the preceding paragraph, we will endeavor to provide notice promptly afterward on our website. 3. In addition to the preceding paragraphs, we may temporarily suspend all or part of the Service for system maintenance after providing advance notice on our website. Notice may be omitted for work completed in a short period.

Article 4-2 (Changes to and Discontinuation of the Service)

1. We may change the content of the Service or discontinue all or part of the Service. 2. We will give notice of the content and timing at least 30 days before any of the following actions by posting it on our website and, for users with an active paid plan or a balance of purchased Coins, also by email to their registered address: • Changing the price or content of a paid plan to the user’s disadvantage. A price change applies from the first renewal after 30 days have passed following notice • Discontinuing the entire Service • Discontinuing a principal feature of a paid plan • Discontinuing all features in which Coins can be used However, where urgently required by law, to address improper use, or to ensure safety, we may make the change or discontinuation without waiting 30 days. We will provide notice as promptly as reasonably possible. 3. If the entire Service or a paid plan is discontinued, the paid-plan agreement will end on the discontinuation date and no fees will be charged for any later period. If payment has already been made, we will issue a prorated refund for that period. 4. If the entire Service or all features in which Coins can be used are discontinued, we will not sell Coins on or after the date the discontinuation is announced. For unused purchased Coins remaining on the discontinuation date, we will refund, for each purchase, the amount paid multiplied by the proportion of unused Coins to the number purchased. Coins granted by us, including plan benefits, daily bonuses, and other distributions, expire upon discontinuation and are not refundable. The refund method and claim period, which will be at least 60 days, will be stated in the discontinuation notice. 5. This Article does not apply to temporary suspensions or interruptions under Article 4.

Article 5 (Intellectual Property)

1. Copyrights, patents, and other intellectual property rights relating to the Service belong to us or their rightful owners. Permission to use the Service under these Terms does not transfer those rights. 2. Rights in content entered by a user into an AI feature remain with the user or rightful owner. We may process entered content, including transmitting it to an external AI provider, to the extent necessary to provide the Service. 3. Users may use AI-generated content at their own responsibility. Identical or similar content may be generated for other users. AI-generated content is not a substitute for professional advice. We do not guarantee that AI-generated content does not infringe a third party’s rights.

Article 6 (Subscriptions)

1. A subscription (paid plan) has a one-month term and renews automatically for successive one-month periods unless the user completes cancellation. Prices are displayed in U.S. dollars on the pricing page, and the monthly price applicable at each renewal is charged at that renewal. Price changes are governed by Article 4-2, paragraph 2. 2. The initial fee is charged when the application is confirmed, at which time the paid-plan agreement is formed. Beginning with the second charge, the agreement renews and the registered payment method is charged each month on the same day and at the same time as the initial payment. If that day does not exist in a month, renewal occurs on the final day of that month. The next renewal and charge date and time are displayed under “Next billing date” on the dashboard. 3. Cancellation is completed by opening the payment provider’s (Stripe) page from “Manage or cancel plan” on the dashboard and completing the procedure there. If cancellation is completed before the next billing date and time displayed on the dashboard, no subsequent fee will be charged. If the user cannot log in or cannot complete the procedure on that page, the user may notify us by email, stating the service used to log in and either the registered email address or the payment date, time, and amount. In that case, cancellation is treated as completed when the email reaches us. 4. After cancellation, the Service remains available until the end of the paid period. 5. If the user cancels for the user’s own reasons, we do not provide a prorated refund for the paid period. However, we will issue a refund where the Service could not be provided for reasons attributable to us, proportionate to the unavailable period, where a duplicate or excessive charge occurred, or where otherwise required by law. Refunds are made to the payment method used. This provision does not limit users’ rights under applicable law. 6. If renewal payment cannot be completed because of a problem with the user’s payment method or a similar reason, paid-plan features are unavailable until payment is completed. The payment provider may retry the charge. If payment is completed, the usage period remains the one-month period beginning on the original billing date. If payment is not completed, we may terminate the paid-plan agreement and will make no charges after termination. 7. When an account is deleted, including under Article 3, paragraph 2, the paid-plan agreement ends at the same time and no subsequent charges will be made. If the user deletes the account, including deletion by us at the user’s request, paragraph 5 applies to fees for the paid period and no prorated refund is provided. 8. Coins included as a Pro plan benefit are granted when payment of each plan fee is completed.

Article 7 (Coins)

1. Coins (Labcoins) can only be used within the Service. 2. All coins, whether purchased or granted, expire one year from the date of acquisition. Expired coins are forfeited and cannot be restored. 3. “Date of acquisition” means the payment completion date for purchased coins, and the grant date for coins granted by us (daily bonuses, plan benefits, bug report rewards, and other distributions). 4. When coins are spent, coins granted as daily bonuses are used first, followed by the remaining coins in order of the earliest expiration date. 5. Coins cannot be refunded or exchanged for cash. 6. Cancelling a paid plan does not cause remaining Coins to expire before their respective expiration dates. However, among features in which Coins can be used, those that require a paid-plan agreement cannot be used after cancellation. 7. If a user deletes the account, including deletion by us at the user’s request, all Coins remaining in that account expire upon deletion and cannot be restored or refunded. Coins in an account deleted by us under Article 3, paragraph 2 are handled under Article 3, paragraph 3. 8. Notwithstanding paragraph 5, a refund or reimbursement will be provided in the following cases: • Purchased Coins could not be provided for reasons attributable to us • A duplicate or excessive charge occurred • Article 4-2, paragraph 4 applies • A refund is otherwise required by law

Article 8 (labmoney)

1. labmoney is a number used for play in games on the Service. We grant it free of charge. It cannot be purchased. 2. labmoney has no monetary value. It cannot be exchanged for cash, Coins (Labcoins), paid plans, goods, services, discounts, or any other economic benefit. 3. labmoney cannot be transferred or lent to, or bought from or sold to, other users. Accounts holding labmoney cannot be transferred or sold either. 4. A labmoney balance goes up and down based on information sent from the user’s device as games are played. We do not guarantee its accuracy or continuity. We may correct or erase labmoney balances, change how labmoney works, or discontinue it when needed to address malfunctions or improper use, to change or end the Service, or for other operational reasons. When we discontinue labmoney, we will announce it on our website in advance. 5. labmoney is separate from the Coins described in Article 7. This Article does not apply to Coins or paid plans.

Article 9 (Disclaimer)

1. We do not guarantee that the Service is free from factual or legal defects or that content generated by AI is accurate. Our liability for damage caused to a user by a defect in the Service is governed by paragraphs 2 and 3. 2. If a user suffers damage due to our intentional misconduct or gross negligence, we are liable for that damage. This liability is not limited. 3. Except in the preceding paragraph, if a user suffers damage due to our breach of contract or tort, our liability is limited to ordinary and direct damage actually incurred by the user and to the amount of fees, including paid-plan fees and Coin purchase prices, paid by that user during the 12 months preceding the date the damage occurred. If that amount is less than 1,000 Japanese yen, the limit is 1,000 Japanese yen. Fees paid in U.S. dollars are converted to Japanese yen at the exchange rate on the payment date. This limit does not apply to refunds of fees provided for in these Terms. The limitations in this paragraph, including the monetary limit and restriction to ordinary and direct damage, do not apply to loss of life or bodily injury.

Article 10 (Changes to Terms)

1. We may change these Terms only in either of the following cases: • The change conforms to users’ general interests • The change does not conflict with the purpose of the agreement and is reasonable in light of the need for the change, the appropriateness of the changed terms, and other circumstances 2. Before changing these Terms, we will post on our website that the Terms will change, the content of the changed Terms, and their effective date. The changed Terms take effect on the posted effective date. 3. If a change disadvantages users, we will post the notice described in the preceding paragraph at least 30 days before the effective date and will also notify users with an active paid plan by email to their registered address. 4. A user who does not agree to a change may cancel the paid plan or delete the account before the effective date. Fees and Coins in that case are handled under Articles 6 and 7.

Article 11 (Governing Law and Jurisdiction)

1. These Terms are governed by Japanese law. 山口地方裁判所下関支部 or 下関簡易裁判所 shall have exclusive jurisdiction as the court of first instance over disputes concerning the Service. 2. The Japanese version of these Terms is the governing text. Translations into other languages are provided for reference only.
