This is a reference English translation. The authoritative version of these Terms is the Japanese text; if there is any discrepancy, the Japanese version prevails.
These Terms of Service (the “Terms”) set out the conditions of use of the voice interpretation service “Cotoa Interpreter” (the “Service”) provided by CoreVista-Japan, Inc. (the “Company”). Users use the Service only after agreeing to these Terms, the Privacy Policy, the Notation based on the Act on Specified Commercial Transactions, and any notices shown within the Service.
The Service performs speech recognition, translation, caption display, and speech synthesis based on the user’s language settings, using AI. Because the Service involves automated AI processing, the Company does not guarantee the completeness, accuracy, immediacy, or fitness for a particular purpose of the translation results, recognition results, captions, or audio output.
The user understands that translation results may contain errors, delays, omissions, recognition mistakes, inability to capture audio, and issues arising from the communication or device environment. In medical, welfare, nursing, legal, administrative, contractual, emergency, or other situations with serious impact on life, body, or property, do not rely solely on translation results; obtain confirmation by a professional, qualified person, or human as necessary.
The Service is used via account keys, seat keys, URLs, or QR codes issued to purchasers or administrators. The user is responsible for managing such keys and must not share, transfer, lend, publish, or leak them. Operations performed using such keys may be deemed to be performed by the manager or user, except where the Company is willfully or grossly negligent.
The user agrees that audio, text, and target information are processed for translation, speech recognition, speech synthesis, billing, balance management, and abuse prevention. When processing the audio of a counterpart, co-present person, or other third party, the user shall explain the use of the Service to that person and obtain the necessary consent. The user understands that audio may contain special-care-required personal information such as health, medical, disability, welfare, or living-circumstance information, and shall use the Service only with the consent of the relevant person.
The Service is available with a monthly free allowance and paid time top-ups. Fees, purchasable time, payment methods, delivery timing, and cancellation/refund conditions are set out in the purchase screen and the Notation based on the Act on Specified Commercial Transactions. Purchased time is granted to the account by the method the Company defines; reflection may take time due to communication failures, payment-processor delays, or system issues.
The user must not: (1) violate laws or public order; (2) infringe the rights, privacy, reputation, or credit of third parties; (3) process a third party’s audio without consent; (4) wrongfully obtain, share, sell, transfer, or publish account/seat keys, URLs, or QR codes; (5) circumvent or interfere with billing, balance management, usage limits, or security; (6) place excessive load on the Service, servers, API, or network; (7) perform reverse engineering, scraping, unauthorized access, bot use, vulnerability probing, or similar acts; (8) cause damage to the Company or third parties; or (9) other acts the Company deems inappropriate.
The Company may change, suspend, halt, or terminate all or part of the Service when necessary for maintenance, incident response, security, legal compliance, changes to external services, or other reasons. Except in unavoidable emergencies, the Company will endeavor to give prior notice of changes, suspensions, halts, or terminations that materially affect users, via display within the Service or other reasonable means.
The Company does not warrant that the Service always operates normally, that translations are always accurate, that it is usable on all devices/browsers/networks, or that it fits the user’s particular purpose. Where the Company is liable for damage to the user due to default, tort, or causes attributable to the Company, except in cases of the Company’s willful misconduct or gross negligence, the Company’s liability is limited to ordinary and direct damages actually incurred. Only where the Company is slightly negligent, the total liability is capped at the total Service fees the user paid to the Company in the six months before the date the damage occurred; for users with no payment in that period, the cap is JPY 1,500. This cap does not apply in cases of the Company’s willful misconduct or gross negligence.
The Company may change these Terms when (1) the change conforms to the general interest of users, or (2) the change does not contradict the purpose of the Terms and is reasonable in light of the necessity, the appropriateness of the revised content, and other circumstances. The Company will notify the revised content and effective date via display within the Service or other reasonable means; for material changes, notice is given before the effective date.
Minors must use the Service with the consent of a parent or legal representative.
The user represents and warrants that the user is not an antisocial force and will not allow antisocial forces to use the Service.
These Terms are governed by Japanese law. Any dispute between the Company and the user shall be subject to the Osaka District Court as the court of first instance by agreement; provided that, where the user is a consumer under the Consumer Contract Act, jurisdiction permitted by law is not precluded.
