Terms of Service

About this translation. This page is an English translation of maru's Japanese Terms of Service, provided for reference. The Japanese Terms of Service is the governing document; in the event of any discrepancy between the two, the Japanese version controls. The Japanese source is also still in draft form pending final legal review, so this translation may change without notice as that review concludes.

maru Terms of Service

Article 1. Scope

1. These Terms of Service set out the conditions for using maru (the "Service"), provided by Zanmaido K.K. (株式会社三昧堂; "we," "us," or "the Company").
2. Any user who uses the Service is deemed to have agreed to these Terms.

Article 2. Definitions

Article 3. Account Registration

1. Users shall register an account by the method we designate.
2. Registration requires a valid email address and other necessary information.
3. The Service is intended for users 18 years of age or older. Users under 18 may not register.
4. In principle, each User may hold only one account; obtaining multiple accounts is prohibited.
5. Users are responsible for managing their account information and password.

Article 4. Special Provisions for the Early-Access Period

1. The Service is currently offered on a pre-registration basis (this period, the "Early-Access Period"). During the Early-Access Period, functionality, performance, and stability may be limited.
2. During the Early-Access Period, we may change, suspend, or discontinue the Service without notice.
3. For data loss or service suspension during the Early-Access Period, we bear no liability beyond the scope of §8 (Disclaimers).
4. To help us improve the Service, Pre-Registered Users agree to our use of feedback, usage logs, and the content of reports the Service generates for them. We use this information to confirm report quality (pre-delivery review and post-delivery quality improvement). Details of this handling are set out in Privacy Policy §3.
5. Being in the Early-Access Period does not exempt Users from paid-plan fees. Paid-plan fees, the free trial, the start of billing, automatic renewal, and cancellation are governed by Article 5.

Article 5. Fees, Free Trial, Automatic Renewal, and Cancellation

5.1 Paid Plans and Fees

1. The fees for the Service's paid plans (the "Paid Plans") are as follows (all amounts include consumption tax).

1. The fees in this table are not indicative estimates; they are the contractual fees between the User and us. These fees are identical to those shown on our website's pricing page (https://nagaiki.ai/ja/plans) and in our Specified Commercial Transactions Act disclosure (https://nagaiki.ai/ja/commercial).
2. Users select one of the plans at the time of application. Fees accrue in units of the selected plan's renewal cycle.
3. If we revise our fees, we will announce the change in accordance with §11 (Amendment of Terms). The revised fee applies from the renewal following the announcement.

5.2 Free Trial Period

1. Applications for a Paid Plan come with a 5-day free trial period (the "Free Trial Period"). No fee is charged during the Free Trial Period.
2. The Free Trial Period is granted only once per account. If a User who has previously received a Free Trial Period applies again, no Free Trial Period is granted, and the first-period fee for the selected plan is charged at the time of application.
3. Registration of a payment method (such as a credit card) is required to apply, regardless of whether a Free Trial Period applies.
4. If no valid payment method is registered at the end of the Free Trial Period, we treat the application as cancelled and do not begin the Paid Plan.
5. No Free Trial Period is granted when applying using a promotional code under §5.5.

5.3 Start of Billing and Automatic Renewal

1. At the end of the Free Trial Period, the account automatically transitions to the Paid Plan, and the fee for the selected plan is charged. Where no Free Trial Period is granted (§5.2, paragraphs 2 and 5), the first-period fee is charged at the time of application, or at the end of the free period under §5.5.
2. Unless the User cancels in accordance with §5.4, the Paid Plan automatically renews at each renewal cycle of the selected plan, and the fee for the corresponding period is charged at each renewal (Automatic Renewal).
3. Billing is processed through our payment processor (Stripe, Inc.; United States) against the payment method the User has registered. We do not retain card information ourselves; only the payment processor retains it.
4. We send a notice to the registered email address before the Free Trial Period ends. Non-receipt of that notice does not affect the start of billing or the effect of Automatic Renewal.

5.4 Cancellation (Stopping Automatic Renewal)

1. Users may cancel a Paid Plan (stop Automatic Renewal) at any time from "Plan Management" in My Page (a customer portal provided by our payment processor).
2. If cancellation is completed by the day before the next renewal date, no further fee will be charged. If cancellation is completed after the next renewal date has passed, the fee for that renewal period has already accrued, and the cancellation takes effect at the end of that period.
3. After cancellation, Users may continue to use the Service until the end of the period already paid for.
4. If cancelled during the Free Trial Period, no fee is charged at all.
5. Refunds arising from cancellation are handled in accordance with our Specified Commercial Transactions Act disclosure and the refund policy posted on the same page (https://nagaiki.ai/ja/commercial).

5.5 Promotional Codes

1. If a User applies using a promotional code we issue, no fee is charged during the free period specified by that code.
2. After the free period ends, the fee for the selected plan is automatically charged in accordance with §5.3, and automatically renews thereafter.
3. Promotional codes are subject to an expiration date, a limit on the number of uses, eligible plans, and other conditions. The conditions for each code are as we separately specify for that code.

5.6 Late Payment

1. If we are unable to collect a fee through the registered payment method, we will retry collection through our payment processor and allow a certain grace period.
2. Users may continue to use the Service during the grace period; however, if payment cannot be confirmed after the grace period has passed, we may suspend provision of the Service or terminate the Paid Plan.

Article 6. Prohibited Conduct

In using the Service, Users shall not engage in any of the following:

17. Any other conduct we deem inappropriate

Article 7. Intellectual Property Rights

1. All intellectual property rights relating to the Service belong to us or to those who have licensed them to us.
2. Copyright in content such as meal photos that a User uploads to the Service belongs to that User. The User grants us a license to use that content, free of charge and without restriction as to region, period, or method of reproduction, to the extent necessary for us to provide, improve, and statistically analyze the Service.
3. Feedback, improvement suggestions, and requests (collectively, "Feedback") that a User provides to us within the Service may be used freely by us for the improvement of the Service, and we owe the User no compensation or acknowledgment of rights in connection with that use.

For details, see the separate "Medical Disclaimer" (medical_disclaimer_v1.md).

1. We do not warrant the accuracy, completeness, reliability, or fitness for any particular purpose of the Service's content, AI Output, or analysis results.
2. The CGM data and health data displayed are based on data provided by device manufacturers, and we are not responsible for the accuracy of that data.

1. Except where caused by our willful misconduct or gross negligence, we bear no liability for damages suffered by a User or a third party due to interruption, suspension, data loss, or failure of the Service.

A full list of our subprocessors is disclosed in Privacy Policy §5 and §6 and on the subprocessors page (https://nagaiki.ai/ja/subprocessors). The terms of use and any outages of these third-party services are governed by each provider's own terms, for which we bear no liability.
