Terms of Service — English

Effective 6 October 2026 · MOSIM-TERMS-2026-10-06-R2

1. Purpose and operator

These terms govern MOSIM's app and web services and the rights and duties of users and 주식회사 와리가리 (the “Company”). Representative: Hyogyu Kim. Business registration: 317-86-00974. Address: 3rd floor, unit 3-73, 80 Nonhyeon-ro, Gangnam-gu, Seoul, Republic of Korea (Gaepo-dong, Jiseong Building). Contact: reeta.kim@mosim.ai.

2. Services

MOSIM provides membership management, hospital/partner information, consultation and translation, booking requests and coordination, concierge services and AI CHECK reference guidance. Access depends on role, affiliation, approval and the individual service conditions.

The Company is not a medical institution and does not diagnose, prescribe or treat through the app. Medical decisions and care are the responsibility of the relevant medical institution and professionals. AI CHECK and translation do not replace professional care or verification by a qualified interpreter. In an emergency, contact local emergency medical services without waiting for an app response.

3. Registration and account security

Provide accurate information you are authorized to use. Accounts requiring approval gain relevant access after review. Identity misuse, account transfer/lending, credential sharing and unauthorized access are prohibited. Update changed information and report suspected misuse. Laws requiring guardian consent, including for minors' paid contracts, apply. If booking or applying for someone else, obtain the necessary authority and consent.

4. Membership tiers and benefits

Tiers, benefits, quotas and conditions appear on the relevant screens and individual notices. Applying or paying alone does not confirm an upgrade or benefit use; approval, usage, cancellations and refunds may affect eligibility. We announce changes and timing without unfairly impairing existing contracts or statutory rights.

5. Consultations, bookings and concierge

Submitting a booking request is not confirmation. Check the confirmation from the hospital, partner or coordinator. Vehicles, drivers/interpreters, flights, hotel rooms and itineraries depend on dates and availability. Alternatives and additional charges require notice and your confirmation.

The provider, inclusions/exclusions, dates, times, party size, total price, taxes, additional fees and cancellation conditions are explained before payment or final confirmation. Unconfirmed products or arrangements are not guaranteed. Responsibilities for the Company's own services and third-party hospital/partner services depend on the relevant contracting parties.

6. Payment, cancellation and refunds

Where payment is available, use the methods and currency displayed at checkout. Exchange rates and international charges depend on the payment method and financial institution; no particular rate or automatic conversion is guaranteed. For services without in-app payment, an enquiry or booking request alone does not confirm payment or purchase. When payment is offered, available methods, total cost and cancellation/refund conditions are disclosed before payment.

Cancellation, refunds and withdrawal follow applicable law and conditions disclosed before the contract. Statutory rights are not excluded. Charges for services already supplied or actual cancellation costs require an explanation of the basis and calculation. Failure attributable to the Company is handled under the contract and law. Account deletion does not automatically cancel reservations or complete refunds.

7. Content, conversations and AI

Check that submitted information is lawful and accurate. Do not upload personal information, confidential material or protected works without authority, or use the service for illegality, fraud, threats or attacks. Content and records are processed as necessary for service provision; personal data is governed by the Privacy Policy and applicable individual consent.

AI and translation may contain errors or omissions. Confirm important medical information, prices, times and booking conditions against the original and with the responsible person. Content or access may be restricted as necessary when infringement is established.

8. Changes, interruptions and restrictions

Maintenance, outages, security threats and legal compliance may require changes or temporary interruption. Foreseeable events are notified in advance; urgent events are explained afterwards where possible. Restrictions for violations include reasons and an appeal method, except that urgent harm prevention may require action first.

9. Account deletion and privacy

Request withdrawal/deletion through the in-app account-deletion function or the public deletion instructions. Identity and linked records are reviewed and the result communicated. Pending contracts/disputes and records subject to legal retention are handled separately within the necessary scope. Uninstalling the app is not account deletion.

10. Liability and disputes

The Company and users are responsible for attributable damage under applicable law. These terms do not waive the Company's liability for intentional misconduct, gross negligence or statutory obligations. Responsibility for third-party medical and partner services follows the actual contracts and applicable law.

Contact our support email or customer service with complaints and disputes. We examine the facts and seek resolution. Korean law applies without excluding mandatory consumer protections or legally required jurisdiction applicable to you. Court jurisdiction follows applicable law.

11. Amendments and individual conditions

Changes, reasons and effective dates are announced in the app or website, with the legally required consent process where applicable. Individual service conditions are disclosed before contract formation and apply only insofar as consistent with these terms and mandatory law. Mandatory legal rights are not limited by this English version.
