Article 13 (Paid Services and Payment)
① The Company provides certain features of the Service (the Mayu weekly report, Mayu coach, visit-ready record summary, extended record storage, and similar) as the paid subscription service “Mayu Care” (the “Paid Service”). The specific contents, subscription period, and fees of the Paid Service are displayed on the purchase screen in the Service. ② A Paid Service agreement is formed when the member reviews the payment conditions on the purchase screen, separately agrees to them, and completes payment. Payment is processed through the in-app payment system of an app market operator such as the Apple App Store, and the Company does not directly collect or store payment-method information such as credit card numbers. ③ (Free trial) The Company may offer a free trial period to members subscribing to the Paid Service for the first time; whether a trial is offered, and its length, are displayed on the purchase screen. If the member does not cancel before the free trial ends, the subscription the member agreed to is charged automatically from the day the trial ends, and the Company notifies the member of the conversion date, amount, and payment method, and obtains the member’s consent, no later than 30 days before the paid conversion. If the member cancels during the trial, no fee is charged and the member may continue to use the Paid Service until the trial period ends. ④ (Auto-renewal) The Paid Service renews and is charged automatically for each subscription period unless the member cancels. If the Company raises the subscription fee, it notifies members of the change date and the prices before and after the change, and obtains the consent of recurring-payment members, no later than 30 days before the change takes effect.
Article 13-2 (Cancellation, Withdrawal of Offer, and Refunds)
① (Cancellation) Members may request cancellation of the Paid Service at any time through the subscription management feature of the app market. After cancellation, the member may continue to use the Paid Service until the end of the period already paid for, after which the account switches to the free plan. ② (Records after switching) Even after switching to the free plan, the member’s records are not deleted and continue to be stored and displayed within the scope the free plan provides. Re-subscribing to the Paid Service restores access to paid features. ③ (Withdrawal of offer) A member may withdraw their offer and receive a full refund within 7 days of payment if they have not used the Paid Service. Other matters concerning withdrawal and its limits follow applicable laws, including the Act on the Consumer Protection in Electronic Commerce of Korea. ④ (Refund procedure) Refunds for in-app payments made through an app market operator may also be subject to that operator’s refund policy, provided that if the app market’s refund policy is less favorable to the member than the Act on the Consumer Protection in Electronic Commerce, that Act prevails. Customer support (support@habitushealth.app) guides members through the refund procedure. ⑤ (Discontinuation) If the Company discontinues the Paid Service for its own reasons, it gives notice 30 days in advance and refunds, on a pro-rata basis, the fee for the remaining period already paid for but not provided. ⑥ (Erroneous charges) If a fee is charged incorrectly due to a cause attributable to the Company, the Company refunds the full amount.

Article 16 (Privacy)

Matters concerning the processing of personal information are governed by the Privacy Policy and individual consent forms, not by these Terms.
Article 17 (Disclaimer)
① The Company is exempt from liability where it cannot provide the Service due to force majeure such as natural disaster, war, or suspension of service by a key telecommunications operator. ② The Company has no obligation to intervene in service disruptions caused by reasons attributable to the member, or in disputes arising between members or between a member and a third party through the Service, and is not liable for resulting damages. ③ The Service does not guarantee health outcomes such as weight loss, and final responsibility for health decisions made with reference to its records and guidance rests with the member and the member’s medical team. ④ The exemptions in Paragraphs 1 through 3 do not apply to damages caused by the Company’s intent or gross negligence (Article 7 of the Act on the Regulation of Terms and Conditions of Korea).
Article 18 (Damages)
① If the Company or a member causes damage to the other party by violating these Terms, the party at fault must compensate for the damage in accordance with applicable laws. ② Even where the Company is liable, unless the Company acted with intent or gross negligence, the scope of compensation is limited to ordinary damages, and damages arising from special circumstances are compensated only where the Company knew or could have known of those circumstances.
Article 19 (Governing Law and Jurisdiction)
① These Terms and the use of the Service are governed by the laws of the Republic of Korea. ② If a dispute arises between the Company and a member in connection with the Service, the parties will first consult in good faith; if consultation fails, either party may file suit with the competent court under the Civil Procedure Act of Korea. ③ Members may apply for dispute mediation with the Consumer Dispute Mediation Committee of the Korea Consumer Agency under the Framework Act on Consumers.
