1.
harming public order, good morals, or other social order;
2.
being objectively deemed to be for a criminal purpose or related to a criminal act;

To foster a healthy communication culture and operate the Service efficiently, the Company may delete, move, or refuse registration of data posted or provided by users where such data is deemed to fall under Article 12.

Article 15 (Responsibility for Use of the Service)
Except as specifically permitted in an explicit document signed by an authorized employee of the Company, users may not engage in business activities to sell unlawful products using the Service — in particular hacking, profit-seeking advertising, commercial activity through obscene sites, or the provision of unlawful commercial software. The Company is not responsible for the results of, or losses from, such business activities conducted in violation of this Article, or for legal measures taken by relevant authorities.
Article 16 (Payments and Subscriptions — In-App Purchases)
1.
The Service may offer Paid Services. Paid Services are purchased and billed exclusively through the in-app purchase systems of the Apple App Store and Google Play (the "Stores"). The Company does not provide a separate web-based or direct payment method.
2.
Payment, billing, and the means of payment are processed by the applicable Store under its own terms and policies. The Company does not collect or store users' card or financial account information, and may receive only limited transaction information such as an order or receipt identifier and subscription status.
3.
The specific contents, price, and conditions of each Paid Service are those displayed in the app or the Store at the time of purchase. A purchase is made subject to those details, these Terms, and the applicable Store's terms.
4.
(Subscriptions and auto-renewal) Where a Paid Service is provided as a subscription, the subscription period, billing cycle, and price are as displayed at the time of purchase. Unless you cancel before the end of the current period in the manner required by the applicable Store (generally at least 24 hours before the period ends), the subscription renews automatically for the same period at the then-current price, and the Store charges your payment method. You may manage or turn off auto-renewal at any time in your Store account settings; cancellation takes effect at the end of the current paid period, and amounts already paid are non-refundable except as required by the applicable Store's policy or by applicable law.
5.
(Refunds and Withdrawal) Refunds and withdrawal of purchases are handled in accordance with the applicable Store's policy and applicable laws, including the Act on the Consumer Protection in Electronic Commerce. Because payments are processed by the Stores, related requests may need to be made through the relevant Store.
6.
(Changes to Paid Services) The Company may change the price or other material conditions of a Paid Service. For subscriptions, the Company will give advance notice through the app, the Store, or other reasonable means before the change takes effect, and the change applies from the next renewal after the notice. If you do not agree to the change, you may cancel before it takes effect; continued use or renewal after the effective date constitutes acceptance.
7.
The Company may add, modify, or discontinue Paid Services for operational or legal reasons, and will provide reasonable prior notice where this materially affects users.
Account and billing help — September 9, 2026
This explanatory note accompanies Article 16. It does not replace the purchase terms, change the effective date of these Terms, or restrict existing statutory rights. Any amendment to contractual rights or obligations remains subject to Article 2.
•
Data reset: Starting fresh retains your account, existing subscription, remaining subscription period and auto-renewal setting. It does not restart a free trial or issue a refund.
•
Account deletion: Deleting a LuniFIT account ends access through that account but does not automatically cancel the Store subscription or request a refund. Manage auto-renewal in the Store where you purchased it to avoid further charges. You may request immediate account deletion even if a subscription period remains; cancellation or expiry is not a prerequisite.
•
Remaining subscription period: If you prefer to use the remaining paid period, cancel auto-renewal and keep your account until you are ready to delete it. This is not an automatic scheduled-deletion service.
•
Refunds: Reset, deletion, non-use and cancellation do not automatically trigger a refund or a calculation based on days used or remaining days. Refund eligibility and amounts follow applicable law, Store policies and your purchase terms. Mandatory withdrawal and refund rights remain available.
•
Purchase assistance: Submit Apple refund requests through Apple and consult Google Play refund guidance for Google purchases. Contact [info@keuhan.com](mailto:info@keuhan.com) for duplicate charges, missing access, service problems or restoration assistance, including after account deletion. Refund approval and receipt of funds are separate steps.
•
Restoration: A new account does not automatically restore deleted records, transfer an earlier subscription or grant a new trial. Contact support if purchase restoration fails before buying again.
See LuniFIT Support for subscription-management links and detailed help. Data deletion and legally required retention remain governed by the Privacy Policy.
