PleumRouter Terms of Service

Article 3 (Definitions)

(1) "Service" means the pay-as-you-go service provided by the Company that connects and brokers (routes) multiple artificial intelligence (AI) models through a single API and charges according to usage.

(2) "Credit" means a prepaid means of payment that a Member holds by paying in advance to settle Service usage fees. Credit balances and prices are shown on screen in credit units (1 credit = 1 local currency unit); actual transaction amounts (charging, payment, refund) are based on Korean won (KRW).

(3) "First-Payment Bonus" means Credit granted by the Company without charge when a Member completes a first payment (first purchase): a bonus of 10% of the topped-up Credit (capped at 5,000 credits). Duplicate receipt through the same physical card number, same payment instrument, or linked multiple accounts is restricted; if improper receipt is confirmed, the bonus granted will be recovered or deducted upon cancellation. The Company may adjust whether the bonus is granted, and at what rate or cap, as operationally necessary.

Article 4 (Specification, Delivery, and Amendment of the Terms)

(1) The Company posts these Terms and their revision history where Members can easily review them and provides an electronic copy on request.

(2) The Company may amend these Terms within the scope that does not violate applicable laws. When amending, the Company shall specify the effective date and the reason for the amendment and announce it within the Service from seven (7) days before the effective date (thirty (30) days before for changes that are disadvantageous or material to Members). Material changes concerning Credit, a prepaid means of payment, shall be posted at least one month before the change and notified to Members by email or otherwise.

(3) If a Member does not agree to the amended Terms, the Member may terminate the use contract.

Article 5 (Contents and Provision of the Service)

(1) The Company provides (1) integrated API routing to multiple AI models, (2) pay-as-you-go charging according to usage (tokens, etc.) and deduction of Credit, and (3) ancillary services such as Credit charging, transaction history lookup, and tax invoice issuance.

(2) Pursuant to Article 13(2), items 4 and 7 of the E-Commerce Act, Credit is credited to a Member's account and becomes available for use immediately upon completion of payment and charging, with no separate physical delivery process. The technical specifications and integration methods required to use the Service are provided through the developer documentation (API Reference) furnished by the Company.

(3) The Company may temporarily suspend provision of the Service in the event of maintenance, inspection, or failure of facilities, communication interruption, or substantial operational reasons, in which case it shall announce the reason and period in advance. Provision of certain models may be discontinued due to policy changes by upstream AI providers (OpenAI, Anthropic, Google, etc.).

(4) Members may use Bring Your Own Key (BYOK) functionality to register their own external AI provider API keys and connect directly to providers. BYOK is provided free of charge by default; however, for fair resource allocation, high-volume usage exceeding 10 billion tokens per week may incur a platform routing fee of 300 credits per 1 million (1M) tokens. If credit balance is insufficient or delinquent, BYOK request routing may be temporarily suspended.

Article 6 (Price, Charging, and Method of Payment)

(1) Pursuant to Articles 8 and 13 of the E-Commerce Act, the Company clearly indicates and notifies the Credit unit price, the pay-as-you-go unit price (rate) per AI model, the means of payment, and the time of payment on the pricing information page and on the screen immediately preceding payment.

(2) Service usage fees are calculated based on the actual usage (model, tokens, etc.) by the Member and deducted from the Credit held by the Member.

(3) On the screen immediately preceding payment, the Company notifies the details, amount, and validity period of the Credit to be charged and obtains the Member's confirmation, and upon completion of payment gives notice by email or otherwise. A Member may view payment and transaction records at any time on My Page.

Article 7 (Means of Payment and Fees by Means of Payment)

(1) A Member may charge Credit by credit or debit card (single payment). Account transfer, simple payment (KakaoPay, NaverPay, SamsungPay), auto-charge (recurring payment), mobile micropayment, gift certificate payment, virtual account (bank deposit), and installment payment are not currently offered.

(2) Reflecting the costs of operating the Credit charging service (payment processing, infrastructure, customer support, etc.), the Company may impose, commonly on all means of payment under paragraph (1), a platform fee equal to a certain percentage of the charged amount. The platform fee rate may change according to the Company's policy, and the current rate is clearly notified on the screen immediately preceding payment and on the pricing information page. Because this fee applies equally to all means of payment, it is not imposed discriminatorily on users of any particular means of payment.

(3) No additional fee per means of payment, other than the platform fee under paragraph (2), is imposed on any means of payment under paragraph (1).

(4) Pursuant to Article 19(1) and (4) of the Specialized Credit Finance Business Act, the Company does not pass on credit card merchant fees to card members and does not treat Members disadvantageously on the ground of credit card payment. The platform fee under paragraph (2) applies equally to all means of payment.

(5) Pursuant to Article 19(7) of the Specialized Credit Finance Business Act, where payment is routed through a payment gateway (PG), the Company makes the trade name and address of the Company as the actual seller known to Members, and responds to legitimate requests for transaction cancellation or refund.

(6) The Company may offer Workspace collaboration features and account subscriptions for individual, team, and B2B use. Workspace invitations and team member participation are currently provided free of charge without separate seat fees. If the Company introduces paid seat subscriptions or new specialized SKUs in the future, it will announce the pricing and terms in advance and obtain Members' explicit consent. Benefits associated with paid subscriptions apply only to the billing account and not to members' personal accounts.

(7) Paid subscriptions are prepaid monthly to the registered card. Seat increases or decreases are reflected at the next renewal, and cancellation triggers a final settlement based on actual participation time and amounts paid. Any shortfall may be charged to the saved payment method. Overpayments are tracked by original payment: amounts from a payment made within the preceding 7 days are refunded to that payment method; older overpayments are credited to the Member's PleumRouter account excluding VAT. Carried credits are used in first-in, first-out order. A statutory withdrawal within 7 days follows applicable law and Article 10; paid seat participation or receipt of a top-up fee waiver counts as use of the service.

(8) The Student Free Benefit covers only one seat for the student's own account. A newly eligible student receives 6 months, and an existing eligible student receives 6 additional months after any remaining valid period. A subscription coupon also covers only one seat for the recipient's own account; additional people are paid seats. An account may start without payment when the owner's free benefit makes the initial subscription amount zero. Before the first paid renewal, the Company requests a payment method and separate consent to automatic payment. Without that consent, the free subscription ends and does not convert to a paid subscription.

(9) B2B postpaid service is available only after the platform administrator registers the contract, the account owner agrees to its terms, and an administrator approves it. The account owner is responsible for the contract and debt; the applicable period, billing contact, due date, limit, and deposit are shown in the contract accepted by the owner. A recurring contract is provided according to the base terms set forth in the contract and adds no 3% fee to postpaid API usage. During that contract, manual prepaid top-ups by the account owner are also exempt from the top-up fee. A one-time contract has no subscription fee and adds a 3% fee plus VAT to postpaid API usage. API charges use the current model prices. Prepaid Credit is deducted first, and only the remaining amount is billed as postpaid usage. Deposit, limit, due date, suspension, and termination follow the approved contract; usage charges and unpaid invoices remain due after termination.

Article 8 (Escrow of Payment, etc. — Protection of Prepaid Means of Payment)

(1) Pursuant to Article 13(2), item 10 and Article 24 of the E-Commerce Act, the Company provides information on consumer protection measures for prepaid mail-order sales. Means of payment that are statutory exceptions, such as card payment and real-time account transfer, are not subject to the obligation to provide payment escrow or to subscribe to consumer damage compensation insurance.

(2) Because the Company does not offer virtual account deposit or bankbook-less deposit, which carry prepayment risk, as means of payment, the means of payment under Article 7(1) (credit and debit cards) are not subject to the obligation to provide payment escrow or to subscribe to consumer damage compensation insurance.

Article 9 (Credit — Closed-Loop Prepaid Voucher, Refund of Balance, and Validity Period)

(1) Credit is a prepaid means of payment issued by the Company exclusively for its own service, held by a Member who has paid in advance, and used solely to settle the fees for services provided directly by the Company (PleumRouter), such as integrated API routing to multiple AI models. Credit may not be used to purchase goods or services from, or to make payment to, any third party other than the issuing Company. Even where the Company brokers and integrates models of external AI model providers, the counterparty providing the Service and entering into the transaction with the Member is the Company, and no direct transactional relationship arises between the Member and the external provider.

(2) Credit may not be transferred, lent, or assigned to others, may not be transferred, merged, or aggregated between Members, and, except for the refund of unused Paid balance under paragraph (4) of this Article and Article 10, may not be withdrawn or exchanged for cash or exchanged for any other means of payment.

(3) Credits can only pay for the Company's service. They cannot be used for third-party transactions, transfers between Members, or cash withdrawals. Changes to their scope will be reviewed under applicable law.

(4) Discontinuation of one model alone does not trigger a refund of all unused credits. The Company refunds the applicable unused paid balance where it cannot provide the service and no reasonable alternative exists, or where law requires a refund.

(5) The validity period of charged Credit is one (1) year from the date of charging, and the validity period of Credit granted free of charge (First-Payment Bonus, referral bonuses, etc.) is thirty (30) days from the date of grant. The Company shall give notice of this a reasonable time before the validity period expires, and even after the validity period has elapsed, a Member may claim a refund under this Article and Article 10 until the commercial extinctive prescription is completed. These validity periods apply only to Credit charged or granted on or after October 2, 2026, and do not apply retroactively to Credit charged or granted before that date.

Article 10 (Withdrawal of Subscription and Refund Policy)

(1) The detailed standards and procedures for withdrawal of subscription and refund regarding Credit charging payments are set out in a separate Refund Policy; in the event of any conflict between these Terms and the Refund Policy, the Refund Policy shall prevail.

(2) Pursuant to Article 17(1) of the E-Commerce Act, a Member may withdraw their subscription with respect to unused Paid Credit within seven (7) days from the date of charging (payment) or the date the Credit was supplied. Unused balance after those seven (7) days is not eligible for self-serve refund; claims arising from causes attributable to the Company, service termination, overcharges, discrepancy in indication, or post-expiry refund requests are handled through the Refund Policy and the customer center.

(3) The following Credit is excluded from refund: (1) Credit already used and deducted through use of the Service; (2) Credit granted free of charge, such as a First-Payment Bonus or coupon. Pursuant to Article 17(6) of the E-Commerce Act, given the nature of a digital service whose use commences immediately upon charging, the Company clearly indicates, on the screen immediately preceding payment, that used and deducted Credit is not eligible for withdrawal or refund.

(4) Pursuant to Article 18(2) of the E-Commerce Act, the Company shall refund the payment within three (3) business days from the date it is notified of the withdrawal or refund request, and shall not claim any penalty or damages on the ground of withdrawal. A refund of a purchase made by card payment is, in principle, possible only through cancellation of the card sale. Where a Member has paid by credit card, the Company shall, pursuant to Article 18(3) of the same Act, without delay request the payment provider to suspend or cancel (in whole or in part) the charge.

(5) Where a Member requests subscription withdrawal or a refund for a payment, any bonus credit granted free of charge in connection with such payment, including the first-charge bonus (10% of charged credit, up to 5,000 credits), will be clawed back.

Article 11 (Tax Invoice, Receipt, and VAT)

(1) After the Member's business information has been verified, the Company issues electronic tax invoices for prepaid top-ups and confirmed postpaid invoices as required by law, and makes their status and documents available on the dashboard.

(2) VAT at 10% is calculated separately on API usage charges and postpaid fees. When paid subscriptions or service charges apply, the specific supply value, tax, and total are shown on the confirmed invoice and tax invoice.

(3) A Member may view and print payment receipts and transaction history at any time on My Page.

Article 12 (Obligations of the Member)

(1) A Member shall not engage in (1) misappropriating or fraudulently using another person's payment information or account, (2) using the API in an improper manner or interfering with the stable operation of the Service (DDoS, spam, fraud, etc.), (3) violating applicable laws, these Terms, or usage policies, such as by generating illegal content, or (4) sharing or transferring an issued API key to a third party without authorization.

(2) A Member bears responsibility for managing their own account and API key and is liable for any fraudulent use by a third party attributable to the Member. In the event of a violation of the prohibited acts, the Company may suspend or terminate the account.

Article 13 (Cancellation of Contract by a Minor)

(1) Pursuant to Article 13(3) of the E-Commerce Act, the Company notifies that where a minor enters into a use contract or charges Credit without the consent of a legal representative, the minor or the legal representative may cancel the contract.

(2) However, cancellation may be restricted where, for example, the minor used deception to make others believe they were an adult or that the legal representative's consent had been obtained.

Article 14 (Protection of Personal Information)

(1) The Company collects the minimum personal information necessary to provide the Service and protects it in accordance with the Personal Information Protection Act. Specific matters, such as the purpose, items, retention period, third-party provision, entrustment of processing (payment gateways, hosting providers, AI model providers, etc.), and the rights of data subjects, are set out in a separate Privacy Policy.

(2) The Company shall not use or provide personal information without a Member's consent or beyond the scope of consent. However, exceptions apply where required by applicable laws, such as performance of the contract, settlement of payments, and identity verification to prevent misappropriation.

(3) Email and account identifiers needed for registration are processed as necessary to perform the contract under Article 15(1)(4) of the Korean PIPA; no mandatory privacy consent is requested. Acceptance of these Terms and confirmation of age 14 or older are conditions of sign-up. Marketing, use of input for improvement, leaderboard disclosure, and any independent provider training or overseas transfer are requested separately when applicable. Optional consent can be refused or withdrawn in Settings without affecting other Service functions. Advertising emails are sent pursuant to Article 50 of the Network Act with an '(Advertisement)' prefix in the subject and an unsubscribe link in the body; a Member may refuse receipt at any time via the unsubscribe link or under 'Settings > Consent Management'. Non-advertising emails required for transactions, authentication, and notices continue to be delivered even after refusal.

(4) The Company sends request bodies to an AI model provider only after verifying its recipient, country, training use, retention, and overseas transfer basis. Article 28-8(1)(3) of the Korean PIPA is used only for outsourcing or storage necessary to perform the contract and disclosed in the Privacy Policy. Independent provider training or other use requires a separate lawful basis and optional consent. Unverified providers are excluded from new listing and routing.

(5) Without separate consent to use input for service improvement, the Company does not store request and response bodies and processes only metadata needed for billing and security. Storage without consent for enterprise or regulated profiles is suspended until an independent basis is verified.

(6) Pursuant to Article 28-2 of the Personal Information Protection Act, the Company may, for the purpose of improving service quality and conducting research (such as optimizing model routing), pseudonymize a Member's service usage data (replacing the account identifier with an irreversible pseudonymous key and not storing the input and response bodies) and use it for statistical compilation and scientific research purposes without the data subject's consent. Specific matters, such as the items and methods of processing pseudonymized information and measures to ensure safety, are set out in the Privacy Policy.

(7) Where a Member has consented to 'disclosure of a nickname on the token-usage leaderboard', pursuant to Articles 17 (provision to a third party) and 22 of the Personal Information Protection Act, the Company displays the Member's configured nickname (or a masked display derived from the email where none is set) together with the token-usage rank and statistics on the leaderboard of a public web page, thereby disclosing it to an unspecified number of visitors. This consent is optional and consenting does not affect use of the Service (however, the Member's rank is not displayed on the leaderboard without consent), and may be withdrawn at any time after sign-up under 'Settings > Consent Management'. Upon withdrawal, the Member's nickname and rank are immediately removed from the leaderboard. For the purpose of leaderboard display, the Company discloses no identifying information other than the nickname and rank (not email, account ID, or contact details), and the retention period is until consent is withdrawn or the Member withdraws membership. A child under the age of 14 may not consent to this item without the consent of a legal representative.

Article 15 (Disclaimer of the Company)

(1) The Company is not liable where it cannot provide the Service due to force majeure such as a natural disaster, war, suspension of service by a telecommunications carrier, or a power outage.

(2) The Company is not liable, absent its intent or gross negligence, for failures, response delays, or the accuracy, legality, or completeness of output results of third-party AI model providers connected or brokered through the Service, and the Member bears responsibility for the consequences of decisions made on that basis.

(3) The Company is not liable for usage failures attributable to the Member, damage caused by negligent management of an API key, or the outputs that the Member generates or uses through the Service.

Article 16 (Resolution of Disputes and Governing Law)

(1) The Company operates a customer center (support@pleum.ai) to handle Members' complaints and damages relating to the Service.

(2) For disputes not resolved through consultation between the parties, a Member may apply for dispute mediation to the Consumer Dispute Mediation Committee of the Korea Consumer Agency, the Electronic Commerce Dispute Mediation Committee, the Financial Supervisory Service, the Personal Information Dispute Mediation Committee, and the like.

(3) These Terms and disputes between the Company and Members are governed by the laws of the Republic of Korea, and the jurisdiction of litigation follows the Civil Procedure Act.
