Terms of Service

Effective date: April 30, 2026Last revised: April 30, 2026

These Terms of Service ("Terms") form a legally binding agreement between you ("you", "your", "Customer", or "User") and PopcornSAR Co., Ltd. ("PopcornSAR", "we", "us", or "our"), a company duly organized under the laws of the Republic of Korea, governing your access to and use of PAIO and any related software, websites, applications, APIs, documentation, and services (collectively, the "Service").

By creating an account, starting a Free Trial, purchasing a subscription, or otherwise using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy and Refund Policy. If you do not agree, you must not access or use the Service.

1. Definitions

  • "Account" means the user account you create to access the Service.
  • "Free Trial" means the thirty (30) day evaluation period described in Section 5.
  • "Order" means any subscription order, purchase, or activation submitted through the Service or in writing.
  • "Paddle" means Paddle.com Market Limited and/or its affiliates, our authorized reseller and Merchant of Record for international transactions (see Section 7.1).
  • "Toss Payments" means Toss Payments Co., Ltd. (토스페이먼츠 주식회사), our authorized payment gateway provider for Korean Won transactions (see Section 7.2).
  • "Subscription" means a paid right to access the Service for a defined period (monthly, annual, or otherwise as stated in your Order).
  • "On-Premise License" means an Enterprise license under which PAIO software is installed on your own infrastructure under a separately negotiated agreement.

2. Eligibility and Account Registration

2.1 The Service is intended for use by individuals who are at least eighteen (18) years of age and by businesses, organizations, and their authorized representatives. By using the Service, you represent and warrant that you meet these requirements.

2.2 You must provide accurate, current, and complete information when creating your Account, and keep it up to date. You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your Account.

2.3 You must notify us promptly at contact@popcornsar.com of any unauthorized use of your Account or any other suspected breach of security.

3. The Service

3.1 PAIO is a software-as-a-service tool provided by PopcornSAR. The exact features and functionality available depend on your subscription plan and may be updated, modified, or discontinued from time to time at our reasonable discretion.

3.2 We will use commercially reasonable efforts to make the Service available, but the Service is provided on an "as available" basis. We do not guarantee uninterrupted or error-free operation. Scheduled maintenance, updates, or unforeseen outages may temporarily limit availability.

4. Subscription Plans

4.1 Plan Types. We offer the following plans, the specifics of which are described on our website or in your Order:

  • Monthly Subscription: billed on a recurring monthly basis.
  • Annual Subscription: billed on a recurring annual basis.
  • Free Trial: a thirty (30) day no-cost evaluation period (see Section 5).
  • Enterprise On-Premise License: a separately negotiated Enterprise plan under which PAIO is deployed in your environment. Enterprise On-Premise Licenses are governed by a separate written agreement that, in case of conflict with these Terms, prevails.

4.2 Term and Renewal. Subscriptions begin on the date payment is received and continue for the period stated in your Order. Subscriptions do not automatically renew through Paddle's auto-billing for Free-Trial-converted accounts unless explicitly enabled. For paid Subscriptions configured to auto-renew, renewal will occur at the then-current rate unless you cancel before the renewal date.

4.3 Cancellation. You may cancel your Subscription at any time through your Account settings or by contacting contact@popcornsar.com. Upon cancellation, you will retain access to the Service until the end of the then-current billing period. Cancellation does not entitle you to a refund except as set out in our Refund Policy.

5. Free Trial

5.1 We offer a thirty (30) day Free Trial of PAIO. The Free Trial begins when you activate your Account and ends thirty (30) days later or earlier if your usage is suspended for breach of these Terms.

5.2 No Automatic Conversion to Paid. Unlike many SaaS products, our Free Trial does not automatically convert into a paid Subscription. At the end of the Free Trial, your access to PAIO will be limited or suspended until you actively elect to purchase a paid Subscription and complete payment. No charge will be made to any payment method on file unless and until you affirmatively place an Order for a paid Subscription.

5.3 We reserve the right to modify, suspend, or terminate the Free Trial program at any time without prior notice.

6. Fees, Taxes, and Payment

6.1 Fees. Fees for paid Subscriptions are stated on our website or in your Order at the time of purchase. All fees are quoted exclusive of applicable taxes unless otherwise stated.

6.2 Taxes. You are responsible for all applicable sales, use, value-added (VAT), goods and services (GST), withholding, or similar taxes assessed on your purchase, except for taxes based on PopcornSAR's net income. Where Paddle acts as Merchant of Record (Section 7.1), Paddle collects and remits applicable consumption taxes on our behalf. For purchases settled through Toss Payments (Section 7.2), PopcornSAR is the seller of record and will collect applicable Korean VAT and issue tax invoices in accordance with Korean tax law.

6.3 Currency. Fees are billed in the currency stated at checkout. Payments made in foreign currency may be subject to bank or card-issuer conversion fees, for which you are solely responsible.

6.4 Late Payment. If a payment is not received when due, we may suspend or terminate your access to the Service until payment is made.

7. Payment Processors

PAIO Subscription payments are processed through one of two providers depending on your location and chosen payment method:

7.1 Paddle (Merchant of Record — International)

7.1.1 Online payments for PAIO Subscriptions made by international customers (including, but not limited to, customers outside the Republic of Korea) are processed by Paddle.com Market Limited ("Paddle"), our authorized reseller and Merchant of Record.

7.1.2 This means that when you purchase a Subscription via Paddle, Paddle, not PopcornSAR, is the seller of record for that transaction and is responsible for the collection and remittance of applicable sales taxes/VAT/GST, and for handling chargebacks and certain payment-related disputes.

7.1.3 By placing an Order through Paddle, you also agree to Paddle's Buyer Terms and Privacy Policy, available at https://www.paddle.com/legal. PopcornSAR remains your contracting party for the provision and operation of the Service itself.

7.2 Toss Payments (Payment Gateway — Republic of Korea)

7.2.1 For customers paying in Korean Won (KRW) or otherwise routed to our Korean checkout, payments are processed through Toss Payments, our authorized payment gateway in the Republic of Korea.

7.2.2 Unlike Paddle, Toss Payments acts as a payment gateway only. PopcornSAR is the direct seller of record for transactions settled through Toss Payments. PopcornSAR will collect and remit applicable Korean VAT and issue tax invoices (세금계산서) and cash receipts (현금영수증) in accordance with Korean tax law.

7.2.3 By placing an Order through Toss Payments, you also agree to the Toss Payments Service Terms applicable to buyers, available at https://www.tosspayments.com/terms.

7.3 No Direct Card Storage

PopcornSAR does not directly collect, store, or process your full credit card or bank account details. All such information is handled by Paddle, Toss Payments, and their respective sub-processors in accordance with PCI-DSS and applicable laws.

7.4 Choice of Processor

The payment processor used for your purchase is determined by the checkout flow you choose, your billing country, and the payment method offered. The processor handling your transaction is disclosed at checkout and on the resulting receipt or invoice.

8. Refunds

You may be entitled to a refund as set out in our Refund Policy, which forms an integral part of these Terms. Without limiting that policy:

  • Paid Subscriptions are eligible for a 14-day full refund from the date of the initial purchase, subject to the terms and exclusions described in the Refund Policy.
  • Free Trials cannot be refunded because no payment is collected.
  • Enterprise On-Premise Licenses are subject to the refund and termination terms set out in the relevant separately negotiated agreement.

For refund requests, contact contact@popcornsar.com.

9. Acceptable Use

9.1 You agree not to, and not to permit any third party to:

  • (a) reverse engineer, decompile, or attempt to extract the source code of the Service, except to the extent expressly permitted by applicable law;
  • (b) copy, modify, distribute, sell, sublicense, or commercially exploit the Service except as expressly permitted under these Terms;
  • (c) use the Service to transmit malware, conduct denial-of-service attacks, scan for vulnerabilities, or otherwise interfere with the Service or other users;
  • (d) use the Service in violation of any applicable law, regulation, or third-party right, including intellectual property and privacy rights;
  • (e) circumvent any access controls, usage limits, or authentication mechanisms; or
  • (f) use the Service to develop a competing product.

9.2 We may suspend or terminate your access to the Service immediately if we reasonably believe you have violated this Section 9.

10. Intellectual Property

10.1 Our IP. PopcornSAR and its licensors retain all right, title, and interest in and to the Service, including all software, documentation, branding, and underlying technology. No rights are granted to you except for the limited license expressly described in these Terms.

10.2 Your Data. You retain all rights to data and content that you upload, submit, or generate through the Service ("Customer Data"). You grant PopcornSAR a limited, non-exclusive, worldwide license to host, process, transmit, and display Customer Data solely as necessary to provide and improve the Service and to comply with legal obligations.

10.3 Feedback. If you provide suggestions, ideas, or feedback regarding the Service, you grant PopcornSAR a perpetual, irrevocable, royalty-free, worldwide license to use and incorporate such feedback into the Service without obligation to you.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, IN WHICH CASE SUCH EXCLUSIONS APPLY TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW.

12. Limitation of Liability

12.1 TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

12.2 EXCEPT FOR LIABILITY ARISING FROM YOUR PAYMENT OBLIGATIONS, BREACH OF SECTION 9 (ACCEPTABLE USE), OR INFRINGEMENT OF THE OTHER PARTY'S INTELLECTUAL PROPERTY, EACH PARTY'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS WILL NOT EXCEED THE FEES PAID OR PAYABLE BY YOU TO POPCORNSAR FOR THE SERVICE DURING THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

12.3 Some jurisdictions do not allow the limitation or exclusion of certain liabilities. To the extent any such limitation is unenforceable, our liability is limited to the maximum extent permitted by law.

13. Indemnification

You agree to defend, indemnify, and hold harmless PopcornSAR, its affiliates, and their respective officers, directors, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your breach of these Terms; (b) your Customer Data; or (c) your violation of any applicable law or third-party right.

14. Termination

14.1 You may terminate your Account at any time as described in Section 4.3.

14.2 We may suspend or terminate your access to the Service immediately, with or without notice, if (a) you breach these Terms, (b) we are required to do so by law, or (c) the provision of the Service to you becomes commercially impracticable.

14.3 Upon termination, your right to access and use the Service ceases. Sections that by their nature should survive termination (including Sections 6, 8, 10, 11, 12, 13, 14.3, 15, and 16) will survive.

15. Governing Law and Dispute Resolution

15.1 These Terms are governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict-of-laws rules.

15.2 Any dispute arising out of or in connection with these Terms shall first be addressed through good-faith negotiations. If the dispute cannot be resolved within thirty (30) days, it shall be submitted to the Seoul Central District Court of the Republic of Korea as the court of first instance, except that you (if a consumer) may have the right under your local law to bring proceedings in the courts of your country of residence.

15.3 Nothing in this Section 15 limits any non-waivable rights you may have as a consumer under the law of your country of habitual residence.

16. Miscellaneous

16.1 Entire Agreement. These Terms, together with our Privacy Policy and Refund Policy, constitute the entire agreement between you and PopcornSAR regarding the Service and supersede any prior agreements.

16.2 Changes to the Terms. We may update these Terms from time to time. If we make material changes, we will notify you by email or through the Service at least fourteen (14) days before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms.

16.3 Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.

16.4 Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions will continue in full force and effect.

16.5 No Waiver. Failure to enforce any right under these Terms is not a waiver of that right.

16.6 Force Majeure. Neither party will be liable for any failure or delay in performance caused by events beyond its reasonable control, including natural disasters, war, terrorism, civil unrest, government action, labor disputes, internet or power outages, or pandemic.

16.7 Notices. Notices to PopcornSAR must be sent to contact@popcornsar.com. Notices to you may be sent to the email address associated with your Account.
