Terms of Service

1. Introduction

These Terms of Service ("Terms") in conjunction with our Privacy Policy and Data Processing Agreement ("DPA") are the entire agreement ("Agreement") between The Plain Works Inc. (주식회사 더플레인웍스), a Korean corporation ("PaperJSX," "Company," "we," "us") and you ("Customer," "you"). These Terms govern your use of our website and services at paperjsx.com (collectively, the "Service").

By (a) creating an account, (b) purchasing access to the Service, or (c) clicking a button or checkbox indicating acceptance, you agree to be bound by this Agreement. If you are entering into this Agreement on behalf of an organization, you represent that you have the authority to bind that organization.

If you do not agree to this Agreement, do not use the Service.

2. Communications

By creating an account, you agree to receive transactional communications related to the Service (such as order confirmations, security alerts, and service notifications). We may also send product updates or announcements. You may opt out of non-transactional communications at any time by following the unsubscribe link or emailing support@paperjsx.com.

3. Accounts

When you create an account with us, you guarantee that the information you provide is accurate, complete, and current at all times. Inaccurate, incomplete, or obsolete information may result in the suspension or termination of your account.

You are responsible for maintaining the confidentiality of your account credentials, including API keys, and for all activity that occurs under your account, whether or not authorized by you. You must notify us immediately at support@paperjsx.com upon becoming aware of any breach of security or unauthorized use of your account.

You may not use as a username the name of another person or entity without appropriate authorization, or any name that is offensive or obscene. One person or entity may not maintain more than one free account.

We reserve the right to refuse service, terminate accounts, remove or edit content, or cancel orders at our sole discretion.

4. The Service

PaperJSX is a document generation engine. It converts structured JSON into native, editable office files — PowerPoint (.pptx), Word (.docx), and PDF — with embedded Excel charts, master slide inheritance, and deterministic layout. The Service is available as a cloud API, MCP server integrations, and a self-hosted SDK.

The open-source package @paperjsx/lite is licensed under the MIT License and governed by its own license terms. These Terms apply to the cloud-hosted Service (API, MCP tools, dashboard) and the commercial SDK packages. They do not apply to your use of @paperjsx/lite under the MIT License, except where you use it in connection with the cloud Service (e.g., authenticating against the API).

We may modify, update, or discontinue any part of the Service at any time. If we make changes that materially reduce the core functionality of a paid plan during its current billing period, we will provide reasonable advance notice and, where appropriate, a prorated credit or refund. We do not guarantee any specific level of availability or uptime unless separately agreed in writing.

5. Free Tier and Usage-Based Pricing

We offer limited access to the Service without payment ("Free Tier"). Free Tier accounts are subject to usage limits (including a monthly document generation cap) and feature restrictions as described on our pricing page.

Certain plans are billed on a usage basis (e.g., per document generated) rather than or in addition to a fixed Subscription fee. Usage-based charges are calculated based on your actual consumption during each Billing Cycle and invoiced through Paddle. Usage details are available in your account dashboard.

At any time and without notice, we reserve the right to (i) modify the features, limits, or availability of the Free Tier, (ii) discontinue the Free Tier, or (iii) require conversion to a paid plan if usage exceeds Free Tier limits. Features labeled "beta" or "preview" may be modified, limited, or discontinued at any time without advance notice.

6. Purchases and Payment

If you purchase a paid plan ("Subscription"), you may be asked to supply certain information relevant to your purchase, including payment method details. You represent and warrant that you have the legal right to use the payment method provided and that the information you supply is accurate.

Payments are processed by Paddle.com Market Limited ("Paddle"), our Merchant of Record. Paddle handles billing, invoicing, sales tax, VAT, GST, and payment processing on our behalf. By purchasing a Subscription, you also agree to Paddle's terms of service and privacy policy. We do not store complete payment card information.

We reserve the right to refuse or cancel your order for any reason, including product or service availability, errors in pricing or description, or suspected fraud.

7. Subscriptions and Billing

Subscriptions are billed in advance on a recurring basis ("Billing Cycle"), either monthly or annually depending on the plan you select. At the end of each Billing Cycle, your Subscription renews automatically under the same conditions unless you cancel through your account settings or by contacting us.

If automatic billing fails, we may issue an invoice requiring manual payment within a specified deadline. We may suspend access to the Service for any account with overdue payments. Overdue amounts accrue interest at 1.5% per month (or the maximum rate permitted by law, if lower).

8. Fee Changes

We may modify Subscription fees at any time. Any fee change will become effective at the end of your current Billing Cycle. We will provide at least 30 days' advance notice of any price change. Your continued use of the Service after the fee change takes effect constitutes agreement to pay the modified fee. If you do not agree, you may cancel your Subscription before the change takes effect.

9. Refunds

If you are not satisfied with the Service, you may request a refund within 14 days of your initial purchase or renewal by emailing support@paperjsx.com. Refunds are processed through Paddle. We reserve the right to deny refund requests that indicate abuse of this policy. Except as stated in this section or as required by applicable law, paid Subscription fees are non-refundable.

10. Content

The Service allows you to submit data through our API, MCP tools, or SDK, including structured JSON input, presentation templates (.potx), document templates, images, and related materials ("Customer Content"). You are responsible for all Customer Content submitted through the Service, including its legality, reliability, and appropriateness.

By using the Service, you represent and warrant that: (i) you have the right to submit all Customer Content, (ii) your use of the Service does not violate the privacy rights, publicity rights, copyrights, contract rights, or any other rights of any person or entity.

You retain all rights to your Customer Content and to the documents generated from it. You grant us a limited, non-exclusive, worldwide license to use, process, and store your Customer Content solely to the extent necessary to provide the Service. For API and MCP requests, input data and generated output are processed transiently and not retained after delivery unless you explicitly opt into storage features. This license ends when you delete your Customer Content or close your account.

Self-Hosted SDK. If you use the self-hosted SDK, Customer Content is processed entirely on your own infrastructure. We do not receive, access, or store Customer Content processed through the self-hosted SDK. Our data processing obligations under this Agreement and the DPA apply only to data processed through the cloud-hosted Service.

We have the right but not the obligation to monitor Customer Content to ensure compliance with these Terms and applicable laws. We may remove or refuse to process Customer Content that violates these Terms.

11. Acceptable Use

You may use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

(a) Use the Service in any manner that could disable, overburden, damage, or impair the Service or interfere with any other party's use of the Service.

(b) Introduce any viruses, trojan horses, worms, logic bombs, or other material that is malicious or technologically harmful.

(c) Attempt to gain unauthorized access to, interfere with, damage, or disrupt any parts of the Service, the servers on which the Service is hosted, or any server, computer, or database connected to the Service.

(d) Reverse engineer, decompile, or disassemble the Service, except to the extent expressly permitted by applicable law.

(e) Circumvent, disable, or interfere with usage limits, rate limiting, authentication mechanisms, or other technical measures of the Service.

(f) Resell, sublicense, or redistribute access to the Service without our prior written consent.

(g) Use the Service to store or transmit content that infringes any third-party intellectual property rights.

(h) Use automated means to create accounts or generate artificial usage.

(i) Attack the Service via a denial-of-service attack or distributed denial-of-service attack.

Violation of this section is a material breach. We may immediately suspend access to address security threats, suspected abuse, or legal compliance, with notice as soon as practicable. We may terminate access for material breach (with 14 days to cure, where curable), or suspend for nonpayment.

12. Intellectual Property

The Service and its original content (excluding Customer Content), features, and functionality are and will remain the exclusive property of The Plain Works Inc. and its licensors. The Service is protected by copyright, trademark, and other laws of the Republic of Korea and foreign countries. Our trademarks and trade dress may not be used in connection with any product or service without the prior written consent of The Plain Works Inc.

12A. Open Source Components

The Service incorporates open-source software components, including @paperjsx/lite, which is distributed under the MIT License. Nothing in these Terms limits your rights under applicable open-source licenses. To the extent any open-source license conflicts with these Terms, the open-source license governs solely with respect to that component.

12B. SDK License

If you purchase an SDK plan, we grant you a limited, non-exclusive, non-transferable license to install and use the commercial SDK packages on your own infrastructure for the number of projects or developers specified by your plan. You may not distribute, sublicense, or make the SDK available to third parties outside your organization. The SDK license is subject to your continued payment of the applicable fees and compliance with these Terms. Upon termination, you must cease use of the SDK and delete all copies.

13. Feedback

You may provide us with information and feedback concerning errors, suggestions for improvements, ideas, problems, complaints, and other matters related to the Service ("Feedback"). You acknowledge and agree that: (i) you shall not retain, acquire, or assert any intellectual property right or other right, title, or interest in or to the Feedback; (ii) we may have development ideas similar to the Feedback; (iii) Feedback does not contain confidential information or proprietary information from you or any third party; and (iv) we are not under any obligation of confidentiality with respect to the Feedback. You grant us a perpetual, irrevocable, non-exclusive, royalty-free, worldwide license to use Feedback for any purpose without obligation to you.

14. Usage Data

We collect aggregated and anonymized usage data generated by your use of the Service ("Usage Data"), including API call volumes, feature usage patterns, error rates, and performance metrics. We own all rights in Usage Data and may use it to operate, improve, and develop the Service, provided that such data does not identify you or any individual.

Each party will protect the other's confidential information and not disclose it to third parties without prior written consent, except as needed to perform under this Agreement or as required by law.
