Terms of Use

1. Acceptance of Terms

These Terms of Use ("Terms", "Agreement") constitute a legally binding contract entered into between you (whether personally, on behalf of an entity, or via automated means) ("User", "you", "your") and Client-Side PDF Tools Ltd. ("Company", "we", "us", or "our"). This Agreement governs your access to and use of the website located at https://clientsidepdftools.com, alongside any related applications, client-side scripts, and APIs (collectively, the "Service").

By accessing, browsing, or utilizing the Service in any capacity, you acknowledge that you have read, understood, and unconditionally agree to be bound by all the terms, conditions, and policies set forth herein. If you do not agree with all of these Terms, you are expressly prohibited from using the Service and must discontinue access immediately.

2. Eligibility

Access to the Service is restricted to individuals who possess the legal capacity to form a binding contract. By accessing the Service, you represent and warrant that you are at least eighteen (18) years of age, or the age of legal majority in your applicable jurisdiction. If you are accepting these Terms on behalf of a corporation, government entity, or other legal entity, you represent and warrant that you have the requisite authority to bind such entity to these Terms.

3. Definitions

• "Client-Side Processing" signifies that all computational operations execute entirely within the localized environment of the User's web browser, utilizing the User's proprietary hardware resources, without transmitting file payloads to remote servers.
• "User Content" encompasses any documents, texts, images, PDF files, or data inputs that a User loads, manipulates, or generates using the Service.
• "Malicious Code" means viruses, worms, time bombs, Trojan horses, and other harmful or malicious code, files, scripts, agents, or programs.

4. Scope of Services & Client-Side Processing Disclaimer

We provide a specialized suite of browser-based tools designed to manipulate, merge, split, view, and edit Portable Document Format (PDF) files. Our infrastructure is strictly architected upon a 100% client-side execution model.

4.1 Local Processing and Device Limitations

Files remain exclusively on your local device. Our application loads the necessary JavaScript libraries into your browser, and all subsequent file operations occur locally. Your files are never intentionally uploaded, transferred, or stored on our enterprise servers.

Because processing relies on your machine, performance is directly contingent upon your Local Device Limitations, specifically your available Random Access Memory (RAM), Central Processing Unit (CPU) speed, and browser architecture.

4.2 Large File Processing & Unsupported File Disclaimers

Browser memory is temporary and inherently restricted by the browser's executable sandbox limits (e.g., V8 engine memory limits). Processing large PDF files, documents with high-resolution images, or heavily encrypted files may exceed these limits, resulting in browser crashes, tab freezing, or out-of-memory errors. The Company accepts no liability for such interruptions.

We do not guarantee compatibility with all PDF structural variants. Malformed, non-standard, heavily encrypted, or corrupted files may be unsupported and fail to process.

4.3 Download and Backup Responsibility

You are solely responsible for saving and downloading your processed User Content before closing the browser tab or navigating away from the Service. As we do not hold your files, navigating away will result in the immediate and unrecoverable loss of the processed data in your browser's temporary memory. You are explicitly required to maintain local backups of all original documents prior to using the Service. We bear absolutely no responsibility for data loss, corruption, or destruction resulting from browser crashes, device failures, or user error.

5. User Responsibilities & Acceptable Use Policy

You are granted a limited, non-exclusive, non-transferable, and revocable license to access and use the Service strictly in accordance with this Agreement. You assume full responsibility for all activities, legal compliance, and consequences arising from your usage of the Service.

6. Prohibited Activities

To maintain the integrity and security of the Service, you strictly agree NOT to engage in any of the following Prohibited Activities:

• Illegal Activities: Using the Service for any purpose that violates applicable local, state, national, or international laws, regulations, or treaties.
• Intellectual Property Infringement: Processing, modifying, distributing, or forging User Content in a manner that misappropriates or infringes upon the copyright, trademark, patent, trade secret, or privacy rights of any third party.
• Malware and Abuse: Utilizing the Service to distribute Malicious Code, phishing scams, or fraudulent materials.
• Automated Extraction & Bot Attacks: Deploying automated systems, scrapers, headless browsers, spiders, or bots to access, scrape, or manipulate the Service, bypassing intended UI interactions.
• Reverse Engineering: Attempting to decompile, reverse engineer, disassemble, or derive the source code, proprietary algorithms, or underlying architecture of the Service.
• Security Circumvention: Probing, scanning, or testing the vulnerability of the Service infrastructure, or breaching security, authentication, or Client-Side execution limitations without explicit written authorization.
• Denial of Service (DoS): Intentionally imposing an unreasonable load on our infrastructure or attempting to disrupt the delivery of the Service web assets.

7. Intellectual Property Rights

Unless otherwise indicated, the Service is our proprietary property. All source code, databases, functionality, software, website designs, audio, video, text, photographs, graphics, icons, and branding (collectively, the "Company Content"), as well as the trademarks, service marks, and logos contained therein, are owned or controlled by us or licensed to us. They are protected by copyright and trademark laws of the United States, international copyright treaties, and other intellectual property rights. No part of the Service or Company Content may be copied, reproduced, aggregated, republished, uploaded, publicly displayed, encoded, translated, transmitted, distributed, sold, licensed, or otherwise exploited for any commercial purpose whatsoever without our express prior written permission.

8. User Content Ownership

Due to the client-side nature of our architecture, we do not claim ownership, access, or licensing rights to your User Content. You retain 100% of the intellectual property rights to the documents you process locally. We do not monitor, review, harvest, or utilize your User Content for training AI models, marketing, or any other purpose.

9. Copyright & DMCA Policy

We respect the intellectual property rights of others. Since User Content is never transmitted to or hosted on our servers, we generally cannot execute takedowns of specific processed files. However, if you believe that any material natively hosted on our domain (e.g., blog posts, site text, UI elements) infringes upon any copyright which you own or control, you may submit a notification pursuant to the Digital Millennium Copyright Act (DMCA) to our designated Copyright Agent at legal@clientsidepdftools.com.

10. Security Practices & Client-Side Execution

We implement enterprise-grade security protocols to protect the delivery of our application to your browser. These practices include, but are not limited to:

• Transport Layer Security (TLS/HTTPS): All connections to our domain are encrypted in transit to prevent interception.
• Security Headers: We enforce strict Content Security Policy (CSP), Strict-Transport-Security (HSTS), X-Content-Type-Options, X-Frame-Options, Permissions Policy, and Referrer Policy to mitigate cross-site scripting (XSS), clickjacking, and unauthorized resource loading.
• Browser Sandboxing: All JavaScript execution is confined within the strict security sandbox of modern web browsers, preventing unauthorized read/write access to your local file system beyond the specific files you explicitly select for processing.

While we secure the delivery mechanism, the ultimate security of the processed files depends entirely on the operational security of your local machine, operating system, and web browser. We do not warrant protection against malware residing on your local device.

11. Third-Party Services & Google AdSense Disclosure

The Service may contain links to third-party websites or services that are not owned or controlled by the Company. Furthermore, to provide this Service free of charge, we participate in third-party advertising networks, specifically Google AdSense and its approved third-party vendors.

11.1 Advertising, Cookies, and Compliance

In strict compliance with Google AdSense Publisher Policies, the Google EU User Consent Policy, and applicable privacy frameworks (including GDPR, UK GDPR, CCPA, CPRA, and LGPD), we disclose the following:

• Use of Cookies: Google and its third-party vendors utilize cookies and web beacons to serve advertisements based on a user's prior visits to our Service or other websites across the Internet.
• Personalized Ads & Non-Personalized Ads: Depending on your location and consent status, ads may be personalized or non-personalized. Personalized ads use your data to tailor the advertising experience.
• Consent Mode v2: For users within the European Economic Area (EEA), the UK, and regions requiring explicit consent, we deploy a verified Consent Management Platform (CMP) integrating Google Consent Mode v2. You retain full control to grant, deny, or withdraw consent for personalized advertising and non-essential cookies.
• Opt-Out Rights: Users may opt out of personalized advertising by visiting Google Ads Settings or by utilizing opt-out tools such as aboutads.info.

12. Privacy Policy & Cookies Reference

Your privacy is of utmost importance to us. This Agreement explicitly incorporates our Privacy Policy and Cookie Policy by reference. These policies detail our data collection practices, your rights regarding personal data, and our use of tracking technologies. By accessing the Service, you acknowledge and agree to the data practices described in those documents.

13. AI Generated Content Disclaimer

To the extent the Service incorporates any Artificial Intelligence (AI) algorithms, large language models (LLMs), or optical character recognition (OCR) functionalities (whether executed client-side via WebAssembly or otherwise) to summarize, translate, or extract text from your User Content, the output is provided "AS IS". AI-generated outputs may be inaccurate, incomplete, or misleading. The Company disclaims any liability for decisions made based upon AI-generated content.

14. Service Availability & Maintenance Windows

We endeavor to provide a reliable Service; however, we do not guarantee continuous, uninterrupted, or error-free operability. We reserve the right to perform scheduled maintenance, apply emergency patches, or completely suspend or terminate the Service without prior notice. Browser compatibility changes, web standard deprecations, or infrastructure outages may temporarily or permanently impair Service availability.

15. No Warranty & Disclaimer of Accuracy

THE SERVICE AND ALL RELATED COMPONENTS ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY EXPRESSLY DISCLAIMS ALL WARRANTIES, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ACCURACY.

We do not warrant that the Service will meet your specific requirements, that the PDF outputs will perfectly preserve vector graphics, complex formatting, or proprietary font encodings, or that the Service will operate safely in combination with any other hardware or software.

16. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE JURISDICTION, IN NO EVENT SHALL CLIENT-SIDE PDF TOOLS LTD., ITS AFFILIATES, DIRECTORS, EMPLOYEES, AGENTS, LICENSORS, OR PARTNERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES. THIS INCLUDES, BUT IS NOT LIMITED TO, DAMAGES FOR LOSS OF PROFITS, REVENUES, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO:

• Your access to, use of, or inability to access or use the Service;
• Any unauthorized access to or alteration of your local files, transmissions, or data;
• Browser crashes resulting in the loss of unsaved User Content;
• Any actions taken by third parties through the Service.

In no event shall our total, aggregate liability to you for all damages, losses, and causes of action—whether in contract, tort (including negligence), or otherwise—exceed the greater of fifty United States Dollars ($50.00 USD) or the total amount paid by you to us in the preceding six (6) months for the Service.

17. Indemnification

You agree to defend, indemnify, and hold harmless Client-Side PDF Tools Ltd., its affiliates, and their respective officers, directors, employees, contractors, and agents from and against any and all claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to: (a) your violation of these Terms; (b) your User Content; (c) your violation of any third-party rights, including intellectual property or privacy rights; or (d) any illegal or prohibited activity conducted through your use of the Service.

In particular, but without limitation, the Service may not be exported or re-exported (a) into any U.S. embargoed countries or (b) to anyone on the U.S. Treasury Department's list of Specially Designated Nationals or the U.S. Department of Commerce Denied Person's List or Entity List. By using the Service, you represent and warrant that you are not located in any such country or on any such list.

19. Governing Law & International Users

The Service is operated from facilities within the United States. We make no representation that the Service is appropriate or available for use in other locations. Those who access the Service from other jurisdictions do so on their own volition and are responsible for compliance with local laws.

This Agreement shall be governed by, construed, and enforced in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law principles and excluding the UN Convention on Contracts for the International Sale of Goods.

20. Arbitration & Class Action Waiver

Please read this section carefully as it affects your legal rights, including your right to file a lawsuit in court.

Any dispute, claim, or controversy arising out of or relating to these Terms or the breach, termination, enforcement, interpretation, or validity thereof, shall be determined by final and binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules, rather than in court. The seat of the arbitration shall be Wilmington, Delaware. The language to be used in the arbitral proceedings will be English.

CLASS ACTION WAIVER: You and the Company agree that any proceedings to resolve disputes will be conducted only on an individual basis and not in a class, consolidated, or representative action. If for any reason a claim proceeds in court rather than in arbitration, we each waive any right to a jury trial.

21. General Provisions

• Force Majeure: We shall not be held liable for any delay or failure in performance resulting directly or indirectly from acts of nature, forces, or causes beyond our reasonable control, including internet failures, computer equipment failures, telecommunication failures, electrical power failures, strikes, labor disputes, riots, insurrections, civil disturbances, shortages of labor or materials, fires, floods, storms, explosions, acts of God, war, governmental actions, orders of domestic or foreign courts or tribunals.
• Severability: If any provision of these Terms is found by a court of competent jurisdiction to be invalid, illegal, or unenforceable, such provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will remain in full force and effect.
• Entire Agreement: These Terms, together with our Privacy Policy and any other legal notices published by us, constitute the entire, complete, and exclusive agreement between you and the Company regarding the Service, superseding all prior agreements, understandings, or communications.
• Waiver: No waiver of any term of this Agreement shall be deemed a further or continuing waiver of such term or any other term. Our failure to assert a right or provision under these Terms shall not constitute a waiver of such right or provision.
• Assignment: You may not assign, delegate, or transfer these Terms or your rights or obligations hereunder, in any way (by operation of law or otherwise) without our prior written consent. We may transfer, assign, or delegate these Terms and our rights and obligations without consent.
• Survival: All provisions of this Agreement which by their nature should survive termination shall survive, including, without limitation, ownership provisions, warranty disclaimers, indemnity, and limitations of liability.

22. Electronic Communications

Visiting the Service, sending us emails, and completing online forms constitute electronic communications. You consent to receive electronic communications, and you agree that all agreements, notices, disclosures, and other communications we provide to you electronically, via email and on the Service, satisfy any legal requirement that such communication be in writing.

23. Changes to Terms

We reserve the unilateral right to amend, modify, or replace these Terms at any time, at our sole discretion. If a revision is deemed material, we will provide reasonable notice (e.g., an alert banner on the Website) at least thirty (30) days prior to the new terms taking effect. The determination of what constitutes a material change remains solely at our discretion. Your continued use of the Service following the effective date of any changes constitutes your binding acceptance of the updated Terms.
