Privacy Policy

At MergePDFFilesFree.com, your privacy and document confidentiality are not afterthoughts; they are the architectural foundation of our platform. We believe users should never have to sacrifice confidentiality to perform routine document tasks. This Privacy Policy outlines how our 100% client-side platform functions, what data we do and do not collect, and how your privacy is mathematically protected.

1. Zero File Upload Policy (100% Client-Side In-Browser Execution)

Your files never leave your device or RAM. We use client-side JavaScript and WebAssembly to process documents exclusively within your browser's local execution memory. Unlike traditional web-based PDF converters that require users to transmit confidential files over public networks to remote cloud servers, MergePDFFilesFree guarantees that zero document bytes are ever uploaded or retained.

• Zero Server Transmission: Your files never travel across the internet to our servers or any third-party infrastructure.
• Zero Cloud Storage: We do not operate temporary file staging buckets, databases, or file-hosting servers.
• Immediate Memory Destruction: When document processing finishes and you initiate your download, temporary browser object URLs are immediately released and revoked using URL.revokeObjectURL(), allowing the browser’s automatic garbage collection to purge memory immediately.

2. No File-Tracking Cookies or Telemetry

We explicitly affirm:

• No Cookies for Files: Cookies are never used to track, fingerprint, or monitor the documents you process.
• No Document Content Telemetry: We do not log file names, page counts, metadata, text extracts, or file sizes.
• No Mandatory Accounts: You are never asked to create an account, register an email address, or provide personal payment credentials.

3. Compliance with Global Privacy Frameworks

By utilizing a zero-knowledge, client-side architecture, MergePDFFilesFree naturally aligns with the world's most stringent data privacy regulations:

• GDPR (General Data Protection Regulation): Under GDPR Article 25 ("Data protection by design and by default"), our system guarantees that personal data contained in your files is never collected, stored, or processed on external servers.
• HIPAA (Health Insurance Portability and Accountability Act): Because electronic Protected Health Information (ePHI) never leaves your local device memory, medical professionals can merge and organize records without violating HIPAA transmission rules.
• CCPA / CPRA (California Consumer Privacy Act): We do not sell, share, or monetize user personal information or document data.

4. Advertising & Third-Party Cookies (Google AdSense)

To maintain our complete suite of 24 PDF tools 100% free with no subscription paywalls, we partner with reputable third-party advertising vendors, including Google AdSense.

• Google and third-party vendors use cookies to serve ads based on prior visits to our website or other websites across the internet.
• Google's use of advertising cookies enables it and its partners to serve personalized or non-personalized ads to users based on their navigation history.
• File Isolation: Advertising scripts have zero access to browser memory variables handling your PDF files, which execute in an isolated execution scope.
• Users may opt out of personalized advertising by visiting Google Ads Settings or by configuring browser cookie settings.

5. Data Security & Browser Sandboxing

Your documents are secured by the security boundaries of your own web browser (Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge). Modern browsers isolate tab processes through operating system sandboxing, preventing external websites from inspecting memory.
