Free PDF Unlock

Privacy Policy

1. Overview

At Free PDF Unlock, we believe that your privacy is paramount. This Privacy Policy describes how we collect, use, and safeguard information when you visit and use our website. Unlike many online document services, our tool is built with a privacy-first architecture designed to minimize data collection and ensure that your documents remain completely confidential. By using our service, you agree to the practices described in this policy.

2. Files and Uploads

The primary purpose of our service is to process PDF files that you upload. We do not read, inspect, modify, or share the contents of your files for any purpose other than executing the specific function you request: removing permission restrictions. Your documents are treated as highly confidential, and we do not use your file data for machine learning training, marketing, profiling, or distribution to third parties.

3. Browser-Side Processing When Possible

Our tool is designed to utilize client-side (browser-based) processing where technologically feasible. For many standard PDF files, the decryption and restriction-removal process occurs entirely within your web browser using JavaScript. In these instances, your file never leaves your local device. It is processed in your local memory, ensuring absolute privacy since no data is transmitted to external servers.

4. Temporary Server-Side Processing

In cases where server-side processing is necessary due to document size, encryption complexity, or browser compatibility, the transfer and processing are strictly protected:

  • Secure Transmission: All files are uploaded using secure, industry-standard HTTPS (Hypertext Transfer Protocol Secure) encryption. This prevents interception of your data while in transit.
  • In-Memory Processing: Uploaded files are processed entirely in server memory. We do not write your files to temporary hard disk drives or persistent storage arrays during processing.

5. No Permanent File Storage

We enforce a strict zero-retention policy for all processed files. As soon as the restriction removal process is complete—whether successful or failed—the uploaded file and the processed output are immediately purged from our servers. We do not retain backup copies, archive files, or keep transaction logs that include your document content. Once you download your unlocked file or close your browser tab, the data is gone forever.

6. Web Analytics

To monitor website performance, understand user behavior, and diagnose technical issues, we use Google Analytics, a third-party web analytics service. Google Analytics collects standard, non-personally identifiable information such as:

  • IP addresses (masked or anonymized)
  • Browser type, operating system, and language settings
  • Pages visited, time spent on pages, and referring sites

This data is aggregated and used solely to improve our website's layout, speed, and overall usability. We do not link this analytics data with the files you upload or any individual identity.

7. Cookies and Local Storage

We use minimal cookies and local browser storage to support the website's functionality:

  • Analytics Cookies: Google Analytics sets cookies to distinguish unique users and throttle requests. You can disable cookies in your browser settings without affecting your ability to use our PDF tool.
  • Local State Storage: We may use your browser's local storage to temporarily preserve application state (such as file names or progress steps) during your session. This data remains on your device and is not sent to our servers.

8. Security Limitations

While we implement robust security practices (including HTTPS encryption, memory-only processing, and immediate data deletion), no method of transmission over the Internet or electronic storage is completely secure. We cannot guarantee absolute security against sophisticated external attacks, server intrusions, or network vulnerabilities. Users are encouraged to take standard security precautions when using web-based utilities.

9. User Responsibility

You are responsible for ensuring that you have the legal right, ownership, or authorized permission to modify any PDF file you upload to our service. Free PDF Unlock is a neutral utility provider; we do not verify the ownership of files and are not liable for any unauthorized modifications or breaches of copyright resulting from your use of this tool.
