Privacy Policy

Your privacy is our top priority. Here's exactly how we protect it.

Last updated: August 2025

Local Processing

All PDF optimization happens directly in your browser using WebAssembly technology. Your files are processed in memory and never transmitted to any server. When you close the page, all data is automatically discarded.

No Tracking

We don't use any analytics, cookies, tracking pixels, or third-party scripts. We have no way to identify you or track your behavior across sessions. Your usage is completely anonymous.

No Data Storage

We don't store, cache, or retain any of your files or personal information. Everything happens in your browser's temporary memory and is automatically cleared when you navigate away or close the tab.

Hosting Disclosure

This website is hosted on Vercel's content delivery network. While we don't collect any data about you, Vercel may collect basic analytics such as:

  • Page views and visit counts
  • General geographic location (country/region level)
  • Browser type and device information
  • Referrer information (which site you came from)

Important: No file content, personal data, or detailed usage information is ever transmitted to Vercel or any other service.

Technical Implementation

Our PDF optimizer uses:

  • WebAssembly for high-performance local processing
  • Web Workers to prevent browser blocking
  • Client-side JavaScript with no server communication
  • Temporary blob URLs that are automatically revoked
