Fundamentally Secure by Design
We don't just promise not to look at your documents—our architecture makes it technologically impossible.
100% Local Execution
Every operation occurs within your browser's memory sandbox. Your CPU does the work, not ours.
Zero Server Uploads
No files are ever transmitted over the internet. No cloud processing, no temp files, no egress.
No Data Retention
When you close the tab, the data ceases to exist. We have no databases storing your sensitive information.
The Threat Model
Risk: Your confidential file travels across public ISP networks.
Risk: Files are saved to temporary cloud drives where they can be breached.
Risk: Companies scan files for metadata to sell to advertisers.
Code Delivery: We send our WebAssembly app to your browser.
Local Processing: You drop a PDF, and your own CPU processes it instantly in RAM.
Absolute Privacy: The file never left your hard drive.
Verify It Yourself
Don't trust marketing copy. You can easily verify our zero-data-egress claim using your browser's developer tools.
# 1. Open Chrome DevTools (F12 or Cmd+Option+I)
# 2. Go to the "Network" tab
# 3. Process a PDF file using any of our tools
