ZERO-UPLOAD PRIVACY GUARANTEE

Privacy Policy

Last updated: September 2026

Our Fundamental Privacy Commitment

At ExtractFiles (https://extractfiles.online), privacy is not a marketing checkbox—it is the foundational architectural principle upon which our tool was built. Unlike traditional online file utilities that require uploading your documents to remote cloud servers, ExtractFiles does not upload your files to our server.

1. How Client-Side Processing Works

When you select or drag-and-drop an archive (ZIP, RAR, 7Z, or TAR) into ExtractFiles:

  • The archive file is loaded directly from your device storage into your browser's local memory using the HTML5 File API and ArrayBuffer streams.
  • Decompression algorithms execute on your device CPU using WebAssembly (WASM) inside an isolated Web Worker background thread.
  • Extracted files are converted to local in-memory Blob URLs (blob:https://...) that exist solely within your browser tab session.
  • When you close the tab, refresh the page, or click «Close Archive», the in-memory Blobs and Web Worker instances are immediately terminated and memory is released.

2. Information We Never Collect

Because processing occurs exclusively inside your browser sandbox, we never have access to, receive, or store:

  • The contents of any file inside your archives.
  • The names, extensions, or directory structures of your files.
  • Any passwords or passphrases entered to unlock encrypted archives.
  • Temporary file copies or metadata caches.

3. Web Analytics and Server Logs

Our hosting provider maintains standard HTTP web server logs (such as requesting IP address, browser User-Agent, and requested page URL) solely for basic operational reliability, DDoS defense, and infrastructure performance. These web server logs do not and cannot contain your file data because your file data is never sent in HTTP requests.

4. Cookies and Local Storage

ExtractFiles does not use advertising or tracking cookies. We utilize browser localStorage solely to remember your chosen visual theme (light or dark mode) so your preference persists across visits.

5. Third-Party Services

We do not embed third-party advertising tracking pixels, social media tracking widgets, or invasive behavioral scripts. All core decompression routines run from self-hosted static WebAssembly binaries served directly from our domain.
