TL;DR
Your files never leave your device. We can't see them, we don't store them, we don't want them. Everything processes locally in your browser.
How FastTools Works
FastTools uses WebAssembly technology to process files entirely within your web browser. When you use our tools:
- Files are loaded into your browser's memory
- Processing happens on your device using your CPU
- Results are generated locally
- Files are never uploaded to any server
Data We Collect
File Data: None. Zero. Your files never touch our servers.
Analytics: We may collect anonymous usage statistics like:
- Which tools are used most
- General geographic region
- Browser type
- Page views
This data is anonymous and cannot identify you or your files.
Cookies
We use minimal cookies for basic functionality and analytics. No tracking cookies, no advertising cookies, no third-party cookies.
Third-Party Services
We may use:
- Analytics services (privacy-focused)
- CDN for loading libraries
None of these services have access to your files.
