Your Privacy Matters
Browser PDF converter is designed to minimize data exposure by running document operations in your browser.
How Processing Works
When you use a tool, selected files are processed locally by frontend scripts and libraries.
- File is loaded in browser memory
- Processing happens on-device
- No file content upload to processing servers
- No file content storage on our servers
- User controls file lifecycle locally
Data We Do Not Collect
Because processing is local, we do not collect file contents.
- Document contents
- Extracted text payloads
- Embedded media from user files
- Private annotations or signatures
Data We May Collect
We may collect anonymous product analytics for reliability and UX improvements.
- Anonymous page views
- Browser and device class
- General region-level location
- Performance and reliability metrics
- Referral and navigation events
We store limited anonymous conversion audit records in Cloudflare KV (`ANALYTICS_KV`) for service tracking (for example: tool, success or failure, file count, bulk mode, and timestamp). We do not store file contents, filenames, extracted text, passwords, or other sensitive document data in this analytics store.
