Privacy

privacy boundary
Your files stay inside the browser tab.
PDF files often contain contracts, invoices, IDs, resumes and financial details. VaultPDF reads them in browser memory and creates downloads on your device.
The original file remains untouched. Clear the workspace or close the tab to release the files and generated results from the current session.
quality checks
Built-in safeguards around every local run.
Inputs are checked before processing, long tasks can be cancelled and generated files are kept within explicit browser memory limits.
| Area | What is checked | Where it runs | Control | Result |
|---|---|---|---|---|
| File input | Type and file signature | Browser local | Rejected before run | Unexpected files stay out |
| Long operations | Progress and cancellation | Web Worker | Cancel at any time | Interface stays responsive |
| Generated files | Count and memory limits | Browser memory | Old results are released | Latest output remains ready |
| Source files | Read-only workflow | Your device | New download only | Originals stay untouched |
