Privacy Policy — PDF Document Merger
Last updated: February 27, 2026
Overview
PDF Document Merger is a browser extension that merges PDF files entirely on your device. We do not collect, store, transmit, or have access to any of your data.
Data Collection
We do not collect any data. Specifically:
- No personal information (name, email, address, etc.)
- No usage analytics or telemetry
- No file contents or metadata
- No browsing history
- No cookies or tracking identifiers
- No crash reports
How the Extension Works
All PDF processing happens locally in your browser using client-side JavaScript libraries (pdf-lib, pdfjs-dist). Your PDF files are:
- Read into browser memory (RAM) when you add them
- Stored temporarily in your browser's IndexedDB (local storage on your device)
- Processed entirely on your device when you merge
- Never transmitted to any server, API, or third party
When you close the extension tab, all temporary data is cleared from memory.
Permissions
The extension requests the following browser permissions:
- activeTab — Access the current tab to detect PDF files
- storage — Store temporary file metadata locally in your browser
- contextMenus — Add "Add to PDF Merger" option to the right-click menu
- tabs — Communicate between extension tabs (workspace selection)
- scripting — Inject content script to detect PDF pages in the browser
- host_permissions (<all_urls>) — Required for scripting.executeScript to work on PDF pages
None of these permissions are used to collect or transmit data.
Network Requests
The extension makes zero network requests. It does not:
- Contact any server or API
- Send any data to third parties
- Load any external resources at runtime
- Include any analytics, advertising, or tracking scripts
The extension works fully offline after installation.
Third-Party Services
The extension does not use any third-party services, SDKs, or libraries that collect data. The only dependencies are open-source PDF processing libraries that run entirely in the browser.
Data Storage
All data is stored locally on your device:
- IndexedDB — Temporary storage for PDF file contents while you work
- chrome.storage.local — Minimal metadata (file names, page counts) for pending files
No data is synced to cloud services or shared across devices.
Children's Privacy
The extension does not collect any data from anyone, including children under 13.
Changes to This Policy
If this privacy policy changes, the updated version will be published at the same URL. Since the extension collects no data, significant changes are unlikely.
