Privacy Policy
Last updated March 30, 2026
Overview
JSON Formatter & Query is a browser extension that formats and beautifies JSON responses directly in your browser. This privacy policy explains how the extension handles your data.
Data Collection
We do not collect, store, transmit, or share any user data. The extension:
- Does not collect personally identifiable information
- Does not collect browsing history or web activity
- Does not use analytics, tracking, or telemetry
- Does not make any network requests
- Does not use cookies
- Does not communicate with any external servers
How the Extension Works
The extension operates entirely within your browser:
- It detects when a browser tab displays a JSON response
- It formats and renders the JSON as an interactive tree view
- It provides a local query engine (Path, SQL, MongoDB-style) to search and filter the displayed JSON data
All processing happens locally on your device. No data ever leaves your browser.
Local Storage
The extension uses your browser's localStorage to save UI preferences such as:
- Selected theme (dark/light)
- Query panel dock position (bottom, top, left, right)
- Query panel size
These preferences are stored locally on your device and are never transmitted externally.
Permissions
The extension requires the <all_urls> host permission in content_scripts solely to detect JSON responses on any URL. This permission is used exclusively for content detection and formatting — no data is read, collected, or transmitted.
Third-Party Services
This extension does not integrate with or send data to any third-party services.

If this privacy policy is updated, the changes will be reflected in this document with an updated date.
