uJson is a browser extension that formats, validates, and beautifies JSON data. We are committed to protecting your privacy.
uJson does not collect, store, or transmit any personal data.
Specifically, we do NOT collect:
- Personal information (name, email, address, etc.)
- Browsing history
- Website content
- Usage analytics
- Any other user data
The extension uses browser local storage only to save your preferences:
- Theme settings (dark/light mode)
- Indentation options
- Other display preferences
This data is stored locally on your device and is never transmitted to any server.
All JSON formatting and processing happens entirely on your local device. No data is sent to external servers.
uJson does not use any third-party analytics, tracking, or data collection services.
The extension requires certain browser permissions to function:
- storage: Save your preferences locally
- activeTab: Access JSON content on the current page for formatting
- clipboardWrite: Allow copying formatted JSON to clipboard
- host_permissions: Detect JSON on any webpage
These permissions are used solely for the extension's core functionality.
If we make changes to this privacy policy, we will update the "Last updated" date above.
