Privacy Policy

Last updated: April 14, 2026

Simple JSX Viewer is a Chrome extension that previews JSX components entirely within your browser. It is built with privacy as a core principle.

Data Collection

Simple JSX Viewer does not collect, store, transmit, or share any personal data or browsing information. Specifically:

• No analytics or tracking of any kind
• No cookies or local storage used by the extension
• No user accounts or sign-ins
• No telemetry, crash reports, or usage statistics

Permissions

The extension requests no browser permissions. It cannot access your tabs, browsing history, bookmarks, or any other browser data.

Network Requests

Simple JSX Viewer operates fully offline. All libraries (React, ReactDOM, Sucrase) are bundled within the extension. The only network request the extension ever makes is when you explicitly paste a URL and click Load to fetch a remote JSX file. No data is sent to any server in that process — the extension only downloads the file you requested.

Code Execution

JSX code you load is transpiled and rendered inside a sandboxed iframe that is isolated from the extension context and your browser. Your code never leaves your machine.

Third-Party Services

This extension uses no third-party services, APIs, CDNs, or external resources.

Changes to This Policy

If this policy is ever updated, the changes will be reflected on this page with an updated date.
