Product: JTMetrics for GitHub
Last updated: March 22, 2026

This Privacy Policy explains how the JTMetrics for GitHub Chrome extension handles information.

What the extension does

The extension analyzes JavaScript/TypeScript source files from the GitHub repository page you open, computes metrics locally in your browser, and allows you to download a JSON results file.

Data we process

• Repository metadata and file contents requested from github.com and api.github.com for the repository you choose to analyze.
• The source path you type in the extension UI (for example, src).
• An optional GitHub token if you choose to provide one in extension options.

How data is used

• Only to fetch repository files, compute metrics, and generate downloadable JSON output for you.
• The extension does not use your data for advertising, profiling, or analytics.

Storage and retention

• The optional GitHub token is stored in Chrome extension storage (chrome.storage.sync).
• The source path is stored locally in browser storage per repository for convenience.
• Metric computation runs client-side. No project metrics are sent to our external servers.

Data sharing

We do not sell or transfer your data to third parties. Network requests are only made to GitHub endpoints required to read repository content.

Your controls

• You can remove the optional GitHub token at any time from extension options.
• You can clear browser extension storage to remove saved configuration values.
• You can uninstall the extension at any time.
