Refrigerant PT Chart Chrome extension: privacy policy

Last updated: October 29, 2026

This policy covers the Refrigerant PT Chart extension for Google Chrome. The website has its own privacy policy.

The short version

The extension collects no data. It does not collect, store, send, sell, or share any personal or usage information.

No network requests. All refrigerant data and calculations are built into the extension and run on your device. It works offline.
No tracking. No analytics, cookies, advertising IDs, or remote code.
No permissions. The extension asks for no browser permissions and cannot read the pages you visit.
Saved on your device only. Your last unit choice (°F/°C, psig/kPa/bar), tab and refrigerant are saved in the extension's local storage on your computer so the popup opens the way you left it. This never leaves your device, and removing the extension deletes it.
Links. If you click a link to RefrigerantPTChart.com, that page opens in your browser and the website's privacy policy applies. Links include utm_source=chrome-extension so we can see in aggregate how many visits come from the extension; nothing identifies you.

Estimates for reference only; verify with manufacturer data.

If this policy changes, we will update this page and the date above. Questions: [email protected].
