Last updated: February 26, 2026
This privacy policy applies to the Localhost App Detector Chrome extension (version 3.1.0+), published by GTM Enterprises LLC.
Summary
Localhost App Detector does not collect, transmit, or share any personal data. All data generated by the extension stays on your local machine inside your browser.
What Data the Extension Accesses
Localhost & 127.0.0.1 Traffic Only
The extension monitors network requests made to http://localhost/* and http://127.0.0.1/* exclusively. It does not observe, intercept, or record any traffic to external websites or domains.
Data Stored Locally
The extension stores the following data using Chrome’s built-in storage API (locally on your device):
- Localhost ports and URLs you have visited during a session
- Saved app configurations (names, ports, tags, notes, favorites) that you explicitly save
- Custom hostname mappings you manually configure
- Usage counts and last-accessed timestamps for saved apps
All stored data is kept entirely within your Chrome browser and is never transmitted to GTM Enterprises LLC or any third party.

Data Retention & Cleanup
