Geo Flags by Max P.

The extension adds a country flag icon that helps you see where the server hosting the webpage is located, along with the IP and location information of all the domains that the page sends requests to.

All lookups happen locally - no data ever leaves the browser, and the extension makes no calls to external services on its own. The GeoIP database is downloaded once and stored on your machine.

The "Access your data for all websites" permission is required so the extension can see network requests and extract IP addresses from them. It does not access or modify web page content or anything like that.
