Flag of Convenience

A ship registered abroad sails under a flag of convenience. A VPN does the same thing to your traffic — Flag of Convenience shows you which flag that is. The country your traffic appears to come from sits in your toolbar as its flag. One glance tells you whether the tunnel is up and where it comes out, and an optional notification fires the moment that country changes — which is usually the moment a VPN dropped. WHAT YOU GET • The exit country's flag as the toolbar icon, drawn edge to edge so it stays readable at 16 px. On Windows, where Chrome does not render flag emoji, a coloured country-code badge is used instead. • A popup with every exit address seen in the current check, what each source reported, and how many of them agreed. Click an address to copy it. • An optional notification when the exit country changes. • A history of the last 20 country changes, clearable at any time. • A ≠ badge when the sources see different countries on different addresses — a hint that part of your traffic is leaving outside the tunnel. • Checks every 1, 5, 15 or 60 minutes, at browser start, and when you open a new tab (at most one check every 30 seconds). HOW THE COUNTRY IS DECIDED Each check asks three independent public services in parallel — country.is, GeoJS and myip.com — and the country is decided by majority vote. This matters in practice: single services go down for hours, and behind a VPN pool two requests a second apart can leave through different addresses. A country backed by a majority is applied at once; one that merely went uncontested has to be confirmed by the next check, so the icon does not flicker while sources disagree. PRIVACY • No host permissions at all. The extension cannot read, modify or observe any page you visit — it has no access to your tabs' content, your history, your bookmarks or your form data, and it has no content scripts. • No telemetry, no developer server, no account, no identifier. Nothing leaves your device for the developer, ever. • Everything is stored in local extension storage: two settings, the current reading, and a capped list of country changes that holds countries and timestamps but never IP addresses. • Notifications are an optional permission, requested only if you tick the box.
