RadioMatch

RadioMatch is a browser extension that recommends live internet radio stations based on your music taste on YouTube and YouTube Music. This policy describes exactly what data the extension processes, where it lives, and what never leaves your browser.

What stays in your browser

All of the following is stored locally using the browser's extension storage (chrome.storage.local) and is never uploaded:

• Listening history — the music tracks (artist and title) the extension has detected while you played them, with timestamps. Visible to you in the popup's History tab.
• Taste profile — an aggregated map of genre weights (for example drum and bass: 0.9, soul: 0.4) built from your listening over time.
• Saved and hidden stations — your favourites and the stations you marked "Not for me".

You can clear the history and the profile at any time with one click in the popup, and uninstalling the extension removes everything.

What reaches our server

The extension talks to our server (hkiug.com) in exactly three situations:

• Genre lookup — when a track has played for about 30 seconds (and tracking is enabled), the extension sends the artist name only — no track title, no timestamp, no user identifier — to convert it into genres.
• "Find matching live radio" — when you click the button, the artist name and track title of the currently playing song are sent to find matching stations.
• "Match my taste" — when you click the button, an anonymous map of genre weights (such as funk: 0.8) is sent. Your history and the artists behind the profile are not included.

Our server keeps a shared, anonymous cache of artist-to-genre mappings (artist name, genres, date). This cache contains no user identifiers and no track titles, and it cannot be connected to any individual user. Standard, short-lived web server logs may record the technical details of requests (such as IP addresses) for security and operations, as with virtually every website.

Third-party services

• MusicBrainz — our server queries the open MusicBrainz database to resolve artist names into genres. Only the artist name (and, for explicit matches, the track title) is included in the query. Your identity is never part of it.
• Radio Browser — station data (names, stream addresses, tags) comes from the open Radio Browser directory. No user data is involved.
• Radio streams — when you press play, your browser connects directly to the radio station's own stream server, exactly as if you had opened the stream yourself. The station sees a normal listener connection; we are not in between.

Your controls

• The "Build from my listening" switch in the popup turns all listening detection off. It is on by default and clearly shown; switching it off stops both history and profile collection immediately.
• Clear history and Clear profile erase the local data instantly.
• Uninstalling the extension removes all locally stored data.

Data retention

Local data stays in your browser until you clear it or uninstall the extension. The server-side artist–genre cache refreshes itself on a rolling 30-day cycle and contains no personal data.

Changes to this policy

If RadioMatch's data handling ever changes (for example if optional accounts are introduced), this page will be updated before the change ships, and the extension's store listing will reflect it.
