YT Music Live BPM — Privacy Policy

What this extension does

YT Music Live BPM adds a small overlay on music.youtube.com showing the detected tempo (BPM) of the track currently playing, plus a short graph of how that tempo has changed over the last couple of minutes.

Data collection

This extension does not collect, store, or transmit any data.

• Audio is processed temporarily in your browser. It is not recorded, stored, or sent anywhere.
• No video or page content is recorded, stored, or transmitted.
• No analytics, telemetry, or tracking of any kind is used.
• The extension does not access cookies, browsing history, or account information.
• No network requests are made by the extension itself.

How it works

All processing happens locally, inside your browser tab. The extension reads audio directly from the page's own player through the standard Web Audio API and estimates tempo with a simple on-device beat-detection algorithm. Nothing leaves your device.

Permissions

The extension only requests access to music.youtube.com, and only to attach an audio analysis node to the page's existing player and render the overlay. No other site or browser data is accessed.

Changes to this policy

If this extension's behavior ever changes to collect or transmit data, this page will be updated first and the extension's store listing will note the change.
