Last updated: 2026-10-08

Looper (the "Extension") is a browser extension that adds an A-B loop, metronome and tempo detection to YouTube video pages.

1. Data we collect

The Extension does not collect, store, transmit or sell any personal or browsing data. It has no servers and uses no third-party analytics.

2. Audio analysis

The "Auto detect" and "Beat sync" features read the audio of the video that is currently playing in order to estimate tempo and beat positions. This analysis happens entirely and in real time inside your browser. Audio is never recorded, stored or uploaded anywhere.

3. Locally stored settings

The Extension only remembers the following in your browser's local storage: panel position, interface language, whether the panel is minimized, and the repeat-counter toggle. These settings never leave your device.

4. Permissions

The Extension runs only on www.youtube.com pages and requests no other browser permissions.

5. Third parties

The Extension is not affiliated with YouTube or Google and shares no data with any third party.

6. Changes

If this policy changes, this page and the date above will be updated.
