About Librezam

This extension is a browser extension that recognizes music currently playing in the current tab using Shazam's internal API and multiple alternative backends. No telemetry or other communications unrelated to music recognition are performed. To learn about the characteristics of each backend and how user data is processed, please see the Privacy Policy section. This is an unofficial project and has not received any assistance from Apple Inc. or the providers of alternative backends. Source code https://github.com/FoxRefire/Librezam
