Is AudD® Music Recognition safe?
AudD Music Recognition sends tab URL, page title, and a persistent device ID to api.audd.io on every song recognition request.
When a user initiates a song recognition, the extension collects the current tab URL, page title, and browser UI language, and transmits them to api.audd.io alongside the audio sample. A pseudonymous device ID generated on first install is also included in every request, enabling the API provider to correlate a user's recognition history across sessions. Free-tier requests additionally include an RC4-obfuscated hidden form field whose purpose is unclear.
