Personal music synchronization utility
SongMirror is a private, non-commercial utility used by its owner to synchronize selected music-library information and playlists between Spotify and YouTube Music. It uses Google OAuth only after the account owner explicitly grants access.
SongMirror can read the owner's YouTube channel, playlists, playlist items, and liked-video state as needed for synchronization. When a synchronization is explicitly enabled, it can update the owner's YouTube music-library state and playlists.
SongMirror is not affiliated with or endorsed by Google, YouTube, Spotify, or their respective affiliates.
Google user data is used only to provide synchronization functionality requested by the account owner. It is not sold or used for advertising.
