Lyric Timer does not collect, store, or transmit any personal data.

The only network requests the extension makes are search queries and
lyric lookups sent to the public LRCLIB API (https://lrclib.net). A
request contains nothing but the song title/artist you type into the
search field. No account is required, and there is no tracking, no
analytics, and no advertising.

All extension data — playlists, favorites, playback history, settings,
and session state — is stored locally in your browser and never leaves
your device. Optional playlist export encryption happens entirely on
your device; passwords are never transmitted anywhere.
