Lyricron
Privacy

Your files stay on your device

Lyricron is built around one idea: a lyrics tool shouldn't need your song files. Nothing you load is uploaded, and nothing about you is tracked.

The short version

  • Nothing is uploaded. Your audio, lyrics, and timestamps never leave your device.
  • No analytics. There is no tracking, no cookies, and no third-party scripts watching you.
  • Local-only storage. Your project auto-saves in your browser, not on a server.
  • No account. There's nothing to sign up for, so there's nothing to link back to you.

How it works

Lyricron is a static web app with no backend. When you load a song, the browser decodes the audio locally using the Web Audio API and plays it back in memory. The lyrics you type, the timestamps you create, and the file you export are all generated on your machine.

The fonts are bundled so the page doesn't even need to reach a font CDN after it loads. The only network requests Lyricron makes are the ones you start yourself, such as an optional LRCLIB search to look up lyrics for a track.

A note on decoding. If your browser cannot decode a particular audio format natively, Lyricron falls back to the browser's built-in media player for that file. The fallback still uses a local object URL, so the file is never uploaded. Timing may be less precise on variable-bitrate files in this mode.

Where your project lives

Your current project auto-saves to your browser's local storage so a refresh doesn't lose your work. Because there's no server, clearing your browser data clears your project, and nothing lingers anywhere else.
