Privacy

SimpMusic doesn't have any tracker or third-party server for collecting user data in FOSS version. If YouTube
logged-in users enable "Send back to Google" feature, SimpMusic only uses YouTube Music Tracking API to send listening history and listening record of video to Google for better recommendations and
supporting artist or YouTube Creator (For API reference,
see this).

We collect crash data in the Full version to improve the app.

Full or FOSS version

I use Sentry crashlytics to catch all crashes in the Full version. Sentry is the open-source project. If you don't want to be collected crash data, you must use FOSS version.

FAQ

1. Wrong Lyrics?

Lyrics are provided by LRCLIB and other sources. Sometimes lyrics may not match perfectly with YouTube"
videoId" parameter. So I need to use some "String Matcher" and "Duration" for search lyrics. So
sometimes, some songs or videos get the wrong lyrics

2. Why the name or brand is "SimpMusic"?

Simply, because I love the name. It's a combination of 'Simple' and 'Music'. But SimpMusic is not a simple app, it's all you need for a powerful music streaming app.
