Unfortunately there is no feature for recording and saving your performances for copyright reasons in Singa. You are allowed to use Singa as background music and record your performance with another device though.

If you like to share videos from your performances to social media that can be done, but make sure the lyrics of the songs are not visible on the video. It is advisable to look into the terms and regulations of the platform you're using before posting content including music or other copyrighted content.
