Is PlayXylo safe?

This extension provides a digital xylophone with real xylophone sounds and touch, mouse, and keyboard controls.

PlayXylo opens to a colorful xylophone board for playing notes by tapping, clicking, sliding, or pressing corresponding number keys. It includes options such as rainbow and Boomwhacker colors, Solfege labels, a chromatic scale, dark mode that follows the system theme, and layout and language adaptation based on the system. The description says the app also works offline and includes a community section with videos accessible from the navigation menu.
