These Terms of Use govern your use of Keytionary ("the App"), developed by Renmus Software LLC ("we", "us", "our"). By downloading or using the App, you agree to these terms.

Disclaimer

The App is provided "as is" without warranties of any kind. We are not responsible for any errors in the music theory content or interruptions in service.
