Who We Are

Cat-alogue ("the App", "we", "us", "our") is a lyrics and sheet-music management application developed and maintained by an independent developer. The app is built to help musicians, worship leaders, and performers store their repertoire, build setlists, and perform with confidence — on Android, iOS, Windows, and macOS.

The developer acts as the data controller for personal data processed through this app and website. For any privacy-related enquiries contact us at [email protected].
