One email for everything
Clef is built and supported by one person. Whether it's a support question, a bug, feedback, or a press inquiry, write to [email protected] — your message lands directly with the founder, not a ticket queue. You'll usually hear back within one to two business days.
Reporting a bug
The more of this you can include, the faster it gets fixed:
- Your browser and version (for example, Chrome 126).
- Your keyboard or digital piano model and how it's connected.
- The piece you were practicing and what you were doing when it happened.
- What you expected, and what happened instead.
