Clef terms of service

We grant you a personal, non-exclusive, non-transferable, revocable license to use Clef for iOS and the web trainer for your own practice

The web trainer at clefdrills.com is free to use, needs no account, and is for personal, non-commercial sight-reading practice.

You may not resell access, embed the trainer in another product, systematically scrape or bulk-download its content

Don't attempt to reverse-engineer, decompile, or extract the underlying drill logic, note-scheduling algorithm, or staff-rendering code

Don't attempt to unlock paid features without a valid purchase or subscription

Don't use the service in any way that violates applicable law, infringes someone else's rights, or attempts to disrupt or overload the app, the site, or its infrastructure.

You're licensed to use the service, not to copy its design or code elsewhere.

To the fullest extent permitted by law, Clef's operator isn't liable for any indirect, incidental, special, or consequential damages arising from your use of, or inability to use, the service

This license ends automatically if you violate these terms.

Material changes will update the "last updated" date above. Continued use of Clef after a change means you accept the updated terms.
