Terms of use
Good Ears is a personal practice tool, offered free and without warranty. These terms are short because the app asks little of you.
What you can expect
- The app is provided as is. It is a hobby project that may change, break, or go offline without notice. Do not rely on it as the only record of your practice.
- Grading is an honest best effort by a computer listening through a microphone. It is not a teacher, and it can be wrong — particularly with background noise, chords, or an instrument it was not designed for.
- The source code is open under the GPL-3.0-or-later licence. You are welcome to read it, run your own copy, and see exactly what it does.
What is asked of you
- Only upload music you have the right to use. The library exists so you can practice from books you own. Sheet music is usually copyrighted; photographing your own copy for your own practice is one thing, and redistributing it is another. Pages you add stay on your device, so this is a matter of your own use, not something the app polices.
- Do not attempt to disrupt the service or use it to store or transmit anything unlawful.
- Accounts are for people. Please do not automate sign-ups.
Liability
To the extent the law allows, the author is not liable for any loss arising from use of this app — including lost practice history, an incorrect grade, or the service becoming unavailable.
Ending things
You can stop using Good Ears at any time; clearing your browser data removes what is stored locally. Ask and any account and its practice history will be deleted.
