Terms of Use

Ear Training: Music Theory Lab · Last updated November 9, 2026

These Terms of Use (“Terms”) are an agreement between you and AppGrowth ATX LLC (“we,” “us,” “our”), a Texas limited liability company, for your use of Ear Training: Music Theory Lab (“the app”). By downloading or using the app, you agree to these Terms. If you do not agree, do not use the app.

These Terms work together with Apple’s Licensed Application End User License Agreement (the “Apple EULA”). If they conflict, these Terms apply to the extent permitted by the Apple EULA.

1. The app

The app provides ear training and music theory lessons, drills, games and tools. We grant you a personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, for your own non-commercial use, in line with these Terms and the Apple EULA.

2. Subscriptions

3. Acceptable use

You agree not to copy, modify, distribute, sell or lease any part of the app; reverse engineer it or try to extract its source code, except where the law allows; get around its subscription or security features; or use it in any way that breaks the law.

4. Ownership

The app, including its lessons, design, artwork, mascot and code, belongs to AppGrowth ATX LLC and is protected by intellectual property laws. The piano sound is the Accurate-Salamander Grand Piano, used under the CC BY 3.0 license and credited in the app.

5. Educational purpose

The app is for practice and learning. Results depend on your own practice, and we do not promise any particular outcome, such as developing perfect pitch, passing an exam or reaching a certain level within a certain time.

6. Privacy

Our Privacy Policy explains what information the app handles. In short, your progress stays on your device and microphone audio is never recorded or sent anywhere.

7. Disclaimers

The app is provided “as is” and “as available.” To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not guarantee that the app will be error-free or available without interruption.

8. Limitation of liability

To the fullest extent permitted by law, AppGrowth ATX LLC will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, arising from your use of the app. Our total liability for any claim relating to the app will not exceed the amount you paid for the app in the twelve months before the claim. Some places do not allow these limits, so they may not apply to you.

9. Apple

These Terms are between you and AppGrowth ATX LLC, not Apple. Apple is not responsible for the app or its content, has no obligation to provide maintenance or support for it, and is not responsible for any claims relating to it. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

10. Changes and termination

We may update the app and these Terms. If we change the Terms, we will update the date above; continuing to use the app after a change means you accept the new Terms. We may suspend or end your access if you break these Terms. You may stop using the app at any time by deleting it and cancelling your subscription.

11. Governing law

These Terms are governed by the laws of the State of Texas, United States, without regard to its conflict of law rules. Any dispute will be resolved in the state or federal courts located in Travis County, Texas, unless the law where you live gives you the right to bring a claim in your local courts.
