Effective Date: October 18, 2026
These Terms of Service ("Terms") govern your use of Guitar Visualizer ("the App"), developed and operated by Juan Negron ("we", "us", or "our"). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
If you are under the age of majority where you live, you may use the App only with the permission of a parent or legal guardian, who agrees to these Terms on your behalf.
Guitar Visualizer is a guitar learning and fretboard visualization tool for personal, non-commercial use. You may use it to explore scales, chords, voicings, modes, and other music theory concepts.
You agree not to:
Guitar Visualizer offers optional auto-renewable subscriptions (for example, monthly and yearly plans) that unlock all features of the App. Purchases are made through the Apple App Store or Google Play, depending on your device.
The price, billing period, and any free trial are shown in the App before you subscribe, in your local currency. Prices can differ by country and can change over time. A price change for new subscribers does not change the price of a subscription you already have unless the App Store or Google Play informs you in advance, as their rules require, and you have the chance to cancel before it applies.
When a free trial is offered, you are not charged during the trial. Unless you cancel at least 24 hours before the trial ends, the subscription starts and you are charged at the end of the trial. The App Store and Google Play decide who is eligible for a trial (usually one per account).
On iPhone or iPad: Settings > [your name] > Subscriptions. On Android: Google Play > Profile > Payments & subscriptions > Subscriptions. You can also open these from the App's Settings. Canceling stops the next renewal; you keep access until the end of the period you already paid for. Deleting the App does not cancel a subscription.
All payments are processed by Apple or Google, not by us, and their refund policies apply. Apple: reportaproblem.apple.com. Google Play: support.google.com/googleplay/answer/2479637.
Some features may be available without a subscription. We may change which features are free at any time.
The App is a tool to help you learn and practice. How much you learn depends on you: your practice, your effort, and your starting point. We do not promise any particular result, such as playing better, faster, or by a certain date.
What we and others show about the App, in the app stores, on our website, in ads, and in videos and posts on social media (for example TikTok, Instagram, or YouTube), including content by creators we work with, is illustrative. It shows how the App can be used. Individual results vary, and that content is not a promise or a guarantee.
Features that listen to your instrument (note recognition) work by estimating sound and may not detect every note correctly, especially with background noise, an untuned instrument, or a poor microphone.
All content, design, code, graphics, and other materials in the App are owned by Juan Negron and protected by copyright and other intellectual property laws. You may not reproduce, distribute, or create derivative works from any part of the App without our prior written permission. Your use of the App gives you a personal, limited, non-transferable, revocable license to use it under these Terms; it does not transfer any ownership to you.
To the fullest extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.
We do not guarantee that the App will be error-free, uninterrupted, or free of bugs, or that its content is complete or correct. Music theory content is provided for educational purposes and is not professional music instruction.
To the fullest extent permitted by law, Juan Negron will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, use, or goodwill, arising from or related to:
To the fullest extent permitted by law, our total liability for all claims relating to the App or these Terms is limited to the amount you paid for the App in the 12 months before the event that gave rise to the claim, or US$10 if you paid nothing.
Some countries, states, and provinces do not allow certain warranties to be excluded or certain liability to be limited. In those places, the exclusions and limits above apply only as far as the law allows. Nothing in these Terms takes away rights you have under consumer protection laws that cannot be waived by contract.
You agree to hold us harmless from claims, losses, and costs (including reasonable legal fees) brought by third parties that arise from your misuse of the App or your breach of these Terms.
We may modify, update, or discontinue the App or any of its features at any time. To the fullest extent permitted by law, we are not liable to you or any third party for any modification, suspension, or discontinuation of the App.
We may suspend or end your access to the App if you violate these Terms or use the App in a way that harms other users, us, or third parties. You can stop using the App at any time; to stop being charged, cancel your subscription as described in section 2.
If you have a problem with the App, please contact us first at hello@guitarvisualizerapp.com. Most issues can be solved quickly this way. You agree to try to resolve any dispute informally for at least 30 days before starting a formal claim.
These Terms are governed by the laws of the State of Florida, USA, without regard to its conflict of law rules. Any claim that is not resolved informally will be brought only in the state or federal courts located in Florida, except that either party may bring an individual claim in small claims court. To the fullest extent permitted by law, claims may be brought only individually, not as a plaintiff or class member in any class or representative action. If you live outside the United States, this section does not deprive you of the protection of mandatory laws of the country where you live.
If you downloaded the App from the Apple App Store, you and we acknowledge that:
If you downloaded the App from Google Play, Google's terms for Google Play also apply to your purchase.
We may update these Terms from time to time. The updated version will be posted on this page with a new effective date. If a change is significant, we will also make reasonable efforts to tell you, for example in the App. Your continued use of the App after changes take effect means you accept the updated Terms.
If any part of these Terms is found unenforceable, the rest stays in effect. If we do not enforce a right, that is not a waiver of it. These Terms are the entire agreement between you and us about the App.
