These Terms and Conditions ("Terms") govern your use of the Open Chord mobile application ("the App"), published by OAK TEK - FZCO ("we," "us," or "our"), a free zone company licensed by the Dubai Integrated Economic Zones Authority in Dubai, United Arab Emirates, under Trade Licence No. 90142.
By downloading, installing, or using the App, you agree to these Terms. If you do not agree, please do not use the App and remove it from your device.
Open Chord is intended for users aged 13 and older. If you are below the age of majority in your country, you may use the App only with the knowledge and agreement of a parent or legal guardian, who accepts these Terms on your behalf and is responsible for your use of the App.
The App requires no account, no registration, and no personal details of any kind.
Open Chord is offered only in selected countries. It is not offered in the European Economic Area, the United Kingdom, or Switzerland, and you should not use it there. If it is not offered in the country where you live, you should not download or use it.
You may not use the App if you are located in, or ordinarily resident in, a country or region that is subject to a comprehensive trade embargo, or if you appear on a government list of prohibited or restricted parties. You confirm that you are not in any of those positions. You must comply with the export control and sanctions laws that apply to you.
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own private, non-commercial learning.
This licence transfers no ownership. All rights not expressly granted here are reserved. Where we publish source code for the App under an open source licence, that licence governs the source code, and nothing in these Terms limits the rights it gives you.
Open Chord is a self-guided learning tool. It offers lessons, exercises, chord and scale references, a chromatic tuner, a metronome, practice tracking, and challenges.
It is not a substitute for a qualified guitar teacher, and we make no promise that using it will produce any particular level of skill, speed of progress, or result. Musical progress depends on your own practice.
Nothing in the App is medical, health, or professional advice of any kind, and it should not be relied on as such.
Playing guitar is a physical activity. Please take these points seriously:
You use the App at your own risk and are responsible for practising within your own physical limits.
You agree not to:
The App, including its design, layout, artwork, illustrations, icons, lesson text, exercises, challenge structure, original musical exercises, and the Open Chord name and logo, is owned by OAK TEK - FZCO and protected by copyright, trademark, and other intellectual property laws.
The riffs and songs taught in the App are, to the best of our knowledge, traditional, in the public domain, or original exercises written by us. We do not intend to reproduce, distribute, or teach copyrighted commercial recordings, lyrics, or sheet music. Whether a work is in the public domain can differ from country to country, and if you believe a work in the App infringes your rights, you can tell us as described below.
The App includes open source software, which remains the property of its respective authors and is used under its own licence terms. Nothing in these Terms limits your rights under those licences, and where an open source licence conflicts with these Terms, that licence prevails for the component it covers. A list of these components and their licences is available on our Open Source Licences page.
If you believe anything in the App infringes your intellectual property rights, please write to us at the address in section 19 with a description of the work, where it appears in the App, and your contact details. We will review and respond promptly.
Your progress, streaks, practice history, and preferences are stored only on your device. We do not hold a backup and cannot restore anything for you.
If you clear the App's data, use "Clear all data" inside the App, uninstall the App, reset your device, or lose your device, that information is gone permanently. You are responsible for keeping any record you wish to retain.
How we handle information is described in full in our Privacy Policy, which forms part of these Terms.
Open Chord is free. There are no subscriptions, no premium tiers, no paywalled lessons, and no in-app purchases.
The App is supported by advertising. Adverts are supplied by Google AdMob and appear as a banner at the bottom of the screen. To show adverts, Google collects information from your device, as described in our Privacy Policy, which also explains the choices you have about advertising.
We do not control, endorse, or take responsibility for the content of adverts, the products or services they promote, or any dealings you have with an advertiser. Any such dealing is strictly between you and the advertiser.
Most of the App works offline. An internet connection is needed the first time the App downloads its instrument sounds, which are served from a public content delivery network and then cached on your device. Analytics, crash reporting, and advertising also require a connection. You are responsible for any data charges from your mobile operator.
The App links out to our website and social media accounts. We are not responsible for the content or practices of any external site.
We may update, change, suspend, or discontinue the App or any of its features at any time. We do not promise the App will be available without interruption, or that it will be free of errors or defects.
Updates may be delivered through Google Play. Some updates may be required for the App to keep working.
The App is provided "as is" and "as available," without warranty of any kind, whether express, implied, or statutory. To the fullest extent permitted by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.
We do not warrant that the tuner will be accurate on every device or in every acoustic environment, that timing features such as the metronome will be free of drift, that the App will work on every device or Android version, or that any defect will be corrected.
To the fullest extent permitted by law, OAK TEK - FZCO will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, loss of progress, or loss of profits arising out of or connected with your use of the App, whether based in contract, tort, negligence, or any other legal theory, and whether or not we were advised of the possibility of such damages.
Subject to the next paragraph, and because the App is supplied free of charge, our total aggregate liability to you for all claims connected with the App is limited to one hundred United Arab Emirates dirhams (AED 100).
Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for our gross negligence, wilful misconduct, fraud, or fraudulent misrepresentation, or for any liability that cannot lawfully be excluded. Some jurisdictions do not allow the exclusion or limitation of certain warranties or liabilities, and where that is the case the exclusions and limitations above apply only to the extent permitted.
If you are a consumer, these Terms do not affect your statutory rights under the consumer protection law of your country of residence.
To the extent permitted by law, you agree to indemnify and hold harmless OAK TEK - FZCO and its officers and employees from any claim, demand, loss, or expense, including reasonable legal fees, arising out of your misuse of the App or your breach of these Terms. This section does not apply to your ordinary personal use of the App as a consumer.
You may end these Terms at any time by uninstalling the App.
We may suspend or terminate your licence to use the App if you materially breach these Terms. Sections 5, 6, 10, 11, 12, 16, and 17 survive termination.
The App is distributed through Google Play and the Apple App Store, and your use of each store is governed by its own terms. These Terms are between you and OAK TEK - FZCO only. Google and Apple are not parties to these Terms and have no responsibility for the App or for providing support for it. Any question, complaint, or claim about the App should be directed to us at the address in section 19, not to Google or Apple.
Google and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
If you download the App from the Apple App Store, the following also applies. In this section, "Apple" includes Apple Inc. and its subsidiaries.
We are not liable for any failure or delay in providing the App caused by circumstances beyond our reasonable control, including network or platform outages, failures of third-party service providers, acts of government, natural events, or industrial action.
These Terms are governed by the federal laws of the United Arab Emirates as applied in the Emirate of Dubai, without regard to conflict of law principles. The courts of Dubai have jurisdiction over any dispute arising from these Terms.
If you are a consumer, nothing in this section deprives you of any protection that the mandatory law of your country of residence gives you and that cannot be excluded by agreement.
We may assign or transfer these Terms, in whole or in part, to any successor in connection with a merger, acquisition, or sale of assets, provided your rights under these Terms are not reduced. You may not assign or transfer your rights under these Terms.
If any provision of these Terms is found unenforceable, the remaining provisions stay in full effect. Our failure to enforce any right is not a waiver of that right. Except for Google and Apple as described in section 14, no third party has any right to enforce these Terms. These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the App.
We may revise these Terms from time to time. When we do, we will update the "Effective Date" at the top of this page and add an entry to the change history below. Where a change is material, we will tell you in the App where practicable. Continued use of the App after that point constitutes acceptance of the revised Terms. If you do not accept a change, your remedy is to stop using the App and uninstall it.
