Terms of use
Short, because the service is short: you drop a file, your own browser analyses it, and we never see it.
The service
EarChord on the web is a free tool that estimates the chords, key and tempo of audio you supply. It runs in your browser. There is no account, no payment and no stored data on the website or in the Chrome extension, so there is nothing to subscribe to and nothing to cancel on either of them. The iPhone app has a paid tier, and it has its own section below.
Accuracy
The results are estimates produced by signal processing, not a transcription by a musician. They are frequently right and sometimes wrong, particularly on dense or distorted material, and the chord vocabulary is limited to major and minor triads by design. Use them as a starting point and trust your ears over the timeline. EarChord is provided as is, with no warranty of accuracy or fitness for any particular purpose.
The audio you analyse
You are responsible for having the right to analyse whatever you put into the tool. Because the file never leaves your device we cannot see, store, copy or distribute it, and the tool does not download or reproduce anyone's recording. Analysing music you own or have legal access to, in order to learn to play it, is the use this is built for.
The Chrome extension
The extension reads audio a video is already playing in your own browser in order to display chords. It does not download video or audio, does not defeat any access control, and stores nothing beyond your own preferences. Use it in line with the terms of whatever site you are using it on.
The iPhone app
EarChord for iPhone is a different product on the same brand: it is an ear training app, and it does not analyse recordings at all. The whole intervals track is free with no account and no time limit. EarChord Pro is an auto-renewing subscription that adds the chords, scales and progressions tracks.
The subscription is sold and billed by Apple, not by us. It is governed by Apple's standard licence agreement, theLicensed Application End User License Agreement, which is what applies to your use of the app itself. Payment is charged to your Apple Account at confirmation of purchase, a subscription renews automatically at the same price unless it is cancelled at least 24 hours before the current period ends, and you manage or cancel it in your Apple Account settings. We never see your name, your email address or any payment detail; refunds are Apple's to give.
Liability
To the extent permitted by law, EarChord is not liable for any loss arising from use of the site, the extension or the app, including reliance on a chord it got wrong. The website and the extension are free and hold none of your data; the app's own licence terms are Apple's, linked above.
Availability
The site is provided without any uptime guarantee, and features may change or be withdrawn. Anything that would change how your data is handled goes on theprivacy page first.
