Terms of Service

Last updated: November 9, 2026

These terms govern your use of Chordseed, a web app operated by Miguel Ángel Núñez Gallo, Nevada, USA. By using Chordseed you agree to them.

Using Chordseed

You may use Chordseed for personal and professional music creation and learning. Don’t misuse the service: no attempts to break, overload or reverse-engineer it, and no use that breaks the law.

Your account

You are responsible for keeping your login secure and for activity on your account. Tell us right away if you think someone else is using it.

Your music is yours

Progressions, songs and exports you create with Chordseed belong to you. Chord progressions themselves are not owned by anyone, and you can use what you create in your own songs, commercially or not. You give us permission to store your content only so we can provide the service.

Chordseed Pro

Pro is a paid subscription, billed monthly or yearly through our reseller Paddle, which is the merchant of record for all orders and handles billing, taxes and refunds.
Subscriptions renew automatically until you cancel. You can cancel anytime; you keep Pro until the end of the period you paid for.
Refunds: if you are not happy, contact us within 14 days of your first payment for a full refund.
Prices may change; we will notify you before a change affects your next renewal.

Our content

The Chordseed app, name, logo, characters (including Lumen), design and lessons are owned by us and may not be copied without permission. Instrument sounds are based on FluidR3 GM by Frank Wen (CC BY 3.0).

No warranty

Chordseed is provided “as is”. We work hard to keep it accurate and available, but we can’t guarantee it will always be error-free or uninterrupted. To the extent the law allows, we are not liable for indirect or consequential damages, and our total liability is limited to the amount you paid us in the last 12 months.

Ending use

You can stop using Chordseed and delete your account anytime. We may suspend accounts that break these terms.

Law

These terms are governed by the laws of the State of Nevada, USA.
