Terms of Service

Effective: November 12, 2026 · Sea Ridge Strategy Group LLC

1. Who we are

Accordion From Zero (also presented as Acordeón From Zero) is an online, self-guided music education service operated by Sea Ridge Strategy Group LLC, a limited liability company organized in Wyoming, United States ("we", "us"). These Terms are an agreement between you and us. By creating an account, starting a membership or using the site, you agree to them.

2. Who can use the service

You must be at least 13 years old to create an account. If you are under 18 (or the age of majority where you live), a parent or legal guardian must agree to these Terms for you and is responsible for any membership purchase. We do not knowingly collect personal information from children under 13.

Keep your password private and tell us right away if you think someone else has used your account. You are responsible for activity under your account.

3. Free lessons

The first lesson of every published course is free, with no account or payment needed. We may change which lessons are free, but we will not take away access you have already paid for.

4. Memberships, billing and automatic renewal

A membership gives you access to every published lesson and the practice tools for as long as it is active. We offer monthly and annual plans; the current prices are shown on the Pricing page and at checkout before you pay.

Your membership renews automatically at the end of each billing period (every month or every year) at the then-current price, plus any applicable tax, and your payment method is charged on the renewal date until you cancel. Payments are processed by Stripe; we never see or store your full card number.

If we change the price of your plan, we will tell you by email at least 30 days before the new price applies, and you can cancel before it does. If a renewal payment fails, Stripe will retry it for a short time; access may be paused if payment is not completed.

Full details are in our Subscription Terms, which are part of these Terms.

5. Cancelling and refunds

You can cancel anytime, online, from your Account page. Cancellation stops future renewals; you keep access until the end of the period you already paid for. We do not provide refunds or credits for partial periods, except where the law requires it or we decide otherwise in a specific case.

If you live in a country whose consumer law gives you additional rights (for example, a right to withdraw from a purchase within a set number of days), those rights apply. Because lessons are available immediately, where the law allows, starting a membership means you ask for access to begin right away.

6. What the lessons are, and what they are not

Lessons are written instruction, interactive diagrams, synthesized sound and automatic exercise checks. There are no live classes or teachers. Exercises check your answers on screen; they cannot hear your instrument, so on-screen progress is not proof that you played something correctly. Everyone learns at a different pace and we do not guarantee any particular result or timeline.

Play safely: take breaks, stop if you feel pain, and handle the instrument and bellows carefully. Button layouts follow published manufacturer charts for the G/C/F accordion; instruments vary, so check yours.

7. Your licence and acceptable use

We give you a personal, non-transferable, non-exclusive licence to use the lessons for your own learning. Don’t share your account, resell or redistribute lesson content, copy the site or its content in bulk, try to get around access controls, interfere with the service, or use it unlawfully.

8. Intellectual property

The site, lessons, original melodies, text, diagrams and software belong to us or our licensors and are protected by law. Musical facts such as tunings and scales are common knowledge; our presentation of them is ours. Fonts are used under the SIL Open Font License.

9. Changes and availability

We regularly add and improve lessons and may change or retire features. We try to keep the service available but don’t promise it will always be uninterrupted or error-free.

10. Disclaimers and limitation of liability

To the extent the law allows, the service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose.

To the extent the law allows, we are not liable for indirect, incidental, special or consequential damages, and our total liability for any claim relating to the service is limited to the amount you paid us in the 12 months before the claim. Nothing in these Terms limits liability that cannot be limited by law, or your statutory consumer rights.

11. Ending your account

You can delete your account at any time from your Account page; this cancels any membership immediately with no further charges. We may suspend or close accounts that break these Terms, after notice where reasonable.

12. Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, USA, without regard to conflict-of-law rules. If you are a consumer, you also keep the protection of mandatory laws of the country where you live, and you may bring claims in your local courts where the law allows. Please contact us first so we can try to resolve any issue informally.

13. Changes to these Terms

We may update these Terms. We will post the new version here with a new effective date and, for material changes affecting members, email you in advance. Continuing to use the service after changes take effect means you accept them.
