Terms of Service

Rock Guitar Power is a trading name of Medurik Corporation, 20 Dewberry Drive, Rochester, NY 14622, USA. “We”, “us” and “our” mean Medurik Corporation. “You” means the person using the site.

These terms cover the public website at rockguitarpower.com, the members site at lessons.rockguitarpower.com, our emails, the free skill quiz, and the AI guitar assistant. You agree to these terms and to our Privacy Policy when you create your password (the acceptance line is shown right there), start a trial, buy a membership, or use the site. If you do not agree, please do not use the site.

• You must be at least 13 years old to use the site. If you are under 18, a parent or guardian must agree to these terms for you and must be the one who pays.
• One person per account. Sharing your login, or letting several people learn from one account, is not allowed and can end your membership without a refund.
• Keep your password private and tell us right away at support@rockguitarpower.com if you think someone else is using your account.
• Give us accurate details (a real name and a working email address).

We add, update, and occasionally retire lessons as the site develops.

• The monthly membership starts with a 7-day free trial. A payment card is required to start it, but nothing is charged during the trial.
• When the 7 days end, your card is charged $9.95 and then $9.95 every month after that, unless you cancel before the trial ends. We email you a reminder about 3 days before the first charge.
• You can cancel during the trial from Manage Billing in your account settings. If you cancel, you keep access until the trial ends and you are never charged.
• One free trial per person. If you had a trial before and come back, your membership starts with a payment.

• Automatic renewal. Monthly and yearly memberships renew automatically at the end of each billing period, at your locked price, until you cancel.
• Yearly reminder. We email yearly members about 7 days before each renewal.
• Switching plans. You can switch between monthly and yearly in Manage Billing. The difference is pro-rated, so you only pay for what you use.
• Payment method. Memberships are paid by card (including Apple Pay and Google Pay) through Stripe. Your card details go directly to Stripe; we never see or store them.
• Failed payments. If a renewal payment fails, you will be asked to update your card. If it still cannot be collected after a few tries, your membership ends and your access stops.
• Receipts. We email a receipt when your membership starts, and your billing history is in Manage Billing.

You can cancel at any time, online, with no fee and no need to contact us or explain: use Manage Billing in your account settings (or email support@rockguitarpower.com if you prefer). Nothing more is charged and you keep full access until the end of the period you have already paid for (or the end of your free trial). We send a confirmation email with your access-end date.

Outside the 60-day guarantee below, payments already made are not refunded when you cancel, and unused time is not refunded in part.

• The 60 days start with your first payment (the free trial does not count). On the monthly plan this can be two monthly payments, and both are refunded. Your access ends when the refund is issued.
• After 60 days: you can still cancel at any time (section 6), but payments already made are not refunded.
• Refunds go back to the original payment method and normally appear within 5 to 10 business days, depending on your bank.
• We may decline the guarantee only for someone who has already received a refund and rejoins to repeat it.

When you take our skill quiz and give us your email address, we give you free access to the course that matches your level. That access is a gift for your own use. It can be changed or withdrawn, it does not include the other courses, and because nothing was paid, no refund applies.

If you break these rules we may suspend or end your account without a refund.

Everything on the site, including the videos, tabs, chord charts, backing tracks, written lessons, blog posts, images, the Rock Guitar Power name and logo, and the site itself, belongs to Medurik Corporation or is used with permission, and is protected by copyright and trademark law. A membership gives you permission to use the materials as described in section 9; it does not transfer ownership of anything to you.

If you send us feedback or a support message, we may use it to improve the site. We publish a testimonial only with your permission, and then with your first name only.

• The public assistant on the website answers up to 10 questions per visitor per day. Members can ask questions inside every lesson.
• Answers are written by an AI model (currently from OpenAI) using your question and the relevant lesson text. We do not keep your questions or the answers.
• AI answers can be incomplete or wrong. Use them as a study aid, not as a substitute for the lessons or for advice from a qualified teacher or doctor.
• Please do not type personal, financial, or medical information into the assistant. We may limit or switch off the assistant at any time.

We always send account emails such as receipts, trial and renewal reminders, cancellation confirmations, and password resets; these are part of the service. Lesson tips, follow-ups, and offers are optional, and every one has an unsubscribe link. Details are in our Privacy Policy.

We work hard to keep the site available, but no online service is perfect. There may be short outages, and video playback depends on your own connection and device. We may change, add to, or remove features as the site develops.

If the business is sold, your membership and access continue with the new owner. If we ever close the site, we will give active members notice and refund the unused part of any yearly membership.

Everyone learns at a different pace. We cannot promise a particular level of playing by a particular date. The lessons are provided “as is”; we do not promise they are error-free or suit your particular needs. Guitar is a physical activity: warm up, take breaks, and stop if something hurts. Nothing on the site is medical advice.

To the fullest extent the law allows, Medurik Corporation is not liable for indirect or consequential losses (for example lost profits, lost data, or equipment damage) arising from your use of the site, and our total liability to you for any claim is limited to the amount you paid us in the 12 months before the claim arose. Nothing in these terms limits liability that cannot be limited by law, or the consumer rights you have where you live.

We may update these terms from time to time. Small clarifications take effect when we post them. For changes that affect your rights or what you pay, we email members and post a notice on the site at least 14 days before the change applies. Continuing to use the site after that date means you accept the new terms; if you do not, cancel before then and section 6 applies. Earlier versions are available on request.

These terms are effective October 10, 2026 and were last updated October 10, 2026. They replace all earlier versions.
