Terms of Service

Rock Guitar Power is a trading name of Medurik Corporation. “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. By creating an account, starting a trial, buying anything, or simply using the site, you agree to these terms and to our Privacy Policy. 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. Your login is for you only. Sharing it with other people, 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 use your email for receipts, account notices, and, if you agree, lessons and tips.

• 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 the price you joined at, until you cancel.
• Yearly reminder. We email yearly members about 7 days before each renewal, so there are no surprise charges.
• 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 methods. Memberships are billed by card (including Apple Pay and Google Pay) through Stripe. The Lifetime option can also be bought with PayPal. Your card details go directly to Stripe or PayPal; we never see or store your full card number.
• Failed payments. If a renewal payment fails, Stripe emails you so you can 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 for every payment. Your payment history is also in Manage Billing.

You can cancel at any time, with no fee and no need to explain, from Manage Billing in your account settings, or by emailing support@rockguitarpower.com. When you cancel, nothing more is charged and you keep full access until the end of the period you have already paid for (or until 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.

• Monthly and yearly memberships: ask within 60 days of your first payment (the free trial does not count) and we refund every membership payment you have made. Your access ends as soon as the refund is issued.
• Lifetime: ask within 60 days of your purchase and we refund the full amount. Your access ends when the refund is issued.
• Upgrading to Lifetime while on a membership: we cancel your membership right away and refund your most recent membership payment.
• 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.
• The guarantee is for genuine customers. We may decline a refund to someone who repeatedly joins, consumes the courses, and asks for their money back, or who has broken these terms.

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 later start an All Access membership, the free course is simply part of it.

If you break these rules we may suspend or end your account without a refund, and we may take further action where the law allows.

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. Buying 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, a testimonial, or a support message, you let us use it to improve the site and, for testimonials, to show on the site with your first name unless you tell us not to.

• The public assistant on the website answers up to 10 questions per visitor per day. Members can ask as many questions as they like inside every lesson.
• Answers are generated by an artificial-intelligence model from our lesson transcripts and blog posts. To do this we send your question, and the relevant lesson text, to a third-party AI provider (currently OpenAI). Your question is not used to identify you.
• AI answers can be incomplete or simply 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 keep questions and answers to improve the assistant and to stop abuse, and 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: every one of those emails has an unsubscribe link and a link to your email preferences. Details are in our Privacy Policy.

We work hard to keep the site available around the clock, but no online service is perfect. There may be short outages for maintenance or problems outside our control, and video playback depends on your own internet connection and device. We may change, add to, or remove features and content as the site develops.

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 make any warranty that 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, and nothing limits the consumer rights you have in the place 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 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.

These terms are effective October 3, 2026 and were last updated October 3, 2026. They replace all earlier versions.
