2. Apple-Specific Terms

This Agreement is governed by the terms of the App Store Terms of Service ("App Store Terms") as defined by Apple Inc. You acknowledge and agree that:

2.1. Apple as Third-Party Beneficiary. Apple Inc. ("Apple") and its subsidiaries are third-party beneficiaries of this Agreement. Upon your acceptance of this Agreement, Apple will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.

2.2. Ownership of Apple-Branded Products. You acknowledge that this Agreement is concluded between you and Company only, and not with Apple. Apple is not responsible for the Application or its content. Apple has no obligation to furnish maintenance or support services for the Application.

2.3. Compliance with App Store Terms. You must comply with the App Store Terms of Service in your use of the Application. Apple may enforce such terms against you, and Company may enforce this Agreement against you.

2.4. Usage Rules. The Application is licensed, not sold, to you for use only under the terms of this Agreement. Apple's App Store Usage Rules apply to your use of the Application, including but not limited to rules regarding the number of devices on which the Application may be installed, family sharing, and re-downloading.

2.5. No Reverse Engineering. You may not, and may not permit others to, reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Application, except to the extent that such restriction is prohibited by applicable law.

2.6. Third-Party Terms. The Application may include or interact with third-party software or services. You must comply with the terms of service of such third parties.

3. Subscriptions, Billing, and Auto-Renewal

The Application offers auto-renewable subscriptions. Their prices are shown in the App Store and Google Play before you subscribe.

3.1. Auto-Renewal. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current subscription period. Your App Store or Google Play account will be charged for renewal within 24 hours prior to the end of the current period, and the cost of the renewal will be identified.

3.2. Managing Your Subscription. You can manage and cancel your subscriptions in your App Store or Google Play account settings on your device after purchase. Cancelling a subscription takes effect at the end of the current billing period — you will continue to have access to premium features until that date.

3.3. Free Trials and Promotional Offers. If Company offers a free trial or promotional subscription, any unused portion of the free trial period will be forfeited when you purchase a subscription to the same product.

3.4. Payment Processing. Purchases made within the Application are processed by Apple or Google through your App Store or Google Play account. For these purchases, Company does not collect, store, or process your payment information, and billing inquiries should be directed to Apple or Google. Purchases made on maestria.app are governed by Section 3A.

3.5. Refunds. Refunds of purchases made within the Application are handled by Apple or Google according to their refund policies. Company has no control over, and makes no representations regarding, their refund decisions. Refunds of purchases made on maestria.app are governed by Section 3A.

3.6. Price Changes. Company reserves the right to change subscription prices. Any price changes will take effect at the end of the current subscription period, and you will be notified in advance. If you do not agree to the new price, you must cancel your subscription before the renewal date.

3A. Purchases Made on maestria.app

Some offers are sold directly on https://www.maestria.app and paid through Stripe, not through Apple or Google. Sections 3.4 and 3.5 do not apply to these purchases; this section does.

3A.1. Lifetime Access. A single payment of $149.99 USD (plus VAT where Section 3A.7 applies), offered to two buyers only, until October 8, 2026 at midnight, Pacific Time. The offer closes earlier if the two places are taken or if Maestria opens to the public before then, and it is never extended. It gives access to Maestria's premium features, for the account registered with the email used at checkout, for as long as Maestria is operated, with no further payment: it does not renew. Access starts on the day Maestria opens to the public, announced for November 2026; we write to that email on opening day. If two payments for the last place are completed at the same time, both are honored. Section 3A.3 applies.

3A.2. Annual Subscription. $198 USD per year (plus VAT where Section 3A.7 applies), for access to Maestria's premium features for the account registered with the email used at checkout. The subscription starts on the day of payment, including when you subscribe before Maestria opens to the public. It renews automatically at the end of each year, at $198 USD per year (plus VAT where Section 3A.7 applies), charged to the payment method you used, until you cancel it as described in Section 3A.4. We send you a reminder email before each renewal. Section 3A.3 applies to a subscription taken before Maestria opens to the public.

3A.3. If Maestria Does Not Open. If Maestria is not open to the public by the end of November 30, 2026, Pacific Time, we refund in full every Lifetime Access payment and every Annual Subscription payment made before that date, to the payment method used and without you having to ask, and we cancel those subscriptions. You can also write to contact@maestria.app at any time.

3A.4. Cancelling Your Subscription. You can cancel your Annual Subscription at any time, through the customer portal linked from https://www.maestria.app/support with the email used at checkout or, if you bought it through Link (Section 3A.7), at link.com. Cancellation takes effect at the end of the year already paid: your access continues until then, and nothing is charged after it. Cancelling does not refund the year already paid, except as provided in Sections 3A.3, 3A.5 and 3A.8.

3A.5. Right of Withdrawal. If you are a consumer in the European Union or the United Kingdom, you may withdraw within 14 days of purchase and be refunded in full, by writing to contact@maestria.app.

3A.6. Payment Processing. Web purchases are processed by Stripe. Company does not store your card details.

3A.7. Purchases from the United Kingdom and the European Union. If you buy from the United Kingdom, a member state of the European Union, Monaco or the Isle of Man, the sale is made through Link: Sold through Link, LLC, which provides Stripe's merchant of record service (“Link”), sells the Lifetime Access or the Annual Subscription to you as merchant of record. VAT at your country's rate is added to the USD price, and the price shown to you, VAT included, is the price you pay; the final amount is shown in your currency at checkout. Link sends your receipts, handles payment support, manages your subscription at link.com, and applies its own payment terms and refund policy in addition to these Terms, which continue to govern your access to Maestria and the promise in Section 3A.3. At checkout, you confirm that you accept these Terms, including when your access starts (Sections 3A.1 and 3A.2).

3A.8. Automatic Refund Outside Link. If a payment is made through our standard checkout while both the card used and the billing address are in one of the countries listed in Section 3A.7, we refund it in full, automatically, cancel the subscription it started, if any, and invite you to pay through Link. Only these two items, read from Stripe, decide it; if either one is missing or outside those countries, the payment stands.

3B. Offers No Longer Sold

The following offers were sold on maestria.app before September 2026 and are no longer sold. Their terms continue to apply to the purchases made while they were offered.

3B.1. A Year of Maestria. A payment giving twelve months of access to Maestria's premium features, for the account registered with the email used at checkout, starting on the day of payment. It does not renew by itself. The same access is available as a subscription within the Application.

3B.2. The Piece of Your Life. A piano piece composed from the story you submit with the Maestria composition engine, which relies on third-party AI music services, and checked by ear before delivery. It is delivered within seven days of receiving your story (within seventy-two hours if you purchased the priority option), with a recording, a score, liner notes, a slow practice edition, a family edition, and a year of Maestria as described in 3B.1. The piece is not given to anyone else. It is licensed to you for personal, non-commercial use under Section 5.2; no copyright is transferred to you, and Company does not warrant that copyright subsists in AI-assisted compositions.

3B.3. Options offered at checkout, or once after payment. An option accepted on the page shown right after payment is charged, with your consent given by that click, to the payment method used for your order. The Bound Edition: a printed and bound copy of your score, shipped to the address given at checkout within four weeks of delivery of your piece; customs duties, if any, are yours. A Second Piece: a second piece composed from the story of a person you designate, delivered with its own editions under the same terms as 3B.2, without a second year of Maestria. Priority delivery: your piece is delivered within seventy-two hours of receiving your story; if we miss this deadline, the price of the priority option is refunded.

3B.4. The Sounds-Like-Me Promise. If you tell us within 14 days of delivery that your piece does not reflect your story, and what is missing, we rewrite it. You may ask for a second rewrite within 14 days of the new delivery. This promise gives up to two rewrites, not a refund, and you keep every version.

3B.5. The Eight Bars Promise. If, after practicing at least fifteen minutes a day for seven consecutive days, you cannot play the first eight bars of your piece, tell us within 30 days of delivery and we rewrite it one level easier. This promise gives a rewrite, not a refund.

3B.6. The Last Bar Recital. Offered by invitation after a call. Twelve weekly online lessons of 45 minutes with an independent piano teacher, weekly video feedback, a recital in a hall rented in or near your city for up to forty guests, hand-written invitations sent to the people you designate, a videographer and a photographer for the evening, a private recital page and a bound edition of your score. A deposit reserves the hall and the season; the balance is due before the first lesson. A lesson missed without 24 hours' notice counts as taken. The deposit is not refundable once the hall is booked; the balance is not refundable once the lessons have begun.

3B.7. The Last Bar Guarantee. If you attended all twelve lessons, sent a video of at least 60 seconds in each of the twelve weeks, practiced as agreed, and still cannot play your piece to the last bar by the end of week twelve, we move the recital to a later date and continue your weekly lessons at no cost until you can. This guarantee gives additional lessons and a new date, not a refund.

3B.8. The Heirloom Grand. Made to order. Each instrument is quoted individually with its maker. No payment is taken before you accept a written quote, whose terms then apply.

3B.9. Refunds and Right of Withdrawal. The promises above give rewrites, additional lessons or a new date, never a refund, because a piece written from one person's story cannot be resold. Except where the law of your country provides otherwise, payments are final once work on your order has begun. If you are a consumer in the European Union, you may withdraw within 14 days of purchase; by submitting your story and asking us to begin before that period ends, you acknowledge that you lose your right of withdrawal once your piece has been fully delivered.
