Terms of Use
Last updated: 14 October 2026
1. Who we are
VERMUS is a music education platform presenting the improvisation method "Como Eu Penso" ("How I Think"), by Thiago Espirito Santo, operated under the Espírito Santo Music brand by ESPIRITO SANTO MUSIC PRODUÇÃO E COMÉRCIO LTDA-ME, registered under Brazilian company number (CNPJ) 33.179.602/0001-07 ("we", "the platform" or "VERMUS").
By creating an account or subscribing to any plan, you declare that you have read, understood and agree to these Terms of Use and to the Privacy Policy.
2. What the platform offers
The platform, available at vermus.com.br, shows, for each chord of a song, the scales, triads and arpeggios that apply under the "Como Eu Penso" method by Thiago Espirito Santo, including the reading chosen by its creator and the remaining harmonic possibilities. It offers a library of songs already analysed, expanded periodically, allows you to upload chord charts by photo or file for analysis, and to hear and see the result. VERMUS is an educational tool: it does not guarantee artistic results, approval, performance or any specific objective, which depend on each user's study and practice.
Automatic reading of chord charts uploaded as a photo or file is limited to 30 readings per month per subscriber, renewed on the 1st of each month. The library, typing in chord charts and the other features have no usage limit.
A sample song, with its full analysis, is open to any visitor so that you can get to know the platform before subscribing. It is protected like all the platform's content (clauses 9 and 11), and making it open does not assign any right.
3. Who may use it
The platform is open to students of any age — music can be studied at any stage of life. However, as this is a paid contract with automatic renewal, the subscription must be taken out by a person over 18. Persons under 18 may use the platform provided that the subscription is taken out and the payments authorised by a parent or legal guardian, who also consents to the processing of the minor's data.
4. Registration and account
To use the platform you create an account and provide true, complete and up-to-date information: name, e-mail, tax ID (CPF or CNPJ), telephone and instrument. When subscribing to a plan you also provide the billing address, required by our payment processor. Subscribers outside Brazil do not provide a Brazilian tax ID or a billing address. You are responsible for keeping your password confidential and for all activity on your account. The account is personal and non-transferable.
5. Plans, payment and renewal
The platform is offered by subscription, under the plans and prices shown on the plans page at the time of purchase. Currently:
Monthly — charged month by month;
Founder — annual plan at a promotional price, available for a limited time, with a locked-price guarantee (see clause 6);
Annual — 12-month plan.
Processing. Payments are processed by Asaas (Asaas Gestão Financeira Instituição de Pagamento S.A.). We do not have access to your card details, nor do we store them.
Card payment. Payment is made by credit card, with automatic renewal: at the end of each cycle — monthly or annual, depending on the plan — the charge is made automatically to the registered card, at the plan's current price, until you cancel. You authorise this recurring charge when subscribing. Any price adjustments will be communicated in advance. Cards issued outside Brazil are accepted. For subscribers outside Brazil, the price is advertised in US dollars and the charge is made in Brazilian reais, converted by the card issuer at the day's exchange rate; the amount in reais is shown before you subscribe.
7-day free trial. Anyone who has never been a subscriber may start with 7 (seven) free days on the Monthly, Founder and Annual plans paid by credit card, by registering a card. During the trial, access is full and nothing is charged. The trial is granted once per account and does not exist for payment by Pix. We may refuse the trial in case of misuse or an attempt to obtain more than one.
Charge at the end of the trial. If you do not cancel before the trial ends, the first charge for the chosen plan is made automatically to the registered card, on the eighth day, on the date and for the amount shown before you registered, and the subscription then renews automatically, as described in "Card payment". We e-mail you when the trial starts, two days before the charge, and after it.
Pix payment. All plans, monthly and annual, may also be paid by Pix, at the price shown on the plans page, which may differ from the card price. Pix has no free trial. A Pix subscription is recurring: at each cycle we automatically generate a new charge and send it to you by e-mail in advance. If your bank offers Pix Automático and you authorise the renewal at the time of the first payment, the following cycles are debited automatically, with no action from you. Otherwise, each renewal depends on your payment. Pix requires a Brazilian tax ID (CPF or CNPJ) and is available only to payers in Brazil.
Access, release and interruption. Access is released automatically as soon as payment is confirmed — or, in the free trial, as soon as the card is accepted — normally within a few minutes. If a charge falls due unpaid, access continues during a grace period of 8 (eight) calendar days from the due date, and is interrupted at the end of that period. This period covers the automatic retry attempts made by the payment processor. On the first charge after the free trial, if the card is declined, access is interrupted within 1 (one) calendar day after the trial ends. Once the outstanding amount is paid, access is restored automatically.
6. Founder plan price guarantee ("locked price")
Sale in batches. The Founder offer is sold in three batches, with an increasing price at each batch. The price in force at the time of purchase — that of the open batch and of the payment method chosen — is locked forever for that subscriber, under the terms of this clause, and is recorded in their subscription. On plans with a free trial, the time of purchase is the time the card is registered: the price, the batch and the validity of the offer are those of that day, even if the first charge takes place after a change of batch or after the offer has ended. The offer ends when the places run out; whoever has registered their card by then keeps the Founder price at the first charge. After that, the annual plan price then in force applies.
The Founder plan gives the subscriber a lifetime price guarantee: the annual amount contracted as a Founder remains the same at every renewal, without adjustment, for as long as the subscription is kept active and uninterrupted. This guarantee is an obligation of the company towards the Founder subscriber, and not a mere promotional statement. Each payment method has its own locked amount: whoever subscribes by card keeps the card amount; whoever subscribes by Pix keeps the Pix amount.
The guarantee ceases to apply if the subscription is cancelled by the subscriber, including during the free trial, or interrupted for non-payment. In that case, a new subscription will be subject to the plans and prices in force on the date of the new purchase, which may no longer include the Founder condition.
Renewal by Pix. A subscription paid by Pix automatically generates a new charge at each cycle, communicated to you in advance. A Founder subscriber paying by Pix keeps the price guarantee provided the charge is settled within 30 (thirty) calendar days of its due date, even if access was interrupted after the grace period set out in clause 5. If paid within that period, access is restored at the same locked price and the subscription is deemed uninterrupted for all purposes of this clause. After 30 days without payment, the preceding paragraph applies.
7. Cancellation and right of withdrawal
You may cancel your subscription at any time, through your account or by contacting us, whether you pay by card or by Pix. Cancellation ends future charges immediately, and access remains until the end of the period already paid for. There is no cancellation fee and no retention attempt.
Cancelling during the free trial. If you cancel before the trial ends, no charge is made and access remains until the end of the 7 days.
Right of withdrawal (article 49 of the Brazilian Consumer Protection Code). As this is a purchase made over the internet, you may withdraw within 7 (seven) calendar days from confirmation of the purchase, with full refund of the amount paid for the period. On plans with a free trial, this period coincides with the trial itself: if you cancel within the 7 days, nothing is charged. The right applies equally to card payment and Pix payment; with Pix, the refund is made to the same person who made the payment.
First charge after the trial. Because the 7 days of the free trial already fulfil the withdrawal period, the charge made at the end of it does not open a new refund period, and clause 8 applies.
8. Refunds
Outside the withdrawal period, amounts already paid for periods in progress are not refunded, except where required by law or in the event of a proven failure of the platform. Specific cases may be assessed through our contact channel. This also applies to the charge made at the end of the free trial.
9. Rules of use
You agree not to: share your account or credentials; copy, resell, redistribute, record or reproduce the content, the method or the analyses of the platform beyond personal use; attempt to access third-party areas or data; use bots, scraping or reverse engineering; or use the platform for any unlawful purpose. Breach may lead to suspension or termination of the account, without refund.
10. Content you upload (chord charts)
By uploading a chord chart (typed or photographed), you declare that you have the right to use it and are solely responsible for respecting the copyright in the material submitted.
Content you upload is private in your account by default and is used only to generate your analysis. You may, if you wish, choose to share it in the Users' Library, where it becomes visible to other subscribers, identified with your name. Sharing is always an act of yours, never automatic, and you may take the content down at any time.
By sharing, you declare once again that you have the right to do so and are answerable for the content you made available. Chord charts in the Users' Library have not been reviewed by Thiago Espirito Santo and are not to be confused with the VERMUS Library. We may remove, at any time and without prior notice, content that breaches these Terms, third-party rights or the law.
You grant us a limited licence, solely to store and process that content, provide the service to you and, where you choose to share it, display it to other subscribers.
11. Intellectual property
The "Como Eu Penso" method, the VERMUS and PHD — Possibilidades Harmônicas Destrinchadas marks, the vermus.com.br domain, the texts, the analyses, the layout, the code and all content of the platform belong to ESPIRITO SANTO MUSIC PRODUÇÃO E COMÉRCIO LTDA-ME or to its licensors, protected by law. A subscription grants you a personal, non-transferable right of access, not an assignment of rights. Reproduction, distribution or the creation of derivative works without authorisation is prohibited.
Materials downloaded from the platform are intended exclusively for the subscriber's personal use and carry their name and e-mail, including as a watermark, for security and usage control.
12. Availability and limitation of liability
We make efforts to keep the platform available and accurate, but it is provided "as is". The catalogue of analysed songs, the reading modes and the platform's features may be expanded, altered or replaced over time without this amounting to breach of contract, provided the essential purpose of the service is maintained. We do not guarantee uninterrupted operation and may carry out maintenance and improvements. To the maximum extent permitted by law, we are not liable for indirect damages or for learning outcomes, which depend on each person's use.
13. Changes to these Terms
We may update these Terms. Material changes will be communicated by e-mail or on the platform. Continued use after an update means agreement with the new version. The Founder plan price guarantee (clause 6) will not be reduced by a unilateral change to these Terms for anyone who is already an active Founder subscriber.
14. Governing law and jurisdiction
These Terms are governed by Brazilian law. The courts of the consumer's domicile are elected to settle any disputes.
These Terms are published in Portuguese, English and Spanish. In the event of any divergence between the versions, the Portuguese version prevails.
