Terms of Service

Revyso is a study platform for middle- and high-school students. It organises subjects, exams, assignments and tasks, and uses artificial intelligence to explain content and generate flashcards, questions, study plans and presentations.

It is a study aid. It does not replace school, a teacher, or professional advice of any kind.

These Terms are a contract between you and Gianluca Cavalieri Clerigo, trading as Revyso. By creating an account or continuing to use the service, you agree to them.

Using the service requires an account with email and password, or signing in with Google. The details you give must be true and kept up to date.

The account is personal and non-transferable. You are responsible for keeping your password secret and for everything that happens on your account. If you suspect unauthorised access, change the password and tell us.

One person, one account. Accounts created in bulk or by automation may be removed.

The minimum age is 13.

If you are under 18, you may only use the service with permission from whoever is legally responsible for you, who also takes responsibility for this agreement — including payment, if there is a subscription. In the European Union and the United Kingdom that permission is required up to age 16.

By creating an account you state that you meet the minimum age and, if a minor, that you have that permission.

RevysAI is an automated assistant. You are talking to an AI system, not to a person.

The AI gets things wrong. It can present incorrect, outdated or invented information with an air of certainty. Check anything you will use in an exam, an assignment or a decision that matters — responsibility for what you do with its output is yours.

Do not send the AI sensitive data, secrets, passwords, other people's data, or anything whose disclosure would harm you.

AI use has limits per plan and per period. Circumventing those limits, automating calls, reselling access or using the service to generate content at scale for use elsewhere is prohibited.

The full rules are in the AI Use Policy, which forms part of these Terms.

You may not use the service for:

• Illegal or violent content, sexual content involving minors, hate speech, or anything inciting harm.
• Harassment, threats, discrimination or exposing another person.
• Academic fraud where it is forbidden — using the AI to produce work your school requires to be your own is between you and your school, and we do not encourage it.
• Infringing anyone's copyright, including by uploading protected material without permission.
• Attacking, overloading, probing or trying to bypass the security of the service.
• Bulk data extraction, reverse engineering, or reselling access.

Revyso — the name, brand, interface, texts and code — belongs to its operator. These Terms give you a personal, limited, revocable, non-exclusive licence to use the service; nothing beyond that is transferred.

What you write, upload and create stays yours. You grant us only the licence needed to host, display, process and back up that content — the minimum for the service to be able to show it back to you.

You confirm you have the right to upload what you upload. Third-party material only with permission.

As for what the AI generates from your prompts: to the extent the law allows ownership in such content, it is yours to use as you wish. We claim no ownership over it. Note that AI-generated content may not be protectable by copyright in many countries, and that someone else may receive a similar answer.

There is a free plan and paid plans. What each includes and what it costs is on the plans page, with the price and currency visible before purchase.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. We neither receive nor store your card details.

Payment, billing, tax, cancellation and refund mechanics are governed by Paddle’s Buyer Terms: https://www.paddle.com/legal/checkout-buyer-terms. The rights offered in our policies and mandatory consumer rights remain unaffected.

Taxes may be added according to your country and appear at checkout before you confirm.

We may change prices. A price change never applies to a period already paid for: it takes effect at the next renewal, and you are told in advance so you can cancel first.

Subscriptions are monthly and renew automatically at the end of each period, charging the same payment method, until you cancel.

This is stated at checkout before purchase, and it is worth repeating here: if you do not cancel, you will be charged again next month.

If a charge fails, access to the paid plan is suspended until it is settled, and your account returns to the free plan without losing anything you have created.

You can cancel whenever you like, from the plans screen, without talking to anyone. Cancellation takes effect at the end of the period already paid for: you keep the plan until then, and there is no further charge.

Buyers in Brazil have 14 calendar days to withdraw from the purchase with a full refund, under art. 49 of the Consumer Protection Code. Equivalent rights exist in the European Union and the United Kingdom.

The full conditions are in the Cancellation Policy and the Refund Policy, which form part of these Terms.

We may suspend or close an account that breaches these Terms, that puts the service or other people at risk, or where the law requires it. Wherever it is reasonable, we warn first and give a chance to fix it; in serious cases suspension is immediate.

Any refund after termination is considered under our Refund Policy, Paddle’s Refund Policy and applicable law.

You can close your account at any time, from the account screen. Deletion erases your content permanently and cannot be undone. If a subscription is active, cancel it first or at the same time — deleting the account does not by itself stop billing at the payment provider.

The service is provided as is. We do not promise uninterrupted availability: there may be maintenance, provider failure and outages beyond our control.

We may change, add or remove features. If something essential to a paid plan is removed, you may cancel and receive back the unused proportional amount.

Keep your own copies of anything important. The app lets you download your flashcards, questions and presentations — use that.

To the fullest extent the law allows, we are not liable for lost profits, lost data, lost opportunity or indirect damages arising from use of the service; and our total liability is limited to what you paid in the 12 months before the event.

Nothing here excludes liability that the law does not allow to be excluded — including, in Brazil, the consumer rights in the CDC, which prevail over any clause to the contrary.

In particular, we are not liable for a school grade, exam result or academic consequence arising from AI-generated content. Check what you use.

We may change these Terms. Material changes are announced inside the app, and the date at the top changes with them. If you do not agree with the new version you may close your account; continuing to use the service means accepting it.

These Terms are governed by Brazilian law.

Before any legal step, write to the contact address: most problems are settled by email, and we commit to answering.

The forum is the consumer's place of domicile, as Brazilian consumer law requires. Consumers in the European Union and the United Kingdom keep the right to bring proceedings in their own country's courts and to use local consumer dispute-resolution mechanisms.
