The availability of each feature and its limits vary according to the User's contracted Plan.

4. Registration and account

Eligibility. The User declares to be at least 18 years old and an education professional (teacher, instructor, pedagogical coordinator, or equivalent role).

Truthfulness. The User commits to providing true, complete and up-to-date data at registration. False or misleading data may result in suspension or termination of the account.

Credentials. The User is responsible for safeguarding their credentials (password or linked Google account). Any action taken with the authenticated account is the User's responsibility. In case of unauthorized use, the User must immediately notify suporte@qprova.com.

Authentication methods. The Platform accepts registration/login via email and password or via Google OAuth. The User may terminate the account at any time by request to support.

5. Plans, billing and cancellation

Plans. QProva offers a free plan (Free) and paid plans (Premium and Master), with monthly usage limits for AI, number of templates, questions and evaluations. The current limits are described on the Platform.

Billing. Paid plans are charged on a recurring basis (monthly or annual) by the Stripe payment processor. The User authorizes automatic charges to the registered payment method at each cycle until cancellation.

Price changes. The Provider may adjust prices with 30 days' prior notice by email to the User. The User may cancel before the new price takes effect at no cost.

Right of withdrawal. Under Article 49 of the Brazilian Consumer Protection Code, the User has a 7-day right of withdrawal from the first contracting of a paid plan, with full refund. The request must be made via suporte@qprova.com.

Cancellation. The User may cancel automatic renewal at any time in the billing area of the Platform. Access remains available until the end of the already paid cycle, with no proportional refund of the unused period.

Delinquency. In case of persistent billing failure (more than 7 days after the renewal attempt), the Plan is downgraded to Free and access to premium features is suspended until regularization.

6. User Content

Ownership. The User retains all rights over the Content they create on the Platform. QProva does not claim ownership over User Content.

License granted to QProva. For the Platform to operate, the User grants the Provider a non-exclusive, royalty-free, worldwide and revocable license to store, process, display and transmit the User Content through the systems necessary for the service (own servers and sub-processors listed in the Privacy Policy).

Revocation of license. The license is revoked upon deletion of Content by the User or upon termination of the account, subject to section 8 (Public Bank) and the Privacy Policy regarding backups and legal retention.

Responsibility. The User declares to hold rights over the Content they submit (texts, images, formulas) and is responsible for any infringement of third-party rights.

7. Artificial Intelligence — Generated Content

Assistance tool. The Platform's AI is an assistance tool for educational content creation. The User, as an education professional, is responsible for reviewing, validating and adapting the AI-Generated Content before any use in classrooms, evaluations or other educational contexts.

No quality guarantee. The Provider does not guarantee that AI-Generated Content will be accurate, free from bias, suitable for the curriculum, or appropriate for any specific purpose. AI models may produce incorrect, outdated or biased responses.

Automatic Public Bank. By generating questions with the Platform's AI, the User agrees that these questions will be automatically included in the Public Bank with attribution to their display name, as described in section 8. The User may mark an AI-Generated question as private at any time through the interface, removing it from the Public Bank (without retroactively affecting copies already cloned by third parties).

Third-party providers. AI requests are processed by third-party providers (including, but not limited to, OpenAI, Anthropic and Google), as described in the Privacy Policy.

8. Public Question Bank

Operation. The Public Bank is a repository of questions shared between Premium and Master subscribers. Published questions are visible and may be cloned to other subscribers' personal banks.

Attribution. Questions published in the Public Bank show the display name of the User who published them.

AI-Generated Content. Automatically enters the Public Bank at generation time, as per section 7.

Manual Content. Not published by default. The User may opt to publish a manual question via a toggle in the personal bank interface. Publishing implies agreement with the conditions of this section.

Making private. The User may make a public question private at any time. The question disappears from the Public Bank, but copies already cloned by other Users remain in their personal banks (turning private does not retroact).

Account deletion. Upon account deletion, the User's public questions remain available in the Public Bank, but attribution is changed to "User removed". For complete removal of public questions, the User must request it in advance from the Data Protection Officer (see Privacy Policy).

9. Prohibited conduct

The User is prohibited from, under penalty of suspension or termination without proportional refund:

• using the Platform for illegal, fraudulent or public-order-violating purposes;
• generating, storing or publishing discriminatory, offensive, violent, sexually explicit, or harassment-related content;
• producing deepfakes, forgeries or content that may mislead third parties about facts or persons;
• performing massive scraping, unauthorized automation, or attempting to circumvent technical Plan limits;
• abusing the AI API with prompt injection, jailbreaks, or non-educational use;
• republishing third-party content without authorization or adequate license;
• sharing credentials or allowing unauthorized parties to use the account;
• attempting to access other Users' data or restricted areas of the Platform's systems.

Serious violations result in termination without refund. Minor violations may be handled with a warning and correction period, at the Provider's discretion.

10. Availability and absence of warranties

No contractual SLA. In this version of the Platform, the Provider does not offer a contractually guaranteed service level. The Provider will use reasonable efforts to keep the Platform available.

Maintenance. Scheduled maintenance will be announced in advance whenever possible. Emergency maintenance may occur without prior notice.

Third-party dependencies. The Platform depends on third-party services (Supabase, Stripe, AI providers, Sentry). The Provider is not responsible for unavailability, errors or losses arising from failures of those providers, as described in the Privacy Policy.

Content "as is". All AI-Generated Content is provided "as is", with no warranties of accuracy, suitability or fitness for any purpose.

11. Limitation of liability

To the maximum extent permitted by applicable law, the Provider shall not be liable for:

• indirect damages, loss of profit, loss of opportunity, loss of data caused by the User, or moral damages arising from the use of AI-Generated Content;
• acts or omissions of other Users, including content published in the Public Bank;
• pedagogical, academic or evaluative decisions made based on content generated by the Platform.

Contractual cap. The Provider's total liability to the User, in any case, is limited to the amount actually paid by the User to the Provider in the 12 (twelve) months preceding the triggering event.

12. Platform intellectual property

The QProva software, layout, brand, logo, visual identity and marketing materials are the property of the Provider or its licensors. The User receives a non-exclusive, non-transferable and revocable license to use the Platform while their subscription is active, exclusively for the purposes set out in these Terms.

Decompiling, reverse engineering, copying substantial portions of the code, or using the QProva brand without written authorization is prohibited.

13. Changes to these Terms

Material changes. Changes affecting User rights (for example, billing policy, scope of the Public Bank, limitations of liability) will be communicated by email at least 30 days before they take effect. The Platform will require a new acceptance via a specific gate before continued access.

Minor corrections. Wording adjustments, clarifications, fixes to grammatical errors or references (without changes to rights) take effect immediately, without re-acceptance.

Current version. The current version of these Terms is always available at /terms. Previous versions may be requested via suporte@qprova.com.
