Terms of use

WeBest is an AI-powered study app for iOS and Android, provided by Caterina Boff Costa LTDA, registered in Brazil under CNPJ no. 68.564.652/0001-92, with its registered office at Estrada Tenente Marques, 6765, Santana de Parnaíba - SP, CEP 06530-001, Brazil. In these terms, “WeBest”, “we” and “our” refer to that company, and “you” is the person using the app.

These Terms of Use apply to the WeBest app and to shared learning path links. How we look after your personal data is explained in the Privacy Policy, which is part of these terms.

By creating your account, you confirm that you have read and accept these terms and the Privacy Policy. If you don't agree, don't use WeBest.

WeBest is for people aged 13 and over. At sign-up we ask for your date of birth and don't accept anyone who states they are under 13. If we find out that an account belongs to someone under 13, we delete it.

If you are 13 to 17, you may only use WeBest with the knowledge and permission of a parent or legal guardian, who should read these terms and the Privacy Policy with you.

• Give accurate information at sign-up, including your date of birth.
• Your account is personal: don't share it or use someone else's.
• Keep your password secret. If you suspect misuse, change your password and let us know through the help page.
• You are responsible for what is done in your account, except when the problem is caused by a failure on our side.

An account created with false information, such as an age that isn't yours, may be closed.

Zero tolerance: it is forbidden to publish or share offensive, discriminatory, sexual, violent or illegal content, or content that violates the rights of others, or to use WeBest to harass people. We may remove the content, disable links and block the account without notice. We review reports within 24 hours.

It is also not allowed to:

• use WeBest for illegal purposes, to deceive people or to impersonate someone else;
• upload materials you don't have the right to use, such as copyrighted works without permission;
• expose other people's personal data, such as documents, addresses or phone numbers;
• try to access other people's accounts or data, get around usage limits or disrupt the service;
• use bots or scripts to access the app, copy content in bulk or resell access;
• use WeBest's AI to create content these terms forbid, or try to get around its safeguards.

If you break these rules, depending on how serious it is, we may remove the content, disable sharing links, limit features or block the account. In serious or illegal cases, we may also keep the information needed and notify the authorities, as the law allows or requires.

You can create a public link to a learning path. Anyone with the link sees only its structure (topic, objective, goals and steps) and the author name you choose to display, if any; never your progress, your notes or your account data.

• You are responsible for what you share, including the author name.
• Before creating the link, the app asks you to accept these terms.
• Before publishing, an automatic filter checks the path's text and the author name. If it finds inappropriate content, the link is not created; you can revise it and try again. The filter helps, but it doesn't replace reports or our review.
• Anyone can report a shared learning path: in the app, with “Denunciar trilha” (Report path), or through the help page.
• We review reports within 24 hours. If the path violates these terms, we remove the content, disable the link and may block the account of whoever published it.
• You can disable your links whenever you want, right in the app.

Someone who copies a shared path into their own account keeps that copy, which does not carry your name, your progress or your account data.

Learning paths, sessions, exercises, feedback, tutor answers and documents are generated by artificial intelligence.

• AI can make mistakes. It may produce incorrect, incomplete or outdated information. Check anything important against reliable sources.
• The content is educational and is not professional advice. Don't use it in place of advice from a qualified professional on health, legal or financial matters, or in other regulated fields.
• Passages you ask to hear are processed by Inworld, in the United States, under a separate consent the app asks for the first time you tap “Ouvir” (Listen); content for other AI features is processed by OpenAI, in the United States, under the Privacy Policy and the consent the app asks for before first use. You can withdraw each one anytime in “Perfil → Consentimento de IA” (Profile → AI consent).
• Estimated levels and feedback are automatic and are meant to guide your studies. You can adjust your learning path and ask for a review of decisions made solely by automated means.

WeBest is free. To keep the service sustainable and fair for everyone, each use of AI features consumes AI credits, and each account has a plan (today, Grátis) with monthly limits.

• The app shows, in “Perfil → Seu plano e uso” (Profile → Your plan and usage), how much of each limit you used this month. The limits start over every month; the Grátis plan also has a daily AI credit limit, and the natural voice has its own allowance in minutes.
• If you reach a limit, the matching feature is paused until it starts over (the next day or the next month); reviews, streaks and progress keep working.
• Plan limits don't carry over from one month to the next. Credits are not sold, have no cash value and can't be transferred; extra credits our team grants are valid for the period stated.
• We also limit how often features can be used, to prevent abuse. If you hit one of these limits, wait a little and try again.
• We may adjust the limits to protect the service. If we ever start charging for a feature, we will tell you beforehand, and nothing will be charged without your agreement.

The WeBest brand, the app, this website, the design and the software belong to us or to our licensors. You get a personal, free, non-exclusive and non-transferable license to use the app for your studies while your account exists.

Your content stays yours. The notes, materials and text you upload are yours. You authorize us to store and process them only to provide the service, as described in the Privacy Policy. When you share a learning path, you allow anyone with the link to view it and copy it into their own account.

You are free to use the content the AI generates for you in your studies.

Only upload materials you have the right to use. If any content on WeBest violates your rights, let us know through the help page.

You can delete your account at any time, right in the app: “Perfil → Excluir conta” (Profile → Delete account). Deletion is immediate and permanent, and the links to the paths you shared stop working. What we keep after that, and for how long, is in the Privacy Policy.

We may suspend or close an account that violates these terms or the law, or when a court order or an authority requires it. Except in serious, illegal or zero-tolerance cases, we will tell you beforehand and explain why. If you think there was a mistake, talk to us through the help page.

We may also discontinue WeBest or one of its features. In that case, we will give you reasonable notice in the app.

We work to keep WeBest running well and safely, but the service may have interruptions, failures or errors, including in AI answers. When that happens, we will do our best to fix it quickly.

We are not liable for damage caused solely by you or by third parties, such as using AI content in place of professional advice, content published by other people or breaches of these terms.

Nothing in these terms limits the rights that Brazil's Consumer Protection Code (Código de Defesa do Consumidor, Law no. 8,078/1990) and other laws give you, or excludes our liability where the law does not allow it to be excluded.

We may update these terms when the service or the law changes. The version date is at the top of the page.

If the change is significant, we will tell you in the app before it takes effect, highlighting what changed. Some changes may require you to accept the new version to keep using the app or to share learning paths. If you don't agree, you can delete your account at any time.

These terms are governed by the laws of Brazil. As a consumer, you may bring legal action in the courts of your place of residence, as guaranteed by the Consumer Protection Code (art. 101, I).

Before going to court, talk to us through the help page: almost everything can be solved there. You can also contact consumer protection bodies, such as Procon.

These terms were written in Portuguese and are also available in English and Spanish. If the versions differ, the Portuguese version prevails.
