Terms of Use

By accessing, browsing, or otherwise using any website, application, online course platform, or digital resource operated by CESAR — Centro de Estudos e Sistemas Avançados do Recife (CNPJ 01.203.327/0001-23), you acknowledge that you have read, understood, and agree to be bound by these Terms of Use in their entirety, as well as our Privacy Policy, which is incorporated herein by reference.

If you do not agree with any part of these Terms, you must immediately discontinue your use of our services. Your continued use of the website following the publication of any modifications constitutes your acceptance of those changes.

These Terms apply to all visitors, registered users, students enrolled in CESAR's educational programs, corporate partners, and any other individuals or legal entities who interact with our digital presence. By using our services on behalf of an organization, you represent and warrant that you are authorized to bind that organization to these Terms.

CESAR grants you a limited, non-exclusive, non-transferable, revocable license to access and use our website and digital services strictly in accordance with these Terms. This license does not include any right to resell or commercial exploitation of our services; any collection and use of product listings, descriptions, or pricing; any derivative use of our services or their contents; any downloading or copying of account information for the benefit of a third party; or any use of data mining, robots, scraping, or similar data-gathering and extraction tools.

You agree to use the website only for lawful purposes and in a manner that does not infringe the rights of others or restrict or inhibit anyone else's use and enjoyment of the website. You may use our publicly accessible content for personal, non-commercial informational purposes. Access to gated resources — including online courses, research publications, software tools, and partner portals — is subject to registration and, where applicable, subscription or enrollment terms.

CESAR reserves the right to withdraw or amend any service, and to deny access to the website, without notice, for any reason, including technical issues, maintenance, or breach of these Terms. We may also introduce, modify, or discontinue any features of our digital services at any time.

All content published on CESAR's website and digital platforms — including but not limited to text, graphics, logos, icons, images, audio and video clips, course materials, research outputs, software, user interface designs, data compilations, and instructional methodologies — is the exclusive property of CESAR or its content licensors and is protected under Brazilian intellectual property law (Lei n.º 9.610/1998 — Lei de Direitos Autorais) and applicable international conventions, including the Berne Convention.

The CESAR name, logo, wordmark, and all associated brand elements are registered or common-law trademarks of Centro de Estudos e Sistemas Avançados do Recife. Nothing in these Terms shall be construed as granting any license to use CESAR's trademarks without prior written authorization.

You may not reproduce, duplicate, copy, sell, resell, distribute, publicly display, or otherwise exploit any portion of our content for commercial purposes without express written permission from CESAR. Limited quotation for academic, journalistic, or educational commentary purposes is permitted provided that clear attribution to CESAR is given and the use is consistent with fair-use principles under applicable law.

Any feedback, suggestions, ideas, or improvements you voluntarily submit to CESAR regarding our website or services may be used by us freely and without restriction or compensation to you. Submission of such material constitutes an irrevocable assignment of all associated intellectual property rights to CESAR.

As a condition of your use of this website, you agree not to engage in any of the following prohibited activities:

• Uploading, transmitting, or distributing any content that is unlawful, defamatory, obscene, fraudulent, harmful, threatening, abusive, harassing, or otherwise objectionable, as determined by CESAR in its sole discretion.
• Impersonating any person or entity, or falsely representing your affiliation with a person or entity, including CESAR staff, faculty, or institutional partners.
• Attempting to gain unauthorized access to any portion of the website, its servers, databases, or any other system or network connected to CESAR's infrastructure through hacking, password mining, or any other means.
• Introducing, transmitting, or activating any virus, Trojan horse, worm, logic bomb, spyware, adware, ransomware, or other malicious or technologically harmful material.
• Circumventing, disabling, or otherwise interfering with security-related features of the website, including any features that prevent or restrict the copying of content or enforce access limitations.
• Using the website to send unsolicited commercial communications (spam), chain letters, pyramid schemes, or any other unauthorized advertising or promotional material.
• Collecting or harvesting personal data of other users without their express consent, or using such data for any purpose not authorized by these Terms.
• Reverse engineering, decompiling, disassembling, or otherwise attempting to derive the source code of any software component of our platforms.
• Using our services to engage in, support, or facilitate any activity that violates applicable Brazilian federal or state law, or the laws of any jurisdiction in which you reside or operate.

CESAR reserves the right to investigate suspected violations of these conduct rules. If we determine that a violation has occurred, we may take any appropriate action, including issuing warnings, suspending or terminating access, and referring matters to law enforcement authorities.

Our website may contain hyperlinks to external websites, portals, partner institutions, funding bodies, and technology providers that are not owned or operated by CESAR. These links are provided solely for your information and convenience. Their inclusion does not constitute an endorsement, sponsorship, or recommendation of the linked site, its content, products, services, or operators.

CESAR has no control over the content, privacy practices, or availability of third-party websites and therefore accepts no responsibility or liability for any loss or damage that may arise from your use of them. When you navigate away from our website via a third-party link, you do so at your own risk and you should review the applicable terms of use and privacy policy of that external site.

We also cannot guarantee that the links on our website are functional at all times. If you encounter a broken or outdated link, you are welcome to notify us at the contact address provided in Section 11 so that we may take corrective action.

To the fullest extent permitted by applicable law, CESAR provides this website and all its contents, features, and services on an "as is" and "as available" basis, without representations or warranties of any kind, whether express, implied, or statutory. CESAR specifically disclaims all implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of a course of dealing, performance, usage, or trade practice.

CESAR does not warrant that the website will function without interruption, that it will be free from errors, viruses, or other harmful components, or that any defects will be corrected. We do not warrant or make any representations regarding the accuracy, reliability, completeness, or timeliness of any content published on the website, including information about our programs, services, pricing, or partners.

Some jurisdictions do not allow the exclusion of certain warranties; in such cases, the exclusions above apply only to the extent permitted by the law of your jurisdiction.

To the maximum extent permitted by applicable law, CESAR — Centro de Estudos e Sistemas Avançados do Recife, its directors, officers, employees, researchers, faculty, contractors, affiliates, licensors, and service providers — shall not be liable to you or any third party for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to loss of profits, loss of data, loss of goodwill, business interruption, or the cost of procuring substitute services, arising out of or in connection with:

• Your access to or use of, or inability to access or use, this website or any service offered through it.
• Any content obtained from, or actions taken in reliance on, information published on this website.
• Unauthorized access to or alteration of your transmissions or data.
• Statements or conduct of any third party in connection with our services.
• Any bugs, viruses, or other harmful code that may be transmitted to or through our website by any third party.
• Any errors, inaccuracies, or omissions in any content published on the website.

Where CESAR's liability cannot be entirely excluded under applicable Brazilian consumer protection law (Lei n.º 8.078/1990 — Código de Defesa do Consumidor), our total aggregate liability to you for any claim arising out of or relating to these Terms or your use of our services shall not exceed the amount you paid to CESAR, if any, in the twelve (12) months immediately preceding the event giving rise to the claim, or BRL 500.00, whichever is greater.

You agree to defend, indemnify, and hold harmless CESAR, its parent organizations, subsidiaries, affiliated research institutes, corporate partners, officers, directors, employees, faculty members, contractors, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, debts, and expenses — including reasonable attorneys' fees — arising out of or relating to:

1. Your access to or use of our website or services in violation of these Terms.
2. Your violation of any applicable law, regulation, or third-party right, including any intellectual property rights or privacy rights.
3. Any content you submit, post, upload, or transmit through our platforms, including any claim that such content infringes or misappropriates the rights of a third party.
4. Your negligent or willful misconduct in connection with your use of our services.
5. Any misrepresentation made by you in connection with your registration or use of CESAR's platforms.

CESAR reserves the right, at its own expense, to assume exclusive control of any matter subject to indemnification by you, in which case you agree to cooperate fully with CESAR's defense of such claim. This indemnification obligation survives the termination or expiration of these Terms and your use of the website.

These Terms of Use shall be governed by, construed, and enforced exclusively in accordance with the laws of the Federative Republic of Brazil, without regard to its conflict-of-law principles or rules that would cause the laws of any other jurisdiction to apply.

Any dispute, controversy, or claim arising out of or in relation to these Terms — including questions regarding their existence, validity, breach, or termination — shall be submitted to the exclusive jurisdiction of the courts of the Judicial District of Recife, State of Pernambuco, Brazil. Both parties expressly waive any objection to the venue of proceedings in those courts on the grounds of inconvenient forum or otherwise.

Notwithstanding the foregoing, CESAR retains the right to seek injunctive or other equitable relief in any competent court of competent jurisdiction to prevent the actual or threatened infringement, misappropriation, or violation of our intellectual property rights or confidential information. Users who are consumers domiciled in Brazil retain all rights afforded to them under the Brazilian Consumer Defense Code (Lei n.º 8.078/1990) and Lei Geral de Proteção de Dados (Lei n.º 13.709/2018), none of which are diminished by these Terms.

CESAR reserves the right to revise, amend, update, or replace any part of these Terms of Use at any time and at our sole discretion. When we make material changes, we will update the "Last updated" date displayed at the top of this page. In the event of changes that significantly affect your rights or obligations, we will take reasonable steps to notify you — for example, by displaying a prominent notice on our website, sending an email to your registered address, or posting an announcement in your user account dashboard.

It is your responsibility to review these Terms periodically to stay informed of any updates. Changes become effective immediately upon publication, unless we specify a different effective date. Your continued use of the website or any of our services after the posting of revised Terms constitutes your acknowledgment of, and agreement to be bound by, the modified Terms.

If you do not agree to the revised Terms, you should stop using our website and, where applicable, contact us to request deactivation of your account. We will not retroactively apply changes to disputes that arose before the effective date of a revision.

If you have any questions, concerns, or requests regarding these Terms of Use — or if you wish to report a potential violation, request content removal, or exercise any right you may have under applicable law — please do not hesitate to reach out to us. Our legal and compliance team will respond to documented inquiries within a reasonable timeframe.

Legal notices and formal correspondence must be submitted in writing. Requests submitted via email to the address above will be treated as official communications for the purposes of these Terms. CESAR will endeavor to acknowledge receipt of legal notices within five (5) business days.
