Protection and security of personal data

Braskem has adopted appropriate technical and organizational measures to protect personal data against loss or any form of unlawful processing. Some information we collect for registration on the website, through physical or digital forms, in-person or remote services, applications, internal systems and ERPs, cookies, security cameras, authorized partners, and public sources (always respecting the principles and legal bases provided in the LGPD) may be protected by information security measures or passwords so that only authorized persons at Braskem have access to this personal information. Braskem recommends that you do not disclose your password to anyone. Braskem will never request personal data without a specific reason in a pre-existing relationship or your password by unsolicited phone or email. When browsing Braskem's website, you should also remember to log out and close your browser window when you finish a browsing session. If you are using a Braskem application with login and password, do not share your password or login with anyone. This helps minimize the chances of others accessing your personal information and electronic correspondence, especially if you share your computer with someone or are using a public computer.

No data transmission over the Internet is 100% secure. Therefore, while Braskem makes every effort to protect your personal information, Braskem cannot ensure or guarantee the security of any information transmitted to Braskem or provided during website navigation, and it is at your own risk. You should always be careful and responsible when browsing online.

On the other hand, the user should be aware that they are solely responsible for qualifying their information as private or not, and thus decide, at their own risk, to provide it during online navigation.

You should also be aware that privacy rights are independent and do not confuse with intellectual property rights, image rights, rights to honor and reputation, and other personality rights, and therefore, not all information you provide on the website will be protected by the same.

The conditions governing the confidentiality of Braskem's information on the website are regulated in the Terms of Use of the website, and Braskem recommends that you consult them in case of any doubt.

Braskem reserves the right to judge, at its sole discretion, except in case of a decision by a competent authority, the appropriateness of information requests from one person made by another person under the pretext of common interest for the latter.

The website does not provide Internet access, and Braskem should not be requested to provide information about the data flow of users accessing the website, except in case of determination by competent authorities, at Braskem's discretion
