This Privacy Policy describes how tjmg.online ("we", "us", or "our") collects, uses, stores, and protects your personal data when you access or use the tjmg portal and its associated applications. The tjmg portal serves as the official digital gateway for the Tribunal de Justiça de Minas Gerais (TJMG), the judiciary of the Brazilian state of Minas Gerais, accessible at www.tjmg.jus.br. This platform provides access to various judicial and administrative systems, including the Processo Judicial Eletrônico (PJe), the Sistema Eletrônico de Informações (SEI), the AI-powered Assistente TJMG, the Diário do Judiciário Eletrônico (DJe), and user experience surveys. By using our services, you agree to the practices described in this policy.

1. Information We Collect

We collect information that you provide directly to us and information that is automatically collected when you use the portal. This includes:

• Personal Identification Information: When you register for systems like SEI or log into PJe, we may collect your full name, CPF (Brazilian individual taxpayer registry), email address, phone number, professional registration number (e.g., OAB for attorneys), and digital certificate details.
• Usage Data: We automatically collect information about your interactions with the portal, such as pages visited, features used (e.g., Assistente TJMG queries, case consultations, DJe searches), time spent, and navigation patterns.

We use the collected information for the following purposes:

• To provide and maintain access to judicial and administrative systems, including PJe, SEI, and DJe.
• To authenticate users and verify credentials (e.g., digital certificates, login credentials) for secure access.
• To operate, improve, and personalize the Assistente TJMG AI tool, including generating summaries, creating judicial abstracts, and performing document analysis.
• To process and respond to your requests, such as case consultations or administrative process participation.
• To analyze usage trends and conduct user experience surveys to enhance the portal's intuitiveness and accessibility.

• To ensure the security and integrity of our systems and prevent fraud or unauthorized access.

3. Cookies and Tracking Technologies

We use cookies and similar tracking technologies to improve your experience on the tjmg portal. Cookies are small text files stored on your device. We use:

• Essential Cookies: Necessary for the portal to function, such as session management for PJe and SEI logins.
• Functional Cookies: To remember your preferences and settings, like language or accessibility options.
• Analytics Cookies: To collect anonymous usage data that helps us understand how the portal is used and identify areas for improvement.
• Third-Party Cookies: Some services integrated into the portal (e.g., AI tools, survey platforms) may use their own cookies. We do not control these third-party cookies.

You can manage cookie preferences through your browser settings. However, disabling essential cookies may affect your ability to use certain features of the portal.

4. Data Sharing and Disclosure

We do not sell your personal data. We may share your information in the following circumstances:

• With TJMG Authorities: As the official digital gateway, data may be shared with authorized TJMG personnel for judicial and administrative purposes, including case management and official publications.
• With Service Providers: We may engage third-party vendors to assist with hosting, analytics, AI model training, and survey processing. These providers are contractually bound to protect your data and use it only for specified purposes.
• For Legal Compliance: We may disclose information when required by law, court order, or governmental regulation, including compliance with LGPD and other Brazilian legal frameworks.
• With Your Consent: We may share your data for other purposes if we obtain your explicit consent.

5. Data Retention

We retain your personal data only as long as necessary to fulfill the purposes described in this policy, unless a longer retention period is required by law (e.g., for judicial records or administrative processes). Usage data and survey responses may be retained for analytics and improvement purposes for a period of up to 5 years, after which they are anonymized or deleted.

6. Data Security

We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These include encryption, access controls, secure servers, and regular security audits. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
