# Privacy

> This notice explains the limited information processed when you browse cleisson.com or contact Cleisson de Oliveira Moura directly.

## Information this site processes

This portfolio does not provide user accounts, comments, payments, advertising profiles, or a web contact form. The site may process ordinary request information needed to deliver a page, such as an IP address, browser or device details, requested URL, referral information, timestamps, and diagnostic or security events through its hosting infrastructure. Requests to the public REST API or Model Context Protocol (MCP) endpoint may also contain client metadata, operation, tool, or prompt names, a locale, search topics, or a project slug. These endpoints use this information only to operate and protect these read-only interfaces and return public portfolio evidence; they have no account database or server-side language model.

If you choose to send an email, the message, sender details, attachments, and any information you include are processed by the email services used by you and by Cleisson. Send only the information needed for the professional inquiry and avoid confidential credentials or sensitive personal data.

## Cookies, analytics, and performance

The site uses a locale cookie to support language detection and routing, and a theme cookie when you choose light or dark mode. Each can remain for up to one year. They support requested site behavior rather than advertising. Vercel Analytics and Speed Insights are enabled to understand aggregate usage, page delivery, and performance; Vercel may process technical request and device information under its own terms.

Hosting and security providers may retain operational logs according to their own policies. This site does not sell personal information and does not add third-party advertising trackers. Links to LinkedIn, GitHub, and other external resources leave this site and are governed by those services' privacy practices.

## Questions and choices

You can clear the locale and theme cookies in your browser, block optional client-side features, or browse the server-rendered content without JavaScript. REST API and MCP requests and their limited arguments may appear in ordinary hosting, rate-limit, diagnostic, or security logs; do not send a confidential job description, credentials, or sensitive personal data. For a privacy question about this site or a direct email you previously sent, use the contact page and describe the request without including additional sensitive information.
