Cookies and storage on this site.

This institutional site does not use advertising cookies, ad networks or third-party analytics. What exists is described below, using the technical names in the code.

Light or dark theme

When you choose a theme, the browser stores it in local storage, under the key bmf-theme, as light or dark. If you have not chosen, the site follows the operating-system colour preference. It stays on your device: we do not send the theme in the form or to an advertiser.

To remove it, clear this site’s data in the browser settings. On the next visit the theme follows the system again until you choose.

Contact-form submit

Continuing on the form does not set a cookie on this site. The browser opens WhatsApp on +55 (22) 98802-8267 with the text built on your device. After you leave, WhatsApp (Meta) may use its own cookies and storage, under their policy.

What we do not use on this site

advertising or remarketing cookies;
embedded social-network pixels on the page;
Google Analytics, Meta Pixel or equivalent tags;
fonts or video loaded from advertising CDNs — Inter, Questrial and the hero video are files on this site.

Server logs

Hosting may record technical access (date, IP address, page, browser) for operation and security. That is typical of any site on a web server and is not a BMF marketing dashboard on this institutional site.

When you leave

Instagram, WhatsApp and the MiO, MiO4u, eMiO and EAD MiO platforms may use their own cookies. Their policies apply after you click through.
