Cookie Policy.
Which cookies and browser data this site uses, what they are for, and how to change your preferences. Last updated: November 1, 2026.
What are cookies
Cookies are small files the site saves in your browser to remember information between visits. We also use browser local storage (localStorage and sessionStorage), which works in a similar way. In this policy, we refer to all of these as cookies.
Essential: always active
Required for the site to function. They do not identify you and do not require consent.
- qv_locale: stores your chosen language (Portuguese, English, or Spanish). Duration: 12 months.
- qv_consent: stores your cookie preference, so we don't ask again on every page. Duration: 6 months.
Metrics: only with your consent
Used only if you click “Accept” on the cookie notice. They help us understand which pages are useful and how the site performs.
- qv_vid (localStorage): random browser identifier, used to count unique visitors. Remains until you clear browser data or decline metrics.
- qv_sid and qv_sid_at (sessionStorage): identify the current visit. Deleted when you close the tab or after 30 minutes of inactivity.
With these identifiers, we record visited pages, referring site, load time, IP address, approximate location, device, and browser. The data goes to our own server; we do not use Google Analytics, social media pixels, or advertising cookies. If your browser sends a “Do Not Track” signal, metrics are not collected even if you accept.
Third-party services
When you click links to WhatsApp, Instagram, LinkedIn, or Facebook, you leave our site and follow those companies’ cookie policies.
How to change your preferences
Use the “Cookie preferences” link in the footer of any page to accept or decline metrics at any time. If you decline, we delete metric identifiers from your browser. You can also block or delete cookies in your browser settings; essential cookies can be blocked, but the site may forget your chosen language.
