Cookie Policy

1. What cookies are

Cookies are small text files placed on your device when you visit a website. They allow the site to remember your preferences (locale, login session) and, for some cookies, to measure site usage.

2. Which cookies SFERA uses

SFERA uses two categories of cookies:

• Essential cookies — required for the site to function. These manage your login session (when you sign in to the buyer portal), your locale preference (English / Portuguese / Russian), and your cookie banner choice itself. Essential cookies cannot be declined; without them the corresponding features will not work.
• Analytics — provided through our hosting platform's analytics provider. Analytics records session-level usage data: a session identifier, pages viewed, approximate location derived from IP, referrer, and device/browser information. We do not run advertising or retargeting on the public site, and we do not share analytics data with third-party advertising networks. You may decline analytics via the cookie banner at any time without affecting site function.

3. No advertising or marketing cookies

SFERA does not use advertising cookies, retargeting pixels, or third-party marketing cookies on the public site. The site is not monetised through advertising.

4. Your choices

You can manage cookies via the cookie banner shown on your first visit and accessible later from the footer. You can also block or delete cookies via your browser settings; doing so may affect login persistence and locale memory.

5. Updates

Material changes to cookie use will trigger a fresh cookie banner. See also Privacy Policy.
