This policy explains how the OpenGeoSGB portal, maintained by the Geological Survey of Brazil (SGB), uses cookies. It complements the SGB Personal Data Protection (LGPD) page and the gov.br Terms of Use and Privacy Notice (in Portuguese).

1. What cookies are

Cookies are small text files stored by your browser when you visit a website. They make it possible, for example, to keep you signed in, remember your preferences and protect forms against misuse.

2. Cookies used on this portal

2.1. Essential cookies

They are required for the portal to work and are always active. They are not used to track your browsing behavior.

• sessionid: keeps the session of signed-in users. Duration: 2 weeks.
• csrftoken: protects forms against cross-site request forgery (CSRF) attacks. Duration: 1 year.
• django_language: stores the language chosen in the language selector. Duration: until the browser is closed.
• messages: shows temporary messages after an action, such as saving or submitting a form. Duration: until the browser is closed.
• opengeosgb_cookie_consent: stores your choice about optional cookies. Duration: 1 year.
• JSESSIONID: keeps the session on the map server (GeoServer), when it is used. Duration: until the browser is closed.

2.2. Analytics cookies (optional)

They are only enabled if you click Accept cookies in the cookie notice. In that case, the portal loads Google Tag Manager, which may enable access statistics tools such as Google Analytics. These tools use cookies such as _ga and _ga_<identifier> (lasting up to 2 years) to count visits and understand, in aggregate, how the portal is used.

If you reject optional cookies, Google Tag Manager is not loaded and existing analytics cookies are removed. You can also disable Google Analytics on all websites with the Google Analytics opt-out browser add-on.

2.3. Third-party cookies

When you sign in with an external account (gov.br, Google or ORCID), or open links and content from other websites, those services may store their own cookies, on their own domains, according to their privacy policies.

3. How to manage your cookies

You can change your choice at any time: change my cookie preferences.

You can also block or delete cookies in your browser settings. Blocking essential cookies may prevent access to areas that require signing in and the submission of forms.
