What cookies are
Cookies are small text files stored by your browser when you visit a website. They allow a site to remember information between page loads, such as your preferences or whether you have already seen a notice. They are not programs and cannot access other files on your device.
Two details are worth keeping straight. First, a cookie belongs to the domain that set it, so a file written by primavita.id is not readable by an unrelated site you open in another tab. Second, cookies hold only the amount of information the site chose to write into them — usually a short label, a session identifier, or a preference value. If you clear the cookies stored in your browser, a site simply treats you as a new visitor on your next load and asks again for any settings it had remembered.
Your browser decides where these files live and how long they survive. A session cookie disappears when you close the browser window; a persistent cookie stays until its own expiry date passes or you remove it yourself.
First-party and third-party, in plain terms
A first-party cookie is set by the site you are actually visiting — here, primavita.id. A third-party cookie is set by a different service whose content or measurement code is embedded in the page. The distinction matters because you can allow one kind and block the other in most modern browsers, and because responsibility for each file sits with the party that created it. The sections below describe which of the two groups applies to this site and what each one is used for.
