This document explains what cookies are, which ones exist on this site, what they are for, and how you can accept, decline, or change your choice at any time.
Cookies are small text files that a site can save in your browser to remember information between visits, such as preferences or statistical usage data. On their own, they do not reveal your name or identification documents, but they can be used to recognize the same browser over time.
Technical verification: this site, by itself, does not save any essential
cookie. Your choice about analytics cookies (accept or decline) is
stored in the browser's localStorage, under the key
mm_cookie_consent, which is a type of local storage different from a
cookie and necessary only to remember your decision.
This storage is strictly necessary for the consent banner to function and does not depend on prior authorization, since it involves no tracking and no data sent to third parties.
Only if you click "Accept analytics," the site loads Google Analytics (GA4, via
gtag.js), a Google service that sets cookies to measure general usage
statistics, such as visit counts and most-visited pages.
No personalized advertising is enabled. The code sends the
anonymize_ip parameter, inherited from Universal Analytics; according to
Google's current documentation, this parameter is redundant in GA4, which no longer
records the full IP address by default, with or without it. This site's effective
protection against Analytics is blocking the script from loading before your choice,
not that parameter.
It is important not to confuse two technically different approaches:
What this site does (basic model):
What this site did NOT implement (Consent Mode v2):
analytics_storage, ad_storage,
ad_user_data, ad_personalization) sent to
Google.The two approaches are not technically equivalent. The basic blocking used here is more restrictive in one sense (no data is sent to Google before your choice), but it does not provide the standardized signals that Google's ecosystem (Ads, remarketing) expects. Adopting Consent Mode v2 is a decision pending human approval, recorded in this site's internal decision log (currently kept in Portuguese).
The table below lists the cookies confirmed by direct browser inspection during testing on the Portuguese site, with the accepted service. No other cookie of this site's own has been identified.
| Cookie | Service | Purpose | Duration |
|---|---|---|---|
_ga |
Google Analytics (GA4) | Distinguishes browsers/visitors for aggregated usage statistics. | Up to 2 years, per Google's public documentation. |
_ga_<property-id> (e.g., _ga_88SNR74E90) |
Google Analytics (GA4) | Maintains session state specific to this GA4 property. | Up to 2 years, per Google's public documentation. |
Technical note The durations above are those stated in Google's official documentation for Google Analytics 4 and have not been independently measured by this site; the existence and names of the cookies, on the other hand, were confirmed by direct inspection in a local test environment.
On your first visit, a banner is shown with the options "Accept analytics" and "Decline analytics," with equal visual emphasis for both choices. Until you choose, no analytics cookie is created.
Use the "Manage preferences" link, permanently available in the footer
of every page of this site — in Portuguese and in English — to reopen the banner and
change your decision at any time. When you decline, existing analytics cookies
(_ga and _ga_<id>) are removed by the browser
itself.
Declining analytics cookies does not limit access to any content on the site. You can continue reading tutorials, prompts, examples, and educational material normally. The only difference is that Google Analytics does not receive browsing data from this device.
First-party cookie is one set by the marciomacedo.ia.br domain itself;
third-party cookie is set by a different domain (in this case, Google's),
even when the script was included by this site. The _ga/_ga_<id>
cookies described on this page are third-party (Google) cookies, loaded by this site only
after your authorization.
The only third-party service that sets cookies on this site, when authorized, is Google Analytics. Visual libraries loaded via CDN (Bootstrap and Bootstrap Icons) did not set any cookies of their own in the tests performed.
External Artificial Intelligence tools occasionally suggested in the prompts
(ChatGPT, Gemini, Claude, Copilot, etc.) are separate sites, accessed only when you click a
link. This site does not control, audit, or guarantee which cookies or other storage
(such as localStorage or sessionStorage) those tools use — each has
its own cookie and privacy policy, which may change at any time and should be checked
directly on each tool's site.
In addition to the options offered by this site, most browsers let you block or delete cookies manually in their privacy settings. Check your browser's documentation (Chrome, Firefox, Edge, Safari, or another) for specific instructions, including private or incognito browsing mode.
