This page explains, in practical terms, how this site handles data in its current technical state.

Summary

  • This blog is a static website hosted on Cloudflare infrastructure.
  • It does not require an account, login, or contact form for normal browsing.
  • The site uses Google AdSense for advertising.
  • Consent for advertising and measurement is managed by Google’s privacy messaging layer (Google Privacy and messaging, formerly Funding Choices), enabled through AdSense.
  • The site uses Google Analytics 4 for measurement, initialized with Consent Mode v2 in denied state until the visitor chooses.
  • The site stores your theme preference (light or dark) in the browser using localStorage, under the key pref-theme.
  • Comments use Disqus and load only if you click the comments button.
  • This page also covers external links and affiliate links that may appear on resource, book, or course pages.

Data processed during normal browsing

When you visit the site without loading optional third-party services:

  • the hosting and delivery platform may record basic technical data such as IP address, user agent, requested URL, and request time;
  • that data may exist in operational and security logs from the infrastructure;
  • I do not use that data for behavioral advertising, audience resale, profile sales, or personalized targeting.

Browser storage

At the moment, the site uses localStorage only to remember your theme preference.

Key used:

  • pref-theme

Purpose:

  • remember whether you prefer light or dark mode.

That storage stays on your device and is not used for cross-site tracking.

In addition, when Google’s advertising and measurement infrastructure is loaded, it may use cookies, localStorage, or similar technologies according to Google’s own rules and the site’s applicable consent state.

Comments with Disqus

Post pages do not load Disqus automatically.

The comments script is requested only if you click the button to load comments. From that point on, you start interacting with a third-party service.

If you choose to load that section:

  • Disqus may process data and set its own identifiers, cookies, or similar storage;
  • that processing is governed by Disqus’ own privacy policy and terms;
  • data may be processed outside this site under Disqus’ rules.

Official links:

The site uses Google AdSense.

The primary consent layer is Google Privacy and messaging (formerly Funding Choices), provided by Google as part of AdSense. That layer may display consent messages to visitors whose jurisdiction requires them, according to Google’s current configuration.

For visitors located in Brazil, the site displays its own LGPD banner when Google Privacy and messaging does not trigger a consent message. The site’s banner and Google’s banner are never shown at the same time. The choice made on the site’s banner is stored in localStorage under the consent.v1 key.

When Google’s advertising and measurement infrastructure is loaded:

  • Google scripts may be requested by the browser only after the consent decision is made on the applicable layer (Google Privacy and messaging or the site’s LGPD banner);
  • cookies, localStorage, or similar technologies may be used by Google according to the applicable rules and the consent state;
  • the consent state is signaled through Google Consent Mode v2 (ad_storage, analytics_storage, ad_user_data, ad_personalization), which starts as denied and is updated after the visitor decides;
  • part of the processing is governed by Google’s own documentation, terms, and privacy policy.

Relevant official links:

This blog may include links to external services, social networks, and affiliate programs.

Some book, course, or recommendation pages may use affiliate links. If you click those links and make a purchase, I may receive a commission at no extra cost to you.

Once you click an external or affiliate link, you start interacting with platforms that have their own privacy, cookie, and data-handling policies.

Data sharing

I do not sell or rent visitor personal data from this site.

Data may only be shared:

  • with technical providers required to host, deliver, or protect the site;
  • when you choose to interact with an external service such as Disqus or another third-party platform;
  • when there is a legal obligation.

Your controls

You can:

  • clear browser localStorage to remove the saved theme preference;
  • choose not to load the comments section;
  • block or limit third-party scripts in your browser;
  • avoid following external or affiliate links if you do not want to interact with third-party services.

Updates to this policy

This policy may be updated whenever the site’s technical behavior changes, for example if I change the consent stack, advertising stack, analytics, forms, or comments provider.

If that happens, this page will be revised to reflect the site’s actual behavior.
