Since the implementation of Brazil’s General Data Protection Law (LGPD) in 2020, cookie alerts on websites have become nearly unavoidable. Upon visiting a page, users are often greeted with prompts like “Accept all cookies” or “Manage cookies,” accompanied by options that aren’t always clear to the average person. These notices, frequently displayed as persistent pop-ups, aim to inform users about data collection during browsing—a practice that gained prominence with new privacy regulations. But what exactly are cookies, and how do the choices made when clicking these options affect the online experience? The answer spans from a site’s basic functionality to security and targeted advertising, directly impacting millions of Brazilians who browse daily.
Cookies are small digital files generated by websites to store information about a user’s online interactions. They can simplify tasks like remembering passwords or keeping items in a shopping cart, but they also track consumer habits to deliver personalized ads. With the LGPD, companies are now required to adopt measures ensuring greater transparency and control over this data, explaining the rise in these alerts. Enacted in 2018 and effective for over four years, the law seeks to safeguard citizens’ privacy, mandating that data controllers—such as websites and platforms—provide clear choices for users to decide what to share.
Yet, in the rush of daily life, many opt to simply click “Accept all” without exploring the alternatives. While convenient, this choice can authorize a broader collection of information, including data that spans multiple platforms to build detailed behavioral profiles. Below, the topic will be explored in depth, covering the types of cookies, how to manage them, and how new laws are reshaping online navigation in Brazil.
What cookies are and why they’re everywhere
Understanding the role of cookies is the first step to handling the alerts that pop up on websites. These files, automatically created when accessing a page, serve various purposes. Some, known as essential cookies, ensure a site’s basic operation, like loading content or maintaining an active session. Others, called functional cookies, allow platforms to “remember” user preferences, such as auto-login on social media or items left in an online shopping cart. Then there are third-party cookies, which operate across multiple sites and are widely used to track searches and display tailored ads—like that appliance ad following a user across different pages.
The surge in these alerts ties directly to changes brought by the LGPD. Before 2020, many sites collected data without prior notice, but the law shifted this landscape by requiring users to be informed about data usage. It’s estimated that over 70% of Brazilian websites have implemented some form of cookie notification since the law took effect, reflecting companies’ efforts to comply with privacy standards. In 2022, the National Data Protection Authority (ANPD) released a guide outlining best practices, such as including visible buttons to reject non-essential cookies, further driving this trend.
However, not all sites follow the same approach. While some provide detailed options to manage cookies, others merely state that continued browsing implies acceptance of data policies. This inconsistency creates confusion among users, who often don’t fully grasp what they’re agreeing to by staying on a page. The lack of standardization also highlights the challenge of adapting millions of platforms to legal requirements, a process still unfolding.
Risks and benefits in online data collection
Cookies themselves aren’t inherently dangerous. Most store only random codes to identify users without capturing personal details like names or ID numbers. Still, poor practices by some sites can create vulnerabilities. In rare instances, sensitive information such as emails or phone numbers is linked to these files, making them potential targets for cybercriminals. Experts note that third-party cookies, which cross-reference data across platforms, pose the greatest risk by exposing browsing habits to advertisers or even malicious actors.
On the flip side, the advantages are clear. A 2023 survey found that about 65% of Brazilian users prefer sites that keep their accounts logged in or save browsing preferences—features reliant on functional cookies. For businesses, these files are invaluable: statistical cookies map visitor numbers and time spent on pages, enabling improvements to user experience. Marketing cookies, though often seen as intrusive, generate billions in ad revenue by targeting ads based on specific interests.
The core issue lies in balancing convenience with privacy. On shared devices, like library computers or family phones, cookies keeping sessions active can allow unauthorized access to personal accounts. In such cases, manually logging out after use is a simple yet critical step to avoid issues. Thus, choosing between accepting all cookies or managing them reflects a trade-off between ease and control over one’s data.
How managing cookies evolved with LGPD
With the LGPD in place, Brazilian websites now offer more ways for users to control cookies. Clicking “Manage cookies” typically opens a window listing categories like “essential,” “functional,” “statistics,” and “advertising.” Each can be toggled on or off individually, except for essential cookies, which are mandatory for a site’s operation. This setup empowers users but demands attention: often, options are pre-enabled, requiring manual deactivation to limit data collection.
For instance, disabling advertising cookies stops personalized ads, though generic ones may still appear. Rejecting functional cookies might mean a site “forgets” preferences, forcing repeated logins. In 2024, analysis showed that around 40% of Brazilians managing cookies opt to disable marketing ones, signaling growing privacy concerns. The transparency mandated by LGPD has also prompted many platforms to link to privacy policies, explaining data usage in detail.
Beyond site-specific settings, browsers offer additional tools. In Google Chrome, users can block third-party cookies via the “Privacy and security” menu. This prevents cross-site tracking, though some features, like auto-login buttons, may malfunction. Other browsers, such as Firefox and Safari, provide similar options, expanding control for those prioritizing security.
Types of cookies and their practical roles
Different cookie categories play distinct roles in browsing. Here’s a breakdown of the main types and their impact:
- Essential cookies: Ensure basic site functionality, like loading pages and processing forms. Cannot be disabled.
- Functional cookies: Retain user preferences, such as auto-login or selected language, enhancing usability.
- Statistics cookies: Gather anonymous data on visits and browsing time, aiding site optimization.
- Advertising cookies: Track searches and interests to deliver targeted ads, often the focus for privacy-minded users.
These distinctions appear in management windows, though clarity varies. Advanced sites offer practical examples, while others provide vague descriptions, complicating understanding.
Timeline of data protection in Brazil
Brazil’s privacy regulations mirror a global push for transparency. Key milestones include:
- 2018: LGPD is enacted, modeled after Europe’s GDPR, focusing on personal data protection.
- 2020: Law takes effect, requiring companies to disclose data collection, including cookies.
- 2022: ANPD issues a guide with cookie-specific recommendations.
- 2024: Enforcement ramps up, with fines levied on non-compliant firms.
This timeline illustrates how the law has solidified, pressuring companies toward responsible data practices.
Options to limit online tracking
Controlling cookies extends beyond site options. Browsers and tools can bolster privacy. Blocking third-party cookies curbs intrusive ads, though it may disrupt some page functions. Using incognito mode, which discards cookies after closing, suits one-off sessions on shared devices.
Add-ons like tracker-blocking extensions for Chrome and Firefox are also rising in use. In 2023, roughly 15% of Brazilians reported using such tools, per a recent study. These, paired with manual management, offer extra protection for less exposed browsing.
LGPD’s impact on everyday browsing
The LGPD has reshaped how Brazilians interact with the web. Once a largely unregulated space, the internet now demands companies clarify their practices. In 2024, Brazil logged over 130 million active internet users, all potentially affected by these shifts. Cookie alerts, though sometimes bothersome, embody this new era where user consent takes center stage.
For companies, the challenge is balancing data collection with compliance. Fines from the ANPD, totaling millions of reais since 2023, underscore stricter oversight. Meanwhile, users wield tools and knowledge to choose how they navigate—whether valuing convenience or privacy.
