Cookie Policy — RiodeJaneiro.ai Cookie Usage & Consent
Cookie Policy
Effective Date: March 22, 2026 Last Updated: March 22, 2026
This Cookie Policy explains in comprehensive detail how RiodeJaneiro.ai (“we,” “us,” or “the Platform”) uses cookies and similar tracking technologies when you visit our website. It describes what cookies are, how they function, the specific types of cookies deployed on this Platform, the purposes each type serves, the legal bases for their use, the third-party services that set cookies through our Platform, and the full range of options available to you for managing, controlling, and disabling cookies according to your preferences.
This policy should be read alongside our Privacy Policy, which provides comprehensive information about how we collect, use, protect, retain, and share your personal data, and our Terms of Service, which governs your overall use of the Platform.
What Are Cookies
Cookies are small text files that are placed on your device (computer, laptop, tablet, or smartphone) by a web server when you visit a website. Each cookie contains a string of text that typically includes a unique identifier, the domain name that set the cookie, an expiration date, and data values relevant to the cookie’s purpose. When you return to the same website or visit a website that recognizes the same cookie, the cookie is sent back to the server, allowing the site to recognize your device and recall information from your previous visit.
Cookies serve a wide range of functions in modern web architecture. They enable websites to remember your preferences and settings, maintain login sessions across page loads, track how you interact with content for analytics purposes, and deliver personalized advertising based on your browsing behavior. Without cookies, many core website functions, including shopping carts, login persistence, language preferences, and consent management, would not function as users expect.
First-party cookies are set by the website you are visiting directly, in this case riodejaneiro.ai, and can only be read by that website. Third-party cookies are set by services other than the website you are visiting, typically through scripts, tracking pixels, or embedded content loaded from third-party domains. Third-party cookies can track your activity across multiple websites that use the same third-party service.
Similar technologies that perform comparable functions to cookies and are covered by this policy include:
- Web beacons (tracking pixels): Small transparent images, typically one pixel by one pixel, embedded in web pages or emails that record when the page or email is viewed, the IP address of the viewer, and the time of the view. Web beacons are commonly used by analytics and email marketing services to track open rates and engagement.
- Local storage and session storage: HTML5 web storage mechanisms that allow websites to store data in your browser with larger capacity than cookies. Local storage persists until explicitly deleted, while session storage is cleared when the browser tab is closed.
- Fingerprinting techniques: Methods that identify devices based on a combination of browser settings, installed plugins, screen resolution, timezone, and other technical characteristics without placing a traditional cookie file. We do not engage in browser fingerprinting for tracking purposes, but some third-party services operating on our Platform may use such techniques subject to their own privacy policies.
- ETags and cache-based identifiers: HTTP caching mechanisms that can be used to store unique identifiers in your browser’s cache. We do not use ETags for tracking purposes.
Types of Cookies We Use
The cookies deployed on RiodeJaneiro.ai fall into four categories, each serving distinct purposes and operating under different legal bases. We describe each category in detail below, including the specific cookies within each category, their providers, their purposes, and their retention periods.
Strictly Necessary Cookies
These cookies are essential for the Platform to function properly and to provide the services you request. They enable core technical operations including page navigation, access to secure areas of the Platform, session management, load balancing across our server infrastructure, and, critically, remembering your cookie consent preferences so that we respect your choices on subsequent visits. Strictly necessary cookies do not collect personal information for marketing or advertising purposes and cannot be disabled through our cookie consent mechanism without fundamentally impairing Platform functionality.
Because these cookies are required for the basic operation of the Platform and the provision of services you have explicitly requested, we process them under the legal basis of legitimate interest (LGPD Article 7, IX; GDPR Article 6(1)(f)). Under the EU ePrivacy Directive (Directive 2002/58/EC as amended by Directive 2009/136/EC), strictly necessary cookies are exempt from the consent requirement because they are essential for providing a service explicitly requested by the user.
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| session_id | RiodeJaneiro.ai (first-party) | Maintains your session state across page loads, enabling consistent navigation and preventing data loss during multi-page interactions | Session (expires when browser is closed) |
| cookie_consent | RiodeJaneiro.ai (first-party) | Stores your cookie consent preferences (which categories you accepted or declined) so that we do not re-prompt you on every visit and do not place cookies you have declined | 12 months |
| csrf_token | RiodeJaneiro.ai (first-party) | Prevents cross-site request forgery attacks by validating that form submissions originate from our Platform rather than malicious third-party sites | Session |
| load_balancer | Infrastructure provider (first-party) | Routes your requests to the same server throughout your session for consistent performance and to prevent session interruption | Session |
Analytics Cookies
We use analytics cookies to understand how visitors interact with the Platform, including which pages are most visited, how long users spend reading specific articles and dashboards, which referral sources drive traffic, how users navigate between pages, which search queries are entered on the Platform, and where users encounter errors or abandon their sessions. This aggregated behavioral data helps us improve content quality, prioritize editorial coverage, optimize navigation and page layouts, identify technical issues, and make informed decisions about Platform development.
Analytics cookies collect data that is aggregated across all visitors and does not, in its aggregated form, directly identify individual users. However, because the underlying data collection involves processing identifiers such as cookie IDs and IP addresses that qualify as personal data under the LGPD, GDPR, and CCPA, we obtain your consent before placing analytics cookies on your device. Legal basis: consent (LGPD Article 7, I; GDPR Article 6(1)(a)).
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| _ga | Google Analytics | Distinguishes unique users by assigning a randomly generated identifier. Used to calculate visitor counts, session counts, and campaign data for site analytics reports | 24 months |
| ga[container_id] | Google Analytics | Maintains session state and tracks which pages are viewed within a single visit. Used to calculate session duration and page-level engagement metrics | 24 months |
| _gid | Google Analytics | Distinguishes unique users for more granular short-term analysis. Used to calculate daily active users and page-view counts within a 24-hour window | 24 hours |
| _gat | Google Analytics | Throttles the rate of requests to Google Analytics servers to prevent overloading during high-traffic periods. Does not collect user-identifiable data | 1 minute |
Google Analytics is configured on this Platform with the following privacy-enhancing settings: IP anonymization is enabled so that the last octet of your IP address is masked before storage; data sharing with Google for advertising purposes is disabled; the data retention period is set to fourteen months, after which user-level and event-level data is automatically deleted; User-ID tracking and Google Signals are not enabled.
Advertising Cookies
The Platform displays advertisements through Google AdSense and potentially other advertising networks. Advertising cookies enable these networks to serve advertisements that may be relevant to your interests based on your browsing activity across websites that participate in the same advertising network. Advertising cookies track information including whether you have visited the Platform, which pages you viewed, which advertisements you saw, whether you clicked on an advertisement, and your browsing activity on other websites in the advertising network.
Advertising cookies are set by third-party advertising services, not by RiodeJaneiro.ai directly. The data collected through advertising cookies is processed by the advertising network according to its own privacy policy and data protection practices. We do not control the data collected by advertising cookies after they are set on your device, and we do not receive personally identifiable information from advertising networks about individual users.
Because advertising cookies are non-essential and involve third-party tracking across websites, we obtain your explicit consent before allowing advertising cookies to be placed on your device. Legal basis: consent (LGPD Article 7, I; GDPR Article 6(1)(a)).
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| IDE | Google (doubleclick.net) | Used by Google AdSense and DoubleClick to serve personalized advertisements based on your browsing history across websites in the Google advertising network. Tracks ad impressions, click-throughs, and conversions | 13 months |
| NID | Stores preferences and information used to customize advertisements on Google properties and across the Google Display Network. Records a unique identifier used to remember your preferences and other information | 6 months | |
| DSID | Google (doubleclick.net) | Used to identify a signed-in user on non-Google sites and to remember whether the user has opted out of ad personalization | 2 weeks |
| test_cookie | Google (doubleclick.net) | Used to check whether your browser supports cookies. Does not store personal information | 15 minutes |
| _gcl_au | Google AdSense | Used to store and track conversions from advertisements. Records when a user arrives at the Platform through a Google advertisement to attribute conversions to specific campaigns | 3 months |
Functional Cookies
These cookies enable enhanced functionality and personalization features that improve your experience on the Platform but are not strictly necessary for core operations. Functional cookies may remember your language preference, text size settings, display preferences, previously viewed content, and form field values to reduce repetitive data entry. They may be set by RiodeJaneiro.ai or by third-party providers whose services are integrated into the Platform.
The legal basis for functional cookies depends on the specific function: cookies that directly support a service you have requested may be processed under legitimate interest, while cookies that enhance convenience but are not essential to service delivery require consent. Where consent is required, we obtain it through our cookie consent mechanism before placing functional cookies on your device.
| Cookie Name | Provider | Purpose | Duration |
|---|---|---|---|
| user_prefs | RiodeJaneiro.ai (first-party) | Stores display preferences including language selection, theme preference, and layout options so that your settings persist across sessions | 12 months |
| recently_viewed | RiodeJaneiro.ai (first-party) | Records the last ten pages you viewed on the Platform to enable “recently viewed” content recommendations and to avoid showing you the same content repeatedly | 30 days |
| form_data | RiodeJaneiro.ai (first-party) | Temporarily stores form field values (such as name and email) so that if you navigate away from a form before submitting, your entries are preserved when you return | Session |
How Cookies Are Set on This Platform
When you first visit RiodeJaneiro.ai, a cookie consent banner is displayed that explains the categories of cookies we use and allows you to accept or decline each category of non-essential cookies individually. Strictly necessary cookies are loaded immediately because they are required for the Platform to function and for the consent banner itself to operate correctly.
If you click “Accept All,” all categories of cookies (strictly necessary, analytics, advertising, and functional) are activated and the corresponding third-party scripts are loaded. If you click “Reject All” or close the banner without making a selection, only strictly necessary cookies are activated, and no analytics, advertising, or functional cookies are placed on your device. If you customize your preferences, only the categories you specifically accept are activated.
Your cookie consent preferences are stored in the cookie_consent cookie for twelve months. After twelve months, or if you clear your cookies, the consent banner will reappear and you will be asked to provide your preferences again.
Managing Your Cookie Preferences
You have multiple options for controlling which cookies are placed on your device and how your data is used by cookie-based services.
Cookie consent banner. You can update your cookie preferences at any time by clicking the “Cookie Settings” or “Manage Cookies” link in the website footer, which will re-display the consent banner and allow you to modify your selections. Changes take effect immediately: if you disable a previously accepted category, the Platform will stop loading the associated scripts, and existing cookies in that category will expire according to their scheduled duration or can be deleted manually through your browser.
Browser settings. All modern web browsers provide cookie management controls, typically accessible through the browser’s Settings, Preferences, or Privacy menu. You can configure your browser to block all cookies, block only third-party cookies, accept all cookies, or delete existing cookies on demand. You can also configure your browser to notify you whenever a cookie is being set, allowing you to accept or decline cookies individually. Note that blocking all cookies, including strictly necessary cookies, may prevent the Platform from functioning correctly, and you may be unable to access certain features or maintain a persistent session.
Browser-specific cookie management instructions:
- Google Chrome: Settings > Privacy and Security > Cookies and other site data
- Mozilla Firefox: Settings > Privacy & Security > Cookies and Site Data
- Apple Safari: Preferences > Privacy > Manage Website Data
- Microsoft Edge: Settings > Cookies and site permissions > Manage and delete cookies and site data
Google Analytics opt-out. You can prevent Google Analytics from collecting data about your visits to all websites (not just this Platform) by installing the Google Analytics Opt-out Browser Add-on, available at tools.google.com/dlpage/gaoptout. This add-on instructs your browser to prevent the Google Analytics JavaScript from sharing visit information with Google Analytics.
Google advertising opt-out. You can manage your Google advertising preferences, including opting out of personalized advertisements across all Google advertising services, through Google’s Ads Settings page at adssettings.google.com. You can also opt out of personalized advertising from all participating companies through the Digital Advertising Alliance’s opt-out tool at optout.aboutads.info, the Network Advertising Initiative’s opt-out tool at optout.networkadvertising.org, or, for users in the European Union, the European Interactive Digital Advertising Alliance’s opt-out tool at youronlinechoices.eu.
Mobile device settings. On mobile devices, you can limit ad tracking through your device’s operating system settings. On iOS, navigate to Settings > Privacy > Tracking and disable “Allow Apps to Request to Track.” On Android, navigate to Settings > Privacy > Ads and select “Delete advertising ID” or “Opt out of Ads Personalization.”
Compliance with Data Protection Laws
This Cookie Policy and our cookie consent practices are designed to comply with the cookie consent requirements of multiple data protection and electronic communications frameworks.
LGPD (Brazil). Under the LGPD, the placement of non-essential cookies that process personal data requires a valid legal basis. For analytics and advertising cookies, we rely on consent as the legal basis, obtained through our cookie consent banner before any non-essential cookies are placed. Consent under the LGPD must be freely given, informed, and unambiguous, and data subjects must be able to revoke consent at any time. Our cookie consent mechanism meets these requirements by providing clear information about each cookie category, offering granular opt-in controls, and allowing preference modification at any time through the footer link.
GDPR and ePrivacy Directive (European Union). Under the GDPR and the ePrivacy Directive (Directive 2002/58/EC as amended), prior informed consent is required before placing any non-essential cookies on a user’s device. Consent must be freely given, specific, informed, and unambiguous, and obtained through a clear affirmative action. Pre-checked boxes and implied consent through continued browsing do not constitute valid consent under GDPR. Our cookie consent banner implements these requirements by defaulting all non-essential categories to “off,” requiring affirmative opt-in for each category, and providing a mechanism to withdraw consent at any time with equal ease.
CCPA/CPRA (California, United States). Under the CCPA as amended by the CPRA, California consumers have the right to know what personal information is collected about them, including through cookies, and to opt out of the sale or sharing of personal information. While we do not sell personal information as defined by the CCPA, our advertising cookies may constitute “sharing” of personal information with advertising networks for cross-context behavioral advertising purposes. California consumers can opt out of this sharing through our cookie consent mechanism by declining advertising cookies, through the “Do Not Sell or Share My Personal Information” link in our website footer, or through a Global Privacy Control (GPC) signal sent by their browser. We honor GPC signals as valid opt-out requests under the CCPA.
PECR (United Kingdom). The Privacy and Electronic Communications Regulations 2003 (as amended) require consent before storing or accessing information on a user’s device through cookies, with an exception for cookies that are strictly necessary for providing a service requested by the user. Our cookie consent mechanism complies with PECR requirements as interpreted by the Information Commissioner’s Office (ICO) guidance.
Cookie Lifespan and Deletion
Cookies are classified by lifespan into two categories:
Session cookies are temporary cookies that exist only in the memory of your browser while it is open. Session cookies are automatically deleted when you close your browser window or tab. They are used for functions that need to persist during a single browsing session but do not need to be remembered between visits, such as maintaining your login state, storing items in a form, or managing your CSRF protection token.
Persistent cookies remain on your device after your browser is closed and are reactivated the next time you visit the website that set them. Persistent cookies have a defined expiration date, after which they are automatically deleted by your browser. They are used for functions that need to persist between visits, such as remembering your cookie consent preferences, maintaining analytics identifiers for multi-session analysis, and storing your display preferences.
You can delete all cookies stored on your device at any time through your browser’s cookie management interface. Deleting cookies will remove your stored preferences, reset your cookie consent status (causing the consent banner to reappear on your next visit), end any active sessions, and remove analytics identifiers (causing your next visit to be counted as a new unique visitor). Deleting cookies does not prevent new cookies from being set on subsequent visits unless you also configure your browser to block cookies.
Changes to This Cookie Policy
We may update this Cookie Policy to reflect changes in the cookies we use, the purposes for which we use them, the third-party services deployed on our Platform, or applicable legal and regulatory requirements. When we make changes, we will update the “Last Updated” date at the top of this page. For material changes that significantly affect how cookies process your personal data, we will provide notice through the Platform or, where required, re-prompt you for cookie consent to ensure that your preferences remain informed and current.
We encourage you to review this Cookie Policy periodically, particularly after browser updates or when you notice changes in the cookie consent banner or Platform functionality.
