Cookie Policy

At DTech, we believe understanding how websites use your information should be as simple as learning about technology. This Cookie Policy explains what cookies are, how they work, why they may be used, and what choices visitors have to protect their privacy. Our commitment is to provide a transparent, secure, and accessible browsing experience while respecting applicable Brazilian data protection legislation.

1. Introduction

DTech is an independent blog created by Jeferson Dantas, a software developer based in Aracaju, Sergipe, Brazil.

Our content focuses on artificial intelligence, innovation, digital tools, and technological applications, particularly for people beginning to explore and use these technologies.

We believe visitors should understand how their information may be processed when accessing our website.

This Cookie Policy explains the types of cookies and similar technologies that may be involved in DTech's operation, their purposes, and the controls available to visitors.

Personal data processing involving these technologies must comply with Brazil's General Data Protection Law (LGPD), Law No. 13,709/2018, and other applicable regulations.

This policy complements our Privacy Policy.

2. What Are Cookies?

Cookies are small files that websites may store in a visitor's browser.

They can help websites remember preferences, maintain sessions, support security measures, and operate certain features.

For example, a cookie may remember a visitor's selected language.

Other cookies may support audience measurement, website performance analysis, or advertising services.

Not all cookies serve the same purpose. Some may be essential, while others are optional and subject to applicable legal requirements.

Websites may also use similar technologies, including local browser storage, scripts, and technical identifiers.

When these technologies involve personal information, relevant data protection requirements apply.

3. Categories of Cookies

Cookies may be classified according to their purposes.

The following categories describe technologies that may exist on websites such as DTech. They do not confirm that every category is currently enabled.

Essential Cookies

Essential cookies support necessary website operations and security.

They may be used for:

  • Maintaining essential website functions.

  • Administrative authentication.

  • Preventing unauthorized access.

  • Protecting against automated abuse.

  • Remembering privacy-related choices.

These technologies may rely on legal bases other than consent when appropriate.

Preference Cookies

Preference cookies may remember choices made by visitors, including:

  • Selected language.

  • Display preferences.

  • Certain browsing settings.

Their legal basis depends on their specific purpose and implementation.

Analytics Cookies

When enabled, analytics cookies may help understand how readers interact with DTech.

They can support the measurement of:

  • Website visits and page views.

  • Popular articles.

  • Traffic sources.

  • Device characteristics.

  • General browsing patterns.

  • Website performance.

Analytics involving consent-based technologies must respect visitors' choices.

Advertising and Marketing Cookies

If advertising services are enabled, external providers may use cookies or identifiers to display advertisements, measure performance, or support other advertising functions.

These technologies may involve browsing information, depending on the provider and its configuration.

Behavioral advertising and other optional technologies requiring consent must respect the visitor's decision.

Displaying advertisements does not necessarily mean that personalized advertising is being used.

4. First-Party and Third-Party Cookies

Cookies may also be classified according to their source.

First-party cookies are set by the website's domain and may support DTech's own functionality.

Third-party cookies may be set by external services integrated into the website, such as video platforms, analytics providers, or advertising networks.

External providers may maintain their own data processing and retention practices.

When third-party services are enabled, relevant purposes and data-sharing practices should be disclosed appropriately.

DTech does not fully control external websites after visitors leave the blog.

5. Audience Analytics and Website Improvement

Understanding how readers interact with DTech may help improve the quality and organization of its content.

If analytics systems are enabled, they may process information such as:

  • Pages and articles visited.

  • Access dates and times.

  • Referral sources.

  • Device and browser characteristics.

  • Browsing language.

  • Sessions and page views.

  • Interactions with enabled website features.

Data collection must respect principles such as transparency, necessity, security, and purpose limitation.

Where appropriate, aggregated information should be preferred.

Information collected for audience measurement should not automatically be repurposed for behavioral profiling or personalized advertising.

6. Interactive Features and Security

Certain interactive features may require technical identifiers to maintain their integrity.

If DTech offers article ratings, forms, or other interactive resources, technical measures may help prevent repeated submissions, unauthorized access, or automated abuse.

These mechanisms should be limited to what is necessary for their purposes.

Information used to protect a feature should not automatically be repurposed for unrelated tracking.

Pseudonymous or hashed identifiers may still qualify as personal data when individuals can be identified or made identifiable.

7. Advertising and Affiliate Links

DTech is an independent editorial project and may use advertising or affiliate programs to support its activities.

If such services are enabled, external providers may use technologies related to advertisement delivery, performance measurement, attribution, and fraud prevention.

When visitors follow commercial links, destination websites may apply their own privacy and cookie policies.

The use of these technologies must comply with applicable consent requirements and other legal obligations.

Relevant commercial relationships should be clearly disclosed.

8. Embedded Content and External Platforms

DTech articles may reference videos, research, artificial intelligence tools, documents, and external resources.

When third-party content is embedded directly into a page, loading it may establish a connection with the provider's servers.

Depending on the integration, technical information such as IP addresses, browser characteristics, and referring pages may be transmitted.

Where consent is required, embedded services must respect the applicable requirements before loading.

External websites operate under their own privacy policies.

9. Consent and Cookie Preferences

When the use of cookies or similar technologies depends on consent, DTech must respect visitors' decisions.

If consent-based optional technologies are used, the preference management system should provide clear choices, which may include:

Accept All: authorize the optional categories presented.

Reject Optional Cookies: decline technologies requiring consent.

Manage Preferences: select available categories individually and save the choices.

Strictly necessary cookies may remain active when supported by an appropriate legal basis.

Closing a banner, failing to respond, or continuing to browse will not automatically be treated as consent.

Access to public editorial content should not depend on accepting optional tracking.

These choices must be supported by a functioning preference management mechanism when the relevant technologies are used.

10. Changing or Withdrawing Consent

When DTech uses optional consent-based cookies, visitors must have an accessible way to modify or withdraw their choices.

If a Cookie Preferences control is available, it may be used to review previous authorizations.

Withdrawing consent must stop new processing activities based on the withdrawn authorization, subject to applicable legal conditions.

Visitors may also manage or delete cookies through their browser settings.

However, deleting browser cookies does not necessarily remove information previously stored in other systems.

For privacy-related questions or requests, visitors may contact DTech by email.

11. Storage and Cookie Duration

Cookies may have different lifespans.

Session cookies generally support activities during a browsing session, depending on their implementation.

Persistent cookies may remain stored for a defined period or until deleted.

Their duration depends on their purpose and technical configuration.

The lifespan of a cookie is not necessarily the same as the retention period of related records stored on a server.

Specific retention periods must respect the purposes and legal requirements involved.

An inventory of the cookies actually used by DTech should identify their names, providers, purposes, and durations.

12. Information Security

Cookies and technical identifiers must be handled with security measures appropriate to their risks.

DTech recognizes the importance of protecting personal information and preventing misuse.

Relevant principles include:

  • Collecting only necessary information.

  • Explaining processing purposes.

  • Protecting against unauthorized access.

  • Respecting visitors' preferences.

  • Limiting storage to justified periods.

  • Reviewing the technologies and integrations in use.

No internet-connected system can be guaranteed completely free from security risks.

Privacy and security measures should therefore be reviewed as the website evolves.

13. Your Privacy Rights

Under Brazil's LGPD, individuals have rights concerning their personal information.

Subject to applicable legal conditions, these may include:

  • Confirmation of personal data processing.

  • Access to personal information.

  • Correction of inaccurate information.

  • Blocking, anonymization, or deletion where legally applicable.

  • Information about data sharing.

  • Withdrawal of consent.

  • Objection to processing conducted unlawfully.

  • Other rights established by applicable legislation.

Limited information may be requested to verify identity and protect against unauthorized disclosure.

Additional information is available in DTech's Privacy Policy.

14. Changes to This Cookie Policy

This policy may be updated to reflect changes in website features, technology providers, data processing practices, or applicable laws.

Material changes affecting cookie purposes or consent conditions should be communicated appropriately.

New consent must be obtained whenever legally required.
