Your privacy matters to DTech. This Privacy Policy explains in clear and accessible language how visitors' personal information may be collected, used, stored, and protected when browsing our blog.

The blog focuses on artificial intelligence, innovation, digital tools, and technological applications, with content designed especially for people who are beginning to explore and use these technologies.

We recognize the importance of protecting visitors' personal information and respecting their privacy.

This Privacy Policy explains what information may be processed, why it may be used, how it may be shared, and how visitors can exercise their rights.

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

Cookies are small files or identifiers that websites and browsers may use to store information related to browsing activity.

DTech may use cookies and similar technologies for essential functions, security, and optional features such as analytics or advertising when enabled.

Specific information about cookies, their purposes, duration, and available controls should be provided in the blog's Cookie Policy.

3. Purposes of Data Processing

Personal information may be processed for purposes such as:

  • Operating the website and its available features.

  • Maintaining digital security and system integrity.

  • Preventing suspicious activities and abusive access.

  • Receiving and responding to visitor messages.

  • Understanding website performance when analytics features are enabled.

  • Improving content organization and browsing experience.

  • Fulfilling applicable legal obligations.

  • Managing optional services in accordance with visitor preferences.

Personal data must not be used for incompatible purposes without meeting the corresponding legal requirements.

4. Legal Bases for Processing

Brazilian data protection law establishes different legal bases for processing personal information.

Depending on the circumstances, these may include:

Consent: when visitors freely and knowingly authorize processing for a specific purpose.

Legitimate interests: where justified, necessary, and consistent with individuals' rights and reasonable expectations.

Legal obligations: when processing is required by applicable law or regulation.

Contractual necessity: when processing is necessary for a contract or pre-contractual request involving the individual.

Exercise of legal rights: in legally permitted circumstances.

The appropriate legal basis must be determined for each processing activity.

5. Cookies and Tracking Technologies

DTech may use technologies supporting different website functions.

Essential cookies: support necessary operations, security, administrative authentication, or abuse prevention.

Analytics cookies: when enabled, may help measure visits, page views, and interactions.

Advertising cookies: may be used if advertising services requiring such technologies are activated.

Third-party technologies: external services or embedded content may use their own identifiers and storage mechanisms.

Where consent is legally required, optional technologies must respect the visitor's decision.

Rejecting optional tracking should not, by itself, prevent access to publicly available editorial content.

Additional details should be included in the Cookie Policy.

6. Audience Analytics

Understanding how visitors interact with DTech can help improve content quality, navigation, and website performance.

If audience analytics tools are enabled, information such as page views, referral sources, device characteristics, and content interactions may be processed.

Such processing must respect the stated purpose, applicable legal requirements, and visitor preferences.

Whenever appropriate, aggregated information should be preferred over unnecessary individual-level data.

7. Advertising and Affiliate Programs

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

If these services are enabled, external providers may process technical information for ad delivery, performance measurement, or commercial links.

Optional tracking technologies must comply with applicable requirements and visitor preferences.

External websites accessed through advertisements or affiliate links may apply their own privacy policies.

Commercial relationships should be disclosed when relevant and must not undermine editorial transparency.

8. Sharing Information with Third Parties

Certain website functions may require external service providers.

Depending on the services actually enabled, these may include:

  • Website hosting and infrastructure.

  • Technical maintenance and security.

  • Communication services.

  • Audience analytics.

  • Advertising and affiliate platforms.

  • Embedded content providers.

Any sharing of personal information must have an appropriate purpose and legal basis and respect applicable privacy requirements.

DTech must not sell visitor databases or personal contact lists.

Relevant providers and sharing purposes should be disclosed appropriately.

9. External Links and Embedded Content

DTech articles may contain links to external websites, AI tools, research materials, videos, and other resources.

When accessing external services, visitors may become subject to those providers' privacy policies and terms.

Embedded content may also involve technical communication with third-party servers.

We encourage readers to review external privacy policies before registering, purchasing services, or sharing personal information.

DTech does not fully control third-party privacy practices.

10. Data Storage and Retention

Personal information must be retained only for as long as necessary for its legitimate purposes, subject to applicable legal requirements and retention exceptions.

Different categories of information may require different retention periods.

For example, contact messages, security records, browsing information, and consent preferences may have different storage requirements.

When the relevant purpose ends, personal data must be deleted or processing must cease unless continued retention is legally permitted.

Specific retention periods should be established according to the systems actually used.

11. Information Security

DTech recognizes the importance of protecting personal information and maintaining a trustworthy digital environment.

Appropriate technical and organizational measures should be implemented according to the risks involved, including access controls, system maintenance, and protection against unauthorized activities.

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

Security practices should therefore be regularly reviewed and updated.

Any incident involving personal data must be handled according to applicable legal requirements and the risks identified.

12. Your Privacy Rights

Under Brazil's LGPD, individuals have rights regarding their personal data, subject to applicable legal conditions.

These may include:

  • Confirmation that personal data is being processed.

  • Access to personal information.

  • Correction of inaccurate or outdated information.

  • Anonymization, blocking, or deletion of unnecessary or unlawfully processed data.

  • Data portability, where applicable.

  • Deletion of consent-based data, subject to legal exceptions.

  • Information about relevant data sharing.

  • Information about the possibility of refusing consent and its consequences.

  • Withdrawal of consent.

13. Children's and Teenagers' Privacy

DTech publishes educational and informational technology content that may interest students and younger readers.

Personal data involving children and teenagers must be processed in accordance with applicable legal protections and their best interests.

The blog should not request unnecessary personal information from minors.

Parents and legal guardians may contact DTech to request information or clarification regarding personal data involving children or teenagers.

14. International Data Transfers

DTech covers global technology topics, and certain digital service providers may operate outside Brazil.

If personal information is transferred internationally, the processing must comply with applicable legal requirements and safeguards under the LGPD and ANPD regulations.

Publishing international content does not, by itself, mean that visitors' personal information is transferred abroad.

15. Changes to This Privacy Policy

This policy may be updated to reflect changes in website functionality, service providers, technologies, or applicable legal requirements.

Material changes should be communicated appropriately, particularly when they affect processing purposes or visitor rights.
