Privacy Policy

This Privacy Policy explains how your personal information is collected, used, 'stored', and, when necessary, shared. It also describes the measures taken to ensure the security of this data, in full compliance with the Brazilian General Data Protection Law (Lei nº 13.709/2018 - LGPD).

1. Information I Collect

Voluntarily provided information: Information submitted via the contact form is collected solely for communication purposes. This includes, but is not limited to: your name, email address, and the content of your message.

Automatically collected information for statistical purposes: Your IP address is encrypted (hashed) and, along with your browser's User-Agent, is temporarily logged to count unique visitors to the website within a 24-hour period. This data is stored for no more than 24 hours in a counting system (Redis) and is then automatically deleted. No individual IP address is displayed in any reports — only aggregated data such as the total number of unique visitors per day and peak access times.

2. Use of Information

Information provided through the contact form is used solely to process and respond to your message. Automatically collected data (IP and User-Agent) is used exclusively to:

  • count unique daily visitors;
  • generate aggregated reports on peak access times;
  • filter bot traffic and ensure metric accuracy.

3. Information Sharing

As a general rule, your personal information is not shared with third parties. However, sharing may occur in specific and strictly necessary circumstances, such as:

  • Compliance with legal or regulatory obligations: when required by law, public authorities, court orders, or legal proceedings.
  • Protection of rights and security: to protect and defend my rights, this website's security, and the privacy and rights of users or the general public.

4. Cookies and Browser Tracking Technologies

This website does not use cookies or other browser-based tracking technologies (such as pixels, local storage, etc.) for identification, profiling, or advertising purposes.

The collection of information for statistical purposes, as described in Section 1, is carried out exclusively server-side, through my API and a temporary counting system (Redis). No files are installed on your device and no persistent tracking is used.

5. Data Security and Temporary Retention

I adopt appropriate security measures to protect your information from unauthorized access, improper alteration, disclosure, or accidental or unlawful destruction.

No personal information is stored permanently. All collected data — whether voluntarily provided or automatically collected, such as the IP address for statistical purposes (stored only in encrypted form) — is retained only as long as necessary for its specific purpose and is securely deleted, such as the IP address, which is erased after a maximum of 24 hours as described in Section 1.

6. Links to Third-Party Websites

This website may contain links to external websites that are not operated by me. I am not responsible for the privacy practices or content of those websites. I recommend reading the privacy policies of any external sites you visit.

7. Project Security and Intent

My projects, whether websites or apps, were developed with a focus on learning and practice. They were never intended to cause any harm. I always strive to ensure user safety and privacy, but I recommend responsible use of any software.

8. Your Rights and Choices

You have the right not to provide personal data requested in the contact form, such as your name and email address. However, refusing to provide essential information (e.g., your email address for a response) will prevent me from addressing your inquiry.

9. Acceptance of This Policy

By using this website, you agree to the terms of this Privacy Policy. Continued use of the site after any changes to this policy will be considered as acceptance of those changes. I recommend reviewing this policy regularly to stay informed of any updates.

10. Contact

If you have questions or concerns about this Privacy Policy or the handling of your information, please contact me through the form available on the website.

This policy is effective as of April 15, 2025.

Policy Update

This policy was updated on May 28, 2025 to provide a clear explanation of data collection for statistical purposes (IP address and User-Agent via API, with no use of cookies), confirm the complete absence of cookies and browser tracking technologies, refine all sections for clarity and compliance, and inform that IP addresses are stored exclusively in encrypted (hashed) format.
