This site is operated as an independent publication by Luiz F. Nunes da Silva. The principles below describe how the site handles information from visitors and inquirers.
The site does not require an account, login, or registration to read any content. No personal data is collected from passive visitors beyond standard analytics — page views, referrer source, country-level location, and device type — used solely to understand site performance and reach.
If you submit an inquiry through the engagement form, the information you provide is received via Tally (the form platform) and stored only for the purpose of responding to your inquiry. Submissions are not added to marketing lists, sold, or shared with third parties.
If your inquiry leads to a formal engagement, additional information you choose to share is governed by a mutual non-disclosure agreement signed before any confidential exchange.
Email correspondence sent to addresses on this site is retained for the duration of the conversation and standard record-keeping. Subscribing to the Brazil Complexity Substack is governed by Substack's own privacy policy, which is independent of this site.
The site uses standard web analytics (Google Analytics) to understand aggregate traffic patterns and site performance. This service may set cookies and process limited information about visits in line with its own provider terms. The site does not integrate advertising trackers, retargeting pixels, or third-party data brokers.
The site links to external services — Amazon, Gumroad, Substack, Tally — each governed by their own privacy practices. These links are provided for legitimate functionality and do not include affiliate tracking on this site.
You may request information on what data is held about you, request correction or deletion, or withdraw consent for any communication, by writing to hello@brazilcomplexity.com. Requests are responded to within a reasonable timeframe.
This policy may be updated to reflect changes in tools or practices. Material changes will be reflected in the "Last updated" date above. Continued use of the site after updates constitutes acceptance of the revised policy.
