Privacy

How we handle data #

All data processing follows Brazil’s General Data Protection Law (Law 13,709/2018), based either on your consent or on legitimate interest, depending on the purpose.

What we collect and why #

Reports. To download a report, we ask for a short sign-up: your name, e-mail and some context information. This data is used to personalize the material, learn who uses it and build a contact base — which enables newsletter sign-up, announcements of new publications, targeted marketing and the release of new materials that may interest you.

Contact. The contact form collects what you write in it and serves one purpose only: to reply to you. Contact messages never become a mailing list without your consent.

Browsing. The site measures audience in aggregate, with no tracking cookies and without identifying individual visitors.

To operate, this site uses service providers — hosting, storage, e-mail delivery and material generation. These providers process data on our behalf, only for the purposes described above, and some may be based outside Brazil. Beyond that, no data is sold or passed on to third parties for commercial purposes.

Your rights #

At any time, and at no cost, you can:

opt out of any e-mail list;
request deletion of your data;
withdraw your consent.

For all of this, simply talk to me — requests are answered within 15 days. E-mail cancellations can also be made through the opt-out link in the footer of e-mails, where automatically available.

Children and adolescents #

Nothing here is directed at children. If a child’s data has been collected, talk to me and it will be deleted.

Controller #

The controller of the data processed by this site is Daniel Castro. The channel for any privacy matter — requests, questions or complaints — is the contact page .
