This website is simple: no sign-up, no login, no store. Here is, in plain words, what happens to your data when you visit it.
The site uses Google Analytics to learn how many people visit it, which pages are viewed, from which kind of device and roughly which region. To do this, Google stores cookies in your browser.
These numbers only help me understand which content you care about. They don't identify you by name and are not sold. If you'd rather not be counted, use an ad blocker or the Google Analytics opt-out add-on.
The same Google Analytics is used on my Cairn 2e rules website (in Portuguese), cairn2e.mestredigital.online. Because of that, someone who moves from one site to the other is counted as a single visitor.
When you use the "Let's Talk" form, your name, email, subject and message are sent through Web3Forms, a service that forwards the message to my email.
I use this data only to reply to you. Your email is not added to any mailing list and is not shared with anyone.
Some parts of the site are loaded from other services: videos come from YouTube (which may use its own cookies), fonts from Google Fonts, icons and flags from public CDNs, and project images from GitHub. When loading them, your browser connects to these services, which receive technical data such as your IP address.
The site is hosted on Cloudflare, which, like any host, logs technical access data to keep the site running and protected.
Under Brazil's data protection law (LGPD), you can ask to see, correct or delete the data you sent me through the form. Just send the request through the contact form itself.
