Privacy
This is João Castro's personal site. It collects as little as possible: it has no cookies, no cookie banner and no ads.

What is measured
To know how many people visit the site and which pages matter, the site uses Vercel Web Analytics. It records page views, where the visit came from (the referring site), the country and the type of device, system and browser.
According to Vercel's documentation, this measurement does not use cookies, does not store data that identifies a person and does not follow visitors across different sites. It only runs on the official site address, not on previews or during development.
How to turn the measurement off
Use the option below to not be measured in this browser. The choice is saved only in your browser, not on any server. The site also respects your browser's "Do Not Track" and "Global Privacy Control" signals: with either one on, nothing is measured.
What stays in your browser
The site stores in your browser (local storage, not cookies) only your theme preference, the accent color (only if you change it on the Components page), the language you pick in the selector and, if you use it, the choice not to be measured. None of it is sent anywhere. On the first visit, the site uses the language of your browser to open in Portuguese or English; that reading happens in the browser itself.
Third-party content
Fonts, icons and images come from the site itself, with no external services. The Spotify player is only loaded after you press "Listen"; from then on Spotify may log the visit, under its own policy. The WhatsApp, GitHub and LinkedIn buttons only take you to those services when you click.
The Pix QR code and copy-and-paste code are generated on the site itself, without sending the key to anyone.
Hosting
The site is hosted on Vercel and its DNS is on Cloudflare. As with any hosting, the server logs technical access data (such as the IP address) in its records.
Recommendations and contact
The recommendation form does not send anything yet: what you type stays only in your browser. When sending is turned on, this page will say what is collected, why and how to ask for removal.
