Privacy
What caio.theodoro.dev collects (essentially nothing), which third parties see a request, and how to contact the site owner about data.
This is a personal site. It is a set of static files with no accounts, no forms, no comments and no advertising, so there is very little to say here — but what there is, is said plainly rather than buried in boilerplate.
What this site collects
Nothing directly. There is no analytics script, no tag manager, no advertising pixel, no session recording and no A/B testing tool on any page. The site sets no cookies of its own and writes nothing to local storage for tracking purposes. There is no contact form, so no personal data is submitted through the site at all.
What the infrastructure sees
The site is hosted on Vercel. Like any web host, Vercel processes the request in order to serve it, which means it briefly handles your IP address, user agent and requested URL as part of normal operation and abuse prevention. That data is held by Vercel under its own privacy policy and is not exported into any analytics product by me.
Third-party requests your browser makes
Each of those hosts sees your IP address and user agent because your browser has to connect to them to fetch the asset. Blocking them degrades typography and the avatar; the site remains fully readable.
- Google Fonts (fonts.googleapis.com, fonts.gstatic.com) — serves the body typeface; Google receives the request.
- jsDelivr (cdn.jsdelivr.net) — serves the monospace typeface.
- GitHub (github.com) — serves the avatar image shown in the site header.
- Hugging Face and GitHub — only when you click through to a linked project.
Content sources and agents
Page content is pulled from a private Notion workspace at build time, not at request time, so no visitor request ever reaches Notion. Automated clients are welcome: a machine-readable index is published at /llms.txt, crawl rules at /robots.txt, a full URL list at /sitemap-index.xml, and every page has a markdown twin served either at its .md URL or through Accept-header negotiation.
Questions about data
Write to dev.caiotheodoro@gmail.com with anything data-related, including a request to remove a reference to you from a published post. This page is updated whenever the answer to any question above changes; there is no separate version history.
