This is the personal site of Frank Costoya. It has no accounts, forms, comments or advertising. It counts visits with two analytics services, and that is the only information it collects about you. This page was last updated on November 15, 2026.
Analytics
The site uses Google Analytics. It sets two cookies in your browser, _ga and one beginning _ga_, so that a return visit can be told apart from a new one. It sends Google the pages you view, the page that linked you here, your browser and device type, and an approximate location worked out from your IP address. Google says that Google Analytics 4 does not log or store IP addresses. Google's handling of this data is covered by its privacy policy.
The site also uses Vercel Web Analytics, which counts page views without third-party cookies. Vercel says it identifies a visit by a hash made from the incoming request, and discards it after 24 hours. Its privacy notes describe what it records.
The analytics show which pages people read. This site does not sell or share them with anyone else.
Hosting
The site is hosted on Vercel. As with any website, each request your browser makes reaches Vercel's servers with your IP address and browser details, and Vercel keeps logs of those requests to run and protect its service. Its privacy policy applies to them.
Stored in your browser
If you switch between the light and dark themes, your choice is saved in your browser's local storage under theme, so the site remembers it. The home page saves a flag called fc-intro in session storage, so its opening animation plays once per visit; the browser deletes it when you close the tab. Neither is sent anywhere.
If you write to fcostoyaprograms@gmail.com, your address and message are used only to reply to you. There is no mailing list.
Links to other sites
The links to GitHub and LinkedIn, and the buttons for sharing a post, are plain links: nothing from those sites loads on this one until you follow them, and once you do, their own privacy policies apply. The site's fonts and images are served from the site itself.
Your choices
You can block or delete cookies in your browser's settings, use a content blocker, or install Google's opt-out add-on for Google Analytics. The site works the same with all of them.
