A small personal site should collect very little.
This site has no account system, contact form, advertising tracker or mailing-list database. If you email me, I receive the details you choose to put in that message and use them to reply to you. You can ask me to delete that correspondence at any time, subject to any record I must retain for a legal or contractual reason.
I use Vercel Web Analytics to understand aggregate page use. Vercel states that this service records aggregated page-view information without third-party cookies or persistent cross-site identifiers. It derives a visitor hash from request data for daily aggregation and discards that hash after 24 hours. Recorded fields may include the route, filtered query parameters, time, referrer, coarse location, browser, operating system and device type. Read Vercel's Web Analytics privacy information (opens in a new tab).
Links to project sites, GitHub, LinkedIn and other external services take you to systems with their own privacy practices. The downloadable vCard is a static public file and is excluded from search-engine crawling; that exclusion is not an access control.
