A small personal site should collect very little.
This site has no account system, advertising tracker or mailing-list database, and no form that submits anything to it. 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.
The co-founder invitation page offers an optional introduction builder. Its questions look like a form, so to be clear about what happens: your answers stay in the current browser tab, and nothing is sent to this site, saved or recorded. You can copy the draft, download it as a plain-text file, or open it in your email application and then decide whether to send it. Leaving or reloading the page clears what you wrote.
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.
