Privacy

This page describes, honestly and completely, the usage data this site collects: an anonymized, aggregate-only pipeline for tool calls and chat questions, and page-level analytics for the site itself. Nothing here is public — see the sections below for exactly what is and isn't stored.

What's collected

Aggregated tool-call usage: which tool was called, from which surface (the public MCP endpoint or this site's chat), and its outcome.
Question-theme labels for chat questions — a fixed set of topic buckets (e.g. experience, skills, availability), not the question text itself.
Coarse response-latency buckets (e.g. "under 2s"), never an exact millisecond value.
Page-level analytics via Vercel Analytics: page views and web vitals for this site, cookieless and first-party.

What's never collected

Raw question text or chat message contents — only a theme label, never the words asked.
Tool call arguments or results.
IP addresses.
Identities, session identifiers, user agents, or any other value that could re-identify a visitor.
Third-party advertising or tracking cookies of any kind.

Retention

Every usage event is deleted after 90 days. Nothing is kept longer.

Tracking cookies

No third-party advertising or tracking cookies are set anywhere on this site.

Third-party services

Vercel — hosting this site, and Vercel Analytics for page-level traffic
