TanStack.com now sends public page activity to TanStack's namethathost service instead of Scarf. A single deferred production script records initial loads and SPA pathname changes with the reserved TanStack tracker key. The Scarf pixel and unused library IDs are removed.

The privacy policy describes company-network lookup, retention, and the tracker's Do Not Track and Global Privacy Control support. Company matches are not presented as identified people or confirmed product adoption.

Validation: pnpm test passed, including type checks, lint and 494 tests (one skipped). pnpm build passed. The collector is deployed with a 1,000/day provider cap; company enrichment awaits the ipapi.is API key.
