Every visitor now gets a stable identity the moment they land, set and signed on the server. It links their sessions across visits so attribution and analytics stay accurate, and it does this without IP tracking or device fingerprinting.

Use cases

  • Accurate attribution - tie a later purchase back to the first click, even across separate visits
  • Cleaner analytics - one returning person counts as one person, not several new sessions
  • Privacy-respecting by design - no fingerprinting, so you stay on the right side of visitor trust

Impact

You get the cross-session continuity you need for real funnel math without the fragility and privacy cost of fingerprinting. Because the identity is server-set and signed, it can't be spoofed or tampered with from the browser.
