First-Party Pixel
One privacy-first pixel that connects visitors to real leads
A lightweight JavaScript SDK captures every pageview, form, and UTM parameter, then resolves anonymous sessions to known contacts — hashing email and phone in the browser before a single byte leaves the page.

Built for tracking and privacy at the same time
A vanilla-JS SDK that works on any HTML page, loads asynchronously, and never transmits raw personal data.
Client-side hashing
Email and phone are SHA256-hashed in the browser before any network call. Plain-text PII never leaves the page, and IP addresses are hashed server-side.
Identity resolution
Match anonymous visitor sessions to known contacts using hashed identifier interception and a persistent first-party cookie — no third-party cookies required.
Lightweight & async
A roughly 8 KB vanilla-JS SDK that loads asynchronously on any HTML page. Install one snippet and it captures pageviews, forms, UTMs, and session data uniformly.
First-party cookie
The _11metrics_uid cookie is scoped to your own domain. Tracking is first-party only and GDPR-conscious by design.
FAQ
Frequently asked.
Does the pixel store plain-text email or phone numbers?
No. Email and phone are SHA256-hashed client-side in the browser before any network request is made, so plain-text PII never leaves the page. IP addresses are hashed server-side. 11metrics stores zero plain-text personal identifiers.
Which websites can run the pixel?
The pixel is a vanilla JavaScript SDK (around 8 KB) that loads asynchronously and works on any HTML page, regardless of platform — Shopify, WooCommerce, or a custom storefront. You install one snippet and it tracks all campaigns uniformly.
How does it identify returning visitors without third-party cookies?
It uses a first-party cookie (_11metrics_uid) scoped to your own domain plus hashed identifier interception to resolve anonymous sessions to known contacts. No third-party cookies are involved.
