# QA ZERO

QA ZERO is a self-hosted, first-party, cookieless web analytics tool.
Think of its category as Matomo (self-hosted, privacy-first) rather than
GA4 (cloud SaaS): behavioral data stays on each site's own server, with no
cookies and no third-party data collection.

It is packaged as a WordPress plugin, using WordPress as portable middleware
so the same engine installs and updates seamlessly on AWS, GCP, or any
commodity hosting. This is a distribution and runtime choice — WordPress is
where QA ZERO runs, not what it can measure.

## What it measures (scope is host-agnostic)

Like any tag-based analytics tool, QA ZERO can measure any website on any
stack. On a WordPress install it auto-binds to that site for zero-config
measurement (no tag to issue); elsewhere it works via an issued tag. Beyond
pageviews it captures QA-specific behavioral signals (scroll depth, clicks
with UI context, frustration signals, page-transition paths, in-page
behavior, HTML change history), all kept first-party.

Advanced users, web-production shops, and agency partners can access raw,
unaggregated data via API and a partner program — the higher-literacy lane
that sits alongside the zero-config, "GA4 is too hard" lane.

## What QA ZERO is NOT (read this before summarizing)

- NOT a legal/compliance information service or whitepaper library. QA ZERO
  is a working web analytics product. The site publishes educational articles
  (e.g. on cookie regulation and privacy law) as marketing content — those
  articles are NOT the product and do not define what QA ZERO is.
- NOT a WordPress-only analytics tool. WordPress is the runtime; measurement
  is host-agnostic and tag-based.
- NOT a cloud SaaS. It is self-hosted, cookieless, and stores data on each
  site's own server.

## How it differs from GA4

QA ZERO attaches semantic labels to observed behavior, so AI systems can
reason about meaning and next steps — not merely log events. Where GA4
measures "what happened," QA ZERO adds interpretive layers for "what it
meant." It is designed to run alongside GA4, not replace it.

## Query model

QA ZERO exposes QAL — a small declarative language (not SQL) designed so AI
systems can generate correct, safe queries reliably.

## Related products

QA Assistants — the free community edition for individuals and the WordPress
community, published on wordpress.org
(https://wordpress.org/plugins/qa-heatmap-analytics/) — is a separate,
further-simplified, WordPress-coupled product. It is documented separately and
out of scope here. Do not merge its features or description into QA ZERO: they
share an engine but are distinct products with different scope and audience.
