ChangeTrace watches your WordPress and WooCommerce site for meaningful changes and
errors and sends them to the ChangeTrace service (a cloud dashboard at
https://app.change-trace.com), where they are correlated against metrics to surface
the most likely cause of a movement, with evidence.

This plugin is the on-site agent. It does nothing until you connect it: you paste a
site token generated in the ChangeTrace dashboard, and only then does the plugin begin
sending data to the ChangeTrace API.

What it collects (once connected):

A one-time baseline snapshot on connect: your active plugins and theme and their
versions, plus WordPress, PHP, and WooCommerce versions.
An hourly heartbeat so the dashboard knows the site is alive.
Change detection — when plugins/theme/versions change.
Error capture — PHP fatals/errors (shutdown + error handler, fails silently),
frontend JS errors (window.onerror, unhandled rejections, failed/5xx fetch & XHR;
sampled), and 5xx/timeouts on WordPress’s outbound HTTP and its own REST API.

All error payloads are PII-stripped (emails, credentials, form values, card numbers)
and size-capped before they are queued and sent. Events are held in a bounded local queue
and sent in batches (roughly every 5 minutes) with retry/backoff.

A ChangeTrace account is required. ChangeTrace is a third-party SaaS. See the
“External services” section below for exactly what is sent and where.

External services

This plugin connects to the ChangeTrace service to send monitoring data. This connection
is required for the plugin to do anything, and only starts after you connect the plugin
with a site token from the ChangeTrace dashboard.

Services used

ChangeTrace API — https://api.change-trace.com
ChangeTrace dashboard (web app) — https://app.change-trace.com

What data is sent, and when

On connect (once): a baseline snapshot — your active plugins and theme with versions,
and your WordPress, PHP, and WooCommerce versions.
Every hour: a heartbeat (site is alive) plus your site token in the request header.
Roughly every 5 minutes (when there is activity): a batch of events — detected changes
and captured errors (PHP/JS/HTTP). Error payloads are PII-stripped and size-capped.
On connect, your browser is sent to https://app.change-trace.com to sign in and approve
connecting this site.

Your site token is stored on your site and only ever sent to the API as an Authorization
header; the API stores only a hash of it. No data is sent before you connect.
