Trackless measures your site’s traffic — and, on WooCommerce stores, your real revenue and margin — entirely server-side. No cookies, no JavaScript snippet, no consent banner slowing your pages down. You read the reports in your Trackless account dashboard.
How visitors are counted (privacy by design):
<ul>
<li>The visitor key is a daily-rotating HMAC-SHA256 hash of IP + User-Agent + day, keyed with a secret salt that exists only on your server. It cannot be reversed and changes every day.</li>
<li>The raw IP address is never stored and never transmitted — only a keyed hash.</li>
<li>Global Privacy Control (the <code>Sec-GPC</code> browser signal) is honoured: opted-out visitors are not tracked at all.</li>
<li>No data is written to the visitor’s browser — no cookies, no localStorage, no fingerprinting scripts.</li>
</ul>
What it measures:
<ul>
<li>Visits and sessions with source / medium / campaign and a GA4-style channel group</li>
<li>Page views and events: product view, category view, search, add to cart, cart, checkout, 404</li>
<li>Device, browser, OS, country and language (one row per visitor per day)</li>
<li>With WooCommerce: orders, revenue, refunds, payment and shipping methods, first-order flag, order attribution (WooCommerce 8.5+ Order Attribution), ordered items — including per-unit purchase cost for margin reporting if you store it (<code>_wc_cog_cost</code>, <code>_alg_wc_cog_cost</code>, <code>_cost</code> or the <code>trackless_wholesale_price</code> filter)</li>
</ul>
Events are collected into a small queue table in your own database and flushed once a day via WP-Cron (or manually with the “Send now” button). The delivery is HMAC-SHA256 signed and idempotent, so retries are safe.
WooCommerce is optional: on a plain WordPress site you get cookieless web analytics; with WooCommerce you also get the e-commerce metrics.
<h4>External service: Trackless (please read)</h4>
This plugin is a connector for Trackless (https://trackless.cz), a hosted analytics service. It is not a standalone statistics plugin — the reports live in your Trackless account, and the plugin sends data to the service’s ingest endpoint at <code>https://trackless.cz/ingest</code>.
When data is sent: only after you enter your API key and explicitly tick the Data Processing Agreement (DPA) consent checkbox in the plugin settings. Until you do both, the plugin collects and sends nothing.
What is sent (once a day, HMAC-signed):
<ul>
<li>Anonymous traffic aggregates: hashed visitor identifiers (keyed HMAC, daily-rotating), hashed IPs, page URLs, referrers, UTM parameters and click IDs, the raw User-Agent (used server-side to derive device/browser/OS and to flag bots — not stored), country code, language</li>
<li>With WooCommerce: order data including order ID, totals and refunds (amounts), currency, payment method, shipping method, order status, attribution, and line items with prices and (if configured) per-unit purchase costs</li>
<li>Site metadata: site name, domain, timezone, currency, order statuses, product categories, carriers, payment gateway names</li>
</ul>
IP→country database: to show visitor country on hosting without a geo header (no Cloudflare / GeoIP module), the plugin downloads a small public IP→country database from <code>https://trackless.cz/api/geoip/country.dat.gz</code> (refreshed about once a week) and resolves the country locally — the visitor IP never leaves your server for this. The database is DB-IP Lite by DB-IP (https://db-ip.com), licensed CC BY 4.0.
Terms and pricing: Trackless is a paid service with a 30-day free trial; you need a Trackless account and API key to use this plugin.

Stefan Klaes

Simplest Analytics tracks visits and unique users session based serverside without setting 3rd party cookies. It is also possible to track events and url paramaters. After 
installing and activation the plugin it’s working without further configuration. If you want to set up custom tracking events or url parameters you can use the settings tab in 
the WordPress backend.
<h4>Why use Simplest Analytics?</h4>
It is working. No function overload. Track visits, unique users and custom events like clicks.
<h4>What are the main features of the plugin?</h4>
<ul>
<li>Track page visits and unique users</li>
<li>Track traffic on sites</li>
<li>Track where your traffic comes from</li>
<li>Track where your woocommerce sales come from</li>
<li>Track custom events when a user clicks an element</li>
<li>Track the use of url parameters like your-site.com/?campaign=whatever</li>
<li>Track video views (1sec, 25%, 50%, 75%, 100%)</li>
</ul>
<h3>Custom function you can use to track further events</h3>
You can use this function to track further events in php hooks like form submissions, apply coupons, add to cart, etc:
$data = []; 
$data[‘track_type’] = “event”; // event or pageview 
$data[‘event_action’] = “yourevent”; // name of the event 
simple_analytics_track_data($data); // function that saves the event
<h4>How are the charts in the admin dashboard generated?</h4>
The charts are based on google-charts.js which only load in the admin backend. The data is stored in the database on the same server where your WordPress installation 
is located.

Simplest Analytics

Simple webanalytics stored in the own database without setting cookies.
