Resources
Whether you’re a WooCommerce store owner or a developer building custom sites, Lean GA4 Tracker gives you exactly what you need — nothing more, nothing less.
Privacy
This plugin does not collect, store, or transmit any personal data by itself.
It integrates your site with Google Analytics 4 (GA4) and/or Google Tag Manager (GTM).
Please review and configure your GA4 and GTM accounts in accordance with your local privacy laws (such as GDPR, CCPA).
Consent Mode
If enabled, Lean GA4 Tracker respects user tracking preferences via Google Consent Mode.
You can also integrate with third-party cookie banner plugins (Complianz, CookieYes, Cookiebot) to ensure visitor choices are honored.
WooCommerce Data
When WooCommerce tracking is enabled, the plugin sends product and order information to GA4, such as product name, category, brand, price, and quantity.
No personally identifiable information (PII) such as customer names or emails is collected or transmitted.
Recommended
We recommend that site owners:
– Update their site’s Privacy Policy to mention Google Analytics 4 and data sharing with Google
– Provide clear information to visitors about analytics tracking
– Use a consent management plugin to comply with GDPR/CCPA and other regulations
