Data Used: If Akismet is enabled on the site, the contact form submission data — IP address, user agent, name, email address, website, and message — is submitted to the Akismet service (also owned by Automattic) for the sole purpose of spam checking. The actual submission data is stored in the database of the site on which it was submitted and is emailed directly to the owner of the form (i.e. the site author who published the page on which the contact form resides). This email will include the submitter’s IP address, timestamp, name, email address, website, and message.
Data Synced (?): Post and post meta data associated with a user’s contact form submission. If Akismet is enabled on the site, the IP address and user agent originally submitted with the comment are synced, as well, as they are stored in post meta.
Data Used: Please refer to the appropriate Google Analytics documentation for the specific type of data it collects. For sites running WooCommerce (also owned by Automattic) and this feature simultaneously and having all purchase tracking explicitly enabled, purchase events will send Google Analytics the following information: order number, product id and name, product category, total cost, and quantity of items purchased. Google Analytics does offer IP anonymization, which can be enabled by the site owner.
Activity Tracked: This feature sends page view events (and potentially video play events) over to Google Analytics for consumption. For sites running WooCommerce-powered stores, some additional events are also sent to Google Analytics: shopping cart additions and removals, product listing views and clicks, product detail views, and purchases. Tracking for each specific WooCommerce event needs to be enabled by the site owner.
