Data Used: In order to process a comment like, the following information is used: WordPress.com user ID/username (you must be logged in to use this feature), the local site-specific user ID (if the user is signed in to the site on which the like occurred), and a true/false data point that tells us if the user liked a specific comment. If you perform a like action from one of our mobile apps, some additional information is used to track the activity: IP address, user agent, timestamp of event, blog ID, browser language, country code, and device info.

This feature is only available to sites on the Premium and Professional plans.
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.
Data Used: Commenter’s name, email address, and site URL (if provided via the comment form), timestamp, and IP address. Additionally, a jetpack.wordpress.com IFrame receives the following data: WordPress.com blog ID attached to the site, ID of the post on which the comment is being submitted, commenter’s local user ID (if available), commenter’s local username (if available), commenter’s site URL (if available), MD5 hash of the commenter’s email address (if available), and the comment content. If Akismet (also owned by Automattic) is enabled on the site, the following information is sent to the service for the sole purpose of spam checking: commenter’s name, email address, site URL, IP address, and user agent.
Activity Tracked: The comment author’s name, email address, and site URL (if provided during the comment submission) are stored in cookies. Learn more about these cookies.
Data Synced (?): All data and metadata (see above) associated with comments. This includes the status of the comment and, if Akismet is enabled on the site, whether or not it was classified as spam by Akismet.
This feature is only accessible to users logged in to WordPress.com.

Data Used: IP address, WordPress.com user ID, WordPress.com username, WordPress.com-connected site ID and URL, Jetpack version, user agent, visiting URL, referring URL, timestamp of event, browser language, country code. Some visitor-related information or activity may be sent to the site owner via this feature. This may include: email address, WordPress.com username, site URL, email address, comment content, follow actions, etc.
Activity Tracked: Sending notifications (i.e. when we send a notification to a particular user), opening notifications (i.e. when a user opens a notification that they receive), performing an action from within the notification panel (e.g. liking a comment or marking a comment as spam), and clicking on any link from within the notification panel/interface.
Data Used: In order to check login activity and potentially block fraudulent attempts, the following information is used: attempting user’s IP address, attempting user’s email address/username (i.e. according to the value they were attempting to use during the login process), and all IP-related HTTP headers attached to the attempting user.
Activity Tracked: Failed login attempts (these include IP address and user agent). We also set a cookie (jpp_math_pass) for 1 day to remember if/when a user has successfully completed a math captcha to prove that they’re a real human. Learn more about this cookie.
Data Synced (?): Failed login attempts, which contain the user’s IP address, attempted username or email address, and user agent information.
Data Used: To initiate and process subscriptions, the following information is used: subscriber’s email address and the ID of the post or comment (depending on the specific subscription being processed). In the event of a new subscription being initiated, we also collect some basic server data, including all of the subscribing user’s HTTP request headers, the IP address from which the subscribing user is viewing the page, and the URI which was given in order to access the page (REQUEST_URI and DOCUMENT_URI). This server data used for the exclusive purpose of monitoring and preventing abuse and spam.
Activity Tracked: Functionality cookies are set for a duration of 347 days to remember a visitor’s blog and post subscription choices if, in fact, they have an active subscription.
Data Used: For video play tracking via WordPress.com Stats, the following information is used: viewer’s IP address, WordPress.com user ID (if logged in), WordPress.com username (if logged in), user agent, visiting URL, referring URL, timestamp of event, browser language, country code. If Google Analytics is enabled, video play events will be sent there, as well.

Data Used: IP address, WordPress.com user ID (if logged in), WordPress.com username (if logged in), user agent, visiting URL, referring URL, timestamp of event, browser language, country code. Important: The site owner does not have access to any of this information via this feature. For example, a site owner can see that a specific post has 285 views, but he/she cannot see which specific users/accounts viewed that post. Stats logs — containing visitor IP addresses and WordPress.com usernames (if available) — are retained by Automattic for 28 days and are used for the sole purpose of powering this feature.
