Activity Log
Data Used: To deliver this functionality and record activities around site management, the following information is captured: user email address, user role, user login, user display name, WordPress.com and local user IDs, the activity to be recorded, the WordPress.com-connected site ID of the site on which the activity takes place, the site’s Jetpack version, and the timestamp of the activity. Some activities may also include the actor’s IP address (login attempts, for example) and user agent.
Activity Tracked: Login attempts/actions, post and page update and publish actions, comment/pingback submission and management actions, plugin and theme management actions, widget updates, user management actions, and the modification of other various site settings and options. Retention duration of activity data depends on the site’s plan and activity type. See the complete list of currently-recorded activities (along with retention information).

Log data (IP address, geographical data, user agent, operating system, device type) is stored for 30 days. The unique user ID is stored in cookies and is retained for 1 year.
Activity Tracked: Ad impressions, video-related events (i.e. pause, mute, 100% plays, etc.) or errors, and ad click events.

Comment Likes
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.

Contact Form
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.
Gravatar Hovercards
Data Used: This feature will send a hash of the user’s email address (if logged in to the site or WordPress.com — or if they submitted a comment on the site using their email address that is attached to an active Gravatar profile) to the Gravatar service (also owned by Automattic) in order to retrieve their profile image.
Infinite Scroll
Data Used: In order to record page views via WordPress.com Stats (which must be enabled for page view tracking here to work) with additional loads, the following information is 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.
Activity Tracked: Page views will be tracked with each additional load (i.e. when you scroll down to the bottom of the page and a new set of posts loads automatically). If the site owner has enabled Google Analytics to work with this feature, a page view event will also be sent to the appropriate Google Analytics account with each additional load.
Likes
Data Used: In order to process a post like action, the following information is used: IP address, WordPress.com user ID, WordPress.com username, WordPress.com-connected site ID (on which the post was liked), post ID (of the post that was liked), user agent, 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.
Search
Data Used: Any of the visitor-chosen search filters and query data in order to process a search request on the WordPress.com servers.
Sharing

This content will be sent to Akismet (also owned by Automattic) so that a spam check can be performed. Additionally, if reCAPTCHA (by Google) is enabled by the site owner, the sharing party’s IP address will be shared with that service. You can find Google’s privacy policy here.
