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).
Data Synced (?): Successful and failed login attempts, which will include the actor’s IP address and user agent.
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.
Jetpack Comments
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.
Mobile Theme
Data Used: A visitor’s preference on viewing the mobile version of a site.
Activity Tracked: A cookie (akm_mobile) is stored for 3.5 days to remember whether or not a visitor of the site wishes to view its mobile version. Learn more about this cookie.
Protect
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.
