Below are detailed the data I share with Jetpack and how they are used.
This feature is only accessible to users logged in to WordPress.com.
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.
Activity Tracked: Post likes.
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.
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 (
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: 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.
