Activity Log
This feature only records activities of a site’s registered users, and the retention duration of activity data will depend on the site’s plan and activity type.

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.

Google Analytics

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.

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.

Notifications
This feature is only accessible to registered users of the site who are 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.

Simple Payments

Data Used: Transaction amount, transaction currency code, product title, product price, product ID, order quantity, PayPal payer ID, and PayPal transaction ID.

Activity Tracked: The PayPal payer ID, transaction ID, and HTTP referrer are sent with a payment completion tracking event that is attached to the site owner.

Data Synced: PayPal transaction ID, PayPal transaction status, PayPal product ID, quantity, price, customer email address, currency, and payment button CTA text.

Because payments are processed by PayPal, we recommend reviewing its privacy policy.

Subscriptions
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.

WordPress.com Secure Sign On
This feature is only accessible to registered users of the site with WordPress.com accounts.

Data Used: User ID (local site and WordPress.com), role (e.g. administrator), email address, username and display name. Additionally, for activity tracking (see below): 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.

Activity Tracked: The following usage events are recorded: starting the login process, completing the login process, failing the login process, successfully being redirected after login, and failing to be redirected after login. Several functionality cookies are also set, and these are detailed explicitly in our Cookie documentation.

Data Synced: The user ID and role of any user who successfully signed in via this feature.

WordPress.com Stats
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.

Activity Tracked: Post and page views, video plays (if videos are hosted by WordPress.com), outbound link clicks, referring URLs and search engine terms, and country. When this module is enabled, Jetpack also tracks performance on each page load that includes the Javascript file used for tracking stats. This is exclusively for aggregate performance tracking across Jetpack sites in order to make sure that our plugin and code is not causing performance issues. This includes the tracking of page load times and resource loading duration (image files, Javascript files, CSS files, etc.). The site owner has the ability to force this feature to honor DNT settings of visitors. By default, DNT is currently not honored.
