What Data Does Jetpack Sync?

To take advantage of the performance boosting features of Jetpack, certain information about the content, settings, and setup of your site are synced with our servers. This data begins to sync when Jetpack is installed and connected to a User ID.

We handle synced data under the terms of our Privacy Policy.

Content and Settings

In order to display accurate information about your site in places such as notification emails and the Reader, Jetpack syncs the following information:

  • Name
  • Tagline
  • Timezone

In order to allow the creation and management of content from different locations and devices (e.g. from the desktop or mobile apps), information about the following is also synced:

  • Posts
  • Pages
  • Custom Post Types
  • Related metadata

This index of your content helps reduce the load on your site’s servers, and also allows related content to be generated and displayed where appropriate.

Additional Data

We also sync the following data:

  • Comments and their metadata
  • Taxonomies (including categories and tags)
  • Custom taxonomies (if present)

This enables a number of features, including protecting your comments from spam (if using Akismet), displaying notifications, showing content in appropriate categories in the Reader, as well as adding the ability to edit your menus and post data from (including through the desktop and mobile apps).

  • The name of the theme or plugin in use
  • The theme or plugin’s version and capabilities (e.g. featured image, menu locations, and pending updates)
  • Plugin installation path
  • All whitelisted options, constants, and function outputs (e.g. whether the site is a multi-site install)

This enables Jetpack to provide services such as:

  • Remote plugin installation and management
  • Automatic plugin updates
  • Automatic theme updates (future)
  • Theme installation (future)
  • Theme customization from (including via the desktop or mobile apps)
  • Aggregated statistics and insights (future)

User-Related Data

Jetpack also syncs other miscellaneous items of user information, such as:

  • The usernames, email addresses, roles and capabilities (but not passwords) of registered users.
  • User ID of any users that make changes to the site, and the time that the change was made (e.g. ID of the user that added a new user, modified the site icon, or trashed a comment).

The user-related data is used by Jetpack for a variety of purposes. This includes:

  • Preventing unauthorized access.
  • Providing audit logs (future).
  • Managing followers (e-mail notification of subscribers).

WooCommerce Services

WooCommerce Services uses Automattic’s servers and a connection to our partners to enable useful features for your WooCommerce Store. Some of these features (such as those in WooCommerce Shipping) require data from your site to work.

Shipping Rates and Labels

To take advantage of the real-time shipping rates and shipping label features of WooCommerce Services, certain information about shopping carts, orders, and the setup of your site are passed to our partners via Automattic’s servers. In terms of data handling, we validate (but do not store) data you send to us, and then pass that data to our partners. On their end, our partners process the data under the terms of their agreements with Automattic and their own privacy policies. All data that flows between your site and Automattic, and between Automattic and our partners, is encrypted, end to end, via HTTPS.

Real-Time USPS and Canada Post Shipping Rates

In order to display shipping rates, WooCommerce Services sends the following information to our servers:

  • Shipping zone settings, for validation when you, the merchant, make changes and when fetching the rates for the customer, including origin postcode, list of enabled delivery services, and list of custom packages you, the merchant, add to the packaging manager.
  • Purchased products’ dimensions, weight, product IDs, and quantity.
  • Package destination address (street, postcode, city, country, state).

Additionally, once each day, WooCommerce Services asks our servers for any updates to the settings for each shipping service. This allows us to add new services and shipping options without you having to explicitly update. This data is not retained by us or our partners.

USPS Shipping Labels

To provide shipping labels, WooCommerce Services sends the following information from your site to our servers:

  • Merchant and customer names, addresses, and phone numbers.
  • Label packaging settings (dimensions and weight of the packages).
  • Your selected payment method.

To purchase shipping labels, you are required to have a payment method (credit card) saved on file with We keep a copy of each shipping label (both on our servers and on the servers of our shipping partners). This makes it easier for you to reprint labels and get help with support requests.

Usage Data Collection

To help improve WooCommerce Services, our server automatically logs each request from your site. Each request is tagged with a unique ID that your site randomly generates when WooCommerce Services is activated for the first time. This unique ID is an anonymous identifier, that does not map back to you. To protect your and your customers’ anonymity, we strip merchant and customer identifying details (the merchant name, street address, phone number, and customer name, street address, and phone number) from each request before it’s logged.

Additional Data

We also sync the following data with each request:

  • Shipping zone settings, for validation.
  • Fetching payment methods, as configured on
  • This enables a number of features, including showing appropriate shipping methods and making sure we return correctly translated text and units of measurement for your store.

Third Parties

You may choose to set up and/or use third party services, such as TaxJar for tax calculations. If you do so, you understand that some of your and your customers’ data may be passed to the respective third party, and the respective third party’s privacy policy will apply. 

TaxJar receives the value of goods in your cart, the value of shipping, your address, and the destination address.
