Is MyRegistry Ship Address Assist safe?

Low risk

MyRegistry Ship Address Assist renders saved shipping address details into the DOM on visited non-MyRegistry pages.

When its widget is visible, the extension reads the recipient name and address from browser sync storage after page load and injects them into a page DOM widget on all non-MyRegistry sites. Scripts running on those pages can read the widget fields, including name, street address, city, state, ZIP, country code, and owner label.
