Is Smart SEO safe?

Low risk

Smart SEO sends the active tab's hostname with a persistent extension-generated user ID to Semalt.

When you open Smart SEO from the toolbar, it reads the current tab's URL, reduces it to the hostname, and pairs it with a user ID stored in extension local storage. It posts that site name and identifier to Semalt's site-analyze logging endpoint.
