Does SwiftKey sell content we type using their keyboard to advertisers?

Perhaps this is a coincidence, but it appears that topics in private messages I am sending are appearing in advertisements shown to me in other apps.

Does SwiftKey sell content we type using their keyboard to advertisers?

For example, I typed an iMessage about an Omega watch and later that same week I started seeing lots of ads for Omega watches in the Wall Street Journal iPhone app.  I have not searched for Omega watches in any search engine, just typed about them in a private iMessage.

When I click on the SwiftKey Privacy Policy it goes to a generic Microsoft page that says Microsoft does sell data to advertisers.  Please let me know how my private data is being used.  Does this Microsoft policy of selling user data to advertisers include my SwiftKey account data?  Is everything that I am typing being compiled and sold to advertisers so that they can show me relevant ads when I read the Wall Street Journal?

Thank you.
