Of course it will, and all your e-mails and all your personal and company documents. You should think of anything going through Google as "I am giving this to Google to profile me and extract ad targeting information." I bet they crawl the Google Cloud block and object storage volumes and extract information too, which means that all SaaS hosted at Google is probably mined by Google. That would be my expectation unless the contract contains very specific non-weasel-worded language prohibiting this. Any company that does ads or ad-tech as a significant part of their revenue is guilty of maximal privacy invasion unless proven innocent.
