The software license terms for Word and all the other desktop apps does not include such a clause, no. https://www.microsoft.com/en-us/useterms

The Microsoft Services Agreement applies to your use of their online services, like OneDrive and SharePoint, as you say, and there's an explicit consent in the app and a giant off switch there. They employ dark patterns to push you strongly to use their online services, but it's still optional.

It should be readily obvious that choosing to use online sharing or storage features or submit reviews require the data you enter to be sent, shared, or stored thusly...

In that case I stand corrected. Apparently you could use Word without accepting an agreement potentially granting Microsoft a license to what you write.

No offense, I'm aware of how complex laws can be, but... Shouldn't that be obvious? Or do you think you also grant a license to any pen manufacturer to help you write whatever it is that you are writing?

Word isnt a desktop app anymore. Its a service that is also made available via a desktop app. You cant just ignore 365 like that
