Do you think none of your data makes it to Google in any form if you aren't logged in? Like, say, use of maps and web browsing? Association between the data and you is easy. As long as you've ever logged in to Google on a desktop (or any device for that matter), and another third party non-Google account on the same device, the moment you log into that third-party (non-Google) account on the phone, your identity could be tied to the data by Google if Google has a data sharing partnership that enables that with the third party. Even if you refrain from logging in to a Google account on the phone.
