You mistakenly assume this feature which by default requests your google login for sync will be understood by users as this, when they open their browser and see "Log into google". Much more likely is that your casual user will think they're logging into Gmail.

The vast majority of "spyware" and "malware" these days has a big long page of EULA legalise that makes the tracking totally optional too.

People clicking the "I agree" button on a EULA is not consent.
