AffiliateAnthony I have two profiles. One with GSF and another one without. If I connect my Google account to my phone from the GSF profile, are there any privacy or security risk that I'll be facing on either or both profiles?
I think that question is insufficiently precise to have a clear answer.
If you were to access some web site from the two profiles from the same kind of device from the same IP address within the same minute, people could reasonably suspect it's the same person.

It's hard to say when there isn't any privacy risk. It is generally more productive to write down what you want to conceal from whom. Concealing everything from everybody while using an Internet-connected device (especially with a cellular connection) isn't really feasible.
