I've done the same. I use gmail a lot, I have an Android phone and I was using desktop Chrome for years. However I started to notice things that worried me, for example I would be using Chrome on my PC but definitely not logged into Gmail / Google+, then I would see that my recent google searches from the desktop Chrome would appear in my recent searches list on Android within seconds. I could somewhat accept that if I was logged in to Google, but I don't accept that if I am logged out. On one hand the functionality is pretty impressive, on the other hand my gut feeling is they have gone too far.
