Since I have a Mac and an Android phone, I'm not sure what to do for cross-platform sync. If I pick Chrome, I don't have to download any new browser on my Android device. However, I also need privacy.
In all honesty (and I don't mean to sound harsh) but it probably doesn't matter what you use, with your mac, simply because you're using android, and Google's business model is to collect user data and sell it. You using android already means that any action you take on your mac is immaterial because google is already collecting it off your phone
