On the surface, Android and privacy might not seem like the most natural of bedfellows. Google is known for its advertising business, after all — it's how the company makes the lion's share of its money — and it can be tough to square the notion of data collection with the concept of carefully controlled information.
In actuality, though, Google gives you a good amount of authority over how and when it taps into your Android-associated info. (And even at its worst, the company never shares your data with anyone or sells it to third parties, despite some broad misconceptions to the contrary.) Ultimately, it just comes down to a matter of educating yourself about the possibilities and then determining what balance of privacy and function makes the most sense for you.
