I don't think they could be too precise. It has a very poor map of the entire world, no legend to tell you what the different colors mean, and you cannot zoom closer to your location. There is no personal info requested other than your zip code, so I doubt they could find you. I was kind of disappointed that I couldn't tell how far away the other dots were from mine, or what they meant. I could only tell which parts of the world are more furry than other parts. That's about all I could find a use for.
