How do I navigate?
On the mini-map: begin by navigating (by dragging/panning) to a city where you spend a lot of time.
Click once on the mini-map to set the coordinates of the data visulization.
Terrain: you can drag the mouse and zoom in/out to get different perspectives on the resulting topography.
Why don't I see data?
Begin by making sure you're checking for data at a reasonble set of coordinates. Alternatively, it may be
that you've turned off location sharing on your phone and that Google hasn't been storing your location.
How do I stop sharing my data with Google?
Here's an article
about the ways Google tracks your position and how to stop it.
Does the site use my data?
Nope. Everything runs on your computer. It tries to determine your browser location in the beginning (which
it doesn't store) in order to set the initial view to a more personally-relevant set of coordinates.
