Who can see me on the map?

You can change your visibility on the map by pressing the button on the top-right of the map screen:

Green: Available. Everyone can see you, and your general location is occasionally updated as you move and go about your day. You will receive notifications of new banknotes when they're posted in your area.

Red: Unavailable. No one can see you, and your location is private. 

Blue: Private Mode. Everyone can see you, and your general location is occasionally updated as you move around and go about your day. You will not receive notifications of new banknotes posted in your area, however you are still available to receive Private Offers.
