Rules and Info
It is allowed to google.
Not sure you know the right answer? Read the hints closely, consider a telephone joker!
At any place that represents a valid clue, it is possible to get the next clue by pressing the "go" button. Even if you closed the app in between clues. If you're not at one of the clue-places the app will show the last clue and tell you that you're at the wrong place.
Make sure you agree on wether it is allowed to use reverse image search or not.
Phone Settings
You'll need to allow the browser on your phone to find your gps location in order for the app to know if you're at the right place. Therefore - depending on your current phone settings- you might need to change some settings. You can of course change them back after the treasure hunt. I, as architect of the app, can not track you or see where you are.
