good, but missing basic feature for privacy and battery life

The feature where I can find what aisle a product is in at a particular store is really great, but theres no option to only use my location when the app is open, like most apps have. Its either always or never, so I end up choosing never to save battery and for privacy. How could they have missed this? Why wouldnt they just give the third option like other apps? I have to remember to turn off location tracking for the app every time after using it to find something in a store.
