My company helps provide aid to individuals in very life-threatening situations in other countries. Their personal identities and whereabouts are closely guarded for their safety. Each person is a record in our base. We would like to map out individuals by city in the Map App in order to help with basic logistical planning. My only question is:

Does using the Map App (Google Geocoding API) enable Google access to any information in the Base/Table/View outside of the 2 columns (location-text column and Geocoding Cache column) required to set the Map App up???

Thanks for any insight into possible security issues implementing the Map App!
