MapIt on phone
MapIt app on Google Play Store requires access to camera to record images that will be used for creating the map. When saving, a database containing these images is created. That database is saved locally on the device (on the sd-card under MapIt folder). MapIt requires read/write access to MapIt folder only, to save, export and open maps. MapIt doesn’t access any other information outside the MapIt folder. MapIt doesn’t share information over Internet unless the user explicitly clicks on Share button.
