Privacy
Location information gathered by this application does not leave your device (as a matter of fact, this app doesn't use the Internet at all). The altitude and pressure history for the last 48 hours is stored in local app storage - this is used to determine weather forecasts. The last known location is also stored in app preferences to allow faster load times and support app functionality when the GPS can not be reached. The beacons and paths store their location information in a local SQLite database. All of this information is cleared when you clear the app storage or delete it.
