Private Location Tracker allows you to track all your locations throughout your days and back them up to Dropbox. Dropbox backups are encrypted on your device with a 256-bit key that only you know so not even Dropbox can access your locations. Locations can be filtered based on date, streets, cities, and countries and exported as CSV, JSON and KML files. Backed up locations can be shared and accessed from the browser with your authentication code and encryption key.
