Why do you need location data?

Except for one optional feature (noted below), the Dropbox app does not use your device's location data. However, because your photos may contain information about where they were taken, Dropbox (like other apps) needs special permission to access them.

Apple's privacy settings for photos are separate from location services, so the app will simply ask for permission to access your photos. In either case, the app will not be able to upload photos to your Dropbox unless you give the OK.

Background uploading

If you turn on the background uploading option in the Camera Upload settings, the app will ask for permission to access your device's location services. This will enable the app to finish large uploads without the need for you to open the app.

Here's how it works: Normally, photos and videos can upload while the Dropbox app is open and for only a few minutes after it is closed. But with background uploading turned on, the app will automatically resume unfinished uploads when it detects a significant change in your device's location. This feature is designed to make the Camera Upload feature work more efficiently and does not collect your location information.

When the background uploading option is set to On, you'll see the location services arrow appear at the top of the screen:

This icon usually means that an app (such as a mapping app) is using your device's GPS system (if applicable) to keep track of your precise location—and eating up a lot of battery in the process. However, Dropbox's background uploading feature uses a low-power version of Apple's location services. If you have a big backlog of photos to upload, you may notice that the app uses some power. But once that's done, uploading new photos should have little effect on battery life.
