Attorney General Kamala D. Harris Issues Consumer Alert on Location Services Used by Mobile Apps
SAN FRANCISCO – California Attorney General Kamala D. Harris today issued a consumer alert on location services used by mobile applications (apps).
With a tap on your smartphone or tablet, you can get a list of nearby restaurants, directions to a friend’s home or a local weather forecast. Location services on your device make a variety of convenient apps work. Location services take your geographic information from satellites (GPS), WiFi and cell-tower networks. What you may not realize is that some apps can access your location all the time, even when you’re not using them. Your location might be “always on.”
Broadcasting your location can sometimes expose you and your family to risk of theft or physical harm. For instance, you may be unknowingly revealing your location if your phone is “geo-tagging” your photos. When you take a photo, the location where it was taken may be inserted into the image file, along with the date/time stamp. If you post the photo online, you are revealing your location at a point in time. Sharing a “selfie” without disabling geo-tagging can be dangerous, especially for victims of stalking or domestic abuse.
How mobile location services work may be technical, but you do not have to be an engineer to have more control. By adjusting the settings on your mobile device, you can control location services to protect your privacy on today’s “always on” frontier.
Android Phones and Devices
- Go to Settings, then Location and uncheck the boxes. When an app asks for access to your location, you can chose to grant it or not.
- To disable geo-tagging of photos, open the camera and then click on the gear icon and set location to “No.” You may have to click the gear icon on several screen layers.
- You can also choose how accurate you want your location reporting to be, whether it is determined based on GPS plus WiFi and cellular networks or just one or the other. The higher degree of accuracy uses more of your battery, so protecting your privacy will protect your battery life too.
iPhones and iPads (iOS 6 and later)
- Go to Settings, then Privacy, then Location Services. You can turn it off. Or you can choose which functions and apps to give access to your location.
- To disable geo-tagging of photos, deny location access to the camera, in Location Services.
- You may get notifications from apps asking to use your location in the background. For privacy, select “Don’t Allow.”
