Some apps need to know when you’re in a specific location to work correctly. For instance, if you’ve asked an app to remind you to buy bread when you’re in the grocery store, the app will need to know when you’re in the store. To give you maps to get you where you’re going, or give you a lists of shops or restaurants near you, many apps and services request location information from your device. That’s what the Windows 10 location service does: tells your apps and services where you are or where you’ve been, so that you can get info more relevant to you.
When we collect data, we want to make sure it’s the right choice for you. That’s why we provide info about the location service and settings described here.
The first time an app that uses the Windows location service needs your device location or location history, it requests your permission. If you give an app permission but you change your mind later, you can turn off that app’s access to your device location in Settings > Privacy > Location .
Some Windows apps and services that use location info also use your location history. When the location setting is on, locations looked up by apps or services will be stored on the device for a limited time (24 hours in Windows 10), then deleted. Apps that have access to this info will be labeled Uses location history on the location settings page.
To help provide you with more useful services, apps that are not allowed to use location services may still use your general location, such as city, zip code, or region. But if you prefer, you can turn this off for all apps in location settings.
You can set a default location for your PC that Windows, apps, and services can then use when a more exact location can’t be detected using GPS or other methods.
Some apps use geofencing, which can turn on or off particular services or show you information that might be useful when you’re in an area defined (or “fenced”) by the app. An app can only use geofencing if location has been turned on for that app. If any of your Windows apps are using geofencing, you’ll see One or more of your apps are currently using geofencing on the location settings page.
Cortana works best when she has access to your device location and location history, which she uses to help you—for example, by giving you traffic alerts before you need to leave or reminders based on location like “You’re near the grocery store, where you wanted to buy milk.” Cortana collects your location periodically even if you’re not interacting with her, like when you connect to Wi Fi or disconnect from Bluetooth. When Cortana is turned on, the Search app also has access to your device location information and will automatically send it to Bing when Cortana suggests web search terms and results for Bing to use as described in the privacy statement. If you don’t want Cortana to have access to your device location, you need to turn off Cortana completely:
When location is turned on for Microsoft Edge, you still have control over which websites can access your device location. Microsoft Edge will ask for your permission the first time you visit a website that requests your location information. You can turn off location permission for a website in Microsoft Edge settings.
The Windows location service won’t drain your battery. In fact, keeping the screen on while you follow directions to drive somewhere uses a lot more power than the location service does.
Even when you’ve turned off the Windows location service for your device or user account, some apps and services may use technologies like Bluetooth and Wi-Fi scanning to find out your device’s location. In most cases, this occurs only in apps and services that either come with Windows or are available in the Store.
Classic Windows applications won’t ask for permission to discover your device location information and won’t appear in your Choose apps that can use your location list. What are Classic Windows applications? They’re programs that use Windows Platform components such as .NET, COM, Win32, and others. They are typically desktop apps (which run on your device) rather than web-based apps (which run in the cloud). You’d usually install one by downloading it from the Internet or with some type of media (such as a CD, DVD, or USB), and sometimes from the Windows Store. Classic Windows apps launch by using an .EXE or .DLL file.
So that you can find lost devices, stay connected to the Internet, and get help in an emergency, Microsoft services like Find My Device, Wi-Fi Sense, and Wi-Fi calling (for example, when used to call 911) will still have access to your device’s location if these services are turned on for your device. In addition, your mobile operator will have access to your device’s location if your device has a SIM card or is using a cellular service. Please read the privacy policies of app publishers and mobile operators to learn more about how those apps and services use your device’s location.
To help us provide location services, Microsoft records the location of mobile cell towers and Wi-Fi access points. Our database might include the MAC addresses of your wireless router or other Wi-Fi network devices. We don’t associate MAC addresses with you personally or with the devices connected to your network.
To prevent Microsoft from using the MAC addresses of your Wi-Fi access points in our location services database, go to Opt out of location services.
When one or more apps are currently using your device location through the Windows location service, you’ll see the location icon in the notification area of your taskbar (on Windows 10 PCs) or in the status bar at the top of your screen (on Windows 10 Mobile devices). The icon won’t be shown for geofencing.
If you’re using a device assigned to you by your workplace, or if you’re using a personal device at your workplace, you might not be able to change the location settings. If that’s the case, Some settings are managed by your organization will appear at the top of the location settings page.
Windows location settings give you control over which Windows apps can use your device location and location history information. To check your location settings, go to Settings > Privacy > Location .
To clear location history, either reboot your device, or go to Settings > Privacy > Location and select Clear. Clearing the location history only clears the history on the device. Apps that accessed the history before it was cleared may have stored it elsewhere. Refer to your apps’ privacy policies for more info.
To clear location history that’s been stored in the cloud and is associated with your Microsoft account, go to account.microsoft.com, and make sure you’re signed in to your account. Select Clear location activity, and then select Clear.
