About privacy and Location Services on iOS, iPadOS and watchOS

Find out how privacy settings and Location Services help protect your personal information on your iPhone, iPad, iPod touch and Apple Watch.

Privacy settings

Privacy settings in iOS and iPadOS help give you control over which apps have access to information stored on your device. For example, you can allow a social network app to use your camera, so you can take and upload pictures to that app. You can also grant access to your contacts, so a messaging app can find any friends who are already using the same app.

In Settings > Privacy & Security, you can see which apps you have granted permission to access certain information, as well as having the option to grant or revoke any future access. This may include access to:

On your device, you can select a type of data from this list to see which apps have asked for permission to use that data. An app won't appear on the list until it has asked for permission to use your data. You can add or remove permission from any app that has asked for access to data. An app can only use the data type in the setting if you have given the app permission.

If you sign in to iCloud, apps are granted access to iCloud Drive by default. You can also view and manage apps that are allowed to use iCloud under iCloud in Settings.

If you allow third-party apps or websites to use your data or your current location, you're subject to their terms, privacy policies and practices. You should review the terms, privacy policies and practices of the apps and websites to understand how they use your location and other information. Information that Apple collects will be treated in accordance with Apple’s Privacy Policy.

How your device uses Location Services

With your permission, Location Services allows apps and websites (including Maps, Camera, Weather and other apps) to use information from mobile data¹, Wi-Fi², Global Positioning System (GPS)³ networks and Bluetooth⁴ to determine your location⁵.

Apps that can show your location on the screen, including Maps, show your current location using a blue marker. In Maps, if your location can’t be determined precisely, you’ll see a blue circle around the marker. The size of the circle shows how precisely your location can be determined – the smaller the circle, the greater the precision. When Location Services is active for an app, a black or white arrow icon appears in the status bar or in Control Centre.

Maps, directions and location-based apps depend on data services. These data services are subject to change and may not be available in all geographic areas, resulting in maps, directions or location-based information that may be unavailable, inaccurate or incomplete. Compare the information provided on the device with your surroundings and defer to signposts to resolve any discrepancies.

Give apps permission to use your location

The first time an app tries to access your location using Location Services, it must ask for your permission. A prompt will appear explaining which app is asking for permission to use your location, as well as the app developer's reason for requesting it.

Some apps ask to use your location only while the app is in use. An app is considered "in use" when you're actively using it in the foreground, or when it is using location in the background (in which case a blue pill will display in your status bar).

If you grant an app While In Use permission, the app may ask you for permission to use your location when it is in the background.

When you allow an app to use your location in the background, your device will remind you from time to time that an app is using your location, and will display those locations on a map. You'll also be asked if you want to continue to allow the app to use your location in the background.

With iOS 13 or later, iPadOS 13 or later and watchOS 6 or later, you can tap Allow Once to let an app access Location Services data only for one session (One Time). If you close and then re-open the app and it tries to access your location again, it will ask for your permission again. Apps won't use your location until they've asked for your permission and you've granted it.

You can change your mind at any time and update your preferences from Settings > Privacy & Security > Location Services.

Turn Location Services on or off

You can turn Location Services on or off in Settings > Privacy & Security > Location Services. You can turn Location Services on either during the Setup Assistant process or later through the Location Services setting. You can control which apps and system services have access to Location Services data individually. When Location Services are off, apps can't use your location from Location Services in the foreground or background. This will limit the performance of various Apple and third-party apps.

If you would like to reset all of your location settings to the factory default, go to Settings > General > Transfer or Reset [device], tap Reset, then tap Reset Location & Privacy. When your location and privacy settings are reset, apps will stop using your Location Services information until you grant them permission.

Improve GPS accuracy

GPS accuracy depends on the number of visible GPS satellites. Locating all visible satellites can take several minutes, with accuracy gradually increasing over time. To improve GPS accuracy:

• Make sure you've set the date, time and time zone correctly on the device in Settings > General > Date & Time. If possible, use Set Automatically.

• Keep a clear view in several directions. Walls, vehicle roofs, tall buildings, mountains and other obstructions can block line of sight to GPS satellites. When this happens, your device uses Wi-Fi or mobile networks to determine your position until the GPS satellites are visible again.

Crowd-sourced Wi-Fi and mobile Location Services

If Location Services is on, your device will periodically send the geo-tagged locations of nearby Wi-Fi hotspots and cell towers to Apple to augment Apple's crowd-sourced database of Wi-Fi hotspot and cell tower locations. While you're in transit (for example, driving or walking) and Location Services is on, a GPS-enabled iPhone or iPad will also periodically send GPS locations, travel speed and direction, and barometric pressure information to Apple to be used for building up Apple's crowd-sourced road traffic, roadway, pedestrian walkway and atmospheric correction databases. The crowd-sourced location data gathered by Apple is stored with encryption and doesn’t personally identify you.

About Bluetooth, data and Location Services

With iOS 13 or later and iPadOS 13 or later, an app must ask for permission to use Bluetooth functions except to play audio to a Bluetooth device, which doesn’t require permission. You can change your device’s Bluetooth permissions from Settings > Privacy & Security > Bluetooth.

About your location during emergency calls

For safety purposes, location information on your iPhone may be used when you place an emergency call to aid response efforts regardless of whether you’ve enabled Location Services.
