1. Open the Settings Tab and tap 'Privacy' to see the list of apps that have requested access to your location data.

2. Tap on the 'Location Services' tab.

3. The next screen will show the list of apps that can request access to your location information. You may also check if you have granted access and if these apps can access your location at all times or only when you're using it. To know more information about location settings of a specific app, you may tap it.

There are three different options:

Never: The app will never be allowed to access your location information.

When Using the App: The app will be allowed to access your data as long as it is open and active.

Always: This option allows the app to access your data whenever it needs it.
