How to Check App Permissions on Your Phone

Review what data and features each app can access on your iPhone or Android phone.

Steps

1
Open your phone Settings
and find the Apps or Applications section. This lists every app installed on your device.
2
Select an app to see what permissions it has.
Each app lists the features it can use like camera, microphone, contacts, and location.
3
Turn off permissions the app does not need.
A calculator app does not need access to your contacts or microphone.
4
Review location permissions specifically.
Set location access to "While Using the App" instead of "Always" for most apps.
5
Check new apps before granting permissions.
When an app asks for permission, read the request and deny it if the access does not match the app purpose.

What is the most dangerous app permission?Show

Camera and microphone permissions are the most sensitive. Only grant these to apps that need them for their core function.

Can I change app permissions later?Show

Yes, you can change app permissions at any time through your phone Settings. Changes take effect immediately.

Do iPhone and Android handle permissions the same way?Show

Both let you control permissions per app. Android gives more detailed controls. iPhone requires apps to ask each time for sensitive permissions.
