Smartphone App Permissions Explained

Tap a permission to see what it means.

Location

Needed for location-based services like maps or delivery apps β€” can typically be set to "Always," "While Using," or similar granular options.

Camera

Needed for taking photos, scanning QR codes, or video calls.

Microphone

Needed for voice recording, voice calls, and voice search features.

Contacts

Requested so a messaging app can offer a "find friends" feature, or so a phone app can display caller information.

Photos/Media

Needed for an app to load or save photos and videos stored in your gallery.

Notifications

Allows an app to send you push notifications about news or messages.

Background Activity

Allows an app to keep syncing data or tracking location even when you're not actively using it.

Understand Before You Tap "Allow"

It's common to tap "Allow" on a permission prompt without much thought when installing or opening an app, but knowing what data each permission accesses lets you decline unnecessary ones and better protect your privacy.

Review Permissions Periodically

It's worth periodically reviewing which permissions your installed apps actually have, since an app you granted broad access to early on may not need all of it for how you actually use it today.

Frequently Asked Questions

Why would a calculator app ask for location access?

Apps that request permissions unrelated to their function are often doing so for advertising purposes or unnecessary data collection β€” it's a good idea to deny the permission or reconsider installing the app altogether.

Can I revoke a permission I already granted?

Yes β€” you can review and revoke individual app permissions anytime from your smartphone's app permission settings menu.
