Where to find app permissions and change them
App permissions on iPhone live in Settings, not inside the apps themselves. Open Settings, scroll down to find the app name, tap it, and you will see a list of permissions that app has asked for — things like Camera, Microphone, Photos, Location, Contacts, and Calendar. Each permission shows a status: Allow, Don't Allow, or Ask Next Time. Tap any permission to change it.
The fastest route is Settings > Privacy & Security, where you can see all permissions grouped by type. Tap Camera, for example, and you will see every app that has asked for camera access, with a toggle next to each one. This view lets you change multiple apps at once without hunting through individual app settings.
Key Takeaways
- Open Settings, find the app name, and tap it to see what permissions that app has requested.
- You can also go to Settings > Privacy & Security and choose a permission type to see all apps using it at once.
- Toggling a permission off does not delete the app — it just blocks that specific access until you turn it back on.
- Some apps will ask for permission again the next time they need it, depending on how the developer coded the request.
Permissions you will see most often
Location is the most common permission request. Apps ask for it to show you nearby restaurants, weather for your area, or directions. You can set it to Always, While Using, or Never. Always means the app can track your location even when you are not using it — useful for navigation apps but risky for social media. While Using is the middle ground: the app sees your location only when it is open.
Camera and Microphone are straightforward: the app either can or cannot access them. Messaging apps, video call apps, and social media often ask for both. If you deny camera access to a video app, you can still use it for audio calls.
Photos lets an app see your photo library. Some apps ask for this to let you attach photos to messages or posts. Others ask just to set a profile picture. You can also choose to give access to only selected photos instead of your entire library — when you tap Photos in the permission settings, you will see an option to "Select Photos" instead of "All Photos".
Contacts, Calendar, and Reminders are personal data. Messaging apps often ask for Contacts so they can suggest people to message. Calendar apps obviously need Calendar access. Email apps ask for Contacts to auto-fill addresses.
How to deny a permission without breaking the app
Turning off a permission does not crash the app or delete it. The app will either work around the missing permission or ask you again the next time it needs it. A photo editing app without camera access will still let you edit photos from your library — you just cannot take a new photo inside the app.
Some apps will nag you repeatedly if you deny a permission they consider essential. If an app keeps asking for location access and you do not want to give it, you have two choices: keep tapping Don't Allow each time it asks, or uninstall the app. There is no way to silence the requests permanently without one of those two steps.
A few apps will refuse to run at all without certain permissions — a voice recorder needs microphone access, for example. If you deny that permission, the app will show an error message telling you to turn it back on in Settings.
Changing permissions for apps you no longer use
If you have an old app installed that you never open, it may still have permission to access your camera, location, or contacts. Go through Settings > Privacy & Security and look for apps you recognize but do not use. Turning off their permissions takes 10 seconds and closes a door you do not need open.
You do not have to uninstall the app to revoke its permissions. Just toggle off the ones you do not want it to have. The next time you open that app, it may ask for the permission again, but you can keep saying no.
What happens when an app asks for a permission you already denied
If you tap Don't Allow when an app first asks for a permission, the app will ask again the next time it needs that access — unless you chose "Don't Allow" in the permission settings itself, which is permanent until you change it back. The difference matters: a one-time denial is not the same as a setting.
When the app asks again, you will see the same dialog with three buttons: Allow, Don't Allow, and Ask Next Time. Choose Ask Next Time if you want to decide case by case. Choose Don't Allow if you never want to give that permission. Choose Allow if you have changed your mind.
Checking which apps have location access right now
Go to Settings > Privacy & Security > Location Services. You will see a list of every app that has asked for location permission, with a status next to each one: Always, While Using, or Never. A small arrow icon next to an app means it has used location in the last 24 hours.
This list is useful for finding apps you forgot you installed. If you see an app you do not recognize, you can tap it and change its setting to Never, or uninstall it entirely from the App Store.
Resetting all permissions for an app
There is no button to reset all permissions at once. If you want to start fresh with an app, the only way is to uninstall it and reinstall it from the App Store. When you open it for the first time after reinstalling, it will ask for all permissions again, and you can choose which ones to allow.
This is useful if an app is behaving strangely or if you denied a permission by accident and the app stopped asking. Reinstalling takes a few minutes but clears out any permission confusion.
Frequently Asked Questions
Can I give an app permission to use my camera only once?
Not exactly, but you can set it to Ask Next Time. Then the app will ask for permission each time it wants to use the camera, and you can say yes or no each time. This is different from Always, which lets it use the camera without asking.
Why does an app keep asking for permission even though I already said yes?
The app may have been updated and is asking for a new permission it did not need before. Or the app may be coded to ask every time it needs that access, even if you already said yes. Check Settings to see what permission status is actually set — if it says Allow, the app should not be asking.
If I turn off location for an app, will it still work?
Most apps will still work, but some features may not. A maps app without location access cannot show you where you are, but you can still search for addresses and get directions. A weather app without location will not show your local forecast, but you can manually enter a city.
Can I give an app access to only some of my photos instead of all of them?
Yes. When you tap Photos in the app's permission settings, you will see an option to Select Photos. Tap it, and you can choose which photos and videos the app can see. You can change this selection anytime by going back to that setting.
What does "Ask Next Time" mean for permissions?
It means the app will ask you for permission the next time it needs that access. You will see a dialog with Allow and Don't Allow buttons. This is useful if you want to decide each time instead of giving blanket permission.
