Your Phone Knows More About You Than You Think — 7 Privacy Settings to Review

Your smartphone probably knows where you live. It may know where you work, which routes you take, who you speak to, which photographs you save, which apps you use and what you search for.

That doesn't automatically mean something sinister is happening.
Much of this information enables genuinely useful features: maps need location, messaging apps may need contacts, camera apps need camera access, and voice assistants require microphone access.

The problem begins when we stop noticing which apps have access to what-and whether they still need it.

Modern Android phones and iPhones offer considerably more privacy controls than many users realise. A few minutes inside your settings can reveal apps with permissions you have granted months or even years ago.

Here are seven privacy settings worth reviewing today.

1. Check Which Apps Can See Your Location

Location is one of the most sensitive permissions on a smartphone.

Some apps genuinely need it.
Navigation apps need your position to give directions.
Ride-hailing services need to know where to pick you up.
Weather apps may use your location to provide local forecasts.

But does every shopping app, game or utility need continuous access to where you are?
Probably not.

Always keep an eye on what kind of apps have the permission to your location and do they really require it. Here are a few permissions that you need to check for ensuring that only apps that you allow can read your location.

On Android

Go to: Settings → Location → App location permissions
Depending on your Android version, apps may be grouped into categories such as:

- Allowed all the time
- Allowed only while in use
- Ask every time
- Not allowed

Google also allows users to restrict apps to approximate rather than precise location in supported cases.

On iPhone

Go to: Settings → Privacy & Security → Location Services
Review each app individually. 

Ask yourself: Does this app need my location when I'm not actively using it?
If not, consider switching from Always to While Using the App, or disabling access altogether.
 

Privacy Rule : Give apps the minimum permission necessary for the feature you actually use.

2. Review Camera and Microphone Permissions

Your microphone and camera deserve special attention because they can capture information directly from your surroundings.
Video-calling apps obviously need them.
A photo-editing app may need camera access.

But if an unrelated app has permanent microphone permission and you can't remember why you enabled it, that's worth checking.
Android's permission controls let users review which apps can access the camera and microphone, and newer Android versions show a green privacy indicator when either sensor is being used.

On Android

Try: Settings → Security & Privacy → Privacy → Permission Manager
Then review:
Camera
Microphone
You can usually choose between options such as:

- Allow while using the app
- Ask every time
- Don't allow

Some Android devices also let you disable camera or microphone access system-wide through Quick Settings.

On iPhone

Go to: Settings → Privacy & Security → Camera
And: Settings → Privacy & Security → Microphone
Disable apps that no longer need access.

A useful question: If you deleted the feature that required the permission-or haven't used it in months-why is the permission enabled?

3. Look at Your Privacy Dashboard or Privacy Report

Permissions become more useful when you can see whether apps are actually using them.
Android's Privacy Dashboard lets users inspect recent permission activity. 

On Android 13, for example, it can show app access over the previous seven days for areas such as camera, microphone and location.

Android

Go to: Settings → Security & Privacy → Privacy → Privacy Dashboard
The exact wording varies by manufacturer. You may discover that an app accessed your location far more often than expected.

iPhone

Apple provides App Privacy Report: Settings → Privacy & Security → App Privacy Report
When enabled, it can show how frequently apps accessed sensitive information or sensors such as your location, photos, camera, microphone and contacts during the previous seven days. Apple says this report is encrypted and stored on the device.

This is one of the easiest ways to move from:
"I think this app respects my privacy"
To:
"Here's what it has actually been accessing."

4. Stop Giving Every App Your Entire Photo Library

Think about what your photo library can contain.
Family photographs.
Screenshots of conversations.
Travel tickets.
Documents.
Receipts.
Vehicle numbers.
Work information.

Occasionally even identity documents or financial screenshots. That makes photo permission more sensitive than many people realise.
If an app only needs one image for a profile photo, does it need ongoing access to your entire library?

On Apple devices, users can change the level of photo access provided to individual apps.
Android versions and manufacturers may similarly offer options allowing selected-photo access instead of unrestricted access.

What to check

Open your privacy or app-permission settings and look at: Photos and videos
Then ask: Does this app need every photo-or only the ones I choose?
Where available, select limited or selected-photo access.

This small change reduces the amount of personal information available to an app without necessarily reducing its usefulness.

5. Review Contacts, Calendar and Other Sensitive Permissions

When an app asks for your contacts, you aren't only sharing information about yourself.
You may also be sharing information about other people.

Your address book may include:
- names,
- phone numbers,
- email addresses,
- workplaces,
- family relationships,
- and other saved details.
The same principle applies to calendars. Your calendar may reveal meetings, travel plans, medical appointments, addresses and personal routines.
Android's permission manager allows users to review permissions including Contacts, Calendar, Call Logs, SMS, Files and other categories.

Ask one simple question
What feature would stop working if I removed this permission?
If you cannot think of one, test the app without it. You can usually restore permission later if something genuinely stops working.

6. Check Advertising and Cross-App Tracking

Not all tracking involves GPS.
Apps and advertising systems may also use activity signals to personalise ads or measure advertising performance.

Android

Android includes advertising privacy controls where users can manage features such as:

- ad topics,
- app-suggested ads,
- and ad measurement.

Google says these options can be found under: Settings → Google → All Services → Ads → Ads Privacy

The precise path can vary depending on device and Android version. You can also manage advertising identifiers and personalisation controls through Google Play services.

iPhone

Apple's App Tracking Transparency system allows users to decide whether apps can track their activity across other companies' apps and websites.
Go to: Settings → Privacy & Security → Tracking

You can disable tracking permission app by app or switch off Allow Apps to Request to Track. Apple says apps denied tracking cannot access the system advertising identifier and are not permitted to track users through other identifying information for that purpose.

Important distinction: 
Turning off personalised advertising does not necessarily mean you'll stop seeing ads. It generally means fewer ads should be selected based on certain activity or interest information. Google similarly notes that users opting out of personalised ads can still receive advertising, but it may be less relevant to them.

7. Review Permissions You Granted and Forgot About

This may be the most important privacy habit of all.
Most people don't consciously decide: "I want 46 apps to retain access to different parts of my personal information indefinitely."

It happens gradually. Install app. Tap Allow. Try app. Forget app exists. Repeat. Months later, the permission remains.
Android offers controls that can pause activity or remove permissions for apps that haven't been used for a period of time.
Even without automatic tools, a simple manual audit helps.
Once every few months, check:
- Location
- Camera
- Microphone
- Photos
- Contacts
- Calendar
- Files
- Notifications
- Activity or fitness data
- Advertising/tracking permissions
Delete apps you no longer use. Remove permissions that no longer make sense. Privacy becomes much easier when there are fewer apps to manage.

Don't automatically tap "Allow"

Apps are designed to make permission requests feel routine. A pop-up appears. You want to continue. You tap Allow. The better habit is to pause for five seconds.

Ask: Why does this app need this permission?

Then choose the narrowest option that lets the feature work. 

Instead of: Always Allow, consider: While Using the App. 

Instead of: Full Photo Access, consider: Selected Photos.

Instead of: Allow, consider: Ask Every Time.

The objective isn't to deny every permission. It's to make permission intentional.

Privacy Settings Aren't the Whole Story

Changing phone permissions is important, but it doesn't necessarily remove information you've already shared with an online service.
Apple, for example, notes that changing device privacy permissions controls how an app can access data on the device; privacy settings held inside a third-party account may need to be changed separately through that service.
So also review the privacy settings of important accounts such as:
Google.
Meta services.
Microsoft.
Shopping accounts.
Cloud storage.
Fitness services.
Banking and payment apps.
Your phone's permission settings are one layer of privacy-not the entire system.

Convenience and Privacy Don't Have to Be Enemies

There's a tendency to treat digital privacy as an all-or-nothing choice. Either share everything and enjoy convenient apps. Or disable everything and make your smartphone difficult to use. Modern privacy controls offer a much more practical middle ground. Let Maps know your location while you're navigating. Let your camera app use the camera. Let your video-call app use the microphone during calls. 

But perhaps your shopping app doesn't need your location 24 hours a day. Your game probably doesn't need your contacts. And an app you haven't opened for eight months shouldn't continue receiving unnecessary access simply because you once tapped Allow.

A 5-Minute Smartphone Privacy Check

If you don't want to explore every setting today, start with these five:

1. Check apps with "Always" location access.
2. Review microphone and camera permissions.
3. Remove unnecessary photo and contact access.
4. Check advertising and tracking preferences.
5. Delete unused apps or remove their permissions.
That's not perfect privacy. But it's significantly better than never checking at all.

Your Phone Knows a Lot. You Should Know What It Knows.
Smartphones have become extraordinarily personal devices. They're cameras. Maps. Wallets. Calendars. Photo albums. Communication tools. Workstations. Entertainment systems. And increasingly, AI assistants. 

That convenience inevitably creates data. The important question isn't whether your phone knows anything about you. It does. The question is:  Who else can access that information-and have you consciously decided that they should?
Privacy doesn't begin with deleting every app. Sometimes it begins with opening Settings. And looking.
