Understanding Privacy Settings on Your Phone
What Is This in Plain English?
Think back to the 1970s, when you had a personal address book — a small notebook where you kept everyone's phone numbers, home addresses, and birthdays. You would never leave that book sitting open on a park bench for strangers to read. You kept it private, tucked safely in your purse or drawer.
Your smartphone is that address book, multiplied a thousand times over. It holds your contacts, your photos, your location, your health information, and more. Privacy settings are simply the locks you put on that notebook — they control which apps and companies are allowed to peek inside, and which ones are politely shown the door.
Why This Matters More Than You Might Think
Every app you download — a game, a weather app, a shopping tool — may ask for permission to access parts of your phone. Some of these requests are perfectly reasonable. Many are not.
A flashlight app, for example, has no good reason to know your exact location or read your contacts. Giving unnecessary access is like hiring a plumber to fix your sink and then handing him the keys to every room in your house.
This article will walk you through exactly how to see who has access to what — and how to take that access back.
🛡️ Safety Alert: Reviewing your privacy settings once every few months is one of the single most effective things you can do to protect yourself from scams, identity theft, and unwanted tracking. It takes less than 15 minutes.
Part 1: Privacy Settings on an iPhone (Apple)
Step 1: Open Your Settings
- Find the Settings app on your iPhone's home screen. It looks like a small gray square with a silver gear or cog wheel on it — similar to a mechanical wheel you might find inside an old wristwatch.
- Tap on it once to open it.
Step 2: Find the Privacy & Security Section
- Slowly scroll down the Settings menu. You are looking for the words Privacy & Security.
- To the left of those words, you will see a small blue square icon with a hand holding up one finger — like the universal "just a moment" gesture.
- Tap on Privacy & Security.
Step 3: Review Who Can See Your Location
Your location is one of the most sensitive pieces of information on your phone. This tells apps — and the companies behind them — exactly where you are, sometimes at all times.
- Tap on Location Services at the very top of the Privacy & Security screen.
- You will see a list of every app on your phone that has ever asked to know your location.
- Tap on any app name to see its current setting. You will have these choices:
| Option | What It Means |
|---|---|
| Never | This app cannot see your location at all |
| Ask Next Time | The app will ask your permission each time before looking |
| While Using the App | The app can only see your location when you are actively using it |
| Always | The app can see your location 24 hours a day, even when you are not using it |
- For most apps — shopping, games, news — choose Never or Ask Next Time. Only mapping or navigation apps like Apple Maps truly need While Using the App.
🛡️ Safety Alert: If you see an app set to Always that has no obvious reason to track you constantly — a recipe app, a Bible app, a solitaire game — change it to Never immediately. This is a common way companies collect and sell data about your daily habits without your full knowledge.
Step 4: Review Your Camera and Microphone Access
Some apps ask to use your phone's camera or microphone. A video calling app like FaceTime absolutely needs this. A crossword puzzle app does not.
- Go back to the Privacy & Security screen.
- Tap on Camera. You will see a list of all apps with camera access. Any app that should not need a camera — tap the green toggle switch next to its name to turn it off (the switch will slide left and turn gray, like a light switch being flipped off).
- Go back and tap on Microphone. Do the same review. Turn off microphone access for any app that has no good reason to listen.
💡 Pro Tip: A toggle switch that is green and pushed to the right means the permission is ON. A toggle that is gray and pushed to the left means it is OFF. This is your on/off switch for each permission.
Step 5: Check Which Apps Can See Your Contacts
Your contacts list contains the names, phone numbers, and addresses of people you love. Guard it carefully.
- On the Privacy & Security screen, tap Contacts.
- Review the list. Social media apps and calling apps may have a legitimate need. Games, calculators, and flashlight-type apps absolutely do not.
- Tap the green toggle to turn off access for any app that should not have it.
Part 2: Privacy Settings on an Android Phone (Samsung, Google, etc.)
Android phones are made by several different companies, so your screen may look slightly different from these instructions. However, the steps below will work on most Android phones.
Step 1: Open Your Settings
- Find the Settings app. On Android, it almost always looks like a gray or white gear wheel — again, like the cog inside a clock.
- Tap on it to open it.
Step 2: Find the Privacy Menu
- Scroll down until you see the word Privacy. It may also appear under a section called Security & Privacy depending on your phone's brand.
- Tap on Privacy.
Step 3: Use the "Permission Manager"
Android has a very helpful tool called the Permission Manager that organizes everything neatly by category.
- Inside the Privacy menu, tap on Permission Manager.
- You will see a list of categories: Camera, Microphone, Location, Contacts, Calendar, and more.
- Tap each category to see which apps have been granted that permission.
- Tap any app name inside a category to change its access. You will see options similar to the iPhone: Allow, Allow Only While Using, Ask Every Time, or Don't Allow.
- For anything that seems unnecessary, select Don't Allow.
💡 Pro Tip: Start with Location, Camera, and Microphone — these three are the most commonly misused by apps and the most important to review first.
Step 4: Turn Off Ad Tracking
Both iPhones and Android phones allow advertisers to follow your behavior across apps to show you targeted advertisements. You can limit this.
On iPhone:
- Go to Settings > Privacy & Security.
- Scroll to the very bottom and tap Tracking.
- Make sure the toggle next to Allow Apps to Request to Track is turned off (gray, slid to the left).
On Android:
- Go to Settings > Privacy.
- Look for Ads or Advertising ID.
- Tap Delete Advertising ID or turn off Opt out of Ads Personalization. The exact wording varies by phone.
🛡️ Safety Alert: Turning off ad tracking does not mean you will stop seeing advertisements. It simply means those ads will no longer be based on your personal behavior and location history. Your information will no longer be sold for this purpose.
Part 3: The "Big Four" Permissions to Always Review
No matter what type of phone you have, these four permissions deserve your closest attention. Review them first, every time.
1. Location — Where you are, at all times. Limit this aggressively. Most apps do not need it.
2. Camera — The ability to take photos and videos using your phone. Only communication and photo apps should have this.
3. Microphone — The ability to listen through your phone. Voice assistants and calling apps need this. Almost nothing else does.
4. Contacts — Your personal address book. Social and calling apps may need it. Guard this one like the address book on your nightstand.
How to Stay Safe While Managing Privacy Settings
Go slowly and make one change at a time. After each change, check that your important apps still work normally before moving on. If something stops working, you can always go back and turn the permission on again.
Never let a stranger do this for you remotely. If anyone calls you — even claiming to be from Apple, Google, or your phone company — and asks to access your settings or "fix your privacy" for you, hang up. This is always a scam.
Write down any changes you make. Keep a small notepad next to your chair. Jot down which app you changed and what you changed it to. This way, if something stops working, you have a simple record to reference.
Do not rush. There is no time limit on these screens. Take all the time you need to read each option carefully before tapping anything.
🛡️ Safety Alert: Legitimate companies do not need to call you to "update your privacy settings." If you receive such a call or a pop-up message on your screen that creates urgency — "Your privacy is at risk! Call now!" — do not call the number. Close the message and call a trusted family member instead.
A Simple Routine: Your Monthly Privacy Check
Think of this like checking that your doors are locked before bed. Once a month, spend 10 quiet minutes doing the following.
- Open Settings on your phone.
- Go to Privacy (iPhone: Privacy & Security / Android: Privacy > Permission Manager).
- Check Location, Camera, Microphone, and Contacts — in that order.
- Turn off any permission that does not make obvious sense for that app.
- Close Settings and carry on with your day.
💡 Pro Tip: Pick the same day each month so it becomes a habit — perhaps the first Sunday, or the day you pay your bills. Pair it with a cup of tea and it becomes five minutes of quiet, productive peace of mind.
You Are Now in Control
Privacy settings are not about fear — they are about choice. Your phone is yours, and the information inside it belongs to you. These settings simply make sure it stays that way.
If at any point you feel uncertain or overwhelmed, your local Apple Store, phone carrier store, or even your local library's technology help desk will be glad to sit with you and walk through these steps together. You are never expected to figure this out alone.
