A walkthrough of the privacy controls hiding in your smartphone — what each setting does and which ones are worth turning on or off.

Key Takeaways

  • Most phones ship with privacy settings that favor data sharing — you have to opt out manually.
  • Location, microphone, and camera permissions are among the highest-risk access points to review.
  • Limiting ad tracking and diagnostic sharing costs you nothing in day-to-day usability.
  • Both iPhone (iOS) and Android offer granular privacy controls, though menus differ by device.
  • A quick settings audit once or twice a year goes a long way toward protecting your personal data.

Why Your Phone's Default Settings Aren't Set Up for You

When you pull a new smartphone out of the box, it's pre-configured to share quite a bit — your location, your usage habits, diagnostics, even personalized advertising identifiers. That's not necessarily sinister, but it does mean the default setup tends to favor the manufacturer and app developers more than it favors you.

The good news: your phone is full of privacy controls that are yours to adjust. You don't need a tech background to use them. This checklist walks through the key settings, organized by category, so you can work through them at your own pace. Steps apply broadly to both iPhone (iOS) and Android, though exact menu names may vary by device and software version.

For a deeper look at how the two platforms compare on privacy, see how iPhone and Android differ for everyday users. And if you want to understand what app permissions actually grant before you start revoking them, this plain-language guide to app permissions is a helpful starting point.

Location Access

Open Location Services (Settings > Privacy & Security > Location Services on iOS; Settings > Location on Android) and review which apps have access. Must
Change any app set to 'Always' to 'While Using' or 'Never' unless you have a specific reason for background location tracking. Must
Disable 'Precise Location' for apps that don't genuinely need it — a weather app needs your city, not your exact street address. Should
Turn off 'Share My Location' with contacts you no longer wish to share with (iOS: Settings > [Your Name] > Find My > Share My Location). Should

Camera and Microphone

Review which apps have camera access and revoke it for any app that has no obvious need to take photos or scan documents. Must
Review microphone access and remove it from apps that don't record audio, make calls, or require voice input as part of their core function. Must
On Android, check whether any apps have accessed your camera or microphone recently using the Privacy Dashboard (Settings > Privacy > Privacy Dashboard). Should

Contacts, Calendars, and Files

Check which apps can read your contacts list and remove access from any that don't need it to function — a game or utility app rarely has a good reason to see your address book. Must
Audit calendar access and restrict it to apps that genuinely schedule or manage events on your behalf. Should
Review photo library access; switch apps from 'Full Access' to 'Selected Photos' wherever possible so they can only see what you explicitly allow. Should

Advertising and Tracking

On iOS, go to Settings > Privacy & Security > Tracking and toggle off 'Allow Apps to Request to Track' to stop cross-app tracking requests. Must
On Android, go to Settings > Privacy > Ads and opt out of personalized ads, or reset your advertising ID. Must
Review any 'Personalization' or 'Ad Customization' settings in Google or Apple account settings and turn off what you don't want. Should

Diagnostics and Usage Data

On iOS, go to Settings > Privacy & Security > Analytics & Improvements and turn off 'Share iPhone Analytics' and 'Improve Siri & Dictation' if you prefer not to send usage data. Should
On Android, check Settings > Privacy > Usage & Diagnostics and disable automatic sharing of diagnostic reports. Should
Disable 'Personalized Suggestions' features that rely on reading your behavior across apps if you'd rather keep those habits private. Nice to have

Lock Screen and Biometrics

Ensure your phone has a strong passcode — at least six digits, or an alphanumeric code — rather than a simple four-digit PIN. Must
Review what information appears on your lock screen (notifications, widgets) and hide sensitive content from showing before unlock. Must
Decide intentionally whether Face ID, fingerprint unlock, or both are enabled, and remove any saved biometric data from people who should no longer have access. Should

Bluetooth and Network

Turn off Bluetooth when you're not actively using a paired device — it can be used to track your location in some environments. Nice to have
Review which apps have access to your local network (visible on iOS under Settings > Privacy & Security > Local Network) and revoke access for apps with no networking purpose. Should
Disable Wi-Fi auto-join for open networks to prevent your phone from silently connecting to unknown hotspots. Should

Tools You'll Need Before You Start

No downloads required — everything below lives inside settings your phone already has. Grab a few minutes of uninterrupted time and keep your phone nearby.

Required

Your phone's Settings app

The central hub for all privacy and permission controls on both iOS and Android.

Required

Your phone's OS version info

Knowing your current iOS or Android version helps you find the right menu names, since settings screens vary across versions.

Optional

A notepad or notes app

Useful for jotting down any settings you change so you can reference them later or undo if something breaks.

Revoking Permissions May Break Some Features

Some apps will partially stop working if you remove a permission they rely on — a navigation app with no location access can't give directions, for example. Make changes one app at a time and test before moving on. If something stops working unexpectedly, you can always restore access through the same settings menu.

After the Audit: Keep It Going

Privacy settings aren't a one-time fix. Apps update, permissions reset after OS upgrades, and new apps you install will ask for access all over again. Build a habit of checking permissions whenever you install something new, and do a fuller audit every few months.

If you share your phone with a child, the stakes are higher — our parent's guide to protecting children online covers additional steps worth taking. And if you travel frequently, take a look at protecting your data when you travel, since public Wi-Fi and shared devices introduce different risks.

Finally, keep in mind that deleting an app doesn't always wipe its data. What stays behind after you uninstall explains what typically lingers and what you can do about it. For broader guidance on staying safe online, visit the Online Safety hub.

These Settings Don't Replace Strong Passwords

Privacy settings control what data your phone shares, but they don't protect you if someone gains access to your accounts with a weak or reused password. Use a unique, strong password for your phone's primary account (Apple ID or Google account) and enable two-factor authentication. These two steps do more to protect your data than almost anything else on this list.
