Your smartphone knows more about you than any other device you own. It tracks where you go, who you talk to, what you search for, and what you buy. Whether you just got a new phone or want to reconfigure the one in your pocket, this guide walks you through every step of setting up a smartphone that respects your privacy — from the first power-on screen to the apps you install and the settings you lock down.
Step 1: Choose Your Platform — iOS vs Android
The operating system you choose sets the baseline for your privacy. iOS offers strong default protections, including App Tracking Transparency (ATT), privacy nutrition labels in the App Store, and on-device data processing. The tradeoff is less customization. Android is built by Google, so defaults lean toward data collection — but recent versions (Android 14 and 15) offer granular controls including the Privacy Dashboard and photo picker permissions. For maximum privacy on Android, consider GrapheneOS on a Pixel device.
iOS is more private out of the box. Android can match it with effort. Either platform can be hardened significantly using the steps below.
Step 2: Initial Setup — Disable Telemetry and Limit Ad Tracking
The setup wizard on both platforms will ask you to enable features that benefit the manufacturer more than you. Disabling telemetry and ad tracking during initial setup is the single most important step you can take.
On iOS
- Decline "Share Analytics" to stop telemetry data from being sent to Apple and developers.
- Disable Location Services during setup — enable them selectively later.
- Go to Settings > Privacy & Security > Tracking and turn off "Allow Apps to Request to Track" to block cross-app ad tracking.
- Navigate to Settings > Privacy & Security > Apple Advertising and disable Personalized Ads.
On Android
- Decline "Send usage and diagnostic data" to stop telemetry from being sent to Google.
- Skip Google Assistant setup — voice assistants send recordings to cloud servers.
- Go to Settings > Security & Privacy > Ads and tap "Delete advertising ID" to remove the persistent ad tracking identifier.
- Disable Ad topics, App-suggested ads, and Ad measurement to block remaining ad tracking signals.
First-Run Tip
Both iOS and Android make it easy to say "yes" to everything during setup and difficult to find these settings later. Take the extra two minutes during initial configuration to decline telemetry and analytics. It is far easier to opt out now than to undo permissions after the fact.
Step 3: Audit and Restrict App Permissions
App permissions are the single biggest privacy lever on your phone. Most apps request far more access than they need.
Key Permissions to Restrict
- Location: Set to "While Using" or "Never" for most apps. Only navigation and ride-sharing apps genuinely need background location.
- Camera and Microphone: Set to "Ask Every Time" so you consciously approve each use.
- Contacts: Deny unless the app's core function requires it (messaging apps, not games).
- Photos: On iOS 17+, use "Limited Access" to share only selected photos instead of your entire library. On Android 14+, use the photo picker.
- Bluetooth: Many apps request Bluetooth to track your location via beacons. Deny unless you are connecting to a specific device.
On iOS, review permissions under Settings > Privacy & Security. On Android, use Settings > Security & Privacy > Permission Manager. Make this a quarterly habit — permissions granted six months ago may no longer be necessary.
Watch Out for Overprivileged Apps
If a flashlight app asks for your contacts, or a weather app wants background location access, treat it as a red flag. Legitimate apps only request permissions tied to their core functionality. Apps that demand excessive access are often monetizing your data behind the scenes. Delete them and find alternatives.
Step 4: Install Privacy-Focused App Alternatives
The default apps on your phone — browser, email, maps, keyboard — are often the biggest data collectors. Replacing them makes a dramatic difference.
- Browser: Replace Chrome or Safari with Brave or Firefox. Both block trackers and ads by default, and Brave includes fingerprinting protection.
- Email: Switch to Proton Mail or Tuta for end-to-end encrypted email. At minimum, use email aliases through SimpleLogin or Apple's Hide My Email.
- Messaging: Use Signal for end-to-end encrypted conversations. It collects virtually no metadata and is open-source. Avoid SMS for sensitive conversations.
- Maps: Replace Google Maps with Organic Maps or OsmAnd — both work offline and do not track location history. Apple Maps is reasonable on iOS.
- Keyboard: Your keyboard sees everything you type. Use OpenBoard on Android or the stock Apple keyboard on iOS with "Allow Full Access" disabled for third-party keyboards.
Step 5: Set Up a VPN
A VPN encrypts your internet traffic and hides your IP address from websites, your ISP, and anyone on the same network. Choose a provider with a verified no-logs policy:
- Proton VPN — free tier available, based in Switzerland, open-source and independently audited.
- Mullvad VPN — accepts anonymous payment, no email required.
- NordVPN or Surfshark — mainstream options with strong no-logs policies.
Enable the kill switch and set it to connect automatically on untrusted networks. Avoid free VPNs — many log and sell your browsing data.
Step 6: Lock Down Location Services
Location data is among the most sensitive information your phone collects. Beyond per-app permissions, there are system-level settings that contribute to location tracking.
On iOS
- Go to Settings > Privacy & Security > Location Services > System Services and disable: Location-Based Apple Ads, Location-Based Suggestions, Significant Locations (tap to clear history), and iPhone Analytics.
- Disable "Share My Location" unless you actively use Find My with trusted family members.
On Android
- Go to Settings > Location > Location Services and disable Wi-Fi scanning and Bluetooth scanning — these track your position even when Wi-Fi and Bluetooth are turned off.
- Disable Google Location Accuracy to limit location to GPS only.
- In your Google Account settings, pause Location History (Timeline) and delete any stored location data.
Step 7: Use App Store Privacy Labels
Both platforms now display privacy labels for each app before you install it. On iOS, check the "App Privacy" section to see what data an app collects, whether it is linked to your identity, and whether it is used for tracking. On Google Play, look for the "Data safety" section showing what data is collected and shared.
Make it a habit to check these privacy labels before installing any new app. If the data collection seems disproportionate to the app's purpose, find an alternative. A few seconds of reading can save you from apps that quietly harvest contacts, location, and browsing data.
Step 8: Back Up Securely
Backups are essential, but they can be a privacy vulnerability if stored unencrypted in the cloud.
On iOS, enable Advanced Data Protection under Settings > [Your Name] > iCloud > Advanced Data Protection. This applies end-to-end encryption to iCloud backups, photos, and notes — meaning even Apple cannot access them.
On Android, Google holds encryption keys for most backup data types. For stronger protection, use a local backup solution or review what is included under Settings > Google > Backup and disable categories you do not want on Google's servers. For both platforms, avoid backing up to services that do not offer end-to-end encryption.
Step 9: Remove Your Data From Broker Sites
Every step in this guide protects data going forward — but it does nothing about personal information already out there. Data brokers like Spokeo, BeenVerified, and Whitepages have likely already collected your name, address, phone number, and family details. PrivacyOn automates removal across 100+ data broker sites and continuously monitors for re-listings. With plans starting at $8.33 per month and family coverage for up to 5 people, it complements the device-level protections in this guide by addressing data already circulating beyond your phone.
Putting It All Together
A truly privacy-focused smartphone is not about one setting or one app — it is a combination of deliberate choices across your entire device. Here is a quick checklist:
- Choose iOS for easier defaults or Android for deeper customization.
- Disable telemetry and decline analytics during initial setup.
- Delete your advertising ID and disable all ad tracking.
- Audit every app permission — deny anything non-essential.
- Replace default apps with privacy-respecting alternatives.
- Install and enable a trusted VPN.
- Lock down location services at both the app and system level.
- Check app store privacy labels before installing new apps.
- Enable encrypted backups.
- Use PrivacyOn to remove existing data from broker sites.
Privacy is not a one-time setup. Revisit your permissions and settings every few months, stay aware of new tracking techniques, and treat your phone as a device that works for you — not for advertisers, data brokers, or anyone else.
