Most Private Phone Settings — iOS & Android 2026

Your phone knows more about you than any other device — your location 24/7, your contacts, your photos, your health data, your browsing history. Here is how to lock it down. Updated March 2026.

iOS Privacy Settings (iPhone/iPad)

1. Disable Ad Tracking

1. Go to Settings → Privacy & Security → Tracking
2. Turn off "Allow Apps to Request to Track"
3. This disables the IDFA (Identifier for Advertisers). Apps can no longer track you across other companies' apps and websites.

2. Limit Location Access

1. Go to Settings → Privacy & Security → Location Services
2. Review each app's location access. Set most apps to "While Using" or "Never"
3. Turn off "Precise Location" for apps that do not need exact coordinates (social media, news, shopping)
4. Under System Services (bottom of Location Services): disable "iPhone Analytics," "Routing & Traffic," "Improve Maps," and "Significant Locations"

3. App Privacy Audit

1. Go to Settings → Privacy & Security → App Privacy Report
2. Enable it. After a week, review which apps access your camera, microphone, contacts, and location — and how frequently
3. Remove access for apps that should not need specific permissions

4. Safari Privacy

• Go to Settings → Safari
• Enable "Prevent Cross-Site Tracking"
• Enable "Hide IP Address" (from trackers, or from trackers and websites)
• Set "Block All Cookies" if you can tolerate some sites breaking (or leave cross-site tracking prevention on)
• Disable "Search Engine Suggestions" and "Safari Suggestions" to reduce data sent to Apple

5. Additional iOS Settings

• Settings → Privacy & Security → Analytics & Improvements: Turn off all options (Share iPhone Analytics, Improve Siri, etc.)
• Settings → Privacy & Security → Apple Advertising: Turn off "Personalized Ads"
• Settings → Mail → Privacy Protection: Enable "Protect Mail Activity" to block email tracking pixels
• Settings → Phone → Silence Unknown Callers: Enable to block spam calls
• Lock Screen: Disable Control Center, Notification Center, Siri, and Reply with Message from the lock screen (Settings → Face ID & Passcode)

Android Privacy Settings

1. Disable Ad Tracking

1. Go to Settings → Privacy → Ads (or Settings → Google → Ads)
2. Tap "Delete advertising ID" — this permanently removes your ad tracking ID. Apps can no longer use it for cross-app tracking.

2. App Permissions Audit

1. Go to Settings → Privacy → Permission Manager
2. Review each permission category: Camera, Microphone, Location, Contacts, Files, Phone, SMS
3. For each app, choose: "Allow only while using the app," "Ask every time," or "Don't allow"
4. Pay special attention to Camera and Microphone — apps should not have background access to these
5. Check "Nearby Devices" permission — used for Bluetooth tracking

3. Location Settings

• Go to Settings → Location
• Tap "App location permissions" and set most apps to "While using" or "Denied"
• Disable "Google Location History" and "Web & App Activity" in your Google Account settings (these are separate from device location permissions)
• Go to myactivity.google.com and delete stored location data, search history, and YouTube history

4. Additional Android Settings

• Settings → Privacy → Privacy Dashboard: View a timeline of which apps accessed sensitive permissions in the last 24 hours
• Settings → Privacy: Enable "Camera access" and "Microphone access" indicators (show a green dot when in use)
• Settings → Security: Enable "Google Play Protect" to scan for malicious apps
• Disable lock screen notifications or set to "Show sensitive content only when unlocked"
• Review connected apps: Go to myaccount.google.com → Security → Third-party apps with account access. Remove anything you do not use.

Universal Tips (Both Platforms)

• Use a VPN — especially on public WiFi. See our VPN guide.
• Use encrypted messaging: Signal is the gold standard. iMessage is good for Apple-to-Apple communication.
• Update your phone: Security patches fix vulnerabilities that attackers exploit. Enable automatic updates.
• Review app permissions after updates: Some apps request new permissions after updates. Do not auto-approve.
• Uninstall unused apps: Every installed app is a potential data collector, even if you never open it.
