Smartphone Privacy Secrets: Protecting Your Phone from Spies and Trackers

Introduction

In today’s connected world, your smartphone knows more about you than you might think. This guide will help you protect your privacy by stopping unnecessary tracking, listening, and data sharing.

Disabling Location Tracking

1. Turn off GPS when not in use — Your GPS pinpoints your exact location. Turn it off in your settings when you’re not using maps or navigation to avoid apps tracking your movements.

   • Example: If you’re relaxing at home and not using maps, switch off GPS to prevent background tracking.

2. Disable location history — Some services save your location history. Turn off this feature to prevent creating a timeline of your whereabouts.

   • Example: Google Maps saves your travel history unless you disable location history.

3. Limit location access for apps — Set apps to use your location only when they’re open.

   • Example: Allow location access only for a weather app while you’re checking the forecast, not all the time.

4. Disable Wi-Fi and Bluetooth scanning — Even if Wi-Fi and Bluetooth are off, your phone might still scan for networks, which can track your location.

   • Example: Disable scanning in your settings to stop your phone from searching for public Wi-Fi networks.

5. Use airplane mode in public places — Airplane mode turns off all wireless signals, making it harder to track your device.

   • Example: When commuting or in crowded areas, enable airplane mode to prevent unnecessary signals.

6. Avoid connecting to public Wi-Fi — Public networks are often unsecured and can track your device.

   • Example: Instead of connecting to airport Wi-Fi, use mobile data or a personal hotspot.

7. Disable location tagging on photos — Photos can store location data. Turn off geotagging in your camera settings.

   • Example: A vacation photo shared on social media could show the exact location where it was taken.

8. Turn off background location tracking — Some apps continue tracking location even when not open.

   • Example: Check the settings for apps like fitness or delivery services to ensure background tracking is off.

Managing App Permissions

9. Revoke unnecessary app permissions — Review what permissions apps have and remove those that aren’t needed.

   • Example: If a game app asks for microphone access, revoke it unless the app genuinely needs it.

10. Restrict microphone and camera access — Only give apps access to your microphone and camera when necessary.

• Example: Disable camera access for social media apps until you need to record or take a photo.

11. Use permission reminders — Some phones can alert you when apps use permissions.

• Example: Enable reminders so you’re notified if an app accesses your microphone unexpectedly.

12. Disable background app refresh — Stop apps from updating in the background to prevent unwanted data usage.

• Example: Social media apps often refresh in the background and send data without your knowledge.

13. Turn off app location sharing — Avoid granting apps permission to share your location with third parties.

• Example: A ride-sharing app might request to share your trip history — disable this in its privacy settings.

14. Review permissions after app updates — Some apps reset permissions after updates.

• Example: After updating your messaging app, check to see if it re-enabled access to your contacts or storage.

15. Avoid apps that request excessive permissions — Some apps may ask for more access than needed.

• Example: A flashlight app asking for contact access is a red flag.

Securing Communications

16. Use encrypted messaging apps — Apps like Signal or WhatsApp provide secure, end-to-end encryption.

• Example: Messages sent on these apps can’t be read by anyone except the sender and receiver.

17. Enable disappearing messages — Automatically delete messages after a set time to keep conversations private.

• Example: Set messages in Signal to disappear after 24 hours.

18. Use two-factor authentication (2FA) — Add an extra layer of security to messaging and email apps.

• Example: A login will require both your password and a code sent to your phone.

19. Avoid SMS for sensitive communications — Text messages can be intercepted.

• Example: Avoid sending passwords or private information via SMS.

20. Enable encryption on your phone — Encrypt your phone’s storage to secure your files.

• Example: Encryption ensures that even if someone steals your phone, they can’t read your files.

21. Disable automatic message previews — Prevent notifications from showing message content on your lock screen.

• Example: Set your phone to display only “New message” instead of the actual message content.

22. Use secure email services — Choose encrypted email providers like ProtonMail.

• Example: ProtonMail encrypts emails so only you and the recipient can read them.

23. Clear communication history regularly — Delete old call logs and messages to minimize stored data.

• Example: Clear messaging apps of past conversations to reduce exposure if your phone is compromised.

Preventing Ad Trackers and Data Collection

24. Disable personalized ads — Prevent advertisers from using your data to show targeted ads.

• Example: Turn off ad personalization in Google or Apple settings.

25. Clear browser cookies and cache — Delete cookies to stop websites from tracking your browsing habits.

• Example: Clear cookies in your browser settings after visiting e-commerce sites.

26. Use private browsing modes — Prevent websites from saving your browsing history.

• Example: Use “Incognito Mode” in Chrome when researching private topics.

27. Install browser extensions that block trackers — Use tools like uBlock Origin or Privacy Badger.

• Example: These extensions prevent trackers from loading when you visit websites.

28. Disable ad tracking in apps — Some apps collect data for targeted advertising.

• Example: Disable tracking options in the settings of social media apps.

29. Review app privacy policies — Check what data the app collects and choose alternatives if necessary.

• Example: Avoid apps that collect and share your contacts without reason.

30. Opt out of location-based ads — Turn off ads that track your physical location.

• Example: Disable location-based ads in your phone’s privacy settings.

Best Privacy and Security Apps

31. Install a reputable VPN — VPNs encrypt your internet traffic to protect it from eavesdropping.

• Example: Use NordVPN or ExpressVPN for secure browsing.

32. Use ad-blockers — Block intrusive ads and trackers.

• Example: Install AdGuard on your browser to block ads.

33. Install anti-tracking software — Prevent tracking scripts from collecting your data.

• Example: Use Ghostery to block tracking.

34. Choose encrypted email providers — Use secure email services to send private communications.

35. Use a password manager — Generate and store strong passwords securely.

• Example: Use LastPass to store unique passwords for each account.

36. Enable biometric authentication — Add security with fingerprint or facial recognition.

• Example: Set up fingerprint unlock for your apps.
