Is Your Phone Listening to You? A Practical Privacy Guide for Australians

Posted by Security Team on

"I was just talking about needing new running shoes, and now I'm seeing ads for Nikes everywhere on my phone. Is my phone listening to me?"

This is one of the most common questions we get, and the short answer is: probably not in the way you think. But that doesn't mean your concerns about privacy aren't valid – they absolutely are.

The key to effective privacy protection isn't paranoia or complex technical solutions. It's understanding your threat model – what you're actually protecting against – and taking practical steps that match your real-world needs.

Threat models are personal and situation-specific. What works for a government lawyer handling classified information won't be the same as what a retiree needs for basic privacy. The biggest mistake people make is either doing nothing (because it seems too complicated) or trying to implement maximum security for low-risk situations.

This guide will help you understand what's actually happening with your phone, assess your personal privacy needs, and implement practical solutions that match your actual threat level – not someone else's.

Understanding Your Privacy Threat Model First

Before diving into solutions, let's start with the most important concept: your threat model. This simply means understanding what you're protecting, who you're protecting it from, and how much effort you're willing to put in.

Quick Threat Model Assessment

Ask Yourself These Questions:

  1. What information do I actually need to protect?
  2. Who might want access to this information?
  3. What would happen if this information was compromised?
  4. How much inconvenience am I willing to accept for privacy?
  5. Do I handle other people's sensitive information (work, family)?

Low Privacy Needs (Most People):

  • Tired of creepy targeted ads
  • Basic personal privacy preference
  • No sensitive work information
  • Your Focus: Major platform settings + common sense app choices

Medium Privacy Needs (Privacy-Conscious Users):

  • Handle moderately sensitive work information
  • Strong personal privacy values
  • Concerned about identity theft or data breaches
  • Your Focus: Comprehensive settings + selective app usage + some physical security

High Privacy Needs (Professional/Security-Focused):

  • Handle confidential legal, medical, or business information
  • Government, defence, or law enforcement work
  • High-value targets for surveillance or corporate espionage
  • Your Focus: Maximum software protection + physical security tools + operational security practices

Remember: You can move between these categories depending on the situation. A teacher might have low privacy needs personally but high privacy needs when handling student information.

The Reality: How Your Phone Actually "Listens"

What's Actually Happening (The Practical Reality)

Your phone generally isn't secretly recording conversations for ads. Here's what's actually going on:

Data Collection That Matters:

  • Location tracking: Where you go tells advertisers a lot about your interests
  • App behaviour: What you download, use, and delete
  • Web searches: Your search history is incredibly revealing
  • Social media activity: Likes, shares, and time spent on content
  • Purchase data: What you buy online and offline (through loyalty cards)

The "Spooky" Coincidences Explained:
That running shoe ad after your conversation? It's probably because:

  • You've been researching fitness content
  • Your location data shows gym visits
  • People with your demographic profile buy running shoes at this time of year
  • Your friends with similar interests have been looking at athletic gear

The Bottom Line: Advanced data profiling is so sophisticated that it can predict your interests without listening to conversations. This is both less creepy and more concerning than simple audio surveillance.

The Apps That Actually Matter Most

Let's be practical – some apps collect way more data than others. Here's where to focus your attention:

High-Impact Data Collectors (Fix These First):

  • Facebook/Instagram: Extensive tracking across the web
  • Google services: Search, Maps, YouTube, Gmail
  • TikTok: Aggressive data collection, especially among younger users
  • Your phone's default browser: Often shares data with the manufacturer

Medium-Impact Apps:

  • Shopping apps (Amazon, eBay)
  • News apps
  • Weather apps (surprisingly data-hungry)
  • Food delivery apps

Generally Lower Risk:

  • Banking apps (heavily regulated)
  • Government apps
  • Simple utility apps (flashlight, calculator)

The 80/20 Rule: Securing the top 5-6 apps you use most will address about 80% of your privacy concerns. Don't get overwhelmed trying to perfect every single app.

Your Rights as an Australian

Australia has decent privacy laws, but you need to actively use them:

What You Can Actually Do:

  • Request your data from any company (they must respond within 30 days)
  • Ask companies to delete your information
  • Complain to OAIC if companies ignore your requests
  • Opt out of direct marketing

Reality Check: Laws exist, but enforcement is limited. Your best protection is controlling what data companies get in the first place.

Simple Android and iOS Privacy Settings

Let's cut to the chase. Here are the essential privacy settings that actually make a difference, organized by what device you have.

Android Privacy Essentials (5 Minutes)

Step 1: Google Account Settings

  1. Open Settings → Google → Manage your Google Account
  2. Go to "Data & privacy" → "Ad settings"
  3. Turn off "Ad Personalisation"
  4. Under "Activity controls," pause:
    • Web & App Activity
    • Location History
    • YouTube History (if you don't mind losing recommendations)

Step 2: Phone-Level Settings

  1. Settings → Privacy → Permission manager
  2. Review Location, Camera, Microphone permissions
  3. Remove access for apps that don't need it
  4. Settings → Google → Ads → Reset advertising ID

iOS Privacy Essentials (5 Minutes)

Step 1: Apple Privacy Settings

  1. Settings → Privacy & Security → Tracking
  2. Turn off "Allow Apps to Request to Track"
  3. Settings → Privacy & Security → Location Services
  4. Review each app – set most to "While Using App" or "Never"

Step 2: Apple ID Settings

  1. Settings → [Your Name] → Media & Purchases → View Account
  2. Settings → Privacy & Security → Analytics & Improvements
  3. Turn off "Share iPhone Analytics"
  4. Settings → Siri & Search → Turn off "Listen for Hey Siri" if you don't use it

Facebook/Instagram Settings (The Big One)

Most Important Facebook Changes:

  1. Facebook.com → Settings & Privacy → Settings
  2. Click "Your Facebook Information" → "Off-Facebook Activity"
  3. Click "Clear History" and "Turn Off Future Activity"
  4. Go to "Ad Settings" → Turn off "Ads based on data from partners"
  5. "Ad Settings" → "Categories used to reach you" → Remove categories you don't want

Instagram (Same Company, Separate Settings):

  1. Instagram app → Profile → Settings → Ads
  2. Turn off "Ad Data" options
  3. Go to "Data Download" to see what Instagram has collected (often surprising)

When You Actually Need Physical Security

For most people, software settings are enough. But some situations require physical signal blocking:

Professional Scenarios:

  • Sensitive business meetings (legal, medical, corporate)
  • When handling confidential information
  • Government or defence work
  • High-value negotiations

Personal Scenarios:

  • Protecting car key fobs from relay attacks
  • International travel in surveillance-heavy countries
  • Complete digital detox periods
  • Preventing phone tracking during personal time

Practical Solution: A quality Faraday bag provides complete signal isolation when software settings aren't enough. Unlike complex privacy software, a Faraday bag works instantly and doesn't require technical knowledge.

Common Sense Privacy Rules

The 5 Rules That Actually Matter

Rule 1: Don't Install Apps You Don't Really Need
That flashlight app doesn't need access to your contacts. When in doubt, use your phone's built-in features instead of downloading separate apps.

Rule 2: Read Permission Requests
If a calculator app wants access to your camera and microphone, that's a red flag. Apps should only request permissions they actually need.

Rule 3: Use Your Phone's Built-in Privacy Features
Both Android and iOS have gotten much better at privacy controls. Use them instead of downloading third-party "privacy" apps.

Rule 4: Social Media is the Biggest Risk
Facebook, Instagram, TikTok, and similar apps collect far more data than your banking app. Focus your privacy efforts here.

Rule 5: When Software Isn't Enough, Go Physical
For truly sensitive situations, physical security (like signal-blocking bags) is more reliable than software settings.

For Families and Older Users

Keep It Simple Strategy:

  1. Start with one platform: Don't try to fix everything at once
  2. Focus on Facebook first: It's usually the biggest privacy concern
  3. Use the "less is more" approach: Fewer apps = fewer privacy concerns
  4. Regular check-ins: Review settings every few months, not daily

Helping Parents or Grandparents:

  • Offer to help with settings (don't just tell them what to do)
  • Show them how to spot suspicious apps before installing
  • Explain that free apps usually aren't actually "free"
  • Help them understand that privacy settings change – it's not "set and forget"

Red Flags for Any User:

  • Apps requesting excessive permissions
  • "Free" apps that seem too good to be true
  • Clicking on ads in apps or social media
  • Downloading apps from unknown sources

When You Need More Than Software Settings

Recognizing Physical Security Needs

Sometimes, changing privacy settings isn't enough. You need complete signal isolation:

Professional Situations:

  • Legal consultations (lawyer-client privilege)
  • Medical consultations (patient privacy)
  • Business negotiations (competitive intelligence protection)
  • Government work (classified information)
  • Corporate board meetings (insider information)

Personal Situations:

  • Protecting car keys from relay attacks (modern car theft method)
  • International travel (avoiding foreign surveillance)
  • Complete digital detox periods
  • High-value personal meetings
