You were talking about buying a new washing machine with your mother. You didn't search for it. You didn't text about it. But 20 minutes later, your Instagram shows an ad for washing machines. Coincidence? Let's talk about what's really happening.
Is Your Phone Actually Listening to You?
The short answer: probably not in the way you think. The longer answer is more unsettling.
Major companies like Google and Apple have repeatedly denied that their devices continuously listen to conversations for advertising purposes. And technically, constantly recording and transmitting audio would drain your battery noticeably and consume enormous amounts of data.
But here's what IS happening — and it's arguably worse.
What's Actually Going On
1. Your phone tracks your location — always
You visited a washing machine showroom last week. You didn't buy anything. But your phone recorded that you spent 22 minutes at that location. That data was sold to advertisers. They now know you're in the market.
2. Your search patterns reveal everything
You searched "best washing machines under 30000" three days ago. You forgot about it. The advertising system didn't. It's been waiting for the right moment to show you an ad — and it chose the moment right after your conversation with your mother because you just picked up your phone.
3. The people around you are tracked too
Your mother searched for washing machines on her phone. Your phones were in the same location (your house). Advertising networks connected the dots: people who live together share purchasing decisions. So her searches triggered your ads.
4. Apps have more access than you realise
That free flashlight app you downloaded? It asked for microphone access. That food delivery app? It has access to your contacts. Every permission you grant is a window into your life that someone is profiting from.
The Real Truth
Your phone doesn't need to listen to your conversations. It already knows so much about you from your location, searches, app usage, purchases, and social connections that it can predict what you'll want before you say it out loud.
What To Do About It — Step by Step
Step 1: Audit app permissions (5 minutes)
On Android: Settings → Apps → select each app → Permissions. Remove microphone, camera, and location access from any app that doesn't absolutely need it.
On iPhone: Settings → Privacy & Security → review each category (Microphone, Camera, Location). Be ruthless.
Step 2: Turn off ad personalisation
On Android: Settings → Google → Ads → "Delete advertising ID"
On iPhone: Settings → Privacy → Apple Advertising → Turn off "Personalised Ads"
Step 3: Disable "Hey Google" and "Hey Siri" always-on listening
If your phone is waiting for a wake word, it IS listening — just for that specific phrase. But the audio buffer can capture nearby conversation.
On Android: Google App → Settings → Voice → "Hey Google" → Turn off
On iPhone: Settings → Siri & Search → Turn off "Listen for Hey Siri"
Step 4: Review location sharing
Set location access to "While Using" instead of "Always" for every app. Better yet, turn it off completely for apps that don't need it. A calculator app doesn't need your location.
Step 5: Use a private browser
Switch to Firefox or Brave for daily browsing. Use DuckDuckGo instead of Google for searches you don't want tracked. Your search history is the single most valuable dataset advertisers have about you.
For Aunties and Parents
If this sounds complicated, start with just one thing: go to Settings → Apps → and check which apps have microphone access. Remove it from anything that isn't a phone call or video call app. That alone makes a significant difference.
The Bigger Picture
You are not the customer of free apps. You are the product. Every "free" service — social media, email, maps, games — makes money by collecting and selling your data. That's the business model.
This doesn't mean you need to throw away your phone. It means you need to understand the trade-off and make informed choices about what you share. Awareness is the first line of defense.
And that's exactly what DHEDPED is here for.
