📌 Is it true that phones spy on us?

📢 Short answer: Yes and no.

Big tech doesn't need to listen to your conversations , because they have other, more advanced methods of tracking your behavior.

🔍 Methods they use to collect your information:

Browsing history → Google tracks every search and page you visit.
Real-time location → Your phone monitors where you are at all times.
App permissions → Many apps access your microphone, contacts, and photos without you even realizing it.
Social networks → Facebook, Instagram, and TikTok analyze your activity, even outside the app.
Connection between devices → If you use the same Wi-Fi on multiple devices, your activity is synced .

⚠️ Key Fact: In 2019, it was leaked that Facebook was analyzing users' audio recordings to improve its artificial intelligence. Google and Apple have also been accused of the same.

📌 How they collect your information without you realizing it

Data is extracted in a variety of ways. Here are the main ones:

🔹 Cookies and trackers : Websites leave small files in your browser to record what you do.
🔹 Apps with excessive permissions : Apps like TikTok and Facebook ask for access to your microphone, camera, and location .
🔹 Public Wi-Fi : Unencrypted networks allow third parties to capture data from your phone.
🔹 Predictive AI : Based on your past activity, algorithms predict what you'll search for .

💡 Conclusion: They don't need to listen to you, because they already know what you're going to do before you even think about it.

📌 How to prevent your data from being tracked

If you want to improve your digital privacy, follow these steps:

1️⃣ Check your apps' permissions 🔎

📌 On Android:
🔹 Go to SettingsPrivacyPermission Management . 🔹 Revoke microphone, location, and storage
access from suspicious apps.

📌 On iPhone:
🔹 Go to SettingsPrivacy & Security .
🔹 Review the apps that access Microphone, Camera, and Location .

2️⃣ Use private browsers and search engines 🕵️‍♂️

Google tracks all your searches. To avoid this, use these:

🔹 Safe search engines:
DuckDuckGo → Doesn't save your search history.
Brave Search → Doesn't track or sell your information.

🔹 Private Browsers:
Brave Browser → Block ads and trackers automatically.
Tor Browser → Hide your identity on the web.

3️⃣ Disable ad personalization 📢

📌 On Google:
1️⃣ Go to myaccount.google.com
2️⃣ Go to Data & Privacy .
3️⃣ Turn off Ad Personalization .

📌 On Facebook:
1️⃣ Go to Settings & Privacy .
2️⃣ Go to Ads Preferences .
3️⃣ Turn off Ads based on off-Facebook activity .

📌 The best tools to protect your privacy

If you want maximum security , here are the best tools:

🔹 VPNs (to hide your location)

NordVPN → Advanced protection with servers around the world.
ExpressVPN → High speed and no activity logs.
ProtonVPN → Free plan with good privacy measures.

💡 Important: Not all VPNs are safe. Avoid unknown free ones , as many sell your data.

🔹 Password managers (to prevent hacking)

Bitwarden → Secure, open source, and free plan.
1Password → Extra protection with advanced authentication.
Dashlane → Military-grade encryption for added security.

🔹 Secure browsers

Brave → Ad-free and privacy built in.
Firefox Focus → Automatically blocks trackers.

Frequently Asked Questions

❓ 1. How do I know if my phone is listening to me?

There is no concrete evidence that phones listen to conversations in real time. However, apps and social networks analyse your digital behaviour (searches, interactions and location) to predict what you might be interested in buying or viewing.

💡 Tip: Review microphone permissions in your apps and limit access to non-essential ones.

❓ 2. Is it safe to use a free VPN to protect my privacy?

It depends. Many free VPNs sell your information to third parties , putting your privacy at risk rather than protecting it.

Recommended VPNs: NordVPN, ExpressVPN, and ProtonVPN (which has a reliable free plan).

❓ 3. How do I prevent Google from tracking my searches?

Google tracks all searches and websites visited to personalize ads. To prevent this:

🔹 Use a private search engine like DuckDuckGo or Brave Search.
🔹 Disable activity history on your Google account.
🔹 Browse in incognito mode , although this does not hide your IP.

💡 Pro tip: Switch your browser to Brave or Firefox Focus for added protection.

📌 Conclusion: Privacy is your right

Yes, big companies track your digital activity. But you have the control to protect your information .

Review your app permissions.
Use private browsers and search engines.
Disable ad personalization.
Use VPNs and password managers.

⚠️ Remember: Privacy is a right. Don't let your information be sold without your consent.
