When you think about online tracking, cookies probably come to mind. But here’s the twist: mobile apps don’t use cookies. So how do they keep tabs on you? The answer lies in device identifiers, and they’re everywhere.
How Does Tracking in Mobile Apps Work?
Unlike websites, mobile apps can’t rely on traditional browser cookies to track your activity. Instead, they use unique identifiers built into your device. These identifiers allow advertising and analytics companies to monitor which apps you use, how often you use them, and even what you do inside those apps.
Two of the most common identifiers are:
- Apple iOS’s Identifier for Advertisers (IDFA)
- Google Android’s Advertising ID
These IDs act like a digital fingerprint for your device. They don’t reveal your name, but they create a profile based on your app usage, which advertisers use to target you with personalized ads.
Why Does This Matter?
Tracking isn’t just about ads. It can also raise privacy concerns:
- Behavior Profiling: Companies learn your habits, interests, and routines.
- Cross-App Tracking: Your activity in one app can influence ads in another.
- Data Sharing: Some apps share data with third parties, increasing exposure.
Even if you delete an app, the data collected while you used it may still exist.
Can You Stop It?
You can’t completely eliminate tracking, but you can reduce it:
- Reset Your Advertising ID: Both iOS and Android allow you to reset your identifier.
- Limit Ad Tracking: Enable “Limit Ad Tracking” on iOS or “Opt Out of Ads Personalization” on Android.
- Review App Permissions: Only grant permissions that are necessary.
- Use Privacy-Focused Apps: Choose apps that prioritize user privacy and transparency.
Mobile app tracking is subtle but powerful. Understanding how it works helps you take control of your privacy. A few quick settings changes can make a big difference in reducing unwanted tracking.
