What are the main types of mobile trackers, and how do iOS and Android differ in controlling them?
Advertising/marketing trackers (using IDFA/AAID for cross-app profiling) and analytics/performance trackers; iOS enforces strict technical controls via App Tracking Transparency, while Android relies mainly on disclosure.
* Mobile tracker types and the iOS vs Android control models. *
Two functional categories:
| Type | Function | Data collected |
|---|---|---|
| Advertising & Marketing | Audience segmentation, conversion tracking, cross-app profiling | IDFA (Identifier for Advertisers) / AAID (Google Advertising ID), usage patterns, purchase behaviour |
| Analytics & Performance | App monitoring, UX optimization, business intelligence | Screen views, clicks, session duration, crashes, device metrics |
iOS vs Android:
- iOS — App Tracking Transparency (ATT) enforces stricter technical controls (apps must ask permission to track)
- Android — relies primarily on disclosure-based approaches
Legal note: iOS apps are DRM-protected; reverse-engineering them can carry up to 5 years prison and $500,000 fines (17 U.S.C. §1204, DMCA). Static analysis is therefore only legally practical for Android APKs.
