Apple promotes privacy, but many iPhone users both consumers and employees are unaware of how apps and publishers continue to track behaviour using a method called fingerprinting.
What Is Fingerprinting
Fingerprinting is a technique used by apps and websites to build a unique profile of your device without your permission. Unlike traditional tracking (like cookies), fingerprinting gathers data such as:
Device model and OS version
Language, time zone, and screen resolution
Installed fonts and browser settings
IP address and network behaviour
All this data creates a digital fingerprint that can identify and follow you across multiple apps and websites — even if you’ve opted out of tracking.
Why It Matters for Individuals and Businesses
For consumers, fingerprinting on iPhones means private information can be used to serve targeted ads, influence content, or be sold to data brokers.
For businesses, fingerprinting raises more serious concerns:
- Employees using personal apps on company devices may unintentionally leak data.
- BYOD policies can introduce fingerprinting-based tracking into corporate networks.
- Sensitive operational data could be inferred by third parties
