What is the main difference between website tracking and app tracking?

• A. Websites use cookies; apps use a software development kit, or SDK
• B. Websites use cookies; apps use a tag manager
• C. Websites use cookies; apps use a data layer
• D. Websites use cookies; apps use a browser fingerprint

Answer: (A)

The key idea is how data is collected in each environment. Websites rely on cookies—small text files stored in the browser that remember users, sessions, and interactions across pages. Apps, on the other hand, don’t have the same browser storage, so they use a software development kit (SDK) embedded in the app to collect events, user properties, and engagement data and send that information to analytics or advertising platforms. This SDK-based approach is the standard way apps track user activity. Other options aren’t the main mechanism: tag managers are primarily used to manage and deploy tags on websites, not the fundamental difference between how apps collect data. A data layer is a web concept used to pass structured data into tag managers on websites. Browser fingerprinting is a web-tracking technique based on browser properties, not a general model for app tracking.
