Core Syntax & Patterns
The Data Trade-off Principle
Convenience/Free Service <=> Personal Data
This pattern describes the common exchange in the digital world. Users get a 'free' service (like social media or a search engine), and in return, the company collects user data to sell ads or improve its products.
The Profiling Algorithm Pattern
Data Point A + Data Point B + ... => Inferred Profile
Algorithms combine multiple, seemingly harmless pieces of data to create a detailed profile about you. For example, your location data, search history, and 'liked' posts can be used to infer your interests, income level, and political views.
The Consent Pattern
Action -> Request for Consent -> Data Collection
Websites and apps are often required to ask for your permi...
