Screen Time Analyzer Module integrates psutil process monitoring, window focus detection, and system time to build a comprehensive application usage tracking pipeline. Data flows from input sources through an Application Usage Tracker and Time Aggregator, generating daily and weekly summaries while a Behavior Pattern Analyzer identifies usage trends. Aggregated metrics and behavior insights persist to SQLite, powering usage reports, UI charts, and external personalization engines. This modular architecture separates concerns across input collection, time-series aggregation, pattern analysis, and multi-channel output.
