Analytics / Logging SDK

"Design a drop-in analytics SDK like Amplitude or Mixpanel."

Analyzing the Problem

Amplitude and Mixpanel are drop-in analytics SDKs: the host app fires events from anywhere in its code, the SDK records them on disk, batches them, and uploads to a warehouse in the background. It captures track(name, properties) calls, persists them before acknowledging the caller, batches on size and age, uploads through WorkManager with backoff, scrubs PII at write time, and honors an opt-out that stops capture and schedules a server-side delete. Only the client SDK is in frame; the warehouse and console are not.
