Analytics and Observability

Goal​

The client collects product analytics for the main user flows and statistics screens. The goal is meaningful usage visibility, not raw event spam.

Main pieces​

  • a shared AnalyticsTracker contract in commonMain;
  • a composite tracker that fans out to multiple providers;
  • debug logging for local visibility;
  • production integrations such as PostHog and Firebase.

Key rules​

  • avoid duplicate screen events from platform auto-tracking;
  • avoid sensitive user data in payloads;
  • avoid tying analytics to frequent Compose recomposition;
  • emit events that can be interpreted product-wise later.
