Provides access to the host application's Ecto repo.

GoodAnalytics doesn't define its own Ecto.Repo — it borrows the host application's repo at runtime. Context modules call repo() directly:

GoodAnalytics.Repo.repo().all(query)
GoodAnalytics.Repo.repo().insert(changeset)

Configure via:

config :good_analytics, repo: MyApp.Repo
