## Overview

TODU is a Flutter student productivity app. The documented user journey is to enter as a guest or authenticate locally, then manage notes and daily tasks, use a Pomodoro timer, and review study activity in analytics. Hive provides local persistence and user isolation; users can also export or restore notes and tasks. The repository tree contains no application source files, so paths and internal call ownership cannot be verified; relationships below reflect only capabilities and data flows explicitly described in the README.
