## Overview

MyTask is an Android academic planner for managing courses, tasks and class schedules, with calendar/dashboard views, reminders, account-based cloud sync, templates and backup/restore. The main entry point gates access to the workspace and coordinates account sync; feature screens provide the planning workflow, while repositories connect it to local and cloud state. The README is only a one-line product description, and several feature implementations were not sampled, so uncertain internal wiring is omitted.

Main entry points: [`app/src/main/java/com/mytask/navigation/NavGraph.kt`](https://github.com/xygritte/mytask-academic-planer-app/blob/main/app/src/main/java/com/mytask/navigation/NavGraph.kt) (Navigation), [`app/src/main/java/com/mytask/MainActivity.kt`](https://github.com/xygritte/mytask-academic-planer-app/blob/main/app/src/main/java/com/mytask/MainActivity.kt) (App entry), [`app/src/main/java/com/mytask/data/repository/FirebaseAuthRepository.kt`](https://github.com/xygritte/mytask-academic-planer-app/blob/main/app/src/main/java/com/mytask/data/repository/FirebaseAuthRepository.kt) (Firebase auth), [`app/src/main/java/com/mytask/data/repository/CloudDataSyncRepositoryEntityMerge.kt`](https://github.com/xygritte/mytask-academic-planer-app/blob/main/app/src/main/java/com/mytask/data/repository/CloudDataSyncRepositoryEntityMerge.kt) (Cloud data sync)
