Period Tracker

This is a starter Android app for tracking menstruation cycles. It is offline-only, uses local encrypted storage, and includes functional UI for logging, calendar, predictions, and reminders.

Features (MVP scaffolding)

• Cycle calendar with period/ovulation highlights
• Period start/end logging (stored locally) with delete support
• Ovulation window prediction
• Predictions for next cycle
• Daily reminders via WorkManager
• Offline-only data with encrypted Room database
• Dark mode support (follows system preference)
• Navigation icons in the bottom bar for intuitive tab switching

Recent improvements

• Dark mode: CycleTheme now respects the system dark/light preference
• Delete period logs: tap the trash icon next to any log entry to remove it
• Navigation bar icons: each tab now displays a meaningful Material icon
• Safer Room setup: fallbackToDestructiveMigration() prevents crashes on schema changes
• Code quality: replaced deprecated DayOfWeek.values() with DayOfWeek.entries; explicit 5L literal in period-length fallback; clearer require() error message in log input validation
• Calendar improvements: richer day styling, in-month analytics, and today highlighting
• Notification messaging: reminders now include symptom tracking prompts
• Offline backup/export: settings now provide a local JSON backup export flow

Next steps

• Add backup restore from exported JSON
• Add more customizable symptom templates
• Add trend charts for symptom and cycle history
