## Technical Notes

### Reliable Timer Persistence

Browser timers often lose accuracy when a tab becomes inactive, the page is refreshed, or the device goes to sleep.

Instead of relying on interval counts, TaskFlow stores timestamps and calculates elapsed time from the current clock whenever the timer updates. This keeps timers accurate even after long periods of inactivity.

### Daily Analytics Tracking

A task can run across multiple days, which makes analytics more difficult than simply storing a total duration.

To solve this, the application maintains a separate daily time store in localStorage. Each timer update only records the newly elapsed time for the current day, allowing the analytics dashboard to display accurate daily productivity data.

## Future Ideas

- Cloud sync across devices
- Team workspaces and shared task boards
- Recurring tasks and scheduled templates
- Progressive Web App support
