Deadline Countdown

Track deadlines, countdowns, priorities, notes, and browser reminders from a private local popup.

Deadline Countdown keeps your important due dates one click away in Chrome. Add tasks with deadlines, priorities, and optional notes, then watch live countdowns update directly in the extension popup. The extension is built for quick deadline checks during focused work: - Live countdowns for each active deadline - Priority levels for Low, Medium, High, and Critical tasks - Local browser notifications when a deadline is approaching - Search, status filters, and sorting by deadline, priority, name, or newest task - Edit, complete, reopen, and delete tasks - Clear completed tasks in one action - Import and export JSON backups - Local-only storage with no analytics, tracking, ads, or remote scripts Deadline Countdown stores task data on your device using Chrome extension storage. It does not send your deadlines, notes, or preferences to any external server.
