TimeTracker is a minimalist, fully automated productivity extension that helps you understand where your time goes online.

How often do you lose track of time while surfing the web or watching YouTube videos? TimeTracker quietly runs in the background and builds an intuitive dashboard of your daily, weekly, and yearly browsing habits.

Key Features:

Automated Tracking: No need to manually start or stop timers. TimeTracker intelligently monitors your active tabs and calculates your usage down to the minute.
Smart Media Detection: The timer pauses when you step away from your computer, but it will automatically keep tracking if you are actively listening to music or watching a video in a background tab!
Beautiful Dashboard: Open the extension popup for a quick glance at your Top 5 websites, or expand it into a full-page view to see a scrollable list of every site you've visited alongside a sleek visual chart.
Data Export & Import: You own your data. Backup your long-term tracking history locally to a JSON file at any time.
100% Privacy First: Everything is stored securely in your browser's local storage. Not a single byte of your browsing data is ever sent to the cloud or any external server.
