About this extension
Time Tracker - Web Habit Builder is a free, privacy-first web habit builder that automatically logs screen time, provides accurate analytics, and blocks distracting sites — keeping all data strictly local and under your control. 🚀

🌟 CORE CAPABILITIES

⏱️ Track and Audit Time: Automatically monitor active web usage with a high-accuracy engine. No account required. It ensures every second is correctly recorded for a truthful view of your screen time.

📊 Analyze Digital Habits: Gain deep insights through multidimensional reports. Visualize productivity by Site, Category, or Tab Group. Works fully offline with zero data leakage.

🛡️ Block Addictive Sites: Reclaim your focus with an integrated website blocker. Set flexible time limits and rules to break addictive browsing cycles and maximize deep work.

🔍 Precision "Virtual Sites": Beyond domain tracking, define specific sub-page URLs (like a YouTube video or Notion doc) for granular monitoring once configured.

🔒 DATA OWNERSHIP AND TRANSPARENCY

🏠 Local-Only Storage: 100% of your history stays on your machine. The extension does not collect, store, or transmit your data to any remote servers.

☁️ User-Controlled Sync: You have the option to sync across devices using your own WebDAV, GitHub Gist, or Obsidian accounts. These connections are entirely managed and authorized by you.

⚖️ MIT Licensed: Transparent and audit-ready code under the MIT License. No hidden tracking, no subscriptions.

🔄 SEAMLESS TRANSITION

📥 One-Click Import: Easily migrate from Webtime Tracker or Web Activity Time Tracker without losing your history.
💻 Cross-Browser: Native support for Chrome, Firefox, and Edge with automatic Dark Mode.
