## Description

UsageX v2 is a privacy-focused browser extension designed to help you monitor and optimize your <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/cf6f55cbba6731f7030d49478c86cb1b6c503e9ea8cb3f1a019bd0e646726ebe/http%3A//Claude.ai" rel="nofollow">Claude.ai</a> usage limits directly on the page. All stats are calculated and stored locally on your device.

✨ Features:
• <strong>On-Page Sidebar:</strong> Renders a clean, responsive panel docked inside <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/cf6f55cbba6731f7030d49478c86cb1b6c503e9ea8cb3f1a019bd0e646726ebe/http%3A//Claude.ai" rel="nofollow">Claude.ai</a> (collapsible, resizable, or floats anywhere).
• <strong>Usage Gauges:</strong> Live percentage indicators for Claude's 5-hour and 7-day limits, calculated from official API responses.
• <strong>Token Burn Rate:</strong> Visual pulsing indicator showing your current prompt pace.
• <strong>Thinking Effort Breakdown:</strong> Tracks message counts per effort level (Low, Medium, High, Max) and estimates token usage.
• <strong>Usage Heatmap &amp; Sparklines:</strong> GitHub-style 30-day usage grid and 7-day sparkline charts for visual token trends.
• <strong>Multi-Account Support:</strong> Automatically detects account switching and segments stats per user.
• <strong>Custom Alert Sliders:</strong> Configure browser or toast notifications when usage thresholds are reached.
• <strong>Optional Feedback Form:</strong> Report issues or suggest features directly from the UI.

🔒 Privacy First:
UsageX stores 100% of your usage logs locally in IndexedDB. No third-party trackers, no telemetry. The only outbound network connection is the optional, user-initiated feedback form.
