Track Bitcoin prices, market data, and trends with a clean, lightweight dashboard

Sparrow BTC Dashboard is a lightweight, privacy-first browser extension that provides a clean Bitcoin (BTC) price overview and fiat converter directly inside your toolbar popup. Designed with a strict "Zero Permissions & Zero Network" architecture, this extension ensures complete user privacy by operating entirely locally without connecting to any external servers or APIs. Key Features: • Single Asset Focus: Dedicated exclusively to Bitcoin (BTC) market data, pricing, and trends. • Fiat Converter: Instantly convert BTC values to major world currencies (USD, EUR, GBP, JPY, and more). • 7-Day Sparkline Trend: View clean historical price trajectory graphs directly within the interface. • In-Popup Alerts: Set quick session-only target alerts right inside the popup menu. Privacy & Security Highlights: • Zero Chrome Permissions: Declares no browser API permissions and no host permissions whatsoever. • No Network Requests: Performs zero fetch(), XMLHttpRequest, or external API calls. All figures are bundled static demo data. • No Data Collection: Does not collect, store, track, log, or transmit any personal user information, cookies, or analytics. • No Persistent Storage: Uses no localStorage or chrome.storage; all data exists purely in RAM and disappears instantly when the popup closes.
