• 🔍 Satsify detects prices on Amazon pages using specialized selectors
• 🎯 It handles various Amazon price formats including:
  • Regular product prices
  • Deal prices
  • Price ranges
  • "List Price" and "Sale Price"
• 🧮 Converts prices to satoshis using the formula: sats = usd_amount * 100,000,000 / btc_price_in_usd
• 🔄 Replaces the original USD text with the satoshi amount, formatted for readability
• 🔒 Preserves Amazon's page functionality while providing Bitcoin-native prices

🔒 Privacy & Permissions

Satsify requires minimal permissions:

• activeTab: To detect and convert prices on Amazon pages
• storage: To save your preferences and Bitcoin price data
• *://*.amazon.com/*: To operate on Amazon domains

The extension doesn't collect any personal data or browsing history.
