  GrowIt is the simple, non-judgmental browser extension that shows you the true opportunity cost of your shopping cart. It transforms the way you see prices by showing you what that money could grow into if it were invested instead—right on the product page.
  
  How it Works
  Install in seconds: No account, no signup, no bank logins.
  
  Shop like normal: Browse your favorite sites like Amazon, Best Buy, and IKEA.
  
  See the real cost: A sleek, minimal widget appears automatically, showing you the 10, 20, and 30-year growth potential of that purchase.
  
  Features for the Mindful Shopper
  One-Time vs. Monthly: Buying a $350 pair of headphones? See the lump-sum growth. Buying a $20 coffee subscription? Switch to "Monthly" to see the power of recurring compounding.
  
  Smart Defaults: GrowIt uses an 8% historical S&P 500 average to give you realistic insights, but it’s fully adjustable to your preferred ROI.
  
  Zero Friction: It runs quietly in the background and only appears where you need it.
  
  Privacy-First by Design
  As a developer-built tool, we take your data seriously:
  
  No Accounts: We don't want your email or your name.
  
  Local Processing: All calculations happen locally in your browser.
  
  Zero Data Collection: We don't track your history or see your bank accounts. We only see the price tag on the page you're already looking at.
  
  Why GrowIt?
  We aren't here to give you a guilt trip. We’re here to give you the information you didn't have. Whether you decide to click "Add to Cart" or "Start Investing," you’ll be making a conscious choice.
  
  Stop guessing. Start growing.
