  ⭐ Three favorite currencies, side by side
  Compare any price in up to three currencies at once, useful when you're deciding which regional store gives the better deal.
  
  🌍 130+ supported currencies
  Every major world currency plus regional ones that other converters often skip, including currencies from Central and Eastern Europe, the Caucasus, Southeast Asia, Africa and Latin America.

  🆚 WHY CNVRT
  ━━━━━━━━━━━━━━━━━━━━━━━━
  Many currency converter extensions are slow, ad-supported, or quietly collect browsing data. CNVRT is different:
  ✅ Free forever. No premium tier, no upsells.
  ✅ No account required.
  ✅ No tracking, no analytics, no ads.
  ✅ All settings stored locally on your device.
  ✅ Tiny footprint, instant tooltips, clean dark UI.
  ✅ Independent developer, direct support.
  
  ━━━━━━━━━━━━━━━━━━━━━━━━
  🔒 PRIVACY
  ━━━━━━━━━━━━━━━━━━━━━━━━
  CNVRT does not collect, transmit or sell any personal data. The extension only fetches exchange-rate JSON files from public APIs. No page content, no URLs, no user identifiers ever leave your browser. Full privacy policy on the homepage.
  
  ━━━━━━━━━━━━━━━━━━━━━━━━
