  description

  SubTrack helps you see what you’re paying for by finding subscription and billing emails directly in Gmail.
  
  HOW IT WORKS
  • Open Gmail in a tab and run a scan from the extension.
  • SubTrack looks for subscription-related messages in your inbox.
  • Your first full pass covers roughly the last 12 months; later scans focus on newer mail.
  • Connect with your SubTrack API key to send findings to your dashboard.
  
  WHY SUBTRACK
  • No Gmail API setup—scanning runs in your browser while you use Gmail.
  • Built for recurring charges, trials, and renewal notices you might forget.
  • Pairs with the SubTrack web app for a clearer view of spend over time.
  
  PERMISSIONS
  The extension needs access to mail.google.com to read page content during a scan, identity for Google sign-in where applicable, and the SubTrack API host to sync data when you connect your account.
  
  PRIVACY
  Scans run in your Gmail tab; review the SubTrack privacy policy on the official site for how synced data is handled.
