About BillSensor

BillSensor is for freelancers, solopreneurs, and small businesses who pay for multiple SaaS tools and keep getting caught by renewal charges they didn't see coming. It works passively in the background while you browse Gmail — no Gmail login, no bank connection, no setup required.

What it does

  • Detects billing emails from 62+ SaaS tools automatically
  • Alerts you 7 days before a renewal charge via Chrome notification
  • Shows a dark pattern score for every detected tool — how hard they make it to cancel
  • Provides a direct cancel link for every subscription it finds
  • Generates cancellation records in PDF format (Pro)
  • Sends email renewal alerts so you're notified even when Gmail isn't open (Pro)

What it doesn't do

  • It does not connect to your Gmail account via OAuth
  • It does not access your bank account or card
  • It does not send your email data anywhere — everything stays in your browser
  • It does not require an account to start working
