What Billflow does
Billflow is a bill tracking service that connects to your Gmail to automatically find and organize invoices, receipts, and payment confirmations. We use AI to extract bill details (vendor, amount, due date) so you don't have to enter them manually.
Data we collect
- Account info: Your name and email address via Google or Clerk sign-in.
- Gmail data: We read your emails to find bills and payment confirmations. We only access email content — we never send, delete, or modify emails.
- Extracted bill data: Vendor names, amounts, currencies, due dates, invoice numbers, and categories extracted from your emails.
- Payment info: Stripe handles all payment processing. We store your subscription status but never your card details.
How we use your data
- To scan your Gmail for bills and payment confirmations
- To extract and organize bill information using AI (Anthropic Claude)
- To show you dashboards, insights, and reminders about your bills
- To match payments to bills automatically
We do not sell, share, or use your data for advertising. Your financial data is yours.
