InvoiceGuard assigns each installation a randomly generated anonymous ID stored locally on your device. We do not collect your name or email address unless you upgrade to Pro (Stripe collects payment details directly).
Invoice email text you submit for extraction is sent to our API to parse invoice fields. We store structured invoice metadata (client name, amount, dates, status) linked to your anonymous ID.
