Privacy Policy & Data Security

At GST-Hawk (www.gsthawk.com), protecting the confidentiality of your financial records, invoice registers, and client data is our highest engineering priority.

1. 100% In-Browser Client-Side Processing Architecture

GST-Hawk is engineered with a strict Zero-Storage Security Model. When you upload Purchase Registers or GSTR-2B files (Excel, CSV, JSON):

• The mathematical comparison, fuzzy invoice matching, and 19-sheet Excel workbook generation execute locally in your browser's memory (Web Workers / SheetJS engine).
• Your sensitive financial invoice numbers, supplier names, taxable values, and GST figures are NEVER saved, written to disk, or stored in any database on our cloud servers.
• Once you close or refresh your browser tab, all transient invoice memory is permanently wiped.

2. Information We Collect

We only collect the minimal information necessary to maintain your account and subscription:

• Account Profile: Your name and verified email address via Google OAuth (to manage subscription activation).
• Billing Telemetry: Transaction ID, plan tier, and payment timestamp (handled securely by authorized payment partners: Razorpay / Cashfree). We never store your Credit/Debit Card numbers, UPI PINs, or CVV.

3. Contact Regarding Privacy
