Seercode

Code without leaks.

Built for humans. Against the machine.™

Stop accidentally committing Aadhaar, PAN, UPI, API keys, and secrets to your repositories.

Seercode is a Visual Studio Code extension built specifically for Indian developers. It detects Indian PII (Personally Identifiable Information) and common secrets as you type, warning you before they ever reach GitHub.

Why Seercode?

Every Indian developer has accidentally pasted a real Aadhaar number into a test file. Every Indian engineer has hardcoded a UPI ID "just for now." Every Indian startup has leaked an API key to a public repo at some point.

Under the DPDP Act 2023, leaking customer PII can mean fines of up to ₹250 crore. The Information Technology Act 2000 and Bharatiya Nyaya Sanhita 2023 add criminal liability on top.

Seercode catches these mistakes at the source — in your editor — before they become incidents.

What it detects

Indian PII (Personal Data under DPDP Act 2023)

Aadhaar numbers — with Verhoeff checksum validation (drastically reduces false positives)
PAN cards — AAAAA9999A format with entity type recognition
UPI IDs — Recognizes 30+ Indian bank and payment app handles
Indian phone numbers — +91 mobile numbers (6-9 starting digit)
IFSC codes — Bank routing identifiers
Voter IDs — EPIC numbers
Indian passport numbers
Driving licence numbers — State/RTO/year/serial format

Generic Secrets (universal threats)

AWS Access Keys & Secret Keys
GitHub Personal Access Tokens (classic + fine-grained)
OpenAI API Keys
Anthropic API Keys
Stripe Live & Test Keys
Razorpay Keys
Slack Tokens
Google API Keys
JWT Tokens
Private Keys (RSA, EC, OpenSSH)
Database connection strings with credentials
Hardcoded passwords / API key assignments

`seercode.showStatusBar`	`true`	Show count in status bar

How false positives are minimized

Seercode is designed to be less annoying than alternatives:

Verhoeff checksum for Aadhaar — Random 12-digit numbers have ~10% chance of passing. Real Aadhaar always passes.
PAN structure validation — Position 4 must be a valid entity type letter (P/C/H/F/A/T/B/L/J/G).
Context boosts — A 12-digit number near the word "aadhaar" is more confident than one in isolation.
Known handle filtering for UPI — Only recognized banks/apps trigger.
Ignore patterns by default — Tests, mocks, fixtures, node_modules excluded.
Optional context requirement — Some detectors only fire WITH context (driving licence, passport).
