InfoShield prevents costly mistakes in real time by scanning what you paste or type into web forms — fully on your device, without sending any text to a server.
What it detects:
Personal information: national IDs (including checksum‑validated formats), passports and common global ID patterns
Payment data: credit cards (Luhn, 13–19 digits); IBAN as a soft warning
Developer secrets: API keys/tokens, JWTs and private keys
Soft signals: one‑time codes (OTP) and phone numbers (local and international)
How it works:
Continue, Redact & continue, or Cancel
“Don’t ask again on this site” and an Ignore list you control
Password/OTP fields are ignored automatically
Privacy by design:
100% on‑device detection; no form contents leave your browser
Minimal permissions (Manifest V3)
Built for:
Professionals handling IDs/PCI
Developers who copy/paste secrets
Anyone who wants a simple on‑device safety layer
