CLOKR — AI Privacy Shield

Masks sensitive data (emails, IBANs, tax codes, cards) before reaching AI chatbots. 100% local processing.

CLOKR — AI Privacy Shield is a Chrome extension that helps protect your privacy when using AI chat tools. It detects sensitive data patterns in what you type and replaces them with secure placeholders before the message is sent to external servers (example: mario.rossi@gmail.com → [EMAIL_1]). This helps reduce the risk of accidentally sharing personal information. Works with popular AI chat platforms. Protected data types (with advanced algorithmic validation): Email addresses Phone numbers Italian tax codes (Codice Fiscale - verified via checksum) IBAN numbers (verified via MOD-97) Credit Cards (verified via Luhn algorithm) IP Addresses (IPv4 & IPv6) Dates of Birth Italian Health Cards (Tessera Sanitaria) Key points: Local processing in your browser No telemetry and no data collection Open source: https://github.com/progetticyber/clokr-extension What's new in v2.1.1: Improved reliability of detection and masking across all supported platforms. After you install it, you can keep chatting normally while CLOKR masks sensitive details in real time. CLOKR is an independent, open-source project and is not affiliated with, endorsed by, or sponsored by any third-party AI provider.
