Ruja Guard

Protect sensitive text locally before you paste it into AI.

Ruja Guard is a private checkpoint between sensitive work and AI tools. Paste a prompt, email, note, contract excerpt or code snippet into the extension side panel, review the local findings, choose what to replace, and copy the protected result. Current capabilities: - local detection for email, validated IBAN and payment-card numbers; - bounded detection for bearer tokens, JWT-shaped values, assigned secrets and PEM private keys; - structural detection for Swedish personnummer and coordination numbers, Danish CPR candidates, and Lithuanian personal codes; - an encrypted private dictionary for client names, employees, codenames, cases, projects and product names; - stable, session-scoped placeholders and local restoration; - explicit Select all and Clear controls, plus a local exact-match action for values detection missed; - explicit clipboard write only after you choose Protect & copy or Copy sensitive result. Ruja Guard does not read pages, inject controls into AI sites, request general website access, read the clipboard, create an account, or send reviewed text to a Ruja server. Findings require your review; detection can miss sensitive values, so check the protected result before sending it elsewhere.
