Description
A local checkpoint for sensitive information before it leaves your browser. PasteGuard helps prevent accidental exposure of sensitive information when submitting web forms. It scans supported form fields locally in your browser for payment card numbers, passwords, access tokens, private keys, JSON Web Tokens, and Singapore NRIC/FIN identifiers. If a potential risk is detected, PasteGuard warns you before submission and lets you cancel, mask supported values, continue once, or trust that website. Your form content is never uploaded or logged by PasteGuard. Detection happens entirely on your device, and no account is required.
