Learn how to use, install, and secure PasteProof—the browser extension that prevents accidental PII and secrets from being pasted into web forms.

What is PasteProof?

PasteProof is a privacy-first, Manifest V3 compliant browser extension that provides real-time detection of sensitive data (PII) directly in your browser. It helps prevent accidental data leaks by warning you before you paste sensitive information into web forms.

All core PII detection happens locally in your browser. No data is sent to a server in the free version.
Performant
Uses a debounced scanning mechanism to ensure smooth performance without slowing down webpages.
Smart Detection
Intelligently recognizes input field types and skips unnecessary warnings for appropriate fields.
Cross-Browser
Full support for Chrome, Firefox, Edge, Brave, and other Chromium-based browsers.
