PasteGuard: Sensitive Data Shield per yasir_dev

Stop Shadow AI from leaking your sensitive data.

PasteGuard is a browser extension that sits between your clipboard and the webpage. When you paste text on a monitored site, PasteGuard automatically detects and masks sensitive data before it reaches the page.

Key Features:
- Automatic Detection: Built-in rules for IPv4/IPv6, API keys, AWS/GitHub tokens, and more.
- Reverse Mapping (BETA): Copying masked text back restores the original values to your clipboard locally.
- Remote Feeds: Subscribe to remote JSON URLs to sync security policies across your team.
- Custom Rules: Create your own regex or text-based filters.
- 100% Local: All processing happens in your browser. No data is ever sent to our servers.

Why PasteGuard?
Workers often use AI tools like ChatGPT or DeepSeek to analyze logs or code. Without protection, this can lead to "Shadow AI" data leaks. PasteGuard ensures your corporate secrets stay internal.
