ClipGuard - Secret Leak Prevention

About

Never leak a secret by accident again.

ClipGuard detects API keys, tokens, passwords, webhooks, private keys, database connection strings, and other sensitive values when you paste them into a webpage. It warns you before the secret reaches a public issue, chat, forum, or form.

WHAT CLIPGUARD DETECTS

• AI API keys, including OpenAI, Anthropic, Google AI, and Hugging Face
• Cloud credentials, including AWS access keys
• GitHub and GitLab access tokens
• Stripe keys and webhook secrets
• Slack and Discord webhook URLs
• JWTs and private keys
• MongoDB, PostgreSQL, and Redis connection strings
• Password and credential assignments

HOW IT WORKS

1. ClipGuard checks paste events directly in your browser.
2. On high-risk sites such as GitHub, Slack, Discord, Stack Overflow, and Reddit, a detected secret is blocked and a warning is shown.
3. On other sites, ClipGuard displays a warning so you can review the text.
4. You can enable or disable protection and choose warning behavior from the extension popup.

PRIVATE BY DESIGN

• Detection happens entirely on your device.
• Pasted text is never transmitted to a server.
• No analytics, tracking, or account is required.
• Only settings and prevention statistics are stored locally in Chrome.

ClipGuard is a lightweight safety net for developers, maintainers, technical teams, and anyone who handles sensitive credentials in the browser.
