Clipboard Guard
Free Chrome extension that blocks websites from reading your clipboard without permission. Get notified and approve or deny clipboard access per site.
Some websites read your clipboard without asking. If you've copied a password, address, or anything private, that data can be silently accessed by page scripts. Clipboard Guard stops this. The extension injects a protective script before any page JavaScript runs, intercepting clipboard read attempts at the source. When a site tries to access your clipboard, Clipboard Guard blocks it and shows a toast notification. You can Allow Once for a single read or Always Allow to whitelist a trusted site. Manage your whitelist from the popup at any time. An activity log shows every blocked and allowed attempt. A red badge counts how many attempts have been blocked today. No data leaves your browser.

Frequently Asked Questions
Everything you need to know about Clipboard Guard.
How does it block clipboard reads?
add
It injects a script in the MAIN world (same context as page scripts) that overrides navigator.clipboard.readText and .read before any page JavaScript runs.
Can I allow specific sites?
add
Yes. When blocked, you can Allow Once or Always Allow. Always Allow adds the site to your whitelist, manageable from the popup.
Does it read my clipboard contents?
add
No. It intercepts the API call but never reads the clipboard data itself. It only blocks or allows the request.
