Clipboard Guard

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.
