Frequently asked questions
Why do browsers restrict clipboard permissions?
Browsers restrict clipboard read access to prevent malicious websites from silently stealing sensitive data, such as passwords, personal identification, or payment details that you recently copied.
Can this test see the content stored in my clipboard?
The test only queries permission status and attempts authorized read operations within your browser sandbox. All checks run locally on your device, and no clipboard text is transmitted to external servers.
How do I change my clipboard permissions in Chrome or Edge?
Click the site settings icon located to the left of the browser address bar, locate the Clipboard section, and choose between Allow, Ask, or Block.
Why does writing to the clipboard often work without an explicit prompt?
Most browsers allow websites to write to the clipboard when triggered by a direct user interaction, such as clicking a copy button, while reserving strict permission prompts for reading clipboard data.
Is this clipboard permission test free to use?
Yes, this browser-based utility is completely free to use with no account signups or software installations required.
