Can websites really read my clipboard?

Yes, but modern browsers require a user gesture first. Older browsers may allow silent reads.

How can I protect against clipboard snooping?

Use a password manager that clears the clipboard after a few seconds. Avoid copying sensitive data with browser tabs open.

Does this demo send data anywhere?

No. All reading and analysis happens locally.

Do mobile browsers allow clipboard access?

Mobile browsers have stricter controls. iOS Safari and Chrome on Android may not support the API at all.
