PasteGuard

Your clipboard knows too much.

Every time you copy something, it stays. A password, an API key, a credit card number. Sitting on your clipboard, waiting for the wrong app to read it or the wrong moment to expose it. PasteGuard clears it before that moment arrives.

Six types of sensitive content. Caught before they become a problem.

Passwords

Copied from your password manager and forgotten. Still sitting on your clipboard an hour later when you switch apps.

Credit Card Numbers

Install once. Protected from that moment on.

Install and launch

PasteGuard installs in seconds via PKG installer. On first launch it moves to your menu bar and stays there.

Set your timer

Choose how long clipboard content should live before it is cleared. Set it once. Change it any time from the menu bar.

Enable detection

Turn on Sensitive Detection to receive a warning when a password, API key, or financial data lands on your clipboard.

Work normally

Copy and paste as you always have. PasteGuard handles the cleanup quietly in the background without interrupting your flow.
