Fictional blocked-write preview

This page shows the shape of a PasteSentry warning before installation. It does not access, send, or store your clipboard.

Suspicious website clipboard write blocked
The intercepted text matched multiple command-risk signals.

Fictional event detail

PowerShell -EncodedCommand [redacted fictional sample]

The sample above is incomplete, inert text and is never executed. PasteSentry would leave the previous clipboard value unchanged when it blocks a supported website write.

Coverage boundary

PasteSentry checks supported website clipboard APIs after an explicit page write. It cannot inspect text copied manually, content written by other apps, or commands already pasted or run. It is preventive browser protection, not antivirus.

Private by design

Clipboard contents never leave your browser. PasteSentry has no product analytics, account, or cloud clipboard processing.
