How does Privacy Sheriff detect malicious extensions?

Privacy Sheriff analyzes the permissions and source code of your installed extensions locally to identify patterns common in keyloggers, session hijackers, and AI chat scrapers.

Is my data safe with Privacy Sheriff?

Yes. Privacy Sheriff is a local-only tool. It does not use any external servers, does not have telemetry, and never uploads your scan results. Your privacy audit remains entirely on your machine.
