Dagger Detection & Cloak Protection
Everything runs in your browser. No servers, no network calls, no data leaving your machine. What happens locally stays local.
No data leaves
Detection and protection happen entirely on your device.
Nothing to trust
No servers means no third parties with access to your data.
Nothing to breach
If we don't have it, it can't be leaked, sold, or subpoenaed.
