Cynia — Email Shield

HOW IT WORKS Once installed, Cynia silently scans your Gmail inbox every time you open it. Each email gets a risk badge: ✓ Safe — No threats detected ⚠ Suspicious — Proceed with caution ✕ Dangerous — Do not click any links WHAT MAKES CYNIA DIFFERENT Most security tools protect your device after something bad happens. Cynia stops threats before you open the email — at the decision layer, not the execution layer.
