What it does

ARK gives your phone a 0-100 security credit score, then runs targeted scans across device security, network exposure, app permissions, and breach exposure. Each scan ends with one-tap remediation deep-links. Privacy-first: on-device when possible, no analytics on free-tier scans. Shield tier adds dark-web monitoring, phishing scanner, Wi-Fi analyser, password health, DNS leak test, 2FA audit. Fortress adds GDPR autopilot, data-broker exposure, SDK X-Ray, AI decision rights, voice-clone risk.
