Lucia Cipher - hostile scan

just Luke

About this app

Lucia Cipher — Device Guard checks whether your phone is running in a hostile environment. One tap, a few seconds, and no data leaves your phone.

WHAT IT CHECKS

• Known root tooling — Magisk, SuperSU, KingRoot and other superuser managers and one-click root utilities
• Tampered system state — signs that the OS has been modified from its factory configuration
• Overlay-mount anomalies — filesystem tricks used to hide changes to system partitions
• Apps holding sensitive access — draw-over-other-apps permission, notification listeners, VPN services and device-admin receivers that could watch
or control your phone
• Unknown signatures — flagged apps are cross-checked against a list of trusted signing certificates so legitimate system apps aren't reported as
threats

HOW IT WORKS

• Tap Scan and get a graded verdict in seconds, with every finding explained and ranked by severity
• Review each finding and decide what to do — nothing is removed or changed without you
• Scan history is stored only on your device
• Optional Real-time protection keeps a continuous watch in the background and alerts you when something new appears

PRIVATE BY DESIGN

Scans run entirely on your device. Your apps, permissions and scan results are never uploaded, sold or shared. No account is required to scan.

BUILT FOR MANAGED DEVICES TOO

Device Guard is the free tier of Lucia Cipher, a device-management suite for organizations. If your organization enrolls this phone through its
companion app, Device Guard upgrades into the full suite — device administration, app management, lock screen and kiosk policies, and compliance
reporting. Until that happens, the management permissions listed on this app's store entry sit unused: they are reserved for the managed upgrade
and are only activated after enrollment, with a full in-app disclosure you must accept first.

If you just want the scanner, use it free — no enrollment needed.
