Pharoah Mobile Shield

Pharoah Mobile Shield watches the mobile network around you for patterns consistent with a hostile environment — rogue base stations, forced 2G downgrades — and audits your installed apps for stalkerware, so you know what to harden before you travel.

WHAT IT DOES
• Live 2G downgrade detection: an observed drop from 4G/5G to 2G on your current operator.
• Anomalous attach: 2G on an operator that has only ever served you 4G/5G, learned from a local baseline.
• Unknown serving tower in a well-known area, tower churn while you are stationary, implausible signal jumps, and cell-identity inconsistencies — each weighted by how much it can honestly be trusted.
• Travel mode for when you are somewhere new and the baseline does not apply.
• Stalkerware audit of installed apps, on the phone.
• Runs as a foreground service so it can watch while the screen is off and notify you.

READ THIS BEFORE YOU TRUST IT
No unprivileged Android app can prove an IMSI-catcher is present, and any app that says it can is misleading you. The strongest tells — encryption switched off, silent SMS, identity requests — live in the baseband and Android does not expose them. Mobile Shield watches only the things the OS will tell it and flags patterns; a Normal verdict means "nothing I can see is wrong", and the app prints the full list of what it cannot see.

PRIVACY
Everything runs on the device. No account, no analytics, no advertising, no third-party SDKs, no network access at all. It never reads or handles your IMSI or IMEI. The tower baseline it learns stays in the app's private storage and is deleted when you uninstall.
