Read-only · local · open source
Check your phone's security.
Download MobileCheck to your computer, plug your phone in with a USB cable, and run a read-only scan: spyware indicators, stalkerware, risky settings. On iPhone it uses Amnesty's MVT against Citizen Lab and Amnesty indicators. Everything runs on your computer; nothing is sent unless you choose to.

Read-only
It observes and reports. It never changes your settings or touches your files.
Local & private
The scan runs on your device. No account, no upload, no telemetry.
Plain-language report
A health score and the top things to fix first, each with clear steps.
Track your progress
An encrypted local history shows whether your security is improving over time.
Reports in EN / ES / DE
Download a printable PDF report in English, Spanish, or German.
Optional encrypted sharing
Help the C-LAB research network with an encrypted file, only if you choose. Spyware findings are never in a routine export.
What it finds
- Mercenary-spyware indicators on iPhone (Pegasus, Predator) via Amnesty's MVT, and commercial stalkerware on Android.
- Accessibility services, notification listeners, device-admin apps, proxies, forced VPNs, risky certificates and profiles.
- Stale security patches, verified boot, jailbreak / root, and a clear, prioritized list of fixes.
What it is not
- Not a forensic tool. It is a fast triage; court-grade evidence needs a full acquisition.
- A clean result is NOT proof of safety. Advanced zero-click spyware may leave no USB-visible trace.
- Not a data collector. The temporary iPhone backup is deleted when done; your messages and photos are never uploaded.
