Open Lunar Defense and tap Run Security Scan on the home screen to start a sweep. It runs entirely on your device and finishes in seconds, no account or sign-in required.
No. You can download the app and run unlimited manual sweeps without an account. A Pro subscription is tied to your Apple ID, so there's still no separate account to manage.
Lunar Defense Mobile Security supports iPhone running iOS 26 or later.
A sweep runs three families of checks plus a final cross-check: device integrity (jailbreak traces, injected code, app isolation, and verifying your device is genuine with Apple), connection safety (proxies, interception, and impersonation), and a correlation step that weighs everything together. Tap any result to see what it checked and what it found.
When a sweep finds something, the app gives you a consolidated, ranked to-do list, safety-first steps first, and each step explains why it helps. Work through it top to bottom. If you're unsure how to proceed, email support@lunardefense.co with a description of what you saw and we'll help.
You can run a manual sweep any time, for free. With Pro, the app sweeps automatically in the background on a schedule and alerts you if something changes, so you don't have to remember.
Pro subscriptions are billed through your Apple ID and managed in iOS Settings:
You'll keep Pro until the end of your current billing period.
Pro is $4.99/month or $49.99/year. The yearly plan includes a 3-day free trial. Subscriptions auto-renew until cancelled.
The yearly plan starts with a 3-day free trial. You won't be charged if you cancel before the trial ends. If you don't cancel, the subscription begins automatically and your Apple ID is charged.
Sign in with the same Apple ID you used to subscribe, open the app, and tap Restore Purchases in Settings. Your Pro access will be reinstated.
Purchases are processed by Apple, so refunds are handled through Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, and request a refund for Lunar Defense. If you need help, email us and we'll point you in the right direction.
Your scan results and personal information never leave your device, and the analysis runs on-device. The app makes only a few network connections (verifying your device is genuine with Apple, checking the connection to us is secure, push for background scans, and payments through Apple), and none of them carry your scan results or personal information. See our Privacy Policy for full details.
The app is built to minimize data collection. Details of what is and isn't collected are described in our Privacy Policy.
