Lockdown scans every app on your Android phone for spyware and stalkerware, shows you which apps are accessing your mic or camera right now, and checks your Wi-Fi for threats — in under 30 seconds.
Free · No account · Scan in 30 seconds
We ran Lockdown on a standard Android device — no suspicious apps installed, just the usual social media and shopping. Here's what the spyware scanner flagged.
Six protection layers working together — spyware detection, live sensor monitoring, Wi-Fi threat scanning, DNS inspection, and more.
Detects 70+ known spyware and stalkerware packages by signature, flags suspicious permission combinations, Device Administrator abuse, sideloaded APKs, and known surveillance app patterns. Results in under 30 seconds.
Real-time alerts the instant any app accesses your microphone or camera — even when running in the background with the screen off. Uses Android's AppOps API, not guesswork.
Detects open networks, DNS hijacking, rogue hotspots, weak encryption (WEP/WPA), and captive portal risks on your current Wi-Fi connection. Know before you connect.
See every permission every app holds, grouped by risk level. Instantly spot which apps have access to your location, contacts, or camera — and whether they actually need it.
Inspects DNS queries leaving your device and flags connections to known malicious or tracking domains in real time. Runs locally — your traffic never leaves your phone.
Lock Lockdown itself behind PIN or biometrics so nobody can tamper with your security settings or read your scan history. Works with fingerprint and face unlock.
Free, no account required. Install in seconds — no signup, no email address, no tracking.
Hit the scan button. Lockdown checks every installed app against its spyware and stalkerware database.
See your full results in under 30 seconds — flagged apps, risk levels, and what to do about each one. Everything stays on your phone.

We make money from subscriptions, not advertising or data brokering. Your data has no commercial value to us — by design.
Every permission we request is explained in plain English in our Privacy Policy. No surprises, ever.
The Network Monitor uses a VPN that runs entirely on your device. Your traffic is never routed through our servers or any third party.
The only data we ever send externally is anonymous crash reports — no personal data, no scan results, no app lists. Ever.
Yes. Lockdown's spyware scanner checks for 70+ known stalkerware and surveillance app packages, flags Device Administrator abuse (a common stalkerware technique), detects apps installed from outside the Play Store, and identifies dangerous permission combinations used by monitoring software.
Lockdown's Sensor Watch shows you in real time — including when your screen is off. It uses Android's AppOps system to log every mic and camera access event, which app triggered it, and when. You'll get an immediate alert whenever any app activates your microphone or camera.
No. Every scan runs entirely on your Android device. The only data that ever leaves your phone is anonymous crash reports via Firebase Crashlytics — no personal information, no scan results, no list of installed apps.
The Network Monitor uses a local VPN to inspect DNS queries — the requests your phone makes to look up website addresses. This VPN runs entirely on your Android device and does not route your traffic through any external server. Your internet connection is not affected; only DNS lookups are inspected.
No. Lockdown never accesses your mic or camera. Sensor Watch detects when other apps are using them by reading Android's AppOps system — it monitors access without needing those permissions itself. You can verify this in Android Settings → Apps → Lockdown → Permissions.
Lockdown requires Android 8.0 (Oreo) or higher. It works on Android 8 through 14 and supports all major Android manufacturers including Samsung, Google Pixel, OnePlus, and Xiaomi.
The core spyware scanner, permission audit, and Wi-Fi scan are completely free with no time limit. Premium adds real-time mic and camera monitoring (Sensor Watch), DNS Network Monitor, the Account Checker, scheduled automatic scans, PDF report exports, and App Lock with biometric authentication.
Subscriptions are managed through Google Play. To cancel: open the Play Store → tap your profile → Payments & subscriptions → Subscriptions → Lockdown → Cancel subscription. You keep Premium access until the end of your current billing period.
