Lockdown scans every app on your Android phone for spyware and stalkerware and checks your Wi-Fi for threats in under 30 seconds, then alerts you whenever your camera or mic turns on.
Free · No account · Scan in 30 seconds
No extra apps installed, just what ships on the phone. This is one real scan, word for word.
Six protection layers working together: spyware detection, camera and mic alerts, 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.
An alert the moment your camera or microphone switches on, naming the app that was open at the time. Android doesn't let regular apps identify background use, so for that it tells you it happened, not who.
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.

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's VPN runs on your device. DNS lookups are forwarded to Cloudflare's 1.1.1.1 resolver, and nothing is ever routed through our servers.
Crash reports go to Firebase Crashlytics with a random installation ID, and no name, scan results or app lists. No analytics, no ads, no tracking.
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.
Yes. Sensor Watch alerts you the moment your camera or microphone switches on, and keeps a log of every alert. If you allow Usage Access, each alert names the app that was open on screen at the time. Android doesn't let regular apps see which app is using the camera or mic from the background, so if something switches on while no app is open, Lockdown tells you it happened but can't name it.
Your scan results never leave your phone. The only data Lockdown sends anywhere is crash reports via Firebase Crashlytics (tied only to a random installation ID, with no name, scan results or app lists) and, if you turn on Network Monitor, DNS lookups forwarded to Cloudflare's 1.1.1.1 resolver. No analytics, no ads. Full details in our Privacy Policy.
The Network Monitor uses a VPN that runs on your Android device to inspect DNS queries, the requests your phone makes to look up website addresses. Those lookups are then forwarded to Cloudflare's 1.1.1.1 resolver to get real answers. Only DNS lookups are inspected, the rest of your traffic isn't touched, and nothing passes through our servers.
No. Lockdown never accesses your mic or camera. Sensor Watch listens for Android's own signals that the camera or microphone has switched on, so it doesn't need either permission. You can check this in Android Settings → Apps → Lockdown → Permissions.
Lockdown requires Android 8.0 (Oreo) or newer, and supports 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 camera and mic alerts (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.
