Free. No account. No ads. 100% offline. Just download the APK, install it, and your vault is ready in under a minute.
Tap "Download APK" above. Your browser will download app-debug.apk to your Downloads folder. The file is approximately 8 MB.
Go to Settings → Security → Install Unknown Apps. Select your file manager or browser and enable "Allow from this source". This only needs to be done once.
Open your Downloads folder, tap app-debug.apk, and tap Install. Launch the app — it opens as a calculator. Set your secret PIN in the settings, then use it to unlock the vault.
Your vault is active. Import photos, videos, or documents. Lock apps. Set your decoy PIN. Enable the intruder selfie. You're fully protected.
Prefer to compile the APK yourself? Clone the repo and build with Gradle. Requires Android Studio Jellyfish+ and JDK 17.
