Kura is a lightweight, privacy-focused security layer for Android, designed to protect your apps with biometric and device-level authentication without the corporate bloat.
Important
Kura intentionally does NOT support Android 16 (API 36) or later. We refuse to comply with Google's mandatory "Verified Developer" registries and their systematic destruction of independent sideloading. This app is built for users who own their devices, not for corporations that want to rent them back to you. We stand for a truly open Android.
- Android Studio (Ladybug or newer)
- JDK 17 (Required for latest Gradle/Compose)
- Android SDK (API 24 to 35)
