Direct download signed with Guardyn’s official developer release key. Independent of Google Play Store with autonomous in-app updates.
Your Pro status transfers seamlessly! Guardyn authenticates entitlements via our secure server linked to your Google Account. When you install the Direct APK and sign in with Google, your Pro features activate automatically. Your recurring renewal remains managed at Play Subscriptions.
Guardyn Standalone features a built-in autonomous update engine. You do not need to download future APKs manually. When a new version is released, the app cryptographically verifies the SHA-256 hash and developer certificate, then provides a 1-tap in-place update dialog right inside the app.
* Note: Google Sign-In and background remote-control features require a compatible Google service environment. FCM-based remote commands require Google Play services. Pure de-Googled AOSP without microG or equivalent compatibility is not supported.
