About this app

Welcome to QuixiCloud Sync — Your Digital Life, Synchronized.

QuixiCloud Sync is the official native companion app for QuixiCloud Storage. We’ve moved beyond manual file hosting to bring you a true "set-it-and-forget-it" automated backup engine. Protect your photos, videos, and professional documents in real-time with zero-knowledge, end-to-end encryption.

⚠️ IMPORTANT REQUIREMENT: This native background sync app is a Premium Feature. It requires an active QuixiCloud Yearly Plan. Free tier users must upgrade to generate the required WebDAV App Passwords to connect the app.

Why Choose QuixiCloud Sync?
Stop worrying about losing your phone or manually dragging files into web browsers. QuixiCloud Sync runs quietly in the background, ensuring your memories and critical data are safely secured in your personal cloud vault the moment they are created.

CORE FEATURES

Intelligent Auto-Backup
• Real-Time Protection: Back up your camera roll, downloads, or any custom folder automatically.
• Smart Delay Engine: Taking a burst of photos? The app waits before syncing, giving you time to delete bad shots before they consume your cloud storage.
• Delta-Sync Technology: We only upload what changes, saving your mobile data and battery life.

Zero-Knowledge Privacy
• End-to-End Encrypted: Your files are encrypted locally on your Android device before they ever reach our high-performance M-S3 infrastructure. We cannot see, scan, or sell your data.
• Local-Only Indexing: The directory of your files stays exclusively on your phone.
• Hardware-Level Security: Your WebDAV app passwords are locked within the Android Keystore (AES-256).

Device-Isolated Vaults
Have multiple phones on one account? QuixiCloud automatically creates separate, isolated Vaults for each device (e.g., your Pixel and your Samsung won't mix files). Keep your data perfectly organized and conflict-free.

Safe "Free Up Space" Management
Running out of local phone storage? Our intelligent cleaner strictly verifies that a file has been successfully uploaded—and checks its exact MD5 hash for bit-perfect accuracy—before it ever offers to delete the original from your phone. You will never lose a memory to a failed sync.

Battery & Data Optimized
Built using Android’s native WorkManager, QuixiCloud Sync respects your device. You can set rules to sync only on Wi-Fi or only when your phone is Charging, ensuring your daily battery life remains untouched.

HOW TO LOG IN (Premium Users Only):
* Log into the QuixiCloud Web Dashboard on your browser.
* Navigate to the Connect & Mount tab on the left menu.
* Create a new App Password (Annotation) for your Android device.
* Enter your registered email and the newly generated 26-character secure
password into the app.

Permissions Notice:
To provide seamless background protection, this app requires "All Files Access" to locate your media, and "Unrestricted Battery" access to prevent Android from killing your backup process while you sleep.
