Shredder

Shredder is a high-security Android application designed to permanently and irrecoverably delete files and directories. It implements industry-standard multi-pass shredding algorithms to thwart data recovery even from specialized hardware forensic tools.

🚀 Key Features Multi-Pass Shredding: Implements a robust 3-pass overwrite algorithm. Metadata Wiping: Renames files to random strings and truncates them before final deletion to hide original file identities. Free Space Wiper: Securely wipes available free space on the device storage to prevent recovery of previously deleted files. Nuclear Option: Integrated device administrator capability to trigger a secure factory reset (wiping all data). Foreground Execution: Uses Android Foreground Services to ensure long-running shredding tasks complete successfully even if the app is in the background. Biometric Security: Protects the entire application and high-risk operations (like the Nuclear Option) with Biometric/PIN authentication. Notification Support: Fully compatible with Android 13+ notification permissions for reliable foreground execution. Modern UI: Built entirely with Jetpack Compose for a responsive, fluid user experience, featuring a collapsible real-time console.
