This release introduces critical stability enhancements, a more protective user experience, and a hardened architecture to ensure reliable data sanitization under all conditions.
🛡️ Core Security & Reliability Hardening
- Operational Keep-Awake Hardening: Added in-app
FLAG_KEEP_SCREEN_ONduring active destructive operations alongside a service-levelPARTIAL_WAKE_LOCKlifecycle. This drastically reduces the risk of the OS pausing or throttling long-running shredding tasks when the device goes idle. - Secure Temp Wipe Cleanup: Free-space wipes and legacy free-space teardowns now securely clean temporary wipe artifacts using a strict, metadata-minimizing deletion flow (rename ➡️ truncate to 0 ➡️
fd.sync()➡️ delete). - Recursive Symlink Guards: Enhanced canonical path tracking to prevent infinite loops from circular symlinks during recursive folder shredding.
🎨 UX & Interface Improvements
- Hardened Danger Zone in Settings: Removed the highly destructive "Nuclear Option" (Full Factory Reset) and "Device Admin" buttons from the main screen's top app bar to prevent accidental triggers. They are now safely isolated within a dedicated, red-bordered "Danger Zone" card at the bottom of the Settings screen.
- Improved Free Space Wipe Telemetry: Integrated dedicated status and progress messaging tracking for writing, cleanup, completion, cancellation, and failure states.
- State-Preserving Navigation: Replaced inline screen-switching logic with a unified, type-safe
AppScreenenum-driven state. Your current directory level, file selections, and search/sort queries will now fully survive transitions to Settings or About screens and back. - Contextual Back-Button Interception: Registered a Compose
BackHandlerthat smartly intercepts the system back button—navigating up parent directories or returning from secondary screens—without abruptly exiting the app unless you are at the storage root. - Accessible About Screen Links: Wrapped both labels and URLs in unified clickable rows featuring underlined styling and primary color highlights for better target accessibility.
⚙️ Under the Hood
- Target SDK Update: Upgraded project configurations to target Android SDK 36 (Minimum SDK remains 24).
- Dead Code Cleanup: Eliminated the unused legacy
Shredder.ktfile to improve project maintainability and codebase cleanliness. - Language & Tooling: Powered by Kotlin 2.2.10 and built entirely on Jetpack Compose.
⚠️ Disclaimer: Data deleted with Shredder is permanently IRREVERSIBLE. Please double-check your file selections before confirming destruction.
