About this app

SecureFileShredder gives you a deliberate way to dispose of a file rather than simply moving it to the trash. Choose one or more files with the system document picker, and the app overwrites each writable file in three passes before deleting it.

Batch work is built in. Select several files at once and review a per-file result list when the run finishes. Items that are read-only, or served by a provider that does not allow writing, are skipped safely and reported in the results, so you always know what actually happened to each file instead of being told everything succeeded.

About the limits, stated plainly
On modern UFS and eMMC flash storage, in cloud-synced folders, and through some manufacturer file managers and virtual document providers, repeated overwriting cannot guarantee forensic-grade erasure. Wear levelling and copy-on-write mean the storage layer may keep the original blocks out of reach of any app. This tool performs a best-effort overwrite and delete, and only where the provider grants read and write access. It does not claim to defeat laboratory recovery.

Everything runs locally through the Storage Access Framework. The app requests no broad storage permission, needs no account, and no file ever leaves your device.
