SecureFileShredder

SecureFileShredder lets you choose files with Android’s document picker and remove them using a best-effort 3-pass overwrite + delete process.

Writable files are processed in sequence. Read-only or unsupported files are skipped and included in the results.

This app does not promise forensic-grade erasure. On flash storage, cloud providers, and virtual document systems, physical wiping may not be possible.
