iShredder™ is a leading secure data eraser app and file shredder for Android.
It permanently wipes photos, files and free space so deleted data is designed to be unrecoverable – even with professional recovery tools. Use it before you sell, recycle or hand over your device and make sure your private data really stays private.

WHY NORMAL DELETION ISN'T ENOUGH
Deleting a file or running a basic factory reset usually only removes directory entries. The data itself often remains on the storage and can be recovered later with simple recovery apps or forensic software. iShredder overwrites this free space with certified secure deletion algorithms so your data is gone for good, not just hidden.

MILITARY‑GRADE, CERTIFIED ERASURE
iShredder uses certified erasure methods such as DoD 5220.22‑M, NIST SP 800‑88, BSI TL‑03423 and other international standards that are trusted by military and government organizations. These algorithms overwrite data multiple times with carefully chosen patterns to make recovery extremely difficult.

The Android app has been independently audited and awarded DEKRA MASA L1 security certification, confirming compliance with OWASP MASVS Level 1 guidelines. iShredder has also received the Fortress Cybersecurity Award 2025, underlining its focus on both robust erasure methods and strong app security.

PRIVACY & SECURITY BY DESIGN
iShredder not only erases data securely – the app itself is built with security in mind. As part of the DEKRA MASA L1 assessment, independent experts confirmed that iShredder follows OWASP best practices and contains no common vulnerabilities. All connections from the app to Protectstar services use modern TLS encryption. The app avoids unnecessary data collection and, as declared in the Google Play data safety section, does not share data with third parties.
