iShredder™ – secure data eraser & file shredder for Android
iShredder helps you securely erase photos, files and empty space so deleted data becomes extremely difficult to recover – even with recovery apps or forensic tools. Run a wipe before you sell, trade in, recycle, repair or hand over your device and keep your private information private.

WHY A SIMPLE DELETE OR FACTORY RESET ISN’T ENOUGH
On Android, “delete” often removes only directory entries. The underlying data blocks can remain on storage and may be found later by recovery software. iShredder uses certified secure deletion algorithms to overwrite empty space and selected storage areas multiple times, helping remove traces of previously stored data so your content is not just hidden.

MILITARY‑GRADE, CERTIFIED ERASURE METHODS
iShredder supports proven wiping methods based on internationally recognized standards such as DoD 5220.22‑M, NIST SP 800‑88, BSI TL‑03423 and more. These algorithms overwrite data with carefully chosen patterns to make recovery extremely difficult.

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

PRIVACY & SECURITY BY DESIGN
iShredder is built with security in mind. During the DEKRA MASA L1 assessment, independent experts confirmed the app 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 your data with third parties.
