Data Eraser - iShredder

iShredder™ – military‑grade data eraser & file shredder for Android

Securely erase and permanently delete 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. Create erasure reports for your records and reduce privacy risks when a device changes hands.

WHY NORMAL DELETION 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. Even a basic factory reset may not remove every trace of previously stored content. iShredder overwrites empty space and selected areas multiple times using certified methods, helping remove traces of old data (not just “hidden”). This is especially useful after you’ve deleted many files or uninstalled apps.

CERTIFIED, MILITARY‑GRADE ERASURE

Choose wiping algorithms based on trusted standards such as DoD 5220.22‑M, NIST SP 800‑88, BSI TL‑03423 and more. Multi‑pass overwriting with carefully chosen patterns makes recovery extremely difficult and is commonly used for high‑sensitivity data.

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

KEY FEATURES

• Securely erase sensitive data — wipe photos, videos, documents, downloads and folders

• Wipe empty space — overwrite remnants of previously deleted data (internal storage & supported SD cards)

• Clean caches & junk securely — remove hidden caches, logs, temporary files and thumbnails

• Built‑in file explorer — select exactly what to shred: files, folders or storage areas

• Multiple certified deletion algorithms — from fast one‑pass wipes to strict multi‑pass methods

• Detailed erasure reports — generate a report after each wipe (date/time, method, result) for audits and privacy policies

• BYOD & shared device wipe — remove work data before return, reassignment or handover

TYPICAL USE CASES

• Wipe your phone before selling or trading it in (resale marketplaces, buy‑back programs).

• Prepare a device for repair: remove private photos, documents and app traces first.

• Remove sensitive files (IDs, contracts, client data) that must not be recovered.

• Clean corporate phones/tablets and BYOD devices used for work data.

• Reduce leftover traces after uninstalling apps by wiping empty space.

• Securely hand over a shared device to the next user with an erasure report.

EASY 3‑STEP WIPE

1) Select what you want to erase: files, folders, app data, empty space or storage areas.

2) Choose a certified deletion algorithm that matches your security needs.

3) Start the wipe — iShredder overwrites the data and generates an erasure report for your records.

FOR BUSINESS, IT & PUBLIC SECTOR

iShredder can support internal secure‑disposal workflows by producing erasure reports and enabling repeatable wipe processes across devices. It is useful for device rotation, onboarding/offboarding and documented data wipe procedures (including GDPR‑aligned policies when combined with your organization’s compliance process).

PRIVACY & SECURITY BY DESIGN

All connections to Protectstar services use modern TLS encryption. The app avoids unnecessary data collection and, as declared in Google Play’s Data Safety section, does not share your data with third parties.

Note: Availability of features can vary by device, Android version and iShredder edition.

Take control of your privacy and make sure “deleted” really means deleted — with iShredder for Android.
