About this app

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.

Ratings and reviews

I purchased the military version of the app for a previous phone. When I went to re-install on a new phone, it required I purchase the product. I wrote customer service and explained the issue, and was granted a refund...that I never received. Now, I'm getting the run around. Beware! Eventually, you will upgrade your phone and find yourself feeling scammed out of your hard earned money.

It appears to clean files, caches, free space, or what items you select. It gives detailed reports. It appears to work well. The free version prompted me that I could only wipe a set amount of data per day. Though it doesn't restrict the amounts of free space you can wipe. That was a surprise. I wish it had an ability to examine some of the wiped areas for reassurance that it's doing the job. But with that, the app seems to work well. Thank you for the app iShredder!! I read some of the other reviews: The app freezes up? Sometimes the percentage completed stays at zero and elapsed timer is working. Chill! It will finish and give you a report! The photos you deleted only to find the photos still present? Those digger apps will find thumbnails in various clipboards and image caches. The error is likely your oversight. Look at the file size. Do some research!!

This works well, but there are more negatives than positives. I love 25 different ways to shred your files! Unfortunately only 5 are free, the rest u have to pay. Oftentimes u don't know which is which until u click on it and it tells u "upgrade required" to use that feature. Always choose FILE EXPLORER to pick files to shred, then go to INTERNAL STORAGE or SD CARD, then PICTURES (or whatever), & pick the ones starting w/ "trashed" in the name. Those are your deleted files. Too complicated!
