About this app

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.

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!
