A Decade of Trust: 5 Million+ Users and 300,000+ TB Securely Wiped

You Own your Data.
Make Sure It Stays Only With You.

Shreddit executes deep, military-grade file shredding algorithms across internal memory and external partitions—wiping gallery caches, SD cards, and free space securely so that no one can ever recover your photos, messages, and files.

Designed for Absolute Data Destruction

Explore why Shreddit is the leading sanitization tool for personal and enterprise Android devices.

Multi-Pass Sanitization

Select from 9 specialized algorithms including German VSITR (7 Passes) and Russian GOST P50739 (2 Passes) to overwrite residual data beyond recovery.

Internal & External Wipe

Purge unallocated free space and confidential files across internal phone memory, external micro-SD cards, and connected OTG drives.

App Lock & No Ads

Keep your sanitization utility secure with PIN passcode protection, gallery thumbnail purging, and an ad-free interface in Shreddit Pro.

Complete Algorithm Roster

Supported Sanitization Standards & Algorithms

Shreddit includes 9 industry-standard sanitization methods developed through decades of data security research.

German VSITR
7 Passes

Runs three alternating overwrite cycles using patterns of ones (1s) and zeros (0s), followed by a final confirmation pass with a fixed character.

Russian GOST P50739
2 Passes

Executes a swift two-stage erasure cycle: the first pass writes continuous binary zeros (0s), followed by a second pass writing random bits.

British HMG IS5
3 Passes

Writes continuous binary ones (1s), followed by continuous binary zeros (0s), and completes with a final pass of random bit values.

US DoD 5220.22-M
3 Passes

Overwrites blocks with zeros (0s), then ones (1s), followed by pseudo-random binary sequences, verifying each write cycle.

Bruce Schneier
7 Passes

Pass 1 writes binary zeros, Pass 2 writes binary ones, followed by 5 subsequent passes writing distinct cryptographically random values.

NIST SP 800-88 Rev 1
2 Passes

The modern data security standard recommended by NIST specifically for sanitizing mobile flash storage and SSD media.

Custom Filler Modes (Advanced & R&D Testers)

For developer diagnostics and forensic testing, Shreddit allows custom pass fills:

• Random Filler: Writes pseudo-random binary variables.
• Zero Filler: Writes continuous hex bytes representing 0x00.
• One Filler: Writes continuous hex bytes representing 0xFF.

Why Standard Deletion Fails

When you delete a file on standard Android file systems, the system merely removes the pointer entry. The raw binary structures sit intact on your physical flash blocks until overwritten.

Furthermore, the stock Android gallery leaves high-resolution thumbnail previews cached in system directories. Shreddit targets raw block addresses, overwrites sectors, and purges hidden gallery caches completely.

Power Optimization Best Practices

High-pass file overwriting requires significant CPU cycles and flash write activity. Manage your battery safely:

  • Plug In to AC Power: Always connect your charger before running multi-pass algorithms or wiping large storage volumes (64 GB–512 GB+).
  • Maintain Minimum Battery: Do not start a deep wipe if battery level is below 30% without an active power source. A forced shutdown mid-pass can cause filesystem instability.
  • Remove Protective Cases: Heavy continuous write operations cause thermal build-up. Removing thick cases improves heat dissipation and prevents thermal throttling.
  • Pause Resource-Heavy Apps: Close gaming, video rendering, or camera recording apps to dedicate full disk I/O throughput to Shreddit.
SD Card, OTG Drives & Rooted Devices
Android 6.0+ Unrooted Method
  1. Go to Android Settings > Storage > Portable Storage and select your SD card.
  2. Format the card to clear index headers (standard format).
  3. Open Shreddit and run Wipe Empty Space on the formatted SD card to securely sanitize all blocks.
Rooted Devices (Android 4.4 & 5.0+)
  • Android 4.4 KitKat: Use SDFix: KitKat Writable MicroSD to fix write permissions, then restart.
  • Android 5.0+ Lollipop: Move Shreddit to system app directory via /System/App Mover.
Temporary Storage System Notice During a Wipe Empty Space task on internal storage, Android may show a "Storage space running out" notification. This is temporary while Shreddit allocates unallocated blocks. It clears automatically upon job completion.

Frequently Asked Questions

Answers to common queries about Shreddit operational safety, pricing, and system behaviors.

Shreddit is fully functional freeware for primary file shredding, algorithm selection, and internal storage wiping. Upgrading to Shreddit Pro provides an ad-free environment, external storage access, and simultaneous background jobs.

Shreddit does not collect, track, or share any of your personal files or local activity. The Free edition contains standard AdMob ads, while Shreddit Pro removes all ads entirely.

Shreddit stabilizes your device on reboot and automatically releases any temporarily acquired empty space blocks.

Yes, in Shreddit Pro, you can run multiple shredding tasks simultaneously across separate storage mounts by moving active tasks to the background.

The app displays a color-coded battery status indicator. We advise connecting your phone to an external charger if your battery level is below 30% before starting multi-pass passes.
