Junk Cleaner: Storage Cleanup

Trung-Hieu Tran

About this app

Running out of space? Junk Cleaner shows you exactly what is taking it, and lets you decide what goes.

Nothing is deleted behind your back. Every tool lists the files first, nothing is ticked by default, and anything you remove goes to a Trash you can restore from.

CLEAN UP
• Junk & cache – leftover temporary files, logs, thumbnail caches and half-finished downloads in folders you choose.
• Duplicate files – exact copies found by content, not by name.
• Similar photos – burst shots and near-identical pictures, ranked by sharpness so the best one stays.
• Large files – the biggest media on your phone, biggest first.
• APK files – old installers you no longer need.
• Downloads – everything in your Download folders, biggest first; documents are marked so you do not remove them by accident.
• Short video & audio – tiny clips and stray recordings you probably never meant to keep.
• Empty folders – tidy up what is left behind.

YOUR DEVICE
• Speed test – download, upload, ping and jitter in about 20 seconds.
• Storage & RAM – real readings straight from Android, with a plain explanation of what they mean.
• Apps – sizes, last used, uninstall.
• Storage map – see what is taking the space, drawn to scale.

FILES
• Browse, copy, move, rename and delete in the folders you grant.
• Just arrived – files added in the last 7 days.
• Trash – restore anything this app removed.
• Encrypted vault – lock private files behind your password.

HONEST BY DESIGN
• No "boost RAM" or "kill apps" buttons. Android manages memory itself, and those buttons only show a number that drops back in seconds.
• No scary red warnings and no fake "your phone is slow" alerts.
• Free, with no ads and nothing to buy.
• Works offline. The only feature that uses the internet is the speed test, and it only exchanges random test data with Cloudflare's public speed server. No file names or personal data leave your phone.
• Usage statistics and crash reports are off until you turn them on in Settings.

PERMISSIONS
The app asks for access to your files so it can scan for junk, duplicates and large files, and to see which apps are installed so it can list their sizes. It uses this only on your phone, only when you open a tool.
