Are my files sent to a server?

No. Every scan and cleanup in Sweepo runs 100% on your device. No file or photo is ever transmitted anywhere — there's no server and no cloud.

Can I recover deleted files?

Deleted files can't be recovered. That's why Sweepo never deletes anything automatically — it always shows you the list first, and only removes items you selected yourself. Please double-check before deleting.

Why does it need all-files access?

The permission is used only to scan your storage for junk, duplicates and large files, and to clean the items you select. Files it reads never leave your device and are never used for anything else.

Yes, it's free. It includes ads, but the app stays lightweight and every feature — junk, duplicate photos and large file cleanup — is free to use.

Why Is My Phone Storage Full? 5 Hidden Causes and Their Fixes

"I barely installed anything - why is my storage full?" Every Android user hits this question eventually. The culprits are usually invisible in daily use. This article covers the five most common storage thieves and how to deal with each one.

Cause 1: App cache grows silently

Social, video and shopping apps cache images and data on your device for faster loading. The catch: cache never shrinks on its own. After a few months, a single app can hold hundreds of megabytes or even gigabytes of cache. Since cache regenerates when needed, clearing it periodically is safe and effective.

Cause 2: Media saved by messaging apps

Messengers like WhatsApp often auto-save photos and videos from your chats. A few active group chats can pile up thousands of greeting images, memes and clips. Turn off auto-download in your messenger's settings, then clean out the media folders that have already accumulated.

Cause 3: Screenshots and burst photos

A screenshot is only 1-3MB, but hundreds of them add up to gigabytes. The same goes for near-identical photos from burst mode and retakes. Both are classic "needed it then, not now" files.

Cause 4: Forgotten files in Downloads

PDFs from the browser, videos watched once, and APK installers for apps you already installed tend to sit in the Downloads folder forever. Sort it by size every few months and clear the dead weight.

Cause 5: The mysterious 'Other' category

If the storage screen in Settings shows a large 'Other' slice, it's usually app leftovers: logs, temp files and empty folders. The system screen won't tell you what they are, which makes them hard to find without a cleanup tool.

Diagnose and clean in one place with Sweepo

You don't have to chase each cause by hand. Open Sweepo and it scans junk (cache, logs, temp files, APKs), duplicate files, similar photos, screenshots, and large or old files - sorted by category. You always review the list and pick what to delete yourself, and everything runs entirely on your device.
