Disclaimer: All Files Access Permission

Device Health & Junk Cleaner requires the MANAGE_EXTERNAL_STORAGE permission to enable its core storage cleaning functionality.

This access is used to scan and remove:

Residual files left after app uninstallation

Obsolete APK files stored in various directories

Hidden and non-media junk files

System-generated clutter across device storage

Some of these files are located in areas that are not accessible through Android’s standard storage APIs, such as MediaStore or the Storage Access Framework. Therefore, broad storage access is required to ensure complete and effective cleanup.

The app may analyze file types, including media files (such as photos and videos), only for storage management purposes (e.g., identifying large or duplicate files). All processing is performed locally on the device.

We do not collect, store, or share any personal or sensitive user data.

Users remain in control:

All deletions require user confirmation

Permission can be revoked anytime via device settings

Without this permission, some cleaning features may not function fully.
