What to includeWhat to include in a bug report
Nimbus Cleaner behaves differently across Android versions and manufacturer skins, so the same tool can work on one phone and fail on another. These details narrow it down quickly:
- Your device manufacturer and model
- Your Android version
- The Nimbus Cleaner version, from the app's settings screen
- Which tool you were using — Junk Cleaner, Similar Photos, and so on
- What you expected to happen, and what happened instead
- A screenshot, if the problem is visible on screen

Why each permission is requested
A cleaner app cannot review files it is not allowed to see. Every permission below maps to a specific feature, and each one is optional — the app simply loses the feature that depends on it.
| Permission | What it is used for |
|---|---|
| Storage and media | Scanning and displaying files, photos, videos, audio and junk items. |
| All files access | Where your Android version and the feature require it: reviewing and managing files across shared storage for the cleaner tools. |
| Notifications | Showing reminder and foreground notifications. |
| Notification listener access | Reviewing and clearing notifications when the notification cleaner is enabled. Optional — the rest of the app works without it. |
| Query installed packages | Displaying installed apps for software management and app review. |
| Request delete packages | Helping uninstall apps through the standard Android system flow. |
| Network permissions | Checking connectivity and supporting app operation. |
| Foreground service | Keeping reminder or resident notification features available when they are enabled. |
You stay in control. Any permission can be denied or revoked in Android system settings at any time. Features that depend on a revoked permission stop working; nothing else in the app is affected. The full list is in section 5 of the Privacy Policy.
Common problems
A tool finds nothing, or the list is empty
This is almost always a permission that was not granted, or was revoked later. Open Android Settings, find Nimbus Cleaner under Apps, and check the storage and media permissions. On newer Android versions, the cleaner tools may also need all-files access.
The notification cleaner shows nothing
Clearing notifications needs Android's notification listener access, which is granted in system settings rather than in a normal permission prompt. Until it is enabled, the notification cleaner has nothing to read.
An app would not uninstall
Nimbus Cleaner starts the uninstall, but Android itself finishes it. The system dialog has to be confirmed, and some system or manufacturer apps cannot be removed at all.
I deleted something I needed
Deletions may be permanent, depending on Android's behaviour and your device's storage state — Nimbus Cleaner has no recycle bin. Review the selection before confirming a cleanup, and keep a backup of anything important. This is covered in section 4 of the Terms of Service.
Results differ from another cleaner app
Cleaner apps count different things as junk, and Android reports storage sizes differently across versions and manufacturers. Nimbus Cleaner reports what it found under the permissions it was given.
Privacy and terms
The Privacy Policy covers what the app accesses on your device and what it does not do with that information. The Terms of Service cover use of the app, responsibility for cleanup actions, and the disclaimers that apply.
