  1. Open Google Play from the Apps screen of your device and search for Avast Cleanup.
  2. Tap Avast Cleanup & Boost to open the app information page.
  3. Tap Uninstall, then tap OK to confirm the uninstallation.

Cleanup is no longer installed on your device.

Can I double check items that I add to the trash before deleting them?

Yes. To check the items that you select for deletion before permanently removing them from your your device, ensure that the Trash review option is turned on in your Cleanup settings. Tap (or swipe to) the Tools tab, tap Settings, then turn on the Trash review option. Files, media, apps, and app data that you delete are added to the Trash. From there, you can remove items if you change your mind, or permanently delete them if you're certain.

Why do I need to grant the Usage Access permission to Cleanup?

On the Apps tab, Cleanup provides an overview of the apps that you have installed on your device and their downloaded data. Without the Usage Access permission, Cleanup can provide only limited information about your apps. For example, instead of being able to show you the number of large and unused apps, Cleanup displays only the number of apps installed on your device. Further, Cleanup can only sort your apps and app data by size, and not also by name or usage.

You can grant the permission in the Apps with usage access section of your device settings. Tap the question mark on the Unused Apps box then tap Yes to open your device settings.

What types of files are processed during a Safe clean and can I customize them?

When you tap the Safe clean button on the Cleaning tab, the app scans for the following items and caches which are unnecessary for the performance of your device:

  • Thumbnails
  • Hidden Cache
  • Visible Cache
  • APKs
  • Residual files
  • Shared Cache

You can configure Safe clean to ignore any item type that you do not want to be deleted. Tap (or swipe to) the Tools tab, tap Settings, then tap Safe cleaning. On the next screen, tick or untick the file types according to your preferences. By default, all types are ticked except for Thumbnails.

Why is the Safe clean scan running slowly or paused mid-progress?

During a scan, Cleanup probes several folder-levels deep to identify all dispensable data on your device. Depending on the number of items Cleanup needs to scan and the computing power of your device, a scan may take several seconds to a number of minutes. If the scanner encounters a particularly complex folder, a notification is displayed in the scanner progress bar. To provide feedback about unusually long scan processing times, please use the in-app Feedback form.

Can I exclude apps from Memory Boost?

Yes. The first time you use the Memory Boost feature, you are prompted to use the Memory Boost check which enables you to deselect any apps that you do not want to be affected by a Memory Boost. By default, all non-system apps are selected. You can also turn the Memory Boost check option on in Settings (located under the Tools tab) so that each time you tap the Memory Boost button, you can review the exact apps that will be affected and deselect any that you do not want to be stopped on that occasion.

Can I keep copies of the media and files I transfer to cloud storage on my device?

Yes. Simply turn off the option to Delete files after transfer in the Cloud services section of your Cleanup Settings which you can open from the Tools tab. This setting affects all connected cloud services.

Where can I find items after they are transferred to cloud storage?

To locate an item that you transferred to cloud storage, sign into your cloud storage service and access the relevant folder:

  • In Dropbox: Avast Cleanup in the Apps folder
  • In OneDrive or Google Drive: AvastCleanup folder

Your transferred items are organized in the same way that they were organized on your device.

What is the Cleaning tab for?

The Cleaning tab indicates the percentage of used storage space on your device, or the amount of available storage space if you tap the percentage shown. In addition, you can quickly and safely remove space-wasting data by tapping the Safe clean button, or release memory space by stopping all running apps (excluding system apps) using the Memory Boost feature.

What is a Safe clean?

Safe clean is an automated action that removes dispensable files from your device to free your storage space. You can define the exact types of items that are cleaned in your Cleanup settings.

How can I be sure that important items are not deleted during a Safe clean?

The Safe clean function was carefully designed to only remove data that is truly dispensable such as system caches that can be easily replaced, or already installed APK files. If you're concerned, you can define the exact types of items that are cleaned in your Cleanup Settings, and also turn the Safe clean check option on to check items before they are deleted.

Can I check files before they are deleted by Safe clean?

Yes. To review items that are identified for deletion by Safe clean, turn the Safe clean check option on. Tap (or swipe to) the Tools tab, tap Settings, then tap Safe cleaning, and turn the Safe clean check option on. Each time that you run a Safe clean, an overview of all items is displayed before you perform the deletion. You can untick items that you do not want to delete before completing the clean in all categories except for Hidden Cache, which can be cleaned all at once or not at all.

Can I restore files that were deleted during a Safe clean?

No. You can't restore the files that are deleted during a Safe clean. This function was designed to only remove dispensable data such as system caches and already installed APK files. If you're concerned, however, we recommend that you turn the Safe clean check option on in your Cleanup Settings to review items before proceeding with any deletions.

Why does the Safe clean button show such a low amount of removable space?

If you have recently run a Safe clean, the amount of removable space may be low because your apps have not created more dispensable data yet. Another reason may be that some of your Safe clean categories are unchecked and therefore ignored when the clean is run. Check the categories in your Safe cleaning settings, if you are concerned.

Why is the Thumbnails category turned off by default?

Thumbnails are the small versions of pictures used for previews. Deleting thumbnails can release significant amounts of data on some devices, while on others the effect is very limited. For this reason, this category is unchecked by default. You can test the effectiveness of this option on your device and decide whether to check it or not.

What is the Memory Boost feature?

When you tap the Memory Boost button on the Cleaning tab, Cleanup stops all non-system apps from running in the background. This action makes the memory space that was occupied by this background activity available for other purposes.

How long do the effects of a Memory Boost last?

The amount of memory a Memory Boost frees on your device and how long it lasts depends on how active your apps are, and whether they automatically restart or require a manual restart. Some apps instantly reload and continue to occupy memory space, others reload but consume less memory than before the Memory Boost, and some do not affect your memory again until you actively reopen them.

Can stopping apps with Memory Boost be harmful to an app?

Mobile apps are designed to cope with sudden closures, which means that typically the action of stopping apps via the Memory Boost feature should not have a detrimental impact on your apps.

What is the Apps tab for?

The Apps tab provides a summary of the apps that you installed on your device and their downloaded data. Pre-installed device applications are not included. From this tab, you can also remove any apps or app data that you do not need.

How can I delete unwanted Apps from my device?

On the Apps tab, tap the Applications button at the bottom of the screen to open a display of your installed apps and the amount of data they are consuming. Select one or more apps and tap the Delete icon which appears at the bottom of the screen.

What is App Data and what are the consequences of deleting it from my device?

App Data is the data that is accumulated and stored (often unnecessarily) on your device when you use certain apps. Cleanup identifies App Data that you can safely remove from your device, however, we recommend that you delete such data with caution. Always consider the impact of its removal on the functionality of the source app. For example, each time you open Google Maps, the app re-downloads any offline maps that were removed by Cleanup. Similarly, Spotify re-downloads offline tracks when needed. Conversely, deleting OBB type App Data, which is often associated with large games, may release a lot of space on your device while allowing you to keep the game, but, you may need to re-install or re-download the OBB file if you decide to continue the game.

How can I delete App Data from my device?

On the Tools tab, tap App Data to open a display of the App Data that you can clean from your device. If you delete an App Data file, all data related to the selected application, including the custom settings or OBB files related to the additional features bought on Google Play, are deleted. After you delete these files, the application runs in default configuration with no additional features.

You can also add individual App Data items to Safe Clean. To do so, tap the three-dot menu icon in the top-right corner of the item that you want to add to Safe clean, then tap Add to Safe clean.

How can I organize Apps and App Data in Cleanup?

On the Applications or App Data pages of Cleanup (which you can open from the Apps tab), your apps or app data are, by default, displayed according to Size. However, you can also display apps or app data by Name, and apps by Usage. Tap the Statistics icon at the top-right to change the setting.

Why don't certain app caches appear in the App Data section?

The items included in this section are limited to data from some of the most commonly used apps. These apps have been carefully analyzed and selected to be included, as deleting them is unlikely to cause issues with your device. Regardless, we recommend that you always use caution when deleting App Data.

What is the Media & Files tab for?

The Media & Files tab enables you to manage the media and files content on your device by deleting or transferring such items directly to a Dropbox, Google Drive, or OneDrive cloud storage service. The media on your device refers to all images, videos, and audio files that are created on your device, downloaded from the internet or maintained by a common application, and files may include various types of documents such as PDFs, spreadsheets, and presentations, as well as archives (for example, ZIP files), HTML files, and residual APK files.

You can also see exactly how much space each of your media and files items is consuming, and remove or transfer them one-by-one or as a group.

How can I organize Media and Files in Cleanup?

By default, media and files are displayed according to Size on the Media or Files pages (which you can open from the Media & Files tab). However, you can reorganize media and files in the following ways:

  • Type
  • Size
  • Name
  • Data
  • Folder
  • Upload status

To change this setting, tap the Statistics icon at the top-right and select your preferred option.

What is 'the cloud' and which cloud storage services does Cleanup support?

'The cloud' refers to virtual storage space where you can keep media and files such as photos, videos, and documents. Several cloud storage providers exist. With the Cleanup app, you can connect to and transfer files and media from your device directly to Dropbox, Google Drive, and OneDrive.

At one time, you can connect to multiple Google Drive accounts, one Dropbox account, and one OneDrive account.

How do I add an item to a cloud transfer queue?

In the Media or Files sections (which you can open from the Media & Files tab), select any items that you want to transfer and tap the cloud icon that appears. Select the connected cloud service that you want to transfer the items to. If your device is connected to the internet (or Wi-Fi if you turned on Upload files only on Wi-Fi), the transfer starts immediately.

How can I disconnect a cloud storage account from Cleanup?

In the Cloud services section of Settings (which you can open from the Tools tab), tap the menu icon beside the account that you want to disconnect and tap Sign out.

Why does a file upload restart from the beginning after a transfer queue is paused?

Because incomplete file transfers are automatically deleted by cloud services when a transfer is paused, you can only pause and resume an entire queue.

Why did Cleanup fail to transfer an item to my cloud storage account?

The main reasons a file may not be transferred are:

  • Poor quality or unavailability of an internet connection.
  • Unavailability of the cloud storage service.
  • Insufficient space availability in your cloud storage account.

If you encounter a transfer fail, retry the transfer at a later time or with a different service.

What is Cleanup?

Cleanup is a free application which helps to improve the performance of your device and preserve your storage space by identifying and enabling you to remove unnecessary media, files, apps, and app data that may slow your device down.

How can I customize or disable the notifications I receive from Cleanup?

Cleanup provides the following types of notifications to remind you when your mobile device may need cleaning:

  • Unused app(s) reminders: tells you if you haven't used an app for a selected amount of time.
  • Storage space warning: tells you if you reach a selected amount of remaining storage space.
  • Dispensable data reminder: tells you if you have a selected amount of data that can be safely removed.
  • Media transfer reminder: tells you if you have a selected amount of media that you may want to transfer to the cloud.

If you do not want to see these warnings (or you want to customize them), open Settings from the Tools tab, tap Notifications, then tap a notification type and disable it or change the conditions for receiving it.

What does 'Scanner updated' relate to in the About application section of Settings?

The Cleanup scanner is regularly updated to ensure that the app is as effective as possible. When improvements are made, the scanner configuration is automatically updated on your device (with a super-tiny download), and the date is reflected in the Scanner updated section of the About application screen. To see this section, tap (or swipe to) the Tools tab, tap Settings, then tap the three-dot menu icon, and tap About application.

How can I give feedback about the app?

There are many ways that you can provide your feedback, or show your appreciation and support of Avast mobile products. For example:

  • Write a positive review on Google Play.
  • Tell your friends about our software via Facebook or Twitter.
  • Post reviews in Android related forums.

Why does Avast show advertisements in mobile apps?

Avast is pleased to offer the Cleanup app to customers for free, and are confident that you will find the app to be highly advantageous to the performance of your device. To support the ongoing development of the app, we allow ads only at the end of each cleaning process which we believe to be unobtrusive, and that do not interfere with app usage.
