3. Permissions We Request and How We Use Them
We may request certain device permissions to provide core features of the Application. These permissions are used only for the purposes described below. You can manage or revoke permissions at any time through your device settings, although some features may not function properly if a permission is denied.
(1) All Files Access Permission / Manage External Storage
On certain Android versions, the Application may request the "All files access" permission (also related to MANAGE_EXTERNAL_STORAGE) to provide file cleaning, file management, duplicate file detection, large file scanning, and storage optimization features.
With this permission, the Application may access:
- Files and folders stored on your device's internal storage or external storage
- File metadata such as file name, file type, file size, folder path, and creation/modification date
- Basic file content information necessary to identify duplicate, junk, obsolete, or large files
We use this permission solely to:
- Scan and analyze files stored on your device
- Identify duplicate files, junk files, cache files, residual files, large files, and other files that may be safely cleaned
- Allow you to manage, delete, or clean selected files
- Calculate storage space that can be freed
We do not upload your files or file contents to our servers. File scanning and cleaning are primarily performed locally on your device. If any file-related information is transmitted, it will be limited to aggregated, anonymized, or diagnostic data, such as scan results statistics, cleaning duration, storage space freed, and crash logs, and will not include your actual file contents.
You can revoke this permission at any time in your device settings. If you revoke it, file cleaning and file management features may be unavailable or limited.
(2) Read Installed App List Permission
The Application may request permission to read your installed application list (for example, QUERY_ALL_PACKAGES or equivalent Android permissions) to provide app management, app cleaning, app analysis, and related features.
With this permission, the Application may access:
- A list of applications installed on your device
- Basic app information such as app name, package name, version, installation time, update time, and app size
- Whether an app is a system app or a user-installed app
We use this permission solely to:
- Display installed apps within the Application
- Identify app caches, residual files, APK files, and other app-related junk files
- Help you manage, uninstall, or clean app-related data
- Provide app usage and storage analysis features
We do not use this permission to collect your personal messages, contacts, photos, or other content within your apps. Installed app list information is primarily processed locally on your device. If any related information is transmitted, it will be limited to aggregated, anonymized, or diagnostic data for analytics, crash reporting, and service improvement.
You can revoke this permission at any time in your device settings. If you revoke it, app management and app cleaning features may be unavailable or limited.
(3) PACKAGE_USAGE_STATS / Usage Access Permission
The Application may request "Usage Access" permission (PACKAGE_USAGE_STATS) for certain features. This permission is not granted by default and requires you to authorize it manually in your device settings.
With this permission, the Application may access:
- App usage statistics, such as which apps were used, launch frequency, usage duration, and last time used
- Usage patterns and time intervals of app usage
- Other usage-related information made available by Android's UsageStats API
We use this permission solely to:
- Provide app usage analysis, usage time statistics, and app management features
- Help you understand your app usage habits
- Identify apps that may be rarely used, frequently used, or consuming excessive resources
- Support certain cleaning, optimization, or notification features
We do not use this permission to read the content of your messages, emails, photos, videos, or other personal data within third-party apps. Usage statistics are primarily processed locally on your device. If any related information is transmitted, it will be limited to aggregated, anonymized, or diagnostic data for analytics, crash reporting, and service improvement.
This permission is optional and requires your explicit authorization. You can revoke it at any time in your device settings. If you revoke it, features that depend on usage statistics may be unavailable or limited.
