PhoneTools

PhoneTools is a professional mobile assistant that helps you free storage, manage apps, secure sensitive apps, and find your device. Key features include a Junk Cleaner for removing temporary files, cache and residual files; an App Manager to list and batch-uninstall apps; Deep Cleaning and Clear Memory tools to optimize performance; a Find Phone feature to locate misplaced devices; and a built-in QR Code scanner.

For app security PhoneTools uses the AccessibilityService API to implement App Lock. This permission enables monitoring app launches, showing an unlock interface when a locked app is opened, and preventing unauthorized access. We only use accessibility access to provide the lock functionality, do not collect personal interaction data, and you can disable the permission anytime in your device's Accessibility settings. Note that enabling this service may slightly increase background battery usage.
