Clean Master is a free utility and tools application available for Android devices. Developed by SEE Tsun Fook, this app is designed to help users better manage their phones while saving storage space.

One of the main features of Clean Master is its ability to clean your photo library. It can find and remove similar, old, and poor quality photos, such as those that are too bright, dark, or unfocused. Additionally, it offers file compression options, allowing you to reduce the file sizes of your photos. You can choose from Low, Moderate, High, and Aggressive compression levels, and the app also provides the option to move the original photos into cloud storage. Furthermore, Clean Master allows you to delete photos from private chats, ensuring your privacy.

It's important to note that Clean Master may request access to your device's location data in order to automatically trigger certain profiles based on your location. However, the app will ask for permission before using this data, ensuring your privacy and control over your personal information.
