CM Cleanmaster is a utilities suite for Android that can help protect and optimize your device.

CM Cleanmaster provides a lot of tools in a single package, and it can help you optimize your Android smartphones and tablets as well as protect them and the content you store on them. One way it protects you is with an antivirus engine that can sniff out, isolate and eliminate numerous threats. It uses a leading-edge engine that’s well-respected in the industry, and protection is multilayered.

A safe-browsing mechanism works with any web browser you choose to use. It provides real-time protection against malicious websites as well as various kinds of trackers. It has a no image mode so that you can surf faster and with less data usage. All browsing data can be automatically destroyed upon exit, and anything you download goes into your vault. The App Vault locks images, messages and all other files away from children and prying adults.

CM Cleanmaster optimizes your Android device by cleaning it of files you no longer need as well as caches that have grown overly large. You can run this operation on demand or set it to run on an automated basis. The process will look for unused files, including those left behind by apps no longer on the device. This app can also help you uninstall other apps so that no residual files are left behind. Residual files are one of the biggest causes of storage bloat on Android devices. Note that this app can’t recover files that it’s deleted, so you have to be careful since it is possible for it to identify a file you actually do need as unnecessary.

  • READ_CONTACTS: Allows an application to read the user's contacts data.
  • READ_EXTERNAL_STORAGE: Allows an application to read from external storage.

If you don't request this permission, you will not receive the broadcast at that time.
