If users think an app is accessing something that it shouldn’t, they have the option of blocking URLs or port numbers accessed with it. Users can also set firewall rules for individual apps and even provide connection history for apps on the phone. WhisperMonitor also comes bundled with WhisperCore, a device-level encryption app for Android storage, including the SD card.
So if you think that your phone is sending out data that it shouldn’t, or you want some extra protection for the files on your phone, head over to the WhisperSystems website to download WhisperMonitor for your Android phone.
