DS Talk Privacy Policy
This application does NOT access any information on your Android device and it does NOT require any redundant permissions.
The only permissions really needed are the following:
RECORD_AUDIO and INTERNET are obviously required to make voice calls via Internet by using VoIP (Voice over IP) technology. RECORD_AUDIO allows to hear your voice and INTERNET is needed to send packets with your voice to a remote party.
ACCESS_NETWORK_STATE allows the application to know about the fact you are using wifi / mobile data and so act regarding that (check if your contacts are available and allow your contacts to know that you're available).
WAKE_LOCK is required to keep the device active with dimmed screen during a call.
