If you need help, use "Write to us" in the app's settings or visit the website:

This app does not control your voicemail service. If your blocked calls are being sent to voice mail, try another blocking method or use Google Voice. You can simulate a disconnected message by forwarding busy calls to a number that doesn't exist.

OUTGOING CALL permissions are needed for hidden mode, using the dialer to enter a password.

ACCOUNTS are needed for Google Contact Groups.

SEND SMS needed for auto replies and SMS routing.

INTERNET ACCESS is for licensing and the "Write to us" feedback tool.

LOG DATA is only sent with your permission via the "Write to us" menu item in Settings. You do not have to send anything if you don't want to.
