I take privacy extremely seriously (specially since I am also a user of GVMax). GVMax will not make any of your information available to anyone. All information is store encrypted. Your SMS and Voicemail are not analyzed in any way and are kept in GVMax for only a few seconds while they are being processed.
The only information I collect is statistical information such as the number of SMS you have received. This information is used to display statistics on your account page and as input to aggregate statistics such as the total number of SMS processed by GVMax.
