Yes, they can definitely track you and your location. That's why we warn ppl not to use it from INSIDE Iran. According to the unofficial monitoring laws every ISP has to give a log of the users, their browsing history and their telephone numbers to government authorities. (I got this news from two independent sources who work for Iranian ISPs). A firewall cannot protect your identity, but a proxy or anonymity network (Tor, JAP, VPN, etc.) can protect you. However it's not recommended because: first they are slower than direct connection. Second: it consumes the bandwidth that can help our Iranian sisters and brothers for passing the government filtering system. Therefore only use this program if 1: you live OUTSIDE Iran, 2: You have a hi-speed connection (>1Mbps, at least 10Mbps is recommended), 3: Your ISP doesn't impose traffic limitations. Thanks for helping Iranians, Good luck!
