Users frequently connect to hotspots to enjoy free-of-cost service (as opposed to mobile data connections). A hotspot may have a captive portal, which usually consists of a web-page that allows users to choose their preferred language and confirm acceptance for the terms of service. The captive portal is used to communicate hotspot privacy policies, collect personal identification information such as name and email for future communications, and authenticate guests if needed (e.g., by asking the user to login to their social media sites). Then, if the user accepts the hotspot's policies, she is connected to the internet and her web browser is automatically directed to load a landing page (usually the service provider's webpage). We analyze tracking behaviors and privacy leakage for the following hotspots.
