Honeygain allows users to make passive income online by sharing their internet connection. The app accesses a user’s IP address and, according to its website, uses that connection to “provide third-party businesses with stable connectivity for a number of initiatives.” Honeygain’s website goes out of its way to assure users that its operations are safe and above-board. However, it releases little-to-no data about which companies are using the data connections that users sell or what kind of business is being conducted.
