Companies are also now offering to pay users in exchange for tracking their online activity. Depending on the type of tracking and the depth, this poses a threat to privacy, but most online services are already performing tracking of some kind. In order to protect themselves, consumers should consider how free apps make money and whether or not this exploits them. Be careful when giving permission to certain apps that ask for location or download a tracker blocker. It’s always a good idea to read the permissions before you use apps.
