Discover and control what data is collected about you by Internet of Things (IoT) technologies. The IoT is everywhere. It consists of a myriad of devices and technologies that collect data about us - from cameras with facial recognition, to smart speakers that record what we say, or sensors that track our whereabouts. The IoT Assistant app helps you discover what data is being collected about you and how it is used. This includes who is collecting it, who it is shared with, and whether there are any privacy controls. New privacy regulations around the world require people who deploy IoT technologies to disclose their data collection and use practices and to also give us some control over these practices such as opting in or out of them. The IoT Assistant app provides users with a single interface through which they can discover IoT data collection around them and access available privacy controls. The IoT Assistant app also allows you to receive customized notifications about data collection and use practices you want to be notified about and control the frequency of these notifications. An IoT portal associated with the app (https://www.iotprivacy.io) is available to also publicize the presence of IoT technologies ("IoT resources") collecting our data, whether you are the administrator controlling that technology or a volunteer contributor. Once you have defined an entry for an IoT technology through our portal, IoT assistant app users can discover this IoT technology and its data collection and use practices.
