Smart household appliances such as refrigerators, washing machines, and dishwashers actively collect usage data and transmit it to manufacturers on a regular basis. Consumer Reports found that major appliance brands send between 3.4 and 19 megabytes of data weekly, encompassing operational patterns, personal details like postal codes and birthdates, and intimate family information including grocery purchases, consumption habits, and laundry frequency.

Whilst manufacturers typically encrypt this collected data and cite general purposes like product improvement and personalised marketing, the specifics of data sharing remain opaque. Companies routinely share information with subsidiaries, affiliates, and third-party business partners without clearly disclosing what data transfers occur or why. Consumers concerned about privacy can examine company privacy policies to understand collection practices, though manufacturers often use deliberately vague language that obscures the true scope and use of personal information.
