A study by the English publication Which? has shown that some “smart” household devices collect excessive amounts of data about their owners and even share this data with third parties. For example, some air fryers request access to the phone's microphone, and TVs want to know the exact location of users.
Some air fryer models, such as Xiaomi and Aigostar, require access to the phone's microphone and user location data, although this is not related to their work. Xiaomi transfers data to trackers Facebook, TikTok and Tencent. These fryers also send user information to servers in China, as stated in the privacy policy.
