The gadgets that could be SPYING on you and sending your data to China

Experts from Which? rated popular smart devices across six categories.

These included consent consent, transparency, data security, data minimisation, trackers, and data deletion.

Their findings reveal that several popular air fryers can listen in to your conversations.

Xiaomi app linked to its air fryer connected to trackers from Facebook, Pangle (the ad network of TikTok for Business), and Tencent (depending on the location of the user), while the Aigostar and Xiaomi app wanted to know the user's gender and date of birth.

Meanwhile, several smart speakers are 'stuffed' with trackers.

Which? tested the Bose Portable Home Speaker, Amazon Echo Pop , and Google Nest Mini (Second Gen) Bose's speaker and app was found to take the fewest upfront phone permissions of the three devices tested.

Bose speaker also scored poorly on how it secured customer consent for data tracking.

Amazon and Google accounts needed to use the Echo Pop or Nest Mini do not give users an easy option to opt out of trackers.
