Germany has banned the sale of smartwatches that allow parents to keep tabs on their children, saying the devices go against the country's surveillance laws.
Germany's Federal Network Agency advised parents to destroy the watches and said it has taken action against firms that sell the devices.
The watches are aimed at children between the ages of 5 and 12.
"Via an app, parents can use such watches to secretly listen to a child's environment. They are to be seen as a prohibited transmitter," agency president Jochen Homann said.
"Our investigation has also shown that parents have used the watches to listen to teachers in the classroom."
The smartwatches include a SIM card and have a limited telephone function that can be controlled through an app, meaning they can potentially be used to listen in on conversations, which violates German law.
The agency in February banned the distribution of a talking doll, citing similar concerns.

Vibrating Grizzly Feeders are engineered to combine the functions of feeding and scalping into one unit, reducing the cost of having two separate units. Vibrating Grizzly Feeders are mainly used in a primary applications feeding a primary crusher. The Vibrating Grizzly Feeder provides a continuous feed rate under a variety of loading and material conditions. Vibrating Grizzly Feeders are designed to take heavy shock loads from trucks, shovels and loaders. This type of feeder can be used in quarries, recycling, industrial processing, mining, and sand and gravel operations, as well as in a wide range of processing industries.
How Vibrating Grizzly Feeders Work
The Vibrating Grizzly Feeder consists of a pan section at the feed end to receive and start segregating the material. The discharge end consists of a grizzly section with openings that allow the undersized material to pass before discharging into the crusher. The feeder is mounted on springs and vibrated via a mechanism located underneath the feeder pan, protecting it from misfed material that fails to reach the feed hopper. The vibration force is angled to the feeder, pointing toward the discharge end. This action of the vibrator forces the material toward the discharge end while segregating the material, causing the finer particles to move toward the bottom of the load.
As the material travels to the grizzly section, the finer material settles to the bottom and passes through the openings in the grizzly. This bypassed material decreases the amount of material going into the crusher, reducing the size of the crusher required as well as the wear inside the crusher. The bypassed material can be combined with the material going through the crusher on the under conveyor. This prescreened material protects the under conveyor from the impact of the material exiting the crusher. The prescreened material can be segregated as a product, or it can be discarded if the fines in the material are a contaminate.
