Millions of internet-connected Amazon devices around the country will be connected to the company’s Sidewalk network starting Tuesday, despite privacy concerns.

The internet-sharing network connects nearby devices via Bluetooth and radio frequencies, allowing them to stay connected to the internet via other Sidewalk-enabled devices even if disconnected from home wireless networks.

The network has been available for Ring Spotlight and Floodlight cameras since last year. Starting Tuesday, most Echo devices will have the feature activated, while Tile trackers will connect on June 14.

Users have the option to opt-out, and internet searches for Amazon Sidewalk turn up dozens of articles on how to do so.
