Two women filed a proposed class-action lawsuit on Monday, December 5, in the United States District Court for the Northern District of California against Apple, the makers of AirTags.

Airtags are a small Bluetooth-enabled devices designed to track personal belongings. The suit accuses the company of failure to introduce measures to combat abuse of the technology as stalkers have and continue to use AirTags to track people. Both claimed their ex-partners did just that.

Lauren Hughes, one of the plaintiffs, learned she was being tracked in August 2021 after ending a three-month relationship. According to The New York Times, Hughes’s stalker sent her threatening voicemails and made abusive posts on social media. She moved to a hotel after receiving plants from her stalker at her doorstep.
