AliExpress has been accused of using WebAudio API to play inaudible sound waves, creating unique digital fingerprints of devices for tracking purposes. This was discovered when users' Bluetooth headphones refused to switch from their computers to their phones while browsing the site. The scripts also measure other device parameters like mouse clicks and send a general device identifier to Alibaba servers. The practice has raised privacy concerns among users.
