Chrome will soon make it harder for websites to spy on you
A new feature coming to Chrome in the near future will allow users to limit the kind of data certain websites collect about them by blocking access to motion and light sensors on their device.
The feature will alert you if you visit a website that wants to access your sensors. A pop-up window will appear saying “This page is using motion or light sensors” and offers you the choice of allowing access to the sensors or blocking access on a page-per-page basis.
