You Smart Tv is Spying on you - How to turn it off
Auto content recognition, or ACR, found on all major brands, analyzes what is appearing on the TV screen, including what comes through HDMI, so it can determine what you're watching and use that information for advertising, audience measurement, and profiling.
The good news is you can turn it off.
Look in your TV’s privacy settings for terms like:
Live Plus (LG)
Viewing Information Services (Samsung)
Viewing Data (Vizio) Smart TV Experience / “Use Info from TV Inputs” (Roku TVs, including many TCL/Hisense models running Roku OS)
Automatic Content Recognition (Amazon Fire TV / Fire TV televisions)
Enhanced Viewing Service (Hisense)
Samba Interactive TV (certain Sony Bravia models)
Automatic Content Recognition / ACR (TCL models using TCL’s own services; exact menu varies by operating system)
Find yours. And turn it off.
