Smart TVs: Methods to protect privacy and limit data collection

Smart TVs utilize various technologies to collect user data, which can be used for targeted advertising or sold to third parties. A primary method is Automatic Content Recognition (ACR), a technology that identifies visual and audio content being watched, including material from streaming apps, broadcast channels, or connected devices like game consoles and HDMI sticks.

To mitigate privacy risks, users can take several steps. Disabling ACR is a critical first step, though manufacturers often hide these settings deep within privacy menus. On platforms like Amazon Fire TV, users can navigate to privacy settings to turn off ACR, device usage data, and over-the-air data. Other methods include using a VPN to encrypt internet connections and reviewing app permissions to limit access to personal information.

While some users employ advanced software projects like CleanYourTV, Projectivity Launcher, or DumbTV to overhaul interfaces and remove tracking, these more complex methods are not strictly necessary for improving privacy. Additionally, concerns have been raised regarding microphones on certain models that may remain active even when the screen is off.
