Roku TV owners are missing a privacy setting that tracks everything you watch — here's how to turn it off
Most smart TV owners diligently check their security and privacy settings, but one hidden option often goes unnoticed. It's called ACR (Automatic Content Recognition), and it's enabled by default on Roku TVs and Roku streaming devices. This feature monitors what you watch through any connected source — over-the-air antenna, cable box, game console, Blu-ray player, or any other HDMI input, including external streaming sticks.
ACR doesn't just track the channels you tune into. It analyzes the genres of content you watch, the ads displayed (including how long you view them), and even the specific device feeding the signal — be it a cable box, a gaming system, or a streaming stick. For example, if you're watching Prime Video or Disney+ on a Fire TV Stick, Apple TV, or an Android TV device plugged into the Roku TV, the system still captures the video and audio fingerprint of that content. It records genres, dates, times, app names, channel numbers, and viewing duration.
This data is sent to Roku's advertising system and shared with third-party partners to build a detailed profile of your viewing habits. That profile is then used to serve targeted ads while you watch content on the TV. The collection happens in the background without any visible notification, making it easy to miss unless you dig into the settings.
To disable ACR on a Roku TV, navigate to Settings Privacy Smart TV Experience, then uncheck the box labeled "Use info from TV inputs." This stops the TV from sending data about what you watch on connected devices. On standalone Roku players or streaming sticks, go to Settings Privacy Advertising, and look for an option to limit ad tracking or disable ACR. The exact wording may vary slightly by model and firmware version.
Disabling ACR does not affect the normal operation of streaming apps or over-the-air TV. It only prevents the TV from harvesting and sharing viewing data from external inputs. For users concerned about privacy, this is a simple but effective step to reclaim control over what your smart TV knows about you.
