Smart TVs track what you watch using hidden settings. Learn how to turn off data collection and ad tracking on Samsung, LG, Roku, Sony, and Vizio TVs.

| From Samsung to LG and Roku, smart TVs use built-in tracking to collect viewing data. Hereโs what it is, why it matters, and how to turn it off. |
Smart TVs from Samsung, LG, Roku, Vizio and others arenโt just screens anymore. Theyโre internet-connected computers that collect detailed information about what you watch โ and sometimes how you watch it โ to tailor ads, power recommendations and sell viewing data to advertisers. Thatโs a big deal for privacy, and many of these tracking systems are turned on by default.
Whatโs Actually Being Collected?
Most modern โsmartโ TVs use Automatic Content Recognition (ACR) technology. ACR uses audio and video fingerprints to identify whatโs on your screen โ even if youโre watching via HDMI from a gaming console, streaming stick or Blu-ray player โ and sends that information back to servers for analysis.
ACR isnโt just about apps like Netflix or Hulu. On many TVs, it works behind the scenes to track every show, ad, and game you watch, regardless of source. Add in voice assistants and advertising IDs, and your TV can collect far more than you realize.
Why This Matters
Hereโs what the data can include:
-
Your viewing habits (what you watch and when)
-
Content screenshots and audio fingerprints
-
Ad-response behavior (did you watch the ads?)
-
Device and network identifiers used to build profiles
That data can be used for targeted ads, sold to third-party data brokers, or aggregated to create detailed behavioral profiles โ and often without your explicit awareness. Thatโs why privacy advocates liken smart TV data collection to surveillance technology on your living room wall.
