The Rude Awakening

There Is a Spy Living in My Living Room

I'll be honest — I was absolutely floored when I found out what my smart TV has been doing behind my back. There I was, naively flopped on my couch, watching true-crime documentaries in my pajamas at 11 p.m., completely convinced that the only one judging me was my cat. Turns out, a parade of corporations had front-row seats the entire time. My television — the big, beautiful screen I paid good money for — has been quietly taking screenshots of everything I watch, cataloguing my habits, and selling that information to advertisers. I felt genuinely betrayed, like discovering that the friendly neighbor who borrowed your lawn mower has been running a covert surveillance operation out of your garage. Except the neighbor is Samsung, and the garage is my living room, and the "lawn mower" is every questionable show I've ever binge-watched at 2 a.m.

This isn't a fringe conspiracy theory or a sci-fi fever dream. It is the documented, legally contested, industry-wide practice known as Automatic Content Recognition — and if you own a smart TV bought in the last decade, it almost certainly applies to you. The good news: you can fight back. This guide will tell you exactly what's happening, why it matters, and how to shut it down on every major brand.


The Mechanics of Surveillance

What Your TV Is Actually Harvesting

The technology at the center of all this is called Automatic Content Recognition (ACR). Think of it as Shazam for your television screen, except instead of identifying a song so you can enjoy it, it identifies everything you watch so advertisers can follow you around the internet with targeted ads. The TV captures tiny snapshots of whatever is on your screen, generates a compact "fingerprint" of each frame, and matches it against a massive database of known content. The results are then transmitted back to the manufacturer's servers and their advertising partners.

Every 10ms — LG TVs can capture on-screen data locally, according to Texas AG filings

Every 15 sec — LG sends captured data to manufacturer servers, per 2024 UCL study

Every minute — Samsung transmits your ACR viewing data to its servers

And here is the part that truly stunned me: it doesn't matter what you're watching or how. A 2024 peer-reviewed study by researchers at UC Davis, University College London, and Universidad Carlos III de Madrid confirmed that ACR tracks content regardless of source — streaming apps, live cable TV, a Blu-ray player, a game console, or even a laptop connected via HDMI. Your TV is fingerprinting your gaming sessions. Your work presentations. Your home videos. Everything.

"The average user is unlikely to know what ACR is or that they can opt out. Opting out can take as many as six or seven menus to navigate."

— Dr. Anna Maria Mandalari, University College London, via Men's Journal

But ACR is only one layer. Smart TVs also collect:

Voice data — Microphones built into your TV and remote are always listening for wake words, and those audio clips are processed on remote servers. Some TVs have been caught recording ambient conversations even when not explicitly activated.

App usage data — Which apps you open, for how long, and at what time of day. This builds a behavioral profile that extends well beyond what you watch.

Location data — Your IP address reveals your approximate location, and some TVs go further, accessing GPS or nearby Wi-Fi networks to refine it.

Cross-device linking — Some TVs emit ultrasonic beacons — inaudible tones your smartphone picks up — linking your viewing habits to your mobile identity for tracking across every screen you own.

Why do they bother? Follow the money. Vizio's advertising and data licensing revenue surpassed its hardware revenue as far back as 2023. LG's ad business generated nearly $700 million in 2024 alone. Roku reported $3.5 billion in annual ad revenue in 2024, representing 85% of its total income. The dirty secret of the affordable TV industry is that the hardware is subsidized by your data. You aren't just buying a television — you're entering into an unspoken agreement to be surveilled. And in December 2025, Texas Attorney General Ken Paxton had seen enough: he filed major lawsuits against Samsung, Sony, LG, Hisense, and TCL, calling their ACR practices "invasive, deceptive, and unlawful." Samsung settled in February 2026.


The Bigger Picture

It's Not Just Your TV: Other Smart Home Devices That Are Harvesting Your Data

If you think the TV is the only uninvited guest in your home, brace yourself. The average American household now contains 17 connected devices, according to Parks Associates research, and many of them are quietly building dossiers on you right alongside your television.

Smart TVs

The star of this report. ACR, voice data, app usage, location, and cross-device tracking — often enabled by default and deliberately hard to disable.

Smart Refrigerators

Modern smart fridges track what food you buy, when you eat, and your grocery patterns. Apps linked to smart appliances can collect up to 19 data points, according to a Smart Home Privacy Checker study — comparable to a full consumer profile.

Smart Thermostats

Devices like Google Nest build a detailed map of when you're home, when you're away, when you sleep, and even how many people live in your house. That behavioral data is used for targeted advertising and shared with third-party partners.

Smart Home Hubs & Cameras

Smart doorbells and security cameras have been known to share footage with law enforcement under manufacturer partnership agreements. Smart locks, lights, and plugs all log usage patterns that feed into broader consumer profiles.

Voice Assistants (Alexa, Google)

Amazon's Alexa leads all smart home devices in data collection, capturing 28 out of 32 possible data points — including contact details, exact location, and health-related information — all tied to your personal profile. Google Home trails closely with 22 data points. Both devices are always listening for wake words, and recordings are regularly processed on remote servers.

Robot Vacuums

Newer models from brands like iRobot create detailed floor-plan maps of your home, which have privacy implications that go well beyond cleaning schedules. Some manufacturers have reserved the right to sell or share that mapping data.

The cumulative effect is a surveillance web that covers nearly every room in your home. Your thermostat knows when you wake up; your TV knows what you watched before bed; your voice assistant heard the conversation in between. Together, this data paints an extraordinarily detailed portrait of your private life — and it is extremely profitable for the companies holding the paintbrush.


Take Action

How to Turn It Off: Brand-by-Brand Guide

The steps below will disable ACR tracking, limit ad personalization, and reduce voice data collection on every major smart TV brand. A word of warning: manufacturers occasionally bury these settings deeper with firmware updates, and some settings may reset after an update. It is worth revisiting these menus every few months.

Samsung

Samsung's ACR feature is called Viewing Information Services. Their system can capture viewing data and transmit it to Samsung servers roughly once per minute. Samsung reached a settlement with the Texas Attorney General in February 2026, agreeing to clearer consent disclosures — but the tracking is still on by default everywhere else.

  • Press Home, then go to SettingsSupportTerms & PrivacyPrivacy Choices. (On some 2024–2026 models: SettingsGeneral & PrivacyTerms & Privacy)
  • Select Viewing Information Services and turn it off. This disables ACR tracking.
  • Select Interest-Based Advertising and turn it off.
  • Select Voice Recognition Services and turn it off to stop voice data collection.
  • Scroll to the bottom and enable Do Not Sell or Share My Personal Information.
Pro tip: Samsung's ACR domain is log2.samsungacr.com. If you have a router with a blocklist, adding it provides a network-level backup layer of protection.

LG

LG's ACR system is called Live Plus. The 2024 UCL study found LG TVs transmit captured data approximately every 15 seconds — the most aggressive of the major brands tested. LG is still contesting the Texas lawsuit as of 2026. You'll need to disable multiple settings to fully opt out.

  • Press the gear icon (Settings) on your remote → All SettingsGeneralSystemAdditional Settings.
  • Find Live Plus and toggle it off. This is LG's ACR feature.
  • Back in Settings, go to SupportPrivacy & TermsUser Agreements. Uncheck Viewing Information and Interest-Based Advertising.
  • In the same Privacy menu, look for Do Not Sell My Personal Information and enable it.
  • Also disable the "Who. Where. What?" feature in User Agreements — this allows LG's partner to access your viewing data.
Note: On 2019 and older LG sets, press Settings → All Settings → General → About This TV to reach User Agreements.

Vizio

Vizio has been in regulators' crosshairs the longest. In 2017, the FTC fined them $2.2 million for secretly installing tracking software on 11 million TVs without consent. Today, Vizio (now owned by Walmart) makes more money selling your viewing data than selling the actual televisions. They now ask for consent — but the ask is buried deep in setup.

  • Press Menu on your remote → SystemReset & Admin.
  • Find Viewing Data (may also be labeled Smart Interactivity) and toggle it off. This disables Vizio's ACR.
  • Also in Reset & Admin, find Advertising and disable it to limit ad personalization.
Heads up: Some Vizio models have a slightly different path: SettingsAdmin & PrivacyViewing Data. Look for both if you can't find it.

Onn

Onn TVs — Walmart's house brand — run the Roku operating system. That means your privacy controls are governed by Roku's menus. The good news: Roku's privacy settings are among the more clearly labeled. The bad news: they're off by default and Roku's ad business is enormous — $3.5 billion in annual revenue. Follow the Roku steps below exactly, as they apply equally to Onn TVs.

  • Press Home on your remote → SettingsPrivacy.
  • Select Smart TV Experience → uncheck Use Info from TV Inputs. This disables ACR for cable boxes, game consoles, and HDMI devices.
  • Select Advertising → uncheck Personalized Ads.
  • Select Privacy Choices → check Do Not Sell or Share My Personal Information and Limit Use of Sensitive Information.
  • Select Microphone → set to Never Allow or Prompt if you don't use voice features.

Hisense

Hisense is a special case for a few reasons. First, it makes TVs running three different operating systems — Google TV, Roku, and Amazon Fire TV — so your exact steps depend on which model you own. Second, the Texas AG obtained a temporary restraining order against Hisense in late 2025, halting certain ACR-related data collection in Texas. Third, Hisense is a Chinese-owned company, and the Texas complaints specifically raised concerns that collected data could be subject to China's National Security Law. Check your model's packaging or settings to determine which OS you have, then follow the corresponding steps.

  • Hisense on Google TV: SettingsPrivacyAds → turn off Ad Personalization. Also SettingsPrivacyUsage & Diagnostics → turn off. Then check SettingsPrivacyUser Agreements and opt out of the Hisense User Experience Improvement Program.
  • Hisense on Roku TV: Follow the Onn/Roku steps above exactly.
  • Hisense on Fire TV: SettingsPreferencesPrivacy Settings. Turn off Device Usage Data, Collect App and Over-the-Air Usage, and Interest-Based Ads.
Extra caution advised: Given national security concerns raised by regulators, consider placing Hisense and other Chinese-brand TVs on a separate guest Wi-Fi network to isolate their traffic from other devices in your home.

TCL

Like Hisense, TCL sells TVs running both Google TV and Roku, so your settings path depends on your model. TCL is named in the Texas AG's lawsuits still being contested as of 2026. TCL also has its own layer of data collection on top of whatever platform OS it runs — check for TCL-specific User Agreements during setup.

  • TCL on Google TV: SettingsPrivacyAds → disable Ad Personalization. Also disable Usage & Diagnostics. Then go to SettingsPrivacyUser Agreements and opt out of TCL's User Experience Improvement Program and diagnostic data collection.
  • TCL on Roku TV: Follow the Onn/Roku steps above. Then also check for a separate TCL Terms & Privacy screen — on 2025 TCL sets, this appears after initial Roku setup and includes TCL-specific data collection options you can decline.
  • Under TCL's privacy policy, you also have the right to request a copy of all data collected about you, and to request its deletion — contact TCL's privacy team to exercise this right.

Roku

This section covers Roku's own branded TVs and streaming sticks (Roku Express, Roku Streaming Stick, Roku Ultra, etc.). If you have a TCL, Hisense, Onn, or other brand that runs Roku OS, the steps are largely the same. Roku is the heavyweight of the smart TV advertising world — its ad revenue makes up 85% of the company's total income. By default, it shares your data with its partners the moment you turn it on.

  • Press HomeSettingsPrivacySmart TV Experience.
  • Uncheck Use Info from TV Inputs to disable ACR. This also automatically disables Enable Auto Notifications.
  • Go back to PrivacyAdvertising → uncheck Personalized Ads and reset your advertising ID.
  • Go to PrivacyPrivacy Choices → check Do Not Sell or Share My Personal Information and Limit Use of Sensitive Information.
  • Go to PrivacyMicrophone → set to Never Allow or Prompt.
Watch out: Roku has been known to re-prompt users to re-enable ACR settings after certain updates, presenting it as an "enhanced experience" opt-in. Check your settings after any major firmware update.

Hiro

Hiro is a smaller, budget-focused TV brand with a limited presence in the US market. Because Hiro TVs don't run a single proprietary smart TV OS, privacy settings vary significantly by model — some run Android TV, others use simpler proprietary systems. Major tech publications have not specifically documented Hiro's data practices in the same detail as the large brands.

  • If your Hiro TV runs Android TV: Go to SettingsDevice PreferencesUsage & Diagnostics and turn it off. Then SettingsDevice PreferencesAboutLegal InformationAds → select Delete Advertising ID.
  • Look in SettingsPrivacy for any option labeled ACR, Viewing Data, Smart TV Experience, or Content Recognition and disable it.
  • Disable any built-in voice assistant or microphone access you don't actively use.
Nuclear option: For any TV brand where settings are unclear or you simply don't trust the opt-outs to hold, the most effective solution is to disconnect the TV from Wi-Fi entirely and use a separate streaming device (Apple TV, a dedicated Roku stick, or Amazon Fire Stick) where you control the privacy settings independently. No internet connection = no data transmission.
