Your smart TV is running a feature you almost certainly never turned on. Smart TV ACR privacy is one of the least understood settings in the average home — and the gap between platforms is wider than most people realize.
ACR stands for Automatic Content Recognition. It works like Shazam, but instead of identifying songs on request, it runs continuously in the background — capturing screenshots of whatever is on your screen and matching those frames against a content database. Your viewing history is then packaged and sold to advertisers, shared with third-party data brokers, or used to serve you targeted ads across your phone, laptop, and other connected devices. Crucially, it doesn’t matter what you’re watching or where the signal comes from. If your cable box, game console, or Blu-ray player is connected via HDMI, ACR tracks that too.
In December 2025, Texas Attorney General Ken Paxton filed separate lawsuits against Samsung, LG, Sony, Hisense, and TCL, calling ACR “an uninvited, invisible digital invader” and describing Samsung TVs as “a mass surveillance system.” His office obtained temporary restraining orders against Hisense and Samsung, halting certain ACR data collection practices in Texas. The lawsuits argue that ACR practices likely violate state consumer protection law — the same statute used to extract a $1.4 billion settlement from Meta in 2024.
The legal argument is straightforward: most users have no idea this is happening, because the settings are buried, the names are opaque, and the default is always on.
Here is how the six major smart TV platforms compare, from most invasive to most private.
ACR: The Feature Your TV Turned On Without Asking
Before comparing platforms, it helps to understand what you’re actually dealing with. ACR doesn’t just log the Netflix shows you watch. According to research published at the 2024 ACM Internet Measurement Conference, ACR tracking on major smart TV platforms is largely agnostic to input source — meaning the camera-style fingerprinting of on-screen content occurs whether you’re using a built-in streaming app, a cable box, or an external device plugged into an HDMI port.
The tracking operates at the operating system level, not the app level. That distinction matters because it means your streaming app’s privacy policy is mostly irrelevant. Even if Netflix doesn’t share your viewing data, the TV’s own OS may be taking screenshots of whatever Netflix is displaying and sending those fingerprints to a separate server you’ve never agreed to share data with.
Paxton’s lawsuit claims some ACR systems capture screenshots as frequently as every 500 milliseconds. Whether or not that figure holds up to legal scrutiny, independent research confirms that ACR polling happens at high frequency and that the data volume is substantial.
Samsung Tizen: ACR by Another Name
Samsung uses a proprietary ACR implementation integrated into its Tizen operating system. The setting is called “Viewing Information Services” — not ACR — which is part of why so many users never find it.
To disable it on a 2025 Samsung TV: go to Settings → Support → Terms & Policy → Viewing Information Services and toggle it off. On older models, look under Smart Hub → Settings → Support → Terms & Policy → SyncPlus and Marketing. Samsung also hides interest-based advertising controls in the same Terms & Policy section rather than under a Privacy menu, which is a deliberate design choice that buries the controls.
The Texas lawsuit specifically obtained a temporary restraining order against Samsung, which means a court agreed there was sufficient reason to halt certain data collection practices while the case proceeds. That’s not a finding of liability, but it is a meaningful signal that the default behavior crosses legal lines under at least one state’s interpretation.
Privacy verdict: High collection by default. Disabling requires navigating legal policy menus, not settings.
LG webOS: Live Plus Is the Setting to Kill First
LG’s ACR feature is called “Live Plus.” When enabled — and it defaults to on — Live Plus identifies content on screen and uses that data to serve personalized ads and content recommendations. LG’s own description of the feature says it may use the data to “provide you with an enhanced viewing experience and personalized services including content recommendations and advertisements.”
Disable it under Settings → All Settings → General → Live Plus and toggle it off. Also check Settings → All Settings → General → About This TV → User Agreements and disable Viewing Information and Interest-Based Advertising separately.
LG was also named in the Texas lawsuits. Like Samsung, LG’s ACR operates across HDMI inputs — your gaming console’s output is fair game.
Privacy verdict: High collection by default. Two separate settings require disabling, not one.
Roku: The Most Transparent — and Still Invasive
Roku is unusually straightforward about what it collects, which makes it easier to evaluate — and harder to defend. In its published ACR policy, Roku explicitly states that when ACR is enabled, it collects viewing data from antenna inputs and all HDMI-connected devices, and may share that data with third parties for measurement and advertising purposes. It also notes that if you disable ACR after having it enabled, previously collected data is retained.
The setting path: Settings → Privacy → Smart TV Experience → Use Info from TV Inputs → uncheck. This also disables the “More Ways to Watch” recommendation feature, which is the consumer-facing benefit Roku uses to justify the tracking.
Roku’s business model is built on advertising — the company generates substantial revenue from ad sales, which is funded directly by viewing data. Disabling ACR doesn’t stop Roku from collecting data about which apps you use or what you stream through Roku channels. That requires separate steps under Privacy → Advertising → Limit Ad Tracking and Privacy → Privacy Choices.
Privacy verdict: Moderately invasive. Unusually transparent documentation, but multiple settings required and some data collection persists regardless.
Google TV: Google’s Data Machine, Now on Your TV
Google TV — used in Sony, TCL, Philips, and Hisense models — occupies a nuanced position. Google itself says the Google TV platform doesn’t use ACR to capture on-screen content. However, the individual TV manufacturer may implement their own ACR layer separately, and Google’s own data collection from the platform is extensive.
Google collects data from every app, browser, and device you use to access Google services. On a Google TV, that means your TV searches, YouTube viewing, content browsing, and purchase activity are all folded into your Google account’s data profile — which is used across advertising systems that span your phone, laptop, and any other device signed into the same account. There’s no meaningful opt-out of Google’s core data practices if you want smart TV functionality.
Disable what you can: Settings → Privacy → Usage & Diagnostics → off. For brand-specific ACR (Sony, TCL): check Settings → Device Preferences → Samba Interactive TV or Settings → Display & Sound → Intelligent Settings depending on model.
Privacy verdict: Moderate-to-high collection. Platform-level Google tracking is unavoidable; brand ACR is a second layer on top.
Amazon Fire TV: The Honest Outlier
Amazon Fire TV is the one major platform where ACR as traditionally defined is not used. Amazon has publicly stated that it doesn’t use ACR to track content from cable boxes or other HDMI-connected devices — a meaningful distinction that sets it apart from every other platform in this comparison.
That said, Amazon does collect data on what you watch through antenna inputs and through streaming apps available on Fire TV. And if you watch anything on Prime Video, Amazon has complete visibility into that viewing activity. The absence of HDMI-based ACR tracking is a genuine differentiator, but Fire TV is still an advertising platform whose business model depends on knowing what its users watch.
To tighten privacy on Fire TV: Settings → Preferences → Privacy Settings → disable “Collect App and Over-the-Air Usage Data” and “Interest-Based Ads.” These don’t eliminate data collection but substantially reduce the advertising profile Amazon builds.
Privacy verdict: Lower collection than Samsung, LG, or Roku. No HDMI ACR tracking. Still collects substantial viewing and usage data.
Apple TV 4K: No ACR, Full Stop
Apple TV 4K is the only major streaming platform that does not use ACR at all. Apple has confirmed this explicitly, and independent analysis by Ars Technica and PIRG supports the claim. “Apple’s primary business model isn’t dependent on selling targeted ads, so it has somewhat less incentive to harvest and monetize incredible amounts of your data,” RJ Cross, director of PIRG, explained in Ars Technica’s assessment of the platform.
Apple does collect some data: search terms, viewing history within the Apple TV app, and usage analytics. That data is processed through differential privacy techniques, which means it’s anonymized before being used in aggregate. Third-party apps on Apple TV must request tracking permission explicitly under tvOS — the same model as iOS — and you can deny all such requests globally under Settings → Privacy → Tracking → Allow Apps to Request to Track (set to off).
The catch: Apple TV is a streaming box, not a TV. You still need a physical television to use it, and if that TV has ACR enabled, the TV’s own OS will continue taking screenshots of whatever Apple TV is displaying. The correct configuration is Apple TV as your streaming device plus ACR disabled at the TV level.
Privacy verdict: Lowest data collection of any major platform. No ACR. Data collected is anonymized and used in aggregate.
The Comparison Table
| Platform | ACR Used | HDMI Tracking | On by Default | Data Sold to Third Parties |
|---|---|---|---|---|
| Samsung Tizen | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
| LG webOS | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
| Roku | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
| Google TV | ⚠️ Platform: No / Brand: Varies | ⚠️ Varies | ✅ Yes | ✅ Yes |
| Amazon Fire TV | ❌ No (HDMI) | ❌ No | ⚠️ Partial | ⚠️ Partial |
| Apple TV 4K | ❌ No | ❌ No | N/A | ❌ No |
The practical hierarchy: Apple TV 4K is the clear winner on privacy. Fire TV is the best option among platforms built into TVs. Samsung, LG, and Roku are functionally equivalent in how aggressively they collect viewing data by default — the main difference is how transparent they are about it (Roku is most transparent; Samsung is least).
What I Actually Found
Most smart TV privacy guides tell you to disable ACR and call it done. The more important finding from looking at this closely is that disabling ACR on the TV doesn’t disable data collection from the streaming apps running on that same TV — and most people treat those as the same thing when they’re not.
Turning off Samsung’s “Viewing Information Services” stops Samsung from fingerprinting your screen. It does nothing to limit what Netflix, YouTube, or any other app collects directly from your usage within their own platforms. If your goal is genuine privacy reduction rather than just stopping one specific data flow, you need to treat the TV’s OS and every app running on it as separate tracking systems — because that’s what they are.
The second thing most guides miss: firmware updates regularly reset privacy settings to their defaults. This has been documented on Samsung, LG, and Roku devices. If you’ve taken the time to disable ACR and limit ad tracking, set a calendar reminder to recheck those settings after every major software update. The settings don’t announce themselves when they’ve been changed back.
The data your smart home devices collect about you is rarely visible at the point of collection — and smart TV ACR is one of the clearest examples of that pattern playing out at scale. The Texas lawsuits matter less for what they’ll ultimately achieve legally and more for what they’ve already accomplished: making ACR a household term for the first time since Vizio paid its FTC fine in 2017.
Making the Decision That Fits Your Setup
If you already own a smart TV and aren’t replacing it: disable ACR at the OS level using the steps for your platform above, then recheck after the next firmware update. Layer a streaming stick like Fire TV or Apple TV on top to shift your primary viewing away from the TV’s own OS. A dedicated streaming device combined with a 30-minute smart home privacy audit is the fastest way to substantially reduce your household’s data exposure without replacing any hardware.
If you’re buying a new TV: buy the cheapest display with good picture quality and run Apple TV or Fire TV as your streaming layer. The smart TV platform bundled into your display is a liability, not a feature — and the less you use it, the less it can collect.
Smart TV ACR privacy isn’t a solvable problem at the consumer level as long as the default is on and the opt-out requires navigating legal policy menus. But understanding which platforms are better than others, and why, at least lets you make an informed choice about what’s running in your living room.
What is ACR on a smart TV and why should I care?
ACR stands for Automatic Content Recognition. It’s a technology built into the operating system of most smart TVs that continuously captures screenshots of whatever is on your screen and matches those images against a content database to identify what you’re watching. The data is then used to serve you targeted ads and may be sold to third-party advertisers and data brokers. It operates across all inputs — including cable boxes and game consoles connected via HDMI — not just the TV’s built-in apps. Most users are unaware it’s running because it’s enabled by default and the settings are buried under legal policy menus rather than standard privacy controls.
Which smart TV platform has the best privacy?
Apple TV 4K is the only major platform that uses no ACR at all. Apple’s business model doesn’t depend on advertising revenue, so it has less incentive to collect and sell viewing data. Amazon Fire TV is the best option among platforms built into TVs — it doesn’t track content from HDMI-connected devices, which sets it apart from Samsung, LG, and Roku. Google TV sits in the middle: the platform itself doesn’t use ACR, but individual TV brands (Sony, TCL, Hisense) may add their own ACR layer, and Google’s own data collection across its services is extensive regardless.
Does disabling ACR stop all tracking on my smart TV?
No. Disabling ACR at the OS level stops the TV’s operating system from fingerprinting your screen. It doesn’t affect what individual streaming apps — Netflix, YouTube, Hulu, etc. — collect from your usage within their own platforms. Those apps track separately and have their own data policies. To meaningfully reduce tracking, you need to disable ACR at the TV level and then manage permissions and ad tracking settings within each app individually. You should also recheck your TV’s privacy settings after major firmware updates, as some platforms reset ACR and ad tracking to their defaults automatically.
How do I turn off ACR on a Samsung, LG, or Roku TV?
On Samsung TVs: go to Settings → Support → Terms & Policy and disable “Viewing Information Services.” On LG TVs: go to Settings → All Settings → General → Live Plus and toggle it off, then also disable “Viewing Information” under General → About This TV → User Agreements. On Roku TVs: go to Settings → Privacy → Smart TV Experience and uncheck “Use Info from TV Inputs.” All three platforms enable these features by default, and the setting names deliberately avoid using the term “ACR,” which makes them harder to find.
Why did Texas sue five TV manufacturers over ACR?
In December 2025, Texas Attorney General Ken Paxton filed lawsuits against Samsung, LG, Sony, Hisense, and TCL, alleging they unlawfully collected and monetized consumers’ viewing data through ACR without adequate disclosure or consent. The lawsuits were brought under the Texas Deceptive Trade Practices Act — the same statute used in the $1.4 billion Meta settlement in 2024. Paxton’s office obtained temporary restraining orders against Hisense and Samsung, halting certain ACR data collection practices in Texas while the cases proceed. The complaints also raised concerns that data collected by Hisense and TCL could be subject to China’s National Security Law, which can compel companies to share data with the Chinese government.
