Most people think of a smart TV as nothing more than a bigger screen for Netflix, YouTube, Disney+, live sports, and movies. In reality, today's smart TVs have evolved into sophisticated connected devices that can collect a surprising amount of information about what you watch and how you use your television every day.
Whether you own a Samsung, LG, Sony, TCL, Hisense, or another popular brand, your TV may be recording the apps you open, the content you watch, how long you spend viewing certain programs, and even how you interact with specific features. In many cases, this information can be used to build advertising profiles that help companies deliver more personalized ads across multiple platforms.
One of the most controversial technologies built into many smart TVs is Automatic Content Recognition (ACR). This feature can identify what's playing on your screen by analyzing the displayed content, regardless of whether it comes from a streaming service, a cable or satellite receiver, a gaming console, or another connected device. While manufacturers promote ACR as a way to improve recommendations and personalize the viewing experience, privacy experts have raised ongoing concerns about the amount of data it can collect and how that information may be shared.
Perhaps the most surprising part is that many of these privacy-invasive features are enabled by default during the initial setup process. Most users simply accept the lengthy privacy agreements without realizing how much access they're granting, allowing data collection to continue for years without ever reviewing the settings.
The good news is that protecting your privacy doesn't require technical expertise. In just a few minutes, you can disable many of the most intrusive tracking features without affecting your favorite streaming apps, gaming consoles, live TV services, or the core smart features that make modern televisions so convenient.
In this guide, you'll discover what information smart TVs actually collect, how technologies like ACR work, why advertisers place such a high value on this data, and which privacy settings you should turn off immediately to take back control of your personal information and reduce unnecessary tracking.
What Your Smart TV Actually Collects
Many people assume that smart TVs only collect basic usage statistics. In reality, today's smart TVs can gather much more information than most users realize. Depending on the manufacturer, operating system, and the privacy settings you've enabled, your TV may continuously collect data about your viewing habits, app usage, and even your voice interactions.
Here's the type of information a smart TV may collect behind the scenes:
Viewing activity — Your TV can track the channels you watch, the streaming apps you open, and how much time you spend watching specific content. This may include Netflix, YouTube, live TV, cable or satellite boxes, and even devices connected through HDMI.
Device fingerprinting — Information such as your device ID, IP address, TV model, firmware version, language preferences, and Wi-Fi network details may be collected to uniquely identify your television over time.
App usage analytics — Smart TVs can monitor which apps you use most frequently, how long you stay in each app, and which menus or features you interact with on a regular basis.
Voice assistant data — If voice control or the built-in microphone is enabled, your TV may listen for wake words and send short audio samples to cloud servers for speech recognition.
Cross-device advertising tracking — Some smart TV platforms attempt to link your TV activity with your smartphone, tablet, or web browser to create a more comprehensive advertising profile across multiple devices.
ACR: The Biggest Privacy Problem on Smart TVs
The technology responsible for much of this tracking is called Automatic Content Recognition (ACR). It works by analyzing small visual or audio fingerprints taken from the content displayed on your screen and comparing them with large media databases to determine exactly what you're watching.
What makes ACR particularly controversial is that it isn't limited to streaming apps. It can also recognize content coming from:
- HDMI devices
- Gaming consoles
- Blu-ray players
- Cable and satellite receivers
- Live television broadcasts
In other words, your TV may still recognize the exact movie, TV show, sporting event, or game you're watching even when the content isn't coming from a built-in streaming app.
The information collected through ACR is commonly used to improve content recommendations, generate viewing statistics, build behavioral profiles, and, in some cases, share data with advertising and analytics partners.
One of the best-known ACR platforms is Samba TV, although many manufacturers offer similar technology under different names in their privacy settings.
How to Disable Tracking on Samsung TVs
Samsung smart TVs running Tizen OS include several privacy and advertising features that are enabled by default. To minimize tracking, you'll need to disable a few separate options within the privacy settings.
On Samsung TVs released from 2022 onward, some of these settings may be located under Settings → All Settings → General & Privacy.
How to Disable Tracking on LG TVs
LG smart TVs running webOS include a tracking feature called Live Plus, which works similarly to Automatic Content Recognition (ACR). They also use advertising identifiers and personalized recommendation features that can be disabled individually for better privacy.
How to Disable Tracking on Sony / Android TV
Sony TVs running Android TV or Google TV include both Sony privacy features and Google's advertising services. To maximize your privacy, it's recommended to disable both sets of tracking options.
How to Disable Tracking on TCL / Roku TVs
Roku OS is well known for its strong focus on advertising and viewer analytics. Many TCL TVs running Roku OS include Automatic Content Recognition (ACR), advertising identifiers, app usage analytics, and personalized advertising features that are enabled by default.
Go Further: Block Smart TV Tracking at the Router Level
Even after disabling your TV's built-in privacy settings, it may still attempt to connect to analytics, telemetry, and advertising servers in the background. One of the most effective ways to reduce this traffic is to block those connections at the network level using your router or a DNS filtering service.
One of the most popular solutions is Pi-hole, a DNS-based ad and tracker blocker that runs on a Raspberry Pi or another low-power device. Once configured, it can block thousands of known advertising and tracking domains before your smart TV is able to communicate with them.
Many advanced users combine Pi-hole with additional privacy tools, including:
- OpenWrt-based routers
- ASUS routers running Merlin firmware
- Synology router DNS filtering
- AdGuard Home
- NextDNS custom filtering
If you're looking for a simpler solution, you can also change your TV's DNS settings to a privacy-focused provider such as:
- 9.9.9.9 — Quad9
- 1.1.1.2 — Cloudflare Malware Protection
While these DNS providers won't block every advertising tracker, they can still improve your privacy by blocking known malicious domains, phishing infrastructure, suspicious telemetry endpoints, and some background connections commonly used for analytics and device tracking.
After reviewing the privacy settings on several smart TVs over the years, one thing quickly became obvious: disabling the tracking features isn't the difficult part—finding them is. Many manufacturers spread privacy controls across multiple menus, hide them inside lengthy user agreements, or place them under separate advertising, analytics, and AI-related settings that most users never think to check.
During a recent test on an LG webOS TV, disabling Live Plus, personalized advertising, usage analytics, and voice recognition took less than five minutes. Once those features were turned off, there was no noticeable difference in day-to-day use. Streaming apps continued to work normally, software updates remained available, and the TV performed exactly as it had before.
Netflix, YouTube, Disney+, Plex, live TV channels, and gaming consoles all worked without interruption. Picture quality stayed the same, navigation remained smooth, and none of the smart TV features most people rely on every day were affected.
The only real difference was the amount of information being shared. Instead of continuously sending viewing habits, advertising identifiers, and usage data to analytics platforms, the TV became significantly more privacy-friendly without sacrificing convenience or functionality.
The biggest takeaway is that improving your privacy doesn't mean giving up smart features. In most cases, it simply requires spending a few minutes reviewing your TV's privacy settings and disabling the options designed for advertising, user profiling, and viewing analytics rather than features that genuinely enhance the viewing experience.
If you're setting up a new television, pay close attention whenever you come across options related to personalized recommendations, advertising, voice recognition, content recognition, or enhanced viewing experiences. These are often the settings responsible for most of the background tracking that takes place on a smart TV.
💡 Final Thoughts
Smart TVs have evolved into powerful connected devices that offer incredible convenience, but that convenience often comes with a hidden trade-off: data collection. From viewing habits and app usage to advertising preferences and content recognition, many modern televisions collect far more information than most owners realize.
The good news is that protecting your privacy doesn't require disconnecting your TV from the internet or giving up the streaming services you enjoy. In most cases, adjusting just a handful of settings can dramatically reduce the amount of data your television collects and shares.
Disabling ACR, personalized advertising, voice recognition, and optional diagnostic reporting usually takes no more than a few minutes. Those small changes can make a significant difference to your privacy without affecting Netflix, YouTube, Disney+, gaming consoles, firmware updates, or the smart TV features you rely on every day.
As smart home devices become increasingly connected, reviewing your privacy settings regularly is becoming just as important as keeping your software up to date or securing your Wi-Fi network. Taking control of these settings helps ensure that your television works for you—not advertisers or data brokers.
The next time you set up a new smart TV, take a few extra minutes to review the privacy settings. It's one of the easiest ways to reduce unnecessary data collection and better protect your privacy for years to come.
