So you just got a new smart TV, or maybe a Roku or Fire TV ($34 at Amazon) streamer as a holiday gift (maybe from yourself, but who's counting?). Congrats! Whether it was a discounted doorbuster or a , now is a great time to enjoy your big screen.
One thing you might want to consider about any new TV, just like a phone or smart home device, is how it handles your privacy. In many ways, the content you watch on the big screen is watching you back. While most modern TVs aren't tracking you with physical cameras, their smart TV software platforms are often .
From Amazon and Roku to Samsung, LG and Vizio, all major smart platforms and TVs are capturing your viewing data. Software and hardware makers use it to "improve" the products they offer, for example by tailoring show recommendations and the ads they show you. While potentially frustrating, the ability to show ads helps in keeping costs down when buying a new TV or streaming stick.
One tool for tracking is called Automatic Content Recognition, which is software that recognizes the images on your TV. ACR works regardless of whether the images come through an app or an HDMI port like a cable box, Xbox or PlayStation. The good news is that you can turn it off.
To find out how, we checked out all of the major TV makers' 2019 smart TV systems as well as dedicated streamers from Amazon, Roku and Nvidia (which uses Google). Here's what we found and what you can do about it. Just click the link below to jump to your device.

What TV makes it easiest to control your privacy? Roku
Of all of the TVs and streamers we looked at, Roku makes it easiest to opt out of viewing data collection. The menus use plain English to explain their terms of service and the privacy controls are easy to find: There's a dedicated "Privacy" section in the Settings menu that consists of three simple boxes.
The worst operator in our tests was Vizio. Its privacy controls were so complicated that in our initial hunt for the setting we had to reset our TV to factory settings to make sure that the right things were unchecked.
Those two represent the extremes among the systems we tested. Below you'll find them all along with step-by-step instructions for taking control of your data.
Amazon Fire TV
Amazon says it uses data to help operate devices, improve them and troubleshoot problems as well as "assess customer engagement, identify potential quality issues, analyze our business, and customize marketing offers" including ads. The exact data it captures varies by apps and services.
Here's how you can take back control. All settings can be found by going to Settings, then Preferences then Privacy Settings.
- Choose Device Usage Data and turn this setting off.
- Go to App Usage Data and turn this setting off.
- Select Internet-based Ads and turn this setting off.
- On some Fire TV television sets Amazon will also capture data from what you're watching with an antenna. For those TVs, find Over-the-air data and turn it off.
Google Android TV
The data collected includes terms you search for, videos you watch, views and interactions with content and ads, voice and audio information when you use audio features, purchase activity, people with whom you communicate or share content, activity on third-party sites and apps that use our services.
Google says thatas a platform does not perform ACR or monitor what specific content users are watching.
Here's how to control data on an Android TV device like thewe tested.
- Head to Settings, scroll down to a section labeled Personal, click Usage and diagnostics and make sure that tab is switched to off.
- To manage other data Google has on you, such as YouTube and search histories and web and activity data, head to myactivity.google.com.
Roku says that while it shares some data with advertisers, but it does "not share your viewing data with them."
Here's what you need to do to limit or disable some of the tracking.
- From the main Roku menu, open Settings and head to Privacy.
- For Advertising, make sure that the box Limit ad tracking is checked.
- To disable ACR, scroll to the tab labeled Smart TV experience and make sure both options there are unchecked.
This will limit what data Roku collects and disable ACR, though it means that Roku won't be able to make the same recommendations for content.
LG smart TVs (web OS)
LG is the only manufacturer we contacted that didn't respond to our questions, so we can't confirm what data its system collects. Regardless, here's how to limit it.
- In the main Settings menu select General.
- To turn off content recommendations, head to AI Service and uncheck AI Recommendation, which will stop LG from tracking this usage data.
- Here you can withdraw your agreement from Interest-Based Advertisement, Viewing Information, Live Plus, which is what LG uses to capture viewing habits with ACR, as well as LG Channels.
- Going into Additional Settings from that General menu will allow you to also turn off Cookies, which tracks which web ads have appeared on your TV and makes sure the same ads don't "show up continuously above a certain level."
Samsung Smart TVs (Tizen)
Samsung Smart TVs use ACR when providing recommendations on what to watch or to give more relevant ads. In addition to ACR, the company will also collect status information about the TV when diagnosing problems or to improve products.
Opting out of what is known as Viewing Information Services should disable the ACR capture. Here's how you can do that.
- Open Settings, select Support and head to Terms & Policy.
- Choose Viewing Information Services and uncheck the I agree to turn off ACR.
- Head to Interest-Based Advertisements Service Privacy Notice and uncheck Enable to make the content and advertising on Smart TV more interactive to turn off personalized ads.
Note that for services like voice control through Bixby, you will need to agree to Samsung's Voice Recognition Service Privacy Notice.
Sony smart TVs (Android TV)
We used a Sony Bravia Android TV in our test, but the experience should be comparable to other Android TV devices.
- Head to Settings and scroll down to a tab labeled Initial setup.
- Unchecking them all and clicking proceed should stop them from collecting your information.
Vizio smart TVs (SmartCast)
Vizio says that the viewing data it collects is "device-level information about what's playing on a Vizio Smart TV, such as the shows, movies, networks, and ads" and that the data is "never linked with identifying information like names and contact information."
The company says that the data it collects is "licensed to media companies, advertisers and measurement companies." Unfortunately, Vizio makes it really hard to check or opt out of this tracking on its recent SmartCast TVs. Here's how.
- Go into Settings by tapping Menu on the remote.
- Choose System followed by Reset & Admin.
- Head down to Viewing Data (or "Smart Interactivity" on older models) and make sure that toggle is set to Off. This will disable ACR collection and stop Vizio from sharing what you're doing with third parties.
Unfortunately, Vizio says that even if Viewing Data is disabled it will still collect information when "consumers use SmartCast Home" on new models. SmartCast Home is Vizio's platform for streaming apps.
"Activity Data includes device-level information and clicks and impressions, which are collected in order to support and maintain the SmartCast experience as well as continuously improve and add value to Vizio products, including creating new services, or providing recommendations," the company told CNET, adding that the data collected here "is not licensed to third parties."
