Smart TVs can make watching films, streaming programmes and accessing online services easier, but they can also collect information about what people watch.
Some manufacturers use Automatic Content Recognition (ACR) technology to identify content displayed on television screens, potentially turning viewing habits into data for audience measurement and targeted advertising.
Although this feature can help improve recommendations and advertising, not everyone wants their television monitoring their viewing activity.
The good news is that most major smart TV platforms offer privacy settings that let users manage certain types of data collection.
Here's how to turn off smart TV tracking, review advertising preferences and limit the information your television shares.
What Is Automatic Content Recognition on Smart TVs?
Automatic Content Recognition is a technology that identifies content displayed on a television using audio or visual signals.
Depending on the manufacturer, it can recognise programmes watched through built-in streaming applications, connected devices, cable boxes and other sources.
Manufacturers may use this information to understand viewing habits, measure audiences and deliver personalised advertisements, although advertising use and consent requirements vary.
However, ACR is not the only way smart TVs collect information. Connected applications, voice assistants and advertising services may also gather data under separate privacy agreements.
This means disabling one tracking feature does not necessarily stop every form of data collection.
How To Turn Off Smart TV Tracking
The exact instructions depend on your television's manufacturer, operating system and software version. However, these are the main settings worth checking.
1. Review your television's privacy settings
Open your television's main settings menu and look for sections labelled 'Privacy', 'Terms and Privacy', 'User Agreements' or 'Privacy Choices'.
Check whether you have agreed to optional viewing-information collection, personalised recommendations or advertising services. Withdraw consent for features you do not want to use.
2. Disable Automatic Content Recognition
Look for settings associated with ACR or viewing-information services.
These may have different names depending on the manufacturer:
- Samsung: Look for 'Viewing Information Services' in the TV's privacy or terms and privacy settings. The exact menu path varies by model and software version.
- LG: Review the 'Viewing Information Agreement' and look for ACR or 'Live Plus' settings, depending on your model and webOS version.
- Roku: Go to Settings, select Privacy, then Smart TV Experience and look for the option to use information from TV inputs. The wording and available controls may vary.
Other brands may use terms such as 'Viewing Data', 'Interactive Services' or 'Smart TV Experience'.
Switch off the relevant feature where available.
3. Turn off personalised advertising
Look for options labelled 'Interest-Based Advertising', 'Personalised Ads' or 'Advertising Preferences'.
Disabling these features can limit how certain information and advertising identifiers are used to personalise adverts. However, this may not stop ACR or other forms of viewing-data collection, so check those settings separately.
Some televisions also offer an option to reset their advertising ID or limit ad tracking.
4. Review voice assistant permissions
If you rarely use voice commands, check whether your television allows you to disable voice recognition or microphone-related features.
Also review any separate permissions granted to built-in voice assistants and connected applications.
Menu names and available controls vary, so consult your manufacturer's support documentation if you cannot locate a particular setting.
Does Turning Off Smart TV Tracking Actually Work?
Disabling ACR is a useful privacy measure, but it does not guarantee that a television will stop communicating with its manufacturer's servers.
A Northeastern University study published in October 2026, titled Watching the Watchers: Privacy Analysis of U.S. Smart TV Automatic Content Recognition, examined 12 televisions from 10 manufacturers across eight operating systems through 5,943 controlled experiments.
The researchers said the tested operating systems accounted for approximately 95% of the US smart TV market, although the findings may not apply to every model, software version or region.
The study found that ACR-related network traffic continued after users opted out on some tested Samsung and Vizio televisions.
On Samsung TVs running Tizen, researchers detected traffic consistent with ACR in 41 of 60 antenna-viewing tests and 18 of 30 HDMI tests. Vizio televisions running SmartCast continued contacting the identified ACR endpoint in all tested runs.
Results for Roku devices varied. The opt-out worked for antenna viewing on the Roku TV tested, but did not cover Roku's own streaming service.
However, most ACR-related traffic was encrypted, preventing researchers from directly reading its contents or confirming what information companies retained on their servers.
The team identified traffic patterns consistent with ACR continuing after opt-outs, but this did not establish that every transmission contained identifiable viewing information or was used for advertising. VIDAA OS was an exception because researchers could inspect some unencrypted viewing data.
The findings highlight why consumers should understand what individual privacy settings actually control rather than assuming one opt-out disables every form of data collection.
Roku also explains that disabling ACR does not prevent all information collection through its platform and streaming services. Previously collected information may also be retained after users opt out.
Other Ways To Protect Your Smart TV Privacy
If you want to limit the information your television shares, consider these additional precautions:
- Disconnect it from the internet: This prevents online data transmission through that connection, but also disables internet-dependent features such as streaming applications. The TV may still process information locally.
- Review app permissions: Netflix, YouTube and other applications have their own privacy policies and data collection practices.
- Use an external streaming device: A separate streaming device can reduce reliance on your television's built-in smart platform, but it is not a guaranteed way to avoid tracking. Some TVs can recognise content displayed through HDMI inputs, while the streaming device itself may also collect viewing data.
- Recheck privacy settings after updates: Firmware updates, factory resets and changes to user agreements may affect your television's privacy preferences. Review your settings periodically rather than assuming previous choices remain unchanged.
- Consider a separate Wi-Fi network: A guest network can help isolate your television from other connected devices in your home, although it will not prevent online tracking.
Disabling ACR also does not necessarily delete information already collected. Check your manufacturer's privacy policy or account settings if you want to request access to or deletion of previously collected data.
Take Control of Your Smart TV Privacy
Smart TVs do not need to become a privacy concern simply because they connect to the internet.
Reviewing optional tracking features, disabling personalised advertising and checking application permissions can help consumers make more informed decisions about their viewing data.
The important thing is to remember that switching off one tracking option does not necessarily disable everything.
Check your television's privacy settings regularly and understand what information each agreement allows the manufacturer and its partners to collect.
