To disable a smart TV’s “snooping” feature, turn off its Automatic Content Recognition (ACR) or viewing-data setting in the TV’s privacy menu. The exact name and path depend on the manufacturer, operating system, model, software version, and region. An ACR opt-out applies to that specific viewing-recognition feature; it does not necessarily stop app, account, device-usage, advertising, or voice-related data collection.
What the TV’s “snooping” setting does
On many smart TVs, the feature people call snooping is Automatic Content Recognition (ACR), or a related viewing-data service. It can identify content shown on the TV and send viewing information to the platform. For example, Roku says Smart TV Experience can collect what and when a viewer watches through antenna TV and devices connected to the television. Vizio describes Viewing Data as information about programming, advertisements, connected devices, and third-party apps.
ACR may cover more than the TV’s built-in channels. In a 2024 peer-reviewed study, researchers measured ACR activity on Samsung and LG TVs while the sets were used with external HDMI sources. LG says its ACR can operate with supported Live TV, HDMI-connected devices, and LG Channels, but not inside third-party streaming apps available through LG Apps. Those findings and descriptions concern the studied conditions and LG’s system; they should not be assumed to describe every TV.
Find the setting for your TV
First identify the TV’s manufacturer, operating system, model year, and region. Then look under Settings for Privacy, Terms, or Viewing Information. Common labels include ACR, Viewing Data, Viewing Information Services, Live Plus, and Smart TV Experience, but those names are not interchangeable controls guaranteed to appear on every set. If a path does not match your screen, consult the manufacturer’s current support instructions for your exact model and software version. The Network Advertising Initiative notes that settings can differ between device or software versions.

| TV platform | Documented setting or path | What the source says it covers |
|---|---|---|
| Roku TV | Settings > Privacy > Smart TV Experience | Roku says the feature can collect what and when you watch through antenna TV and devices connected to the TV. |
| Vizio OS / SmartCast | All Settings > Privacy & Legal > Viewing Data. On an older menu: All Settings > Admin & Privacy > Viewing Data. | Vizio distinguishes Viewing Data from separate Activity Data collection. |
| Fire TV televisions | Settings > Preferences > Privacy Settings | Amazon lists separate controls for Device Usage Data, Collect App Usage Data, Interest-based Ads, and over-the-air viewing data on supported smart TVs. |
| LG TVs | Turn off ACR in TV settings; the exact route depends on model and software. | LG says users can withdraw from optional agreements and turn off ACR. Check LG’s current support instructions for the specific model. |
Roku documents its path for the U.S. Vizio publishes both current and older menu paths, which may not match every model. Amazon’s controls are distinct categories, not one universal ACR switch for all Fire TV products. For Samsung, Google TV, and Sony, do not rely on a menu path for a different model or software version; verify the route with the manufacturer’s support documentation.
Turn off the relevant control
- Open the TV’s settings. Use the remote’s Settings button or the on-screen Settings menu.
- Open the privacy or viewing-data area. Look for the platform-specific label in the table above, or search the menu for “ACR,” “Viewing Data,” “Viewing Information,” or “Smart TV Experience.”
- Switch off the viewing-recognition control. If the TV presents an agreement or confirmation, review it and confirm the opt-out.
- Review other privacy controls separately. On Fire TV televisions, for example, device usage, app usage, interest-based advertising, and over-the-air viewing data have separate settings.
- Check the menu again after an update or reset. Menu labels and available controls can change with software versions; confirm the setting is still off on your TV.
What the opt-out does—and does not—change
Turning off ACR limits or stops the specific viewing-recognition processing described by that platform, subject to the TV’s terms and configuration. It is not proof that the TV or its apps send no other information.

It also says tailored advertising on other devices may continue for a period based on previously shared data. This described deletion behavior is specific to Vizio and should not be generalized to other brands.
Check the TV’s privacy menu, relevant account settings, and the privacy controls inside streaming apps if you want to review data practices beyond ACR.

Does turning off ACR mean the TV records the room?
Not necessarily. ACR is a content-recognition function, and its implementation varies. LG says its system uses audio fingerprinting and does not collect or store voice recordings, other audio recordings, screenshots, screen images, or video recordings. That statement describes LG’s system; it is not a guarantee about every manufacturer or every feature on a TV. Review the privacy explanation for your own model and distinguish ACR from voice assistants, microphones, and other services.

Why the exact model and version matter
Manufacturers can change menu names, routes, and available controls across model years, software updates, and regions. The 2024 study of Samsung and LG TVs found that, in its experiments, ACR operated when the sets were used as external displays and that opting out stopped observed traffic to ACR servers. It examined two platforms under particular device and software conditions, so it does not establish how every model, market, or later firmware behaves.
For a practical check, verify the setting on the TV itself after making the change. If your menu differs, use the manufacturer’s support page for the exact model and software version rather than applying another platform’s instructions.
