How Smart TVs Collect Your Data
Smart TVs have evolved well beyond simple display devices. By 2026, virtually every television sold includes an internet-connected operating system, built-in microphones, cameras, and sophisticated data-collection capabilities. Understanding what data is being gathered is the first step toward protecting yourself.
The primary collection method used by most manufacturers is Automatic Content Recognition, commonly known as ACR. This technology captures samples of everything displayed on your screen — including content from streaming apps, cable boxes, game consoles, and Blu-ray players — and matches those samples against a database to identify exactly what you are watching. This viewing data is then sold to advertisers and data brokers. ACR operates silently by default on most platforms, including Roku TV, LG webOS, Samsung Tizen, and Android TV/Google TV devices.
Beyond ACR, smart TVs collect app usage patterns, voice command recordings, device identifiers, IP address information, and household demographic inferences. Many platforms also embed trackers inside their app ecosystems that report back to third-party advertising networks.
Disabling ACR and Limiting Tracking
The most impactful action you can take is disabling ACR on your device. The setting name varies by manufacturer:
- Samsung: Navigate to Settings → Support → Terms & Privacy → Viewing Information Services and toggle it off. Also check Privacy Choices under the same menu.
- LG: Go to Settings → All Settings → General → About This TV → User Agreements, and opt out of Live Plus and interest-based advertising.
- Roku (and Roku TV): Go to Settings → Privacy → Smart TV Experience and uncheck the relevant options. Also disable ad personalization under Advertising.
- Google TV / Android TV: Access Settings → Privacy → Ads and opt out of ads personalization. Google's additional data sharing options are found under Account settings.
Even after disabling these features, revisit these menus periodically. Firmware updates have been known to reset privacy settings to their defaults, a practice that has drawn regulatory attention in several jurisdictions.
Network-Level Protections
Controlling your smart TV at the network level adds a meaningful second layer of protection. The most effective approaches include:
Router-based DNS filtering: Services that block known advertising and tracking domains at the DNS level will prevent your TV from reaching those servers regardless of its software settings. A Pi-hole or comparable DNS sinkhole installed on your home network can block ACR and telemetry endpoints automatically.
Network segmentation: Placing your smart TV on a separate VLAN or a dedicated guest Wi-Fi network isolates it from your computers, phones, and other sensitive devices. Even if the TV is compromised or excessively talkative, it cannot interact with other devices on your primary network.
VPN at the router level: Routing your smart TV's traffic through a VPN at the router prevents your Internet Service Provider from observing your viewing habits and masks your household IP address from the platforms you connect to. Note that a VPN alone does not stop ACR, which operates within the TV's own software stack.
Managing Microphones and Cameras
Many smart TVs include always-on voice activation features. Unless you actively use voice controls, disabling the microphone in your TV's settings is advisable. On models with physical camera modules, a simple opaque cover provides a reliable hardware-level safeguard that no software update can override.
Review which apps have been granted microphone access on your TV's operating system, and revoke permissions for any app that does not require them for its core function.
App and Account Hygiene
Limit the number of apps installed on your smart TV to only those you actively use. Each additional app represents a potential additional data source. Where possible, avoid signing into streaming services directly on the TV using your primary account credentials. Consider using your TV primarily as a dumb display by connecting a dedicated streaming device that you have already hardened, or by casting content from a secured phone or laptop.
Review the privacy policies of your TV manufacturer and the streaming platforms you use. In many regions, including the EU under GDPR and several US states under evolving consumer privacy laws, you have the right to request deletion of data the company holds about you.
Keeping Firmware Updated — Carefully
Security patches delivered through firmware updates protect against known vulnerabilities, so keeping your TV updated is generally advisable. However, always check user reports after a major update, as version changes occasionally introduce new data-sharing features enabled by default. Review your privacy settings immediately after any firmware update.
