Smart TV Privacy UK 2026: What Your Television Knows About You and How to Stay Safe

Your smart TV is one of the most data-hungry devices in your home — and most people have no idea just how much information it collects. From automatic content recognition (ACR) that tracks every programme, film, and advert you watch, to built-in microphones that listen for voice commands, modern smart TVs from Samsung, LG, Sony, Hisense, and TCL are sophisticated data-collection platforms as much as they are entertainment devices. This thoroughly researched guide explains exactly what your smart TV knows about you, which UK data protection rights apply, and the practical steps you can take to protect your privacy in 2026.

This guide covers smart TVs running Tizen OS (Samsung), webOS (LG), Google TV (Sony, TCL, Hisense), and Amazon Fire TV (Amazon, some Hisense models), all of which are widely available in the UK market as of September 2026.

What Data Does Your Smart TV Collect?

Automatic Content Recognition (ACR)

ACR is the most significant privacy concern with modern smart TVs, and it is enabled by default on most sets sold in the UK. ACR technology works by capturing samples of what is displayed on your screen — whether from a streaming app, a Blu-ray player, a games console, or a traditional broadcast — and matching those samples against a database to identify exactly what you are watching. This data is then used to build a detailed viewing profile that can be shared with advertisers and third-party data brokers.

Samsung calls its ACR system "Samsung TV Plus" and "Viewing Information Services." LG refers to its implementation as "Live Plus." Sony's Google TV platform uses Google's own data collection systems. Hisense and TCL sets running Google TV similarly use Google's ACR infrastructure. Amazon Fire TV uses its own ACR system tied to Amazon's advertising platform.

Under the UK GDPR (retained in UK law following Brexit as the UK GDPR), ACR data collection requires your informed consent. However, many manufacturers bury the consent mechanism deep within setup menus or present it in a way that makes opting out non-obvious. The Information Commissioner's Office (ICO) has published guidance on smart TV data collection and the obligations manufacturers have under UK GDPR.

Voice Data and Always-On Microphones

Most smart TVs sold in the UK include built-in microphones for voice control. Samsung TVs use Bixby and support Amazon Alexa and Google Assistant. LG TVs use ThinQ AI with Google Assistant support. Sony Google TV sets use Google Assistant natively. Amazon Fire TV sets use Alexa.

Voice assistants on smart TVs typically operate in a "wake word" mode, meaning the microphone is always listening for a trigger phrase (such as "Hey Google" or "Alexa"). While manufacturers state that audio is only processed and transmitted after the wake word is detected, the microphone must remain active to detect that wake word. If you are concerned about this, most smart TVs include a physical microphone mute button or switch — check your TV's remote control or settings menu.

Under UK GDPR, voice data processed by smart TV assistants is subject to data protection obligations. Samsung, LG, Sony, and Amazon all publish privacy policies that describe how voice data is handled, stored, and deleted. These policies are accessible via each manufacturer's UK website.

App Usage and Streaming Data

Smart TV operating systems track which apps you open, how long you use them, and in some cases, what content you access within those apps. This data is used to personalise recommendations and, in many cases, to serve targeted advertising. Netflix, Disney+, Amazon Prime Video, and other streaming services also collect their own viewing data independently of the TV's operating system.

Network and Device Data

Smart TVs collect technical data including your IP address, MAC address, Wi-Fi network name (SSID), and device identifiers. This data is used for analytics, software updates, and in some cases, advertising targeting. Your IP address can be used to infer your approximate location, even if you have not granted the TV explicit location permissions.

UK Data Protection Rights and Smart TVs

UK residents have significant rights under the UK GDPR and the Data Protection Act 2018 when it comes to smart TV data collection. These rights include:

• Right to be informed: Manufacturers must tell you what data they collect and why, in clear and plain language.
• Right of access: You can request a copy of all personal data a manufacturer holds about you (a Subject Access Request, or SAR).
• Right to erasure: You can request that your data be deleted, subject to certain conditions.
• Right to object: You can object to your data being used for direct marketing or profiling.
• Right to withdraw consent: Where data collection is based on consent, you can withdraw that consent at any time.

The Information Commissioner's Office (ICO) is the UK's data protection regulator. If you believe a smart TV manufacturer has breached your data protection rights, you can report this to the ICO via its website. The ICO has the power to investigate and fine organisations that breach UK GDPR.

How to Disable ACR on Your Smart TV

Samsung Tizen OS (2026 Models)

On Samsung smart TVs running Tizen OS, ACR is controlled through the "Viewing Information Services" setting. To disable it:

1. Press the Home button on your remote and navigate to Settings.
2. Select Support, then Terms & Policies.
3. Find "Viewing Information Services" and toggle it off.
4. Also check "Interest-Based Advertising" under the same menu and disable it.

Samsung also offers a "Do Not Sell My Personal Information" option in the same menu, which is relevant for UK users exercising their right to object under UK GDPR.

LG webOS (2026 Models)

On LG smart TVs running webOS, ACR is called "Live Plus." To disable it:

1. Press the Settings button (gear icon) on your remote.
2. Navigate to All Settings, then General, then Additional Settings.
3. Find "Live Plus" and toggle it off.
4. Also navigate to All Settings, then General, then About This TV, then User Agreements, and review and opt out of data collection agreements.

Sony Google TV

Sony TVs running Google TV use Google's data collection infrastructure. To limit data collection:

1. Press the Settings button and navigate to Privacy.
2. Under "Usage & Diagnostics," toggle off data sharing.
3. Navigate to Google, then Ads, and opt out of personalised advertising.
4. Under "Samba Interactive TV" (if present), disable this service, which provides ACR functionality.

Amazon Fire TV

On Amazon Fire TV sets (including some Hisense models with Fire TV built in):

1. Navigate to Settings, then Preferences, then Privacy Settings.
2. Disable "Collect App and Over-the-Air Usage Data."
3. Disable "Interest-Based Ads."
4. Navigate to Settings, then My Fire TV, then About, then Legal Notices, then Privacy Settings to review additional options.

Hisense and TCL (Google TV Models)

Hisense and TCL models running Google TV follow the same Google TV privacy settings as Sony. Additionally, check for "Samba Interactive TV" or similar ACR services in the app list and disable or uninstall them where possible.

How to Disable Voice Listening

To minimise voice data collection on your smart TV:

• Samsung: Navigate to Settings, then General, then Voice, and disable "Voice Wake-up." You can also use the microphone mute button on the Samsung remote (the button with a microphone icon with a line through it).
• LG: Navigate to Settings, then General, then AI Service, then Voice Recognition Settings, and disable "Use Voice Recognition." The LG Magic Remote also has a microphone button — press and hold to use voice, rather than always-on listening.
• Sony Google TV: Navigate to Settings, then Privacy, then Google Assistant, and review and restrict permissions. You can also disable "Hey Google" detection in the Assistant settings.
• Amazon Fire TV: Navigate to Settings, then Alexa, and disable "Hands-Free Alexa" to prevent always-on listening. You can still use Alexa by pressing the microphone button on the remote.

Network-Level Privacy Protection

Beyond the TV's own settings, you can take additional steps at the network level to limit smart TV data collection:

Use a Pi-hole or DNS-Based Ad Blocker

A Pi-hole is a network-wide DNS-based ad blocker that can block known tracking and advertising domains at the router level, preventing your smart TV from communicating with data brokers even if ACR is enabled. Pi-hole is free, open-source software that runs on a Raspberry Pi (available from Amazon UK, Pimoroni, and The Pi Hut). Setting up a Pi-hole requires some technical knowledge but is well within reach for most home users.

Segment Your Smart TV onto a Separate Network

Many modern routers — including those from BT, Sky, Virgin Media, and third-party options like TP-Link Deco and Eero — support guest networks or VLAN segmentation. Placing your smart TV on a separate network segment prevents it from communicating with other devices on your home network (such as your laptop or NAS drive) while still allowing it to access the internet for streaming.

Consider a Streaming Stick Instead

One approach favoured by privacy-conscious users is to purchase a "dumb" TV (a display without a smart OS) or to disable the smart TV's internet connection entirely, and instead use a dedicated streaming device such as an Apple TV 4K (available from Apple UK, Amazon UK, and Currys, priced from around £149 as of September 2026) or a Chromecast with Google TV (available from Amazon UK and Currys, priced from around £49 as of September 2026). This approach gives you more control over which platform's data practices you are subject to, and allows you to replace the streaming device more easily than the TV itself.

What About Smart TV Cameras?

Some premium smart TVs include built-in cameras for video calling and gesture control. Samsung's 2026 lineup includes models with a pop-up or clip-on camera accessory. LG's premium OLED models have offered camera accessories in recent years. If your TV has a camera, check whether it has a physical privacy shutter or cover — if not, consider covering it with opaque tape when not in use. Review the camera's permissions in your TV's settings to ensure it is only active when you explicitly enable it.

Practical Privacy Checklist for UK Smart TV Owners

• Disable ACR / Viewing Information Services during initial setup or in the settings menu
• Opt out of interest-based advertising in your TV's privacy settings
• Disable "Hey [Assistant]" always-on voice detection if you do not use it regularly
• Review and decline unnecessary data-sharing agreements in your TV's Terms & Policies menu
• Consider placing your smart TV on a guest network or separate VLAN
• Use a Pi-hole or DNS-based blocker to block known tracking domains at the network level
• Submit a Subject Access Request to your TV manufacturer if you want to know what data they hold about you
• Check for firmware updates regularly — manufacturers sometimes add new privacy controls in software updates
• If you have a smart TV camera, cover it when not in use or disable it in settings

The Bottom Line

Smart TVs are powerful entertainment devices, but they are also sophisticated data-collection platforms. The good news for UK consumers is that UK GDPR gives you meaningful rights over your data, and every major smart TV manufacturer operating in the UK is legally required to provide opt-out mechanisms and respond to Subject Access Requests. The steps outlined in this guide — disabling ACR, limiting voice data collection, and using network-level protections — can significantly reduce the amount of data your TV collects without meaningfully affecting your viewing experience.

The most important step is to take action during initial setup, before your TV has had the chance to build a viewing profile. If you have already set up your TV without adjusting these settings, it is not too late — the privacy controls described above are available in the settings menus of all major smart TV platforms available in the UK as of September 2026. Prices and product availability are subject to change; always verify current details with the relevant manufacturer or retailer.
