A new TV in an Australian lounge room usually gets set up in a hurry: Wi-Fi password, ABC iview, SBS On Demand, Netflix, Kayo or Stan, then straight into whatever everyone was waiting to watch. The privacy screens appear during that rush, often as a stack of “agree” buttons before the remote batteries have settled in.

You do not need to treat a Smart TV like a spy device to make better choices. The useful approach is simpler: turn off the tracking that does not improve your viewing, keep the security bits that do, and accept that some data sharing is part of using streaming apps, recommendations and voice search.

Start with ACR, because it is the least obvious setting

Automatic content recognition, usually called ACR, is the setting most worth checking on day one. It can identify what is playing on the screen by matching snippets, signals or patterns against a database. Depending on the brand and model, that may include free-to-air broadcasts, HDMI inputs, streaming video, or only certain viewing modes.

The point of ACR is usually personalised recommendations, measurement, interactive features and advertising. It is not the same as someone watching your screen live, but it can still create a useful profile of what is watched on that TV. In a shared household, that profile may mix kids’ cartoons, live sport, news, YouTube and late-night streaming into one device-level picture.

Look for settings with names such as Viewing Information Services, Live Plus, Automatic Content Recognition, Smart TV viewing data, interest-based advertising or viewing data. The exact path varies, but it is usually under Settings, then Privacy, Terms, Support, System or Additional Settings.

  • Samsung TVs: look for privacy terms related to Viewing Information Services, Smart Hub, customisation or advertising.
  • LG TVs: look for Live Plus and advertising or home promotion settings.
  • Google TV and Android TV: check Privacy, Ads, usage and diagnostics, app permissions and recommendation settings.
  • Hisense, TCL and other brands: look for Automatic Content Recognition, advertising ID, enhanced viewing, usage data or VIDAA/Google TV privacy controls depending on the platform.

Trade-off: turning ACR off may make recommendations less relevant and may disable some “enhanced” TV features. For most people, that is a fair swap. Your streaming apps will still work. Free-to-air channels will still work. HDMI devices such as consoles and set-top boxes will still work.

Reset or delete the advertising ID

Many Smart TVs and TV platforms have an advertising ID: a device-level identifier used by apps and ad systems to recognise the TV without necessarily using your name. It is similar in spirit to the ad ID on a phone. Resetting it gives the TV a fresh identifier. Deleting it, where offered, is stronger because apps cannot rely on that same ID for ad personalisation.

On Google TV, the relevant path is typically Settings, Privacy, then Ads. Some TVs offer Reset advertising ID, Delete advertising ID, or a toggle for personalised ads. Other platforms use slightly different wording.

Trade-off: this does not remove ads. It changes how easily ads can be personalised or linked to a persistent TV identifier. You may still see ads based on the app you are using, the content category, your rough location, or account-level settings inside a streaming service.

Turn off personalised recommendations if they are not useful

Smart TV home screens are increasingly built around recommendations: rows of shows, promoted apps, “continue watching” rails and suggested rentals. Some are genuinely convenient. Some are mostly advertising dressed as discovery.

Check for settings called personalisation, customisation service, recommendations, content preferences, home screen channels or watch activity. If the TV lets you disable personal recommendations while keeping basic app shortcuts, that is usually a good privacy setting to change.

Trade-off: the home screen may become less clever. That is not always a loss. A cleaner app launcher can be better than a home screen that constantly guesses what the household might watch next.

Stop auto-play previews where possible

Auto-play is not only annoying; it can quietly disclose viewing habits in a shared room. A TV that starts loud previews while someone browses can reveal genres, titles or account profiles to everyone nearby. It can also chew through data on slower or capped internet plans, although most Australian fixed-line plans are less sensitive to this than mobile broadband.

There are two places to check. First, look in the TV’s own home screen settings for auto-play previews, video previews, featured content or home promotions. Second, open individual apps and check their playback settings. Netflix, YouTube, Prime Video and other services often control their own previews separately from the TV operating system.

Trade-off: you lose motion previews and sometimes quick trailers. In return, the TV feels calmer and reveals less while browsing.

Be deliberate with voice controls

Voice search can be useful, especially with a clumsy TV keyboard. The privacy question is whether you want always-listening wake words, cloud voice processing, microphone permissions and voice history attached to the TV or account.

If your remote has a microphone button that only listens while pressed, that is a reasonable middle ground for many households. If the TV itself has hands-free voice control, check whether the wake word can be disabled. Also check app permissions for microphone access, particularly on Google TV or Android TV models.

Trade-off: disabling voice features means slower searching and less hands-free control. Keeping push-to-talk on the remote while disabling always-on listening is often the practical compromise.

Do not sign in to everything just because the TV asks

During setup, TVs often nudge you to create or sign in to a manufacturer account. Some features may need it: app downloads, device syncing, warranty tools, voice assistants, cloud photo screensavers or personalised recommendations. Basic HDMI use and many streaming apps may not.

Use a separate TV profile or household email where that makes sense, especially for a share house, rental property, Airbnb-style room, or family TV used by guests. Avoid signing a child’s personal account into the main TV profile unless you actually need that integration.

Trade-off: skipping the manufacturer account may reduce convenience and app-store access on some models. If the TV becomes awkward without it, sign in, then revisit privacy, ads and data-sharing settings afterwards.

Review app permissions before installing the usual apps

Streaming apps need internet access. Some may request location, microphone, storage or local network access. A weather app may reasonably ask for location. A screen-mirroring app may need local network access. A basic video app generally should not need the microphone unless it has voice search.

On Google TV and Android TV, use Settings, Apps, then permissions. On other platforms, look for app management or privacy permissions. Remove apps you will not use, especially preloaded games, shopping channels and promotional apps.

Trade-off: being too aggressive can break features such as casting, voice search, Bluetooth accessories or media playback from a USB drive. If something stops working, restore only the permission that feature clearly needs.

Keep diagnostics limited, but keep updates on

Usage diagnostics, crash reports and performance data are often optional. Turning off “send usage data” or “marketing diagnostics” is sensible if you do not want extra behavioural reporting.

Security updates are different. Leave automatic software updates on unless you have a specific reason to manage them manually. A Smart TV is another computer on your home network. Updates fix bugs, app compatibility problems and security issues. Privacy is not improved by leaving old firmware in place.

Trade-off: automatic updates can occasionally change menus or app behaviour. That annoyance is usually worth accepting for security and compatibility.

What a VPN can and cannot do on a Smart TV

A VPN may hide your home IP address from some services and route traffic through another location. That can be useful for privacy on untrusted networks, but a lounge-room TV on your home Wi-Fi is not the same situation as a laptop on airport Wi-Fi.

For streaming, be honest about the limits. Catalogues differ because of licensing. Services may restrict VPN use, detect it, or show different libraries depending on account country, payment method, device location and rights agreements. A VPN should not be treated as a guaranteed way to unlock overseas catalogues, and it does not override the terms of the services you use.

What it will not fix: a VPN does not stop a signed-in app from knowing what you watch inside that app. It does not remove the TV’s advertising ID. It does not disable ACR. It does not replace good account settings.

What is mostly wishful thinking

Some privacy tips sound neat but do less than people expect. A few are worth putting in perspective.

  • Changing DNS: custom DNS can block some tracking domains, but it can also break apps and will not stop data sent to the same domains used for normal streaming.
  • Using private browsing: TVs rarely work like desktop browsers, and most tracking happens through apps, device IDs and account activity rather than browser cookies alone.
  • Covering the camera: useful if your TV has a camera, but many modern TVs do not. It does nothing for viewing data, ad IDs or app tracking.
  • Never connecting the TV to the internet: effective for privacy, but only practical if you use an external streaming box, console or antenna and accept losing smart features.
  • Factory resetting every few months: this is disruptive and unnecessary for most homes. Review the settings instead.

A sensible day-one setup

The best Smart TV privacy setup is not extreme. It is a short pass through the settings before habits settle in. Do it once when the TV is new, then again after major software updates.

  • Turn off ACR, viewing data or enhanced viewing unless you genuinely value those features.
  • Reset or delete the advertising ID, and disable personalised ads where offered.
  • Switch off auto-play previews on the TV home screen and inside major streaming apps.
  • Use push-to-talk voice search rather than always-on listening if that suits your household.
  • Install only the apps you use, then review microphone, location and local network permissions.
  • Limit optional diagnostics and marketing data, but keep automatic security updates enabled.
  • Remember the boundary: privacy settings reduce unnecessary tracking; they do not make streaming apps anonymous.
