In short and in plain language
A new TV asks many questions when you first turn it on. It asks about ads, about data and about the microphone. Your answers decide what the TV sends later.
You may say no to many of these questions. The TV still shows all channels. Look for the button to decline. Do not press Accept all right away.
Say yes to updates. An update closes gaps in the TV. Set updates to run on their own.
Delete apps you do not use. You can turn off the red button if you do not need it. You can also take back a yes later.
Black Friday is coming up at the end of November, and for many households the sales week is the occasion for a new TV. Flat-screen TVs remain the largest item in the consumer electronics market this year, with expected sales of 2.81 billion euros (Bitkom). Anyone unpacking a new set ends up in the initial setup first: language, Wi-Fi, channel scan and, in between, a series of consent prompts for content recognition, advertising, usage data and the microphone. What you select there determines which data the TV sends later. This article shows which prompts typically appear, what lies behind them, which ones you may decline, why automatic updates should still be switched on and how to sort out apps, accounts and your home network.
Key takeaways
- 67 percent of households in Germany had a smart TV in 2024 (Destatis). Which data the device sends later is largely decided during the initial setup right after unpacking.
- In an experiment by the Federal Cartel Office, only a quarter of the 20 test subjects found all privacy-related settings of the initial setup (Bundeskartellamt 2020). The highlighted “Accept all” button is rarely the privacy-friendly choice.
- Content recognition, advertising ID, usage data and the microphone are usually optional consents. Section 25(1) TDDDG generally requires consent for accessing information on the device, and it can be withdrawn at any time (Art. 7(3) GDPR).
- Automatic updates should be switched on, yet only just over a quarter of respondents, 26 percent, say they have enabled them (Cybersicherheitsmonitor 2026). Before buying, the product information sheet shows the updates promised (Regulation (EU) 2019/2021).
- Among people aged 65 and over, traditional TV is ahead of streaming at 94 percent versus 68 percent (Bitkom). If you mainly watch scheduled programs, switch off HbbTV when the red button goes unused and delete apps you do not need (BSI).
- A guest network separates the TV from computers and phones but can stop you from casting from your phone to the screen. After every major update, check the privacy and advertising settings again.
Why the initial setup decides about your data
The TV has long been a connected device: 67 percent of households in Germany had a smart TV in 2024 (Destatis). Streaming is widespread too, with 89 percent of Germans aged 16 and over watching videos, shows or movies over the internet (Bitkom). A smart TV has its own operating system, an app store, often a microphone in the remote and a permanent connection to the internet. This creates data that goes beyond the picture on the screen: device identifiers, installed apps, connected devices and, with add-on services such as voice assistants and recommendation services, usage and voice data as well (Bundeskartellamt 2020).
The Federal Cartel Office measured how hard these choices are in an experiment. In January and February 2019, 20 randomly selected employees of the authority were asked to set up a smart TV reset to factory settings so that as little data as possible went to the manufacturer and third parties, and to read all texts displayed along the way (Bundeskartellamt 2020). On average, the setup took one hour and 25 minutes. Even so, only a quarter of the test subjects discovered all privacy-related settings, and 35 percent did not achieve the privacy-friendly setup (Bundeskartellamt 2020). According to the authority, the group is not representative. The direction is still clear: anyone in a hurry in the living room, between the box and the remote, is likely to miss even more.
The Federal Cartel Office therefore gives buyers two pieces of advice that matter more during setup than any picture setting: smart TVs are often not set up to minimize data collection out of the box, and you should check whether the options highlighted on screen actually meet your needs (Bundeskartellamt 2020). The colored “Accept all” button is convenient but rarely the privacy-friendly choice. The inconspicuous route via “Customize”, “More options” or “Decline” takes a few extra clicks and saves you a search through nested menus later.
What the TV asks during setup
The names differ by manufacturer and operating system, but the prompts themselves are similar. They usually begin with terms of use and privacy notices that you must accept for the device to unlock its internet functions. Individual consents follow, which are usually optional. Some only appear later: consents, for example for a voice assistant, can also be requested only when the function is first used (Bundeskartellamt 2020). Six typical switches at a glance:
Content recognition
Identifies what is playing from picture or sound features, including from connected boxes and consoles. Used for recommendations and ads. Recommendation: off.
Advertising ID
An identifier that allows your behavior in different apps to be linked into a profile. Recommendation: personalized ads off, reset the identifier.
Usage data
Statistics, diagnostics and improvement programs. Not needed for picture and sound. Recommendation: off, allow program tips only if you want them.
Microphone
Voice commands from the remote are usually sent to a server for processing. Recommendation: off as long as you do not search by voice.
HbbTV
The red button opens broadcasters' on-demand libraries and extra information and sets up an internet connection to do so. Recommendation: off if you do not use it.
Automatic updates
Installs security updates without any action on your part. Recommendation: on. Where that is not possible, at least turn on notifications for new updates.
Content recognition: what the TV learns about your viewing
Automatic content recognition, often abbreviated ACR, compares content being played with a database based on its characteristics and thereby identifies shows and movies (Bundeskartellamt 2020). According to the authority's report, this makes it possible to track viewing behavior across TV channels and programs, all the way to connected set-top boxes and game consoles, and the data serves as a basis for targeted advertising (Bundeskartellamt 2020). Important for your decision: as far as can be seen, data from content recognition is always collected on the basis of a separate consent (Bundeskartellamt 2020). If you decline, you usually give up recommendations based on what you have watched, not television itself.
Advertising ID and personalized ads
Many devices assign an advertising identifier. According to the Federal Cartel Office report, the main purpose of such identifiers is to link data on user behavior from different applications and website visits into a comprehensive profile (Bundeskartellamt 2020). In the settings you will usually find two things: a switch for personalized or interest-based advertising and a button to reset the identifier. Switch off the first and use the second. You will still see ad tiles afterwards, but they should no longer be tailored to a profile of your viewing.
Usage data, diagnostics and recommendations
Under names such as usage information, diagnostic data or improvement program, the TV asks whether it may send information about your use to the manufacturer. In the investigation, the system-level software mainly collected device-related data, whereas add-on services such as voice assistants and recommendation services transmitted usage data on a considerable scale (Bundeskartellamt 2020). You need none of these switches for picture and sound. If you value personalized program tips, allow recommendations deliberately and decline the rest.
Microphone, camera and voice control
Many remotes have a built-in microphone. The BSI, Germany's Federal Office for Information Security, describes the path of a voice command: the remote records it, the TV forwards it over the internet to a server, and the server translates it into a command for the device (BSI). If you do not search by voice, switch voice control off. The BSI explicitly lists a built-in webcam, the microphone for voice control and remote access functions among the features that can be deactivated if they are not needed (BSI). If you want to use voice control deliberately, see the article voice assistants for seniors.
HbbTV: the red button with a return channel
HbbTV is the standard behind the red button: it lets you open broadcasters' on-demand libraries, additional information or current news (Bundeskartellamt 2020). Because the TV sets up an internet connection in addition to the broadcast signal, data can also flow back to the broadcasters or third parties; besides audience measurement, the Federal Cartel Office explicitly mentions profiling and targeted advertising (Bundeskartellamt 2020). The BSI advises deactivating or deleting services that are not needed, such as HbbTV and unused apps (BSI). The trade-off is personal: if you regularly catch up on shows via the red button, leave HbbTV on. If you do not use it, switch the function off.
Mandatory or optional: what you may decline
Legally, two rules stand behind many of these switches. Storing information on the device and accessing information already stored there are only permitted if you have consented on the basis of clear and comprehensive information (Section 25(1) TDDDG). Exempt is what is strictly necessary for a digital service you have explicitly requested to work (Section 25(2) TDDDG). For personal data processed on the basis of consent, the General Data Protection Regulation also applies: you can withdraw your consent at any time, and withdrawing must be as easy as giving it (Art. 7(3) GDPR).
In practice, this means: whatever the TV asks as a consent, you can usually decline without losing picture and sound. The Federal Cartel Office recommends making use of the option to refuse consents; if you really need them, they can still be given later (Bundeskartellamt 2020). The terms of use of the operating system are a different matter. In the authority's experiment, the initial setup could only be completed if the test subjects accepted the terms of use and privacy policy of the operating system provider (Bundeskartellamt 2020). Some devices offer to skip the smart functions entirely; the TV then remains a receiver for cable, satellite or antenna. For households that only watch scheduled programs, this can be a deliberate choice.
Declining is not a dead end
Updates: ask before buying, automatic afterwards
With updates, the recommendation is reversed: here, switching on is right. Software updates often close security gaps and should be installed promptly; the BSI considers automatic installation particularly advisable when it cannot be expected that someone will install updates manually on a regular basis (BSI). In everyday life this is not yet a matter of course: only just over a quarter of respondents aged 16 and over, 26 percent, say they have enabled automatic installation of updates (Cybersicherheitsmonitor 2026). Among users of smart home applications, 27 percent rarely install available software updates right away (Bitkom).
Devices that no longer receive security updates are a particular risk. If the device software is no longer maintained, the BSI suggests considering disconnecting the smart TV from the internet and the home network or uninstalling affected apps (BSI). The Federal Cartel Office names an external streaming device for the smart functions as a way out (Bundeskartellamt 2020); the article Streaming 2026 overview shows which sticks and boxes are available.
Before buying: check the product information sheet
How long a model receives updates is therefore part of the buying decision, especially with sale offers on previous-year models. When buying older models, active product support from the manufacturer may no longer be available at all or only for a short period (Bundeskartellamt 2020). For TVs as electronic displays, the EU requires the product information sheet to state the minimum availability of software and firmware updates (Regulation (EU) 2019/2021). You can reach the sheet via the QR code on the energy label. The same regulation requires the latest available security update to the firmware to remain available free of charge for at least eight years after the last unit of a model has been placed on the market (Regulation (EU) 2019/2021). This is not a promise that new updates will appear for eight years: what is regulated is that the most recent version remains available.
Sales law also helps. For goods with digital elements, the updates needed to keep the goods in conformity must be provided to you for the period you can expect given the type and purpose of the goods, and you must be informed about them (Section 475b(4) BGB, German Civil Code). If you do not install an update provided within a reasonable period, the seller is, under the conditions of Section 475b(5) BGB, not liable for a defect caused solely by the missing update. That is another reason to keep automatic updates switched on. The deadlines for withdrawal and warranty when buying devices are covered in the article gifting technology, and how to recognize reputable retailers during the sales week in the article spot fake shops.
Stricter rules are still to come. The EU Cyber Resilience Act requires manufacturers to provide a support period of at least five years unless the product is expected to be in use for a shorter time (Regulation (EU) 2024/2847). However, it largely only applies from December 11, 2027 (Regulation (EU) 2024/2847), and devices placed on the market before then are, as a rule, only subject to its requirements if they are substantially modified afterwards (Regulation (EU) 2024/2847). For a TV bought in the 2026 sales week, what counts above all is what the product information sheet and the manufacturer's statements say.
Apps, accounts and the home network
Every app is a piece of software with its own permissions. The BSI recommends downloading apps only from a trustworthy source, checking which access permissions they request before installing them and considering whether they are really needed in the long term; the more apps are installed on a smart TV, the higher the likelihood of being affected by security vulnerabilities (BSI). Many TVs come with preinstalled apps. Delete or deactivate what you do not use, as far as the device allows; the Federal Cartel Office calls every app a potential security risk, especially if it is no longer updated (Bundeskartellamt 2020).
The account deserves a brief thought. The operating system often requires an account with the provider for the app store. Give it its own strong password that you do not use anywhere else, and store it in a password manager. The BSI also advises allowing changes to settings and to the connection with the home network or cloud only for authorized persons, for example via a password or a PIN (BSI). A PIN for settings and app purchases also protects against children installing a paid app on the side. How to set up parental controls and screen time is explained in the article parental controls and screen time.
For the home network, there is one step that requires no new equipment: a guest network. Many routers can set up a second Wi-Fi network with its own name and password that is separated from the main network with your computer, phone and network storage. If the TV is connected there, a vulnerability in the device cannot reach your other devices as easily. The catch: casting from your phone to the TV then often fails because the guest network is separated from the main network. In that case, the TV stays on the main network, and updates, privacy-friendly settings and few apps carry the protection. How to secure your router and guest network is covered in the article secure your home router; on site, we take care of it as part of the router setup.
If you mainly watch traditional TV
Not everyone buys a smart TV for the apps. Among people aged 65 and over, traditional TV is still ahead of video streaming at 94 percent versus 68 percent (Bitkom). Across all age groups from 16 up, 81 percent watch current TV programs via cable, satellite or antenna at least now and then (Bitkom). If you mainly watch scheduled programs, you can decline generously during setup: content recognition, the advertising ID, usage data and the microphone then offer little benefit. Keep the on-demand apps you really use and delete the rest.
For parents or grandparents who find many prompts overwhelming, a simple home screen often helps more than any extra function: few tiles, favorite channels first, no preview videos that start automatically. If the TV is to run without internet at all, updates usually stop as well; it should then really stay offline and not just be connected now and then. What else we set up for older people is described on the page tech help for seniors.
Step by step: the new TV in the right order
The order prevents you from giving consent before you know what it is for. Do not squeeze the setup in between other tasks, and have your Wi-Fi password and the login details for your streaming services ready.
- Read the operating system's terms of use and privacy notices and accept them as far as needed for the internet functions. At every further prompt, look for “Customize”, “More options” or “Decline” instead of “Accept all”.
- Decline content recognition. Watch for wording that refers to viewed content, viewing habits or viewing history.
- Switch off personalized ads and reset the advertising ID.
- Decline usage and diagnostic data; allow program recommendations only if you want to use them.
- Only activate voice control and the microphone if you search by voice. Cover or unplug a camera.
- Switch on automatic updates and check for available updates right away.
- Switch off HbbTV if you do not use the red button, and delete or deactivate preinstalled apps you do not need.
- Set a PIN for settings and app purchases and write down or take a photo of the settings you chose.
| Setting | Typical name | Recommendation | What you lose |
|---|---|---|---|
| Content recognition | viewing behavior, viewing history, program recognition | off | recommendations based on what you watched |
| Advertising ID | ad identifier, interest-based advertising | off and reset | ad tiles tailored to you |
| Usage data | diagnostics, improvement program, statistics | off | nothing for picture and sound |
| Microphone | voice control, voice assistant | off if unused | voice search |
| HbbTV | red button, hybrid TV | off if unused | on-demand library and extra information via the red button |
| Automatic updates | software update | on | nothing, you gain security |
Check again after updates and know the warning signs
Set once does not mean set forever. The BSI recommends reviewing privacy settings critically and adapting them regularly to your own needs (BSI). Good occasions are every major software update, after which new functions or new prompts may appear, and every newly installed app. Take a look at the privacy and advertising settings and compare them with your notes from the initial setup.
The BSI also lists observations that can indicate a compromised device (BSI):
- Unknown or unwanted apps appear on the device.
- The device responds more slowly, and apps suddenly freeze.
- Data usage on your home network is unusually high.
- You can no longer access the associated account.
- The device shows settings other than the ones you chose.
- The TV turns itself on or off for no apparent reason.
If you notice anything like this, reset the TV to factory settings, install the current update, change the password of the manufacturer account and set up the device again. A device can be compromised even without these signs; however, the protective measures described reduce the risk (BSI).
The old TV: reset it before it goes
If the new TV replaces an old one, reset the old set to factory settings before selling, giving away or disposing of it. Sign out of the accounts in the streaming apps first and remove the device from the list of signed-in devices in each service's account settings. A factory reset does not always delete all the data that should go, so checking afterwards is advisable (BSI). The article selling your old phone shows the order of backing up, signing out and erasing, using a phone as the example.
How Technik daheim helps with your new TV
We come to you in the Hildesheim area and the Leine valley, unpack the TV with you and go through the initial setup together: you decide at every prompt, we explain what is behind it. We switch on automatic updates, sort channels and apps, delete what you do not need and set up streaming services and the remote. We write down your choices in plain language so that you know what was set after an update. Everything about the appointment is on the page smart TV and streaming setup; if you want better sound at the same time, see the article clear TV dialogue.
Should the TV go into a guest network, or does the picture stutter when streaming, we will look at the router and Wi-Fi at the same time. If you would rather learn for yourself how good privacy and security settings work on a computer, tablet and smartphone, the data protection course offers the right framework. You can arrange an appointment via the contact page.
