Smart TVs promised convenience. They delivered surveillance instead. A detailed analysis from Proton shows these devices capture screen content hundreds of times per hour. They build detailed profiles. And they share the data widely. Even when users try to stop it.
The tracking relies on automatic content recognition, or ACR. This technology takes snapshots of whatever appears on screen. Streaming shows. Live broadcasts. Console games. Even material fed through HDMI ports. It creates a digital fingerprint. Matches it against vast databases. Then sends identifiers to manufacturers and third parties. All by design.
Proton laid out the mechanics in a recent explainer. The company tested popular models. Data flows regardless of opt-out toggles in many cases. Manufacturers such as Samsung, LG, Sony, TCL, Hisense and Vizio no longer sell non-smart versions to consumers. The business model depends on connection. And on the information that flows from it.

But the situation has grown more urgent. In late 2025, Texas Attorney General Ken Paxton sued five major TV makers. The complaint accused them of using hidden ACR to spy on residents. Some brands had ties to Chinese entities. The suits forced clearer consent mechanisms. Yet a July 2026 community test by privacy advocates found the process remains confusing. Roku, for one, bundles voice-command permissions with ACR settings. (Privacy Guides)
Recent enforcement actions have not curbed the appetite for viewer data.
Consumer Reports examined the issue in October 2025. Analysts discovered that ACR and related features collect viewing history, app usage and button presses. The data helps target ads. It also feeds brokers who resell profiles. Turning off the features reduces the flow. But complete elimination proves difficult. Some TVs continue limited collection even after users flip every available switch. (Consumer Reports)
Analytics Insight published updated instructions in May 2026. For Samsung sets, users must dig into Settings > General & Privacy > Terms & Privacy. There they disable Viewing Information Services and Interest-Based Advertisements. LG hides controls under Live Plus. Roku requires unchecking Use Info from TV Inputs. Sony buries Samba Interactive TV options. The menus change names across firmware updates. Casual owners rarely find them. (Analytics Insight)
Proton’s own July 2026 thread on X drove the point home. One user described buying a high-end set. They never signed into accounts. They streamed exclusively from a local media server. The TV still transmitted data thousands of times hourly. “The TV was doing no work they asked for, and a second job nobody agreed to,” the post stated. Another noted that every major brand abandoned pure display models. “A TV with no brain has no business model.” (Proton on X)
The data brokers buy this information. They combine it with location, app opens and voice snippets when enabled. Advertisers then serve hyper-targeted spots. Some profiles influence pricing or content recommendations in ways users never see. And government requests for such data have surged 770 percent in recent years, according to Proton’s April 2026 review of Big Tech transparency reports.
TechRadar highlighted Proton VPN’s 2026 roadmap in January. The company expanded its ad and tracker blocker, NetShield, to Apple TV and other platforms. The feature directly counters smart-TV telemetry. Early tests blocked outbound connections to known data-collection domains. Yet the article cautioned that router-level VPNs remain necessary for LG webOS, Samsung Tizen and Roku units. (TechRadar)
University researchers added weight to the warnings. UC Davis computer scientists documented ACR capturing content in near real time. They measured sampling rates up to hundreds of times per second. The FBI has issued public notices about the risks. Even connected projectors and soundbars sometimes join the data loop. (UC Davis)
So what works? Proton offers three practical paths. First, disconnect the television from the internet entirely. Feed content through a device under user control. A streaming box. A home server via HDMI. The TV becomes a simple monitor. Second, install a Pi-hole or similar network tool to block telemetry domains if connectivity is required for firmware or apps. Third, hunt down and disable ACR and personalized-ad options. Success rates vary. None guarantee zero leakage.
PCMag tested the latest firmware in June 2026. The publication confirmed that a single setting change stops most ACR activity on major platforms. But users must reboot and verify with packet-capture tools. The average owner lacks those skills. (PCMag)
Parents face heightened stakes. Proton’s 2026 survey found 78 percent worry about children’s online privacy. More than half fear reputational damage or effects on future education and jobs. The data collected from family-room TVs often includes children’s viewing patterns. That information moves beyond the living room.
Industry insiders know the economics. Ad revenue subsidizes lower hardware prices. Connected TVs generate recurring income through data licensing. Regulators have begun to push back. The Texas suits and European privacy fines signal tighter rules ahead. But manufacturers update menus faster than watchdogs can audit them.
University College London researchers warned in late 2024 that ACR shares snapshots even when content arrives from external devices. The pattern continues. New 2026 models ship with deeper integration between voice assistants and viewing trackers. (UCL)
Buyers who prioritize privacy now weigh trade-offs. A fully featured smart TV with built-in apps means some level of monitoring. Those who refuse can still buy displays and attach separate streaming hardware. The latter approach restores control. It demands extra setup. And it sidesteps the revenue model that funds ever-cheaper panels.
The evidence piles up. Independent tests. Lawsuits. Academic studies. User reports. They point to one conclusion. Smart TVs track aggressively by default. Opt-out paths exist but remain incomplete and obscure. Until manufacturers treat privacy as a core requirement rather than an afterthought, the living room stays under observation. The escape remains partial at best. Informed owners adjust expectations accordingly.
