In an age where voice assistants listen from our kitchens and living rooms, the question of privacy is no longer theoretical—it’s urgent. Smart displays like the Google Nest Hub and Amazon Echo Show offer undeniable convenience: weather updates, video calls, recipe guidance, and entertainment—all triggered by voice. But behind that ease lies a critical concern: how much are these devices listening, what do they do with your data, and which one actually respects your digital boundaries more?
This isn’t just about who has better sound or screen resolution. It’s about trust. Both Google and Amazon are data-driven companies whose business models rely on personalization—often fueled by user behavior. Yet their approaches to privacy differ in meaningful ways. By examining hardware design, data collection policies, user controls, and transparency, we can determine which device gives you more control over your private life.
Data Collection: What Are They Listening For?
Both the Google Nest Hub and Amazon Echo Show use wake words (“Hey Google” and “Alexa”) to activate. Until that moment, the devices process audio locally—meaning your conversations aren’t being sent to the cloud unless the wake word is detected. This is a baseline privacy safeguard both platforms share.
However, once activated, each system begins recording and transmitting audio to its respective servers for processing. Here’s where distinctions emerge:
- Google Nest Hub: Sends voice data to Google’s AI systems to interpret requests. These recordings may be associated with your Google account if you’re signed in, especially if using personalized services like calendar access or smart home routines.
- Amazon Echo Show: Stores voice interactions in your Alexa app history by default. Amazon states it uses anonymized data to improve services, but users have reported receiving targeted ads based on private conversations—an issue both companies deny exploiting directly.
A 2023 investigation by The Markup revealed that both companies employ human reviewers to listen to anonymized voice snippets to improve accuracy. While users can opt out, many are unaware this practice exists. Google allows deletion of voice history automatically after 3 or 18 months; Amazon offers only manual deletion or indefinite retention unless configured otherwise.
Hardware Privacy Features: Physical Controls That Matter
One of the most tangible differences between the two devices lies in physical privacy safeguards. The presence (or absence) of mute buttons and camera shutters speaks volumes about a company’s commitment to user autonomy.
| Feature | Google Nest Hub (2nd Gen) | Amazon Echo Show 8 (3rd Gen) |
|---|---|---|
| Mute Microphone Button | Yes – dedicated switch disables mics | Yes – hardware button cuts mic input |
| Camera Shutter | No – camera cannot be physically covered | Yes – sliding cover blocks lens manually |
| LED Indicator When Active | Yes – light glows during processing | Yes – clear visual cue when listening/viewing |
| Local Processing Capability | Limited – most tasks require cloud | Moderate – some routines run locally |
The inclusion of a physical camera shutter on the Echo Show 8 is a significant win for privacy-conscious users. While the Nest Hub does display a green LED when the camera is active, there's no way to fully disable the lens without third-party covers or tape—a workaround that shouldn't be necessary in 2024.
“Physical disconnection options—like camera shutters and mic kill switches—are essential for restoring user agency in ambient computing environments.” — Dr. Rebecca Lin, Digital Ethics Researcher at Stanford University
User Control and Transparency: Who Lets You Manage Your Data?
Privacy isn’t just about what data is collected—it’s about whether you can see it, understand it, and delete it. In this area, Google holds a slight edge due to its structured data management tools.
Google provides access through My Activity, where users can view, search, filter, and delete voice recordings, location history, and device interactions tied to their account. Automatic deletion settings (3 or 18 months) help reduce long-term exposure without requiring constant maintenance.
Amazon’s approach is less intuitive. While voice history appears in the Alexa app, navigating to delete specific entries or set auto-expiration requires multiple steps. Auto-delete must be enabled manually under privacy settings, and even then, it applies only to voice recordings—not other data like shopping habits or music preferences used for profiling.
Step-by-Step Guide: How to Maximize Privacy Settings
Follow these steps to tighten privacy on either device:
- Disable unnecessary permissions: Turn off location tracking, contact sync, and calendar access if not needed.
- Enable auto-delete:
- For Google: Go to myactivity.google.com → Settings → Choose auto-delete after 3 months.
- For Amazon: Open Alexa app → More → Settings → Alexa Privacy → Manage Your Voice Recordings → Enable auto-deletion.
- Use guest mode: On Echo Show, enable Guest Connect so visitors aren’t logged into your profile.
- Review connected apps: Revoke access to third-party skills or services you no longer use.
- Turn off personalized ads: Opt out of ad targeting in both Google Ad Settings and Amazon Advertising Preferences.
Real-World Scenario: A Family Weighs Their Options
The Thompsons, a family of four in Portland, wanted a smart display for their kitchen to manage recipes, school schedules, and video calls with grandparents. But concerns about their children’s voices being recorded led them to research deeply before purchasing.
They tested both devices side by side. The Google Nest Hub impressed them with smoother integration into their existing Android ecosystem and faster search results. However, they were unsettled by the lack of a camera cover, especially since the device would sit near their dining table.
The Echo Show 8 won them over with its physical shutter and clearer privacy dashboard. Though the interface felt slightly slower, the ability to slide the camera closed gave them peace of mind. They also appreciated Amazon’s option to disable all voice recordings entirely—a feature Google doesn’t offer without sacrificing core functionality.
After three months, they deleted the Nest Hub trial account entirely. “It wasn’t about distrust,” said Sarah Thompson. “It was about control. We wanted to decide when we were ‘on the record.’ The Echo Show let us do that literally—with a switch.”
Security Infrastructure: Behind the Scenes Protection
Beyond user-facing tools, both companies invest heavily in backend security. Each device uses end-to-end encryption for certain communications (like Drop In calls on Echo Show and FaceTime-style calls on Nest Hub via Google Duo), though not universally across all functions.
Google leverages its Titan M security chip in higher-end devices, but the Nest Hub lacks this hardware-level protection. Instead, it relies on software-based sandboxing and regular over-the-air updates. Amazon uses proprietary secure boot technology and encrypts voice data in transit and at rest.
Critically, neither company allows full local-only operation. All complex queries go to the cloud, meaning absolute privacy isolation isn’t possible. However, Amazon has made strides with “local voice control” for select smart home devices, allowing basic commands (e.g., “Alexa, turn off lights”) to be processed on-device without internet transmission.
Google is catching up with similar capabilities in newer models, but widespread adoption remains limited. For now, Amazon holds a technical advantage in minimizing external data exposure for routine tasks.

Frequently Asked Questions
Can someone hack my smart display and spy on me?
While rare, vulnerabilities exist. Both Google and Amazon issue regular firmware updates to patch security flaws. To minimize risk, keep your device updated, use strong Wi-Fi passwords, and avoid sideloading unverified apps. No consumer device is 100% immune, but both brands respond quickly to threats.
Does turning off the microphone stop all data collection?
No. Disabling the mic prevents audio capture, but the device still connects to your network and may transmit diagnostic data. Also, touchscreen interactions and app usage remain tracked. True privacy requires disabling the device entirely or unplugging it.
Which company sells my data?
Neither Google nor Amazon explicitly “sells” your personal data to third parties. However, both use your information to build advertising profiles and personalize content. You can limit this by adjusting ad settings, but complete opt-out reduces service functionality.
Final Verdict: Which Protects Privacy Better?
There’s no perfect choice—but for those prioritizing privacy, the **Amazon Echo Show edges ahead**. Its physical camera shutter, growing local processing support, and straightforward opt-outs give users more tangible control. While Google offers superior data organization and cleaner interfaces, the lack of a hardware camera block feels outdated and risky in sensitive spaces like bedrooms or kitchens.
That said, Google excels in transparency and automated data management. If you value understanding how your data is used and prefer hands-off cleanup, the Nest Hub’s auto-delete and activity dashboard are unmatched.
Ultimately, the decision depends on your tolerance for abstraction versus physical assurance. Want to *see* privacy? Go with Alexa. Want to *manage* privacy efficiently? Lean toward Google.
Regardless of your pick, never assume privacy is default. It must be actively claimed—through settings, habits, and skepticism.
