Understanding Smart Device Privacy: What You Should Know

Smart devices have become a regular part of many homes and workplaces. Smartphones, tablets, smart speakers, fitness trackers, and connected home devices collect and store information about how we live our daily lives. According to a 2023 Pew Research Center survey, 72% of American adults own a smartphone, and about 28% of households have at least one smart speaker device. These devices offer convenience, but they also collect data that you should understand and manage.

When you use a smart device, it gathers various types of information. This may include your location, browsing history, apps you use, contacts, photos, voice recordings, and information about your physical activity and health. Some devices collect this data to provide their core functions. A fitness tracker needs to know your movement to count steps. A weather app needs your location to show local forecasts. However, companies may also collect data for other purposes, such as marketing, research, or selling to third parties.

Privacy settings are the tools built into your devices that let you control what information is collected and who can access it. These settings vary by device type and manufacturer. An iPhone has different privacy controls than an Android phone. A smart speaker has different settings than a laptop. Learning where these settings are located and what they do gives you more control over your personal information.

Understanding smart device privacy matters because data breaches occur regularly. In 2022, over 422 million people worldwide experienced data breaches, according to Identity Theft Resource Center data. When your personal information is exposed, it can lead to identity theft, fraud, unwanted marketing, or other problems. By managing your privacy settings, you reduce the risk that your information will be misused.

Practical Takeaway: Take time to identify which smart devices you own and use regularly. Make a list of what types of data each device likely collects—location, contacts, photos, voice, health information, or browsing history. This inventory will help you prioritize which devices to review first.

Privacy Settings on Smartphones and Tablets

Smartphones are often the devices that collect the most personal information. They know your location, your contacts, your photos, your calendar, your health data, and which apps you use and when. Both Apple iOS and Android devices have built-in privacy controls, though they work differently.

On an iPhone or iPad running iOS, go to Settings and look for Privacy. Apple's privacy settings let you control which apps can access specific features like Location Services, Camera, Microphone, Contacts, Calendar, Photos, Health, and Fitness data. For each feature, you can see which apps have requested permission and what level of access you gave them. You can deny permission, allow it only while using the app, or allow it always. Apple reports that since 2021, they have required apps to show a privacy label that discloses what data they collect, similar to ingredient labels on food.

Android devices work similarly but with some variations depending on whether you have a Samsung, Google Pixel, or another brand. Go to Settings, then look for Apps or Application Permissions. Here you can see which apps have permission to access your location, camera, microphone, contacts, and other sensitive information. You can grant or revoke these permissions for each app individually. Android allows you to give permissions only while using an app, rather than all the time, which provides better control.

Location Services deserve special attention. Many apps request access to your location even when they do not need it for their core function. A social media app or a shopping app does not need to know your exact location to function, but they may want this data for marketing purposes. You can turn off Location Services entirely, or you can manage permissions per app. Allowing location access only "While Using the App" rather than "Always" is a common recommendation.

Another important setting is App Tracking Transparency on iOS or Tracking Preferences on Android. These settings control whether apps can track your activity across other apps and websites. Disabling this tracking limits how much third parties can learn about your online behavior. On iOS, you can go to Settings, Privacy, Tracking, and toggle off "Allow Apps to Request to Track." On Android, the equivalent is found under Privacy settings and often called "Personalization Ads" or similar.

Voice Assistant settings also matter. If you use Siri (iOS), Google Assistant (Android), or another voice assistant, these services record voice commands. You can review and delete voice recordings. On iPhone, go to Settings, Siri & Search, and look for options to delete Siri history. On Android devices with Google Assistant, visit myactivity.google.com and delete voice recordings you do not want stored.

Practical Takeaway: Spend 15 minutes reviewing your smartphone's app permissions. Go to your Privacy or Apps settings, review the permissions you granted, and deny access to any apps that do not need specific information like location or microphone access to work properly. Pay special attention to social media and advertising apps.

Managing Privacy on Smart Home Devices

Smart home devices like Amazon Echo, Google Home, and similar products have become common. These devices use always-on microphones to listen for voice commands. According to Amazon, their devices only record after they detect the wake word, but many users have concerns about what data is collected and how it is stored.

Smart speakers collect voice recordings, which are stored on company servers. Amazon and Google allow you to review and delete these recordings. For Amazon Echo devices, open the Alexa app, go to More, Settings, Alexa Privacy, and review your voice history. You can listen to individual recordings, delete specific ones, or set automatic deletion. You have options to delete recordings every 3 months, every day, or you can disable this automatic deletion if you prefer to delete manually.

Google Home works similarly. Visit myactivity.google.com, filter by "Google Assistant," and you can view and delete your voice recordings and search history from Google Assistant commands. You can also set automatic deletion to remove old recordings automatically.

The microphone itself presents a privacy concern for some users. Both Alexa and Google Home devices have a physical mute button. When activated, the microphone is electronically disabled, which prevents the device from listening. Many people physically mute their smart speakers when not in use. Some prefer to unplug the device when it is not needed.

Camera-enabled smart home devices like video doorbell cameras and indoor cameras present additional privacy issues. These devices record video and audio of areas inside and outside your home. Make sure that the username and password for these devices are strong and unique. Use two-factor authentication if the manufacturer offers it. Review your camera's privacy settings to see who can view footage and whether footage is shared with other people or services.

Smart home device manufacturers partner with third-party services. For example, your smart speaker might work with your smart thermostat, lighting, or lock. Review what data is being shared between devices and services. Many devices have settings where you can disconnect third-party integrations you do not use.

Location data from smart home devices can also be a concern. Some smart devices track when people are home or away. Make sure you understand what location data is collected and how it is used. In your device's app, look for location settings and restrict them if needed.

Practical Takeaway: Review the voice history on any smart speakers in your home. Delete any recordings you are not comfortable with. Set automatic deletion to your preferred timeframe (daily, monthly, or every 3 months). If your device has a mute button, keep it muted when you are not actively using voice commands.

Controlling Privacy on Computers and Web Browsers

Computers and laptops collect data through operating systems, web browsers, and installed applications. Windows PCs and Mac computers both have privacy settings that control what information is collected about your device use and sent to Microsoft or Apple.

On Windows 10 and 11, go to Settings, then Privacy & Security. Here you will find options for General, Speech Recognition, Inking & Typing, Diagnostics & Optional Diagnostics, and more. The Diagnostics section is particularly important—Microsoft collects diagnostic data about your device's performance and how you use Windows. You can set this to Diagnostic Data (minimum), Required Diagnostic Data, or Full Diagnostic Data. Choosing the minimum level reduces data collection. Under Activity History, you can also disable tracking of your activities and search history.

On Mac computers, go to System Preferences (or System Settings in newer versions), then Privacy & Security. Similar to Windows, you can control what data Apple
