5 Phone Settings to Limit App Data Collection | SlashGear

The relationship between smartphone users and their devices has fundamentally shifted since the launch of the Apple App Store in 2009. What began as a convenient way to expand phone functionality has evolved into a constant stream of data collection, often without users fully understanding the extent of it. While data collection is now commonplace, many users accept it as an unavoidable consequence of modern life. However, a number of adjustments to phone settings can significantly limit the amount of data apps collect, requiring no specialized technical knowledge.

Restrict Permissions Scopes for Individual Apps

Modern smartphone operating systems, both iOS and Android, are designed with built-in constraints to limit excessive data collection by app developers. A key component of this control is managing app permissions – dictating which parts of your phone an app can access. When an app requests access to sensitive features like your camera or location, you should carefully consider whether the request is justified. Granting permissions indiscriminately can expose your data unnecessarily.

Both iOS and Android provide tools to review and manage app permissions. On iOS, navigate to Privacy & Security to see a list of permissions and which apps have utilized them. Android users can find similar information under Settings, then Security and Privacy, and finally Permissions Used In Last 24 Hours. Alternatively, you can check permissions on a per-app basis within the settings menu.

Android users also have access to a setting called “Usage Data Access” found under Special Access within the Apps menu. This permission allows apps to track how you use your phone. Disabling this setting for all apps can further limit data collection, though some apps may require it to function correctly.

Opt Out of Ad Tracking

A primary driver of app data collection is advertising. Developers leverage user data to target ads, and the advertising industry relies on anonymized identifiers to track user behavior across apps and websites. While Apple has implemented features that prompt users to opt-in to ad tracking, Android historically has been more permissive.

On Android, you can limit ad tracking by going to Settings, then Google, then All Services, and finally Ads. Deleting your advertising ID prevents the creation of a personalized advertising profile. While there, it’s also advisable to disable “Usage & Diagnostics” to prevent Google from tracking your app usage. On iOS, you can prevent app tracking requests entirely by toggling off “Allow Apps to Request to Track” under Settings, then Privacy & Security, then Tracking.

However, the most effective way to avoid tracking is to be mindful of the apps you install. Both the App Store and Google Play Store now provide information about an app’s data collection practices before you download it. Reviewing this information can help you make informed decisions about which apps to trust.

Change In-App Privacy Settings

Beyond the operating system-level controls, many apps offer their own privacy settings that can further limit data collection. These settings are often buried deep within the app’s menus, and the language used can be intentionally vague. However, taking the time to explore these settings can yield significant privacy benefits.

For example, Instagram’s settings allow you to manage the data used for ad personalization. TikTok offers toggles to disable targeted ads both within the app and across other websites. Similarly, DoorDash allows you to opt out of ad personalization. The specific settings and their locations will vary from app to app, but it’s worth investigating each app’s privacy options.

Turning Off Data Collection on Samsung Galaxy Devices

Samsung Galaxy devices include additional data collection settings specific to the Samsung ecosystem. These settings, while not applicable to iPhones or other Android phones, are important for Samsung users to be aware of.

Within the Security and Privacy section of the Settings app, you can disable “Personal Data Intelligence” and “Send Diagnostic Data.” Under Account Security, you can disable “Get News and Special Offers” and “Improve Personalized Ads With Samsung Account Data.” the “Customization Service” should be disabled in both the main Settings menu and within individual Samsung apps like Calendar, Clock, Gallery, and My Files.

Delete Apps You Rarely Use

Perhaps the simplest and most effective way to protect your data is to uninstall apps you no longer use. Every app installed on your phone represents a potential source of data collection. Regularly reviewing your app library and removing unused apps can significantly reduce your digital footprint.

On iOS, you can delete apps by long-pressing the app icon and selecting “Remove App,” then “Delete App.” On Android, you can uninstall apps through the Google Play Store or by navigating to Settings, then Apps, and selecting the app you want to remove.

protecting your data requires a proactive approach. By taking the time to adjust your phone’s settings and be mindful of the apps you install, you can significantly limit the amount of data collected about you and regain control of your digital privacy.
