Why You Need to Block Apps from Tracking Personal Data

We need to block apps from tracking personal data because it poses a threat to our privacy and security. With the advancement of technology, apps are becoming more intrusive, and they are collecting more data than ever before. Here are some reasons why you need to block apps from tracking your personal data:


– Enhances your privacy
– Protects you from potential data breaches
– Prevents apps from sharing your data with third-party companies
– Minimalizes tracking your internet activities
– Compatible with Android devices

Method 1: Changing App Permissions

The first method to block apps from tracking our personal data is by changing our app permissions. We can manage app permissions on our Android devices by following the steps below:

1. Open the ‘Settings’ app on your phone.
2. Click ‘Apps and Notifications’ from the menu options.
3. Select the app that you don’t want to track your personal data.

Method 2: Using a Firewall

A firewall is a program that monitors and controls access to and from your device. With a firewall, we can control which applications can connect to the internet, and we can block the access of any application that we don’t want to track our personal data. To use a firewall on our Android devices, we can follow these steps:

1. Install a Firewall application from the Google Play Store.
2. After installation, open the app and set it up to monitor all internet traffic.
3. Go to the "Applications" tab and select the application that you don’t want to track your personal data.
4. Click on "Block" on the right side to prevent the app from accessing the internet.

Method 3: Using a Privacy Protection App

Using a privacy protection app can be an efficient method to block apps from tracking personal data on Android devices. These apps use machine learning algorithms to detect the applications that track your personal data and allow for personalized controls. Here’s how to use a privacy protection app:

1. Install a privacy protection app, such as Privacy Knight, from the Google Play Store.
2. Launch the app and create an account.
3. The application will automatically scan your device and detect all the applications that use your data.
4. Use the app to control and manage the data permissions of all the applications on your phone.

What to Do If You Can’t Block Apps from Tracking Personal Data?

Sometimes, you may encounter a situation where you cannot prevent an app from tracking your personal data. In this case, you can take the following steps to minimize the amount of personal data that the app collects:

– Check App Permissions: Check the permissions granted to the app and revoke access to unnecessary permissions.
