Mobile applications have become essential to our daily lives which provide convenience and connectivity. However, many apps may collect our data more than what is necessary without your knowledge. This data can include sensitive information such as location, contacts, browsing history, and financial details.
Unauthorized data collection poses serious risks, including identity theft, targeted advertising, and privacy breaches. To safeguard personal information, it is crucial to understand how apps collect data and take proactive steps to control access. This guide provides essential steps to help users identify and prevent excessive data collection by apps, ensuring better privacy and security in the digital space.
Prevent Unauthorized Data Collection
Step 1: Review App Permissions.
Use a web browser on a computer or mobile device to access the official Google Play store. Search for the app you want to install. Scroll down to the App Permissions section and carefully review the permissions that apps request before installing.
Step 2: Read the Privacy Policy.
Before installing an app, it is essential to review its privacy policy to understand how your data will be collected, stored, and shared. Under the “About this app” you will find a link to the app’s Terms and Policies.
Afterward, click the link to be redirected to the app’s Terms and Policies. Read it carefully to ensure you understand how your data will be used.
Step 3: Use Limited or Temporary Permissions.
Open “Settings” on your device. Go to “Applications and Permissions” and select “App Manager". Tap on the installed app to view its permissions. Deny unnecessary permissions that are not required for the app to function properly.
Step 4: Disable Background Data Collection.
Some apps continue to collect data even when they are not actively in use. To turn this off, go to the App's Info then click “Data Usage”. Under Network Management, uncheck Mobile Data and Wi-Fi for the apps you don’t want to use background data.
Step 5: Be Cautious with Third-Party Logins.
Many apps offer third-party login options like Facebook, or Google, which can grant them excessive access to your personal data. To protect your privacy, use a unique login whenever possible and regularly review and revoke access to unused apps.
Step 6: Regularly Delete Unused Apps.
Unused apps can still collect data in the background, posing a privacy risk. Regularly review and uninstall apps you no longer use to minimize data exposure and free up storage space.
Step 7: Keep Your Device and Apps Updated.
Regular updates include security patches that protect your device from vulnerabilities and unauthorized data access. Enable automatic updates to ensure your apps and operating system stay secure.
