There is no point in debating over the topic how much mobile apps have influenced us. Mobile app world had entirely over the world and through digital technology it hold the power to gain your goals. Now, these applications have access to all the data stored on our phones. And through this information, they can know who users are? where he lives they live?Their family, friends, whatever interests them and what they do.There is a reason why we use passcodes and locks on our phone because we store some confidential data too that we don&#39;t wanna share with anyone. A research shows that almost 70% of the apps are sharing your data with the third party tracking companies like Google Analytics and others. When you download a new application it asks for some permissions. Frankly saying this is totally positive some of the information gathered by the apps are necessary to operate its function for the user. For example, a map app needs to know the location of the user to show the shortest possible way to the destination.The information once collected by the application after the user permission they can share it any other third party service And with this information, the third party tracking companies can know where you are, what are you doing and what you&#39;re planning to do next.Users data sharing Help or Harmful?In order to function, an app not only collect the data from your phone, it needs to send it to the server. The data first collect the application and then send to the server for operating, this means the app can send data elsewhere. The companies collect the data from the app and use it give the user desired result then they use the data further.The companies mostly send the data to the third party tracking services. By encoding the app with functions the developers save the data in the libraries called third-party libraries. These libraries help the developers to acquire user engagement, earn money by ads and agent users through social media.So your personal data is not only for the functionality of the app it&#39;s for more than that. Apps never let the users what libraries they are using to gather the user&#39;s personal information.These libraries using the data from various apps creates a digital profile of the user and store all data in one profile. Consider an app has the permission to go through your contact list while others have permission to examine your calls and messages. These two applications are saving the data at the same third-party library. Then it will combine all the gathered information of a single user and make a digital profile. Even More Data TransactionThe survey reveals that out of the all applications surveyed 15% of the applications were connected to at least 5 third party data tracking companies. These companies not only use the application but also websites to gather the user applications. The technology Cross-device tracking is very useful for these companies to capture user data. With the help of this technology, they can know the even the activities of the user via phone hardware. Google recently found out that many application were using cross-device tracking technology and ultrasonic sound. Google instantly banned the apps from the Play Store.Advice In order to save the data and confidential information being transferred to the company&#39;s best a user can do is check the app settings. By going in the settings of the phone and then in the app permissions section. Check the application have the access to the relevant information only what it actually needed to function otherwise disable the permission.
