What can you do
The permissions you see every time you install the application are obviously useless. According to a new analysis, applications on smartphones send large amounts of information for advertising and analytical purposes. Can you defend it?

If you have a new application installed on your phone, you will be notified of the required authorization. For example, if you don't want the weather app to have access to your contacts, you can prevent personal authorization. We believe that mobile operating systems such as Apple iOS and Android actually only provide specified data to applications. According to Cnet's report, this is not entirely true.
On the contrary: Apps on smartphones always seem to ignore authorization. Even if certain permissions were denied, researchers were still able to identify about 1,000 applications that were transmitting data. To that end, they analyzed the transfer protocols of their phones and were able to find out where the applications were sending messages that were actually blocked.
Who gets the data?
According to Cnet, this data is collected and evaluated primarily by advertising companies and government agencies. Specific locations are very profitable for advertising purposes, and applications such as AccuWeather send location information even if the location function of the phone is turned off. As Zdnet revealed in an article, the app then uses device tracking over the WiFi network to find the location of the device.
AccuWeather is one of the most popular weather apps in the AppStore and Google Play Store. With over 50 million downloads on Android and close to 13,500 reviews in the AppStore, it's clear how many devices the app sends to third parties.
What can you do
Protecting yourself from the transmission of user data is difficult. Of course, you cannot install certain applications on your phone at all. However, even with pre-installed applications, researchers are still able to find user data transfers that go beyond the authorization.
