Call blockers sell your data to third parties

Call blockers are a type of application that has gained a lot of ground in recent years. Thanks to a simple application (there are many to choose from) we can block annoying calls. Whether they are advertising or people we do not want to call us.

Why are call blockers dangerous?

The usefulness of this type of applications is more than proven. But several studies are beginning to reveal a part of these call blockers that users will not like too much. It has been revealed that there are cases of applications of this type that are dedicated to collecting data from users.

Call blockers collect data

Apparently, they are not only dedicated to collecting data from users who have such an application installed on their phone. They also subsequently sell the data to third parties. So in addition to obtaining data, which in principle they are doing without having obtained any permission, they also sell it. And that is quite dangerous, since it is not known to whom that data is sold.

In some cases it has been known that the data is sold for commercial purposes. So they generally use them to deliver personalized ads. Although, there may be other, undisclosed cases where other use of the data is made.

Therefore, a call blocker may not be as beneficial. In addition, more and more Android phones give you the option to block a specific number from the system itself, without the need for applications. A simple and much safer option for users.
