"But if the app is sending the location data to an external server, that could pose some interesting questions."

In case users are wondering why apps may have these additional services running behind it, Taflan says that it may be due to someone collecting data and potentially displaying "aggressive" advertising.

As such, Taflan does not want to suggest that people will be seeing malicious apps in the future, but sees "very targeted" advertising becoming more prevalent.

"It might reach the point where a user might be passing by a storefront and they will get automatically spammed with advertising," he said.

By using an app such as Clueful, Taflan hopes that users will be able to use its function to look under the hood of every app and see what is really going on, and then make a decision of whether is it safe or not.
