@dew_the_dew @Darb @Bloomfer @errante @bot If it's a web app, it has little ability to spy - maybe. If it's an app which you download & run as an executable, I think it can spy on you quite easily. The best way is to not download and run apps. For example, a big business model in app development is to package tracking software into benign apps, like a Weather app would make money by packaging a Wi-Fi signal monitoring app which always runs in the background. To reiterate the best way to not get spied on is to not download and run standalone apps on either your phone or PC. But I'm curious what @alex knows about this.
