I know it has been talked about this many times, but any tips for readers on how to safe guard from such issues? What comes to mind: - don't install apps unless absolutely necessary. - don't let apps have extra permissions when possible. - if app is free - most likely you paid for it somehow (your data) Anything else? I also use 1blocker on iOS to block trackers etc, although, I am not sure if 1Blocker is not spying on my browsing.
