Ad-/Tracking-Modules and Privacy Checker

That's not only annoying in many cases, but also a general security risk – as ad- and tracking-modules inherit all permissions from their „host-apps“. Moreover, there are other hidden costs of advertisements: with websites, they at best make up 50% of your traffic, in some cases more than 90%! Not to forget that sometimes there are also malicious ads – something Google Ads isn´t safe from either. So what can be done?

  1. Buy apps. Usually, the paid versions do not contain ad-modules (exception: if the paid version is to be used as an addon to the free one; but unfortunately there are also other exceptions).
  2. If there's no paid version (or that contains „sniffers“ as well): think about using an AdBlocker (in most cases, this requires root)
  3. Alternatively, think about using a Firewall or Permission Blocker.
  4. Take your apps exclusively from F-Droid (in my lists they can be identified by the F-Droid Icon F-Droid Icon). According to a study from 9/2017 this is the only place where neither Adware nor Malware was found (at Google Play they found e.g. ca. 2% Malware)

And if you think it’s only the online shops which are bugged: Nope. In offline stores, secret surveillance tracks your every move as well.

To protect yourself against that, you’ve first got to identify affected apps and places.

I need privacy. Not because my actions are questionable, but because 'your' judgement and intentions are.

And it doesn't matter whether or not my communications are weighty or frivolous in nature - they are mine and only for those whom I've chosen to share them with. Not the government's, nor goog's, nor my ISP's, but mine.

Also, what is legal where I live today, may not be legal tomorrow and my discussion of it may incriminate my future self. It has happened in the past many times to others in other places.
