Cell phone tracking is a complex web that involves many mechanisms and an even larger number of entities. The main actors who collect the data:

  • the network service provider
  • phone manufacturer and operating system
  • apps and other programs
  • The Pirates
  • state authorities

If you have an iPhone or an Android phone, the device and its operating system are built by the same company. Other common smartphones usually have the Android operating system. This is the case for a Samsung, Huawei, Lenovo, Oppo or other branded device. Others work with IOS like the Iphone.

This usually means that these devices have software from Google and the manufacturer, both of which are capable of collecting your data.

Although Android is developed by Google, it is an open source operating system in its essence. This System for Android (AOSP) releases the code openly, and it is suitable for training a number of other programs. These range from the Kindle Fire eReaders operating system, which sends data to Amazon, to LineageOS, which is a minimally invasive version of Android.

Data collection on Android devices with Google Mobile Services

The most common form of Android on smartphones comes preinstalled with Google Mobile Services (GMS) and Google Play Services. Virtually every Android smartphone you normally see, from Samsung Galaxy to Motorola, is linked to Google.

In most of these smartphones, this combination of Android and GMS is supplemented by the software of the manufacturer of the device (unless it is a Google Pixel).

While brands like Samsung offer a number of their own data collection apps, such as Samsung Pay or Bixby, these are lesser when compared to Google’s entire data collection ecosystem.

The device manufacturer also has access to it.

Data collection by Google

You can download the data that Google has collected about you through your Google Account dashboard. This also allows you to see all your connected services in a single space.

The file that Google will send you will provide you with a plethora of data with things like:

  • Location history
  • In-app activities
  • Your internet searches
  • The videos you have watched
  • Your contacts
  • Your emails

Because Google Play Services and the Play Store are integral to downloading and running apps, the search engine can also access data about other apps.

Data collection by Google on iPhone

If you have an iPhone but still use services like Chrome, YouTube, Google Maps, or Gmail, Google will still get data through those apps. You might want to check what data Google is able to collect through your iPhone by following the steps listed in the previous section.

Only, using Chrome and Google’s extensive web advertising infrastructure indicates that iPhones continued to send around 50 requests per hour to Google’s servers, totaling almost 6MB. The majority of this data was for calls to advertising domains.

Are AIs listening to us?

Sometimes we can ask our personal assistant about tomorrow’s weather or even call our friend without even dialing the number. Only, in some cases, the one you call Siri or Alexa are veritable goldmines for ad targeting. In the program “Behind our smokescreens” published on Netflix, a former Google employee reveals: “Google and Facebook create for each user a digital double”

Are social networks affected?

You have certainly happened to do a search on Google and find your social network, Facebook, Instagram or Tiktok offering you advertisements related to what you were looking for. “Applications are a bit like the Wild West,” says Mathieu Cunche, researcher in the protection of personal data. The specialist gives an example to illustrate this phenomenon, your games application A is active and through a small software contained in the application, it connects to application B, which is your favorite social network. The expert explains “through subterfuge well buried in the architecture of our favorite applications” our data is sucked up so that companies can better target their offers and their audience.
