Ever wonder how much Google knows about you?

In the wake of Facebook’s Cambridge Analytica scandal, everyone is now realising the amount of data “free” services collect and its implications. So here’s a little guide and look at Google and its various services.

Every place you have been to (with GPS turned on), since you first used Google on your portable device, is stored by Google. This includes the routes you took, how long it took you to go somewhere and even the date and time of your journey.

Your trips to landmarks and other cities are also actively stored and you can even view data related to trips that you made years ago, even the forgettable ones.

Here is my location data in Islamabad. It shows the places I’ve been to recently and highlights places I usually visit.

You can check your own location data using Google Timeline.

Application Data

Google uses data from all applications you use to create a “profile” for you. That means, it knows how many apps you have on your smartphone, which ones you use often when you use them, and who you use them to interact with.

This helps them know when you go to sleep and of course, who you interact with before sleeping, for example.

Advertisement Profile

Google also has a complete list of your interests and creates your advertisement profile based on your gender, location, age, relationship status, and even recent searches.

This profile is generated from either data compiled from Google Services (Google Search and YouTube) or 2 million+ websites that partner with Google to collect your data.

For example, if you watched a YouTube video related to car repair, Google will note that and start showing you car-related advertisements and vice versa.

You can check your advertisement profile here: Google Ads

Things You’ve Searched And Deleted

All of your searches and history is compiled across all the devices you use and stored in one place. Even if you deleted a browsing session or phone history from one of your device, it could still be saved somewhere in another device.

Remember that this history not only includes Google searches, it also includes data from other services such as YouTube. So whatever kind of videos you watch or things you search for, Google is able to determine your interests and mood depending on your history
