Modern companies earn on a lot of information about the users and, evidently, they can sell it. Not all users are happy with the fact that their data is stored on servers of some company. Fortunately, there is an opportunity to see what, for example, Google knows about you. A collection of links about this information is published in the Cloud Fender blog .Some data can even be removed.
Google draws your portrait
Google tries to create a user’s “portrait” basing upon age, gender and interests. Running the social network Google+ and the integration of its profiles in all the services of the company, should simplify this task. This data is used to display relevant ads. You can check it here: http://google.com/ads/preferences.
You can change these data or to disable such Google services, like Search, e-mail Gmail, YouTube and Google Maps.
Google keeps track of your movements
If you use an Android smartphone or tablet, Google can track your movements by the coordinates. The whole history of your travels and trips can be viewed on the link maps.google.com/locationhistory. History of movements can be downloaded as a file. Below you can see an example of one of the movements of Reddit users, which was engaged in pizza delivery for a month.
Google sees what you are looking for online
Google saves the history of your search, as well as the information about which ads you clicked. In the settings at the right top, you can delete the records about the history of the search for a certain period of time. You can explore your favorite websites and requests (based on search history).
All these data you can see here: history.google.com.
Google knows what devices were connected to your account
It’s a pretty useful link
security.google.com/settings/security/activity – clicking on it, you can see a summary of who and with which devices was connected to your account. Also, there you can check the IP connectivity, browser version and location. Similar reports can be viewed in other Google services. For example, at the bottom of Gmail there is a link to “Additional Information”. It opens a detailed summary of who logged in your account:
Applications also have access to your data
Here you can check which applications and add-ons may have such a success: security.google.com/settings/security/permissions. The link is useful because here it is possible to cancel the permissions for applications to use your data.
All data can be exported out from Google
This applies to e-mail data, contacts, calendar, files from Google Drive, photos, bookmarks, etc. You can upload them to another site to keep in your archive (if you, for example, decided to delete your account in Google). Then you get several zip-files. For example, the contacts can be exported in a vCard format, which is supported by most e-mail clients, including Apple Mail and Microsoft Outlook.
