The various online providers, such as:

• Microsoft
• Google
• Apple

are very fond of what you're doing on your digital device. They profit of this and advertise based on your interest to provide you the things you want via targeted advertising.

With this I'm providing you an overview where you can find:

• General Settings of your account / App.
• Your activity which is registered online or via an App.
• Your backups
• And awareness, if you even want to save your data in the cloud.
  
  • And how to prevent this from happening
    • A minor issue in regards to previous remark, is that some functionality might be lost until you enable it again

Curious?
