You wake up in the morning and, first thing, you open your weather app. You close that pesky ad that opens first and check the forecast. You like your weather app, which shows hourly weather forecasts for your location. And the app is free!
But do you know why it’s free? Look at the app’s privacy settings. You help keep it free by allowing it to collect your information, including:
What devices you use and their IP and Media Access Control addresses.
Information you provide when signing up, such as your name, email address and home address.
App settings, such as whether you choose Celsius or Fahrenheit.
Your interactions with the app, including what content you view and what ads you click.
Inferences based on your interactions with the app.
Your location at a given time, including, depending on your settings, continuous tracking.
What websites or apps that you interact with after you use the weather app.
Information you give to ad vendors.
Information gleaned by analytics vendors that analyze and optimize the app.
This type of data collection is standard fare. The app company can use this to customize ads and content. The more customized and personalized an ad is, the more money it generates for the app owner. The owner might also sell your data to other companies.
Many apps, including the weather channel app, send you targeted advertising and sell your personal data by default.

The company, which operates Facebook, Instagram and WhatsApp, is worth US$1.48 trillion. Just under 98% of its profits come from advertising, which leverages user data from more than 7 billion monthly users.

Before mobile phones gained apps and social media became ubiquitous, companies conducted large-scale demographic surveys to assess how well a product performed and to get information about the best places to sell it. They used the information to create coarsely targeted ads that they placed on billboards, print ads and TV spots.
Mobile apps and social media platforms now let companies gather much more fine-grained information about people at a lower cost. Through apps and social media, people willingly trade personal information for convenience. In 2007 – a year after the…
