Protecting Yourself from Invasive Data Collection Practices

Privacy Security invaded by Fog Data Science

You can minimize the risk of collecting and selling the collected data and geolocation data by taking the following measures:

  1. Disable ad tracking and the mobile ad identification that goes along with it so that data brokers can’t connect any of the acquired data to your particular device.
  2. Limit the number of applications installed on your phone. Many apps collect excessive data not required for functionality (e.g., a puzzle game requesting your location).
  3. Disable location services globally on your phone. You can find instructions on how to do this online or in your device’s settings.
  4. If disabling location services globally is not feasible, consider disabling location services for specific apps that don’t require location data to function correctly.
  5. Use a Virtual Private Network (VPN) that encrypts your internet traffic and hides your IP address. This makes it harder for companies to track your location.
  6. Many companies share your data with third-party advertisers. You can opt out of data sharing by going to the privacy settings of the app or website that you use.

Our Say
