1. Free VPNs
Using a Virtual Private Network is one of the best ways you can create an encrypted, safe connection to the internet that helps keep your data safe. But it stands to reason that a service this helpful would come at a cost. Be suspicious of free VPN services — they have to turn a profit in some way, and that way might just be by selling your data. These free VPNs are often created by lesser known companies that may even lack the resources needed to properly guard your data. When in doubt, spend a little to ensure you’re getting a quality VPN in return.
2. Social Media Apps
Several social media apps, including Facebook, Instagram, Snapchat, and Twitter, have come under attack for collecting users’ data and profiting from it. Like many free apps, these are trying to make money somehow, and your data allows them to sell information about you, including your location and preferences, to advertisers. These advertisers can then send you more targeted ads based on the data they’ve accumulated about your life.
If you’ve ever wondered how Facebook knows you’re looking for a pair of black sneakers or are trying to book a trip to Hawaii, wonder no more.
3. Free Messaging Apps
If you’re sensing a theme here it’s that any free apps is more likely to use your data in ways that turn a profit. Free messaging apps seem like they should be private and secure, but concerns have been raised that those relying on advertising revenue may track user data and target ads to its users. The more secure and encrypted a messaging app is, the better. Some examples of end-to-end encrypted messaging apps include Signal, WhatsApp, and Telegram.
